Hey there. 😉

I decided to put together a little custom rig recently, mostly because a friend of mine handed me an old motherboard she wasn't using anymore, and I figured, why not see what I could do with it?
Intel Core i5-2500K
I'm sitting here looking at my setup, and I’ve somehow ended up with just 3.0 GB of DDR2 RAM to work with.
I’ve been digging through some older hardware lately, specifically looking at this ALiveNF7G-FullHD R3.0 AM2/AM2+ motherboard, and I can't help but feel a little nostalgic for the era when things were just slightly less complicated than they are today. It’s one of those pieces of kit that really makes you appreciate how far we've come, though sometimes I wonder if we lost a bit of that simple charm along the way.
I’ve been looking into this LC6550GP2 V2.2 550W Green Power power supply unit, and honestly, I find myself wondering if anyone actually relies on these things for anything serious anymore. It’s one of those units that feels like it belongs to a different era of PC building, back when we weren't quite so obsessed with every single watt of efficiency or the massive power draws of modern GPUs. It's a decent enough little component if you're just trying to get an old machine up and running, but I suppose if you're planning on throwing a high-end Nvidia card in there, you might want to look for something a bit more robust. It's fine for a basic setup, though I can't help but feel a little nostalgic for the days when hardware was a bit more straightforward, even if it meant dealing with much less efficient power delivery.
Everything seems to be running perfectly fine on my end—temperatures are looking good and nothing is showing any signs of overheating.

So, I’ve run into a bit of a headache: my dedicated graphics card is stuck running off the integrated graphics because my PCI Express x16 slot seems to have completely given up on life. 🙂
I’m running into a bit of a nightmare here where absolutely none of my graphics cards are working; I've gone through several different ones now—all perfectly functional, mind you—but nothing seems to take.
I've got one right here at home that I know for a fact works perfectly, and to top it off, I even had someone from Craigslist swing by yesterday to check it out.
It looks like I’m running into the same issue with the graphics card, which really points to a problem somewhere along the PCI Express slot itself. I actually reached out to a friend to see if she had ever successfully run a GPU on this specific motherboard, and she mentioned that she has, so it’s clearly not just a dead board.
I honestly haven't a clue; she probably just stuck with the integrated graphics and called it a day. I did try blowing out the slot a few times to clear out any dust, but that's about as far as I got with it.
Still nothing. I tried pulling the battery to reset things and went into the BIOS to manually set the primary PCI Express slot for the graphics card, but it’s just not budging.

So, there's one thing I should probably mention—when everything is plugged directly into the graphics card, the fan spins up perfectly fine without any drama.
The PCI Express slot is actually showing some signs of life, and I’ve even managed to boot right into Windows—though, naturally, there's absolutely no video signal to speak of. Still, hearing that familiar startup sound tells me the system is actually loading the OS, which gives me a little glimmer of hope that we might actually get somewhere with this.
I suppose I could try a BIOS update to see if that clears things up, though honestly, I’m not holding my breath that it'll actually make a difference.
I mean, let’s be real here—it’s not just one faulty card; it feels like if I tried to plug in a hundred different graphics cards right now, not a single one of them would actually work.
It really ought to work regardless of whether I decide to mess with a BIOS update or not; on my last ancient motherboard, I could have tossed in just about any graphics card under the sun—whether it was an AMD or an Nvidia card—and it would have worked without a single hiccup.
Everything was working perfectly fine before this. ☕ They were working perfectly fine before I went ahead and updated the BIOS, so... that's just great.

So, if anyone out there actually has a clue what else I might be able to try... I’m really hoping to avoid swapping out the motherboard again, though it seems like my only option if that PCI Express slot is truly dead. I've been digging around to see if...
The capacitors around it look like they’ve been blooming or bulging, but honestly, they aren't... so I’m just sitting here scratching my head wondering why the damn thing won't boot.
It boots straight into Windows just fine, but I’m staring at absolutely nothing—just a total black screen where the image should be.
I wouldn't exactly put my money on the drivers being reliable here...

What really drives me up the wall is being stuck using this integrated 256 MB graphics chip; it’s just painfully inadequate, so I actually had to go ahead and disable Aero in Windows just to make things somewhat tolerable. Honestly, if only Google...
I was typing away earlier and dealing with this annoying lag where my keystrokes were falling behind my fingers, but now that I've turned it off, everything seems to be running smoothly again.
I ran into this exact same headache with my previous motherboard; the integrated graphics just weren't up to the task of running Windows 7 properly, and once things started to go south...
So, I finally pulled the trigger on that Aero graphics card, and honestly, it’s a total beaut—it looks like it could fly. But of course, because my luck is exactly what you'd expect, it just won't work with this motherboard. Everything's plugged in, but absolutely nothing is happening. Just my luck, really.
I don't even have that old motherboard anymore—I finally decided to get rid of it, mostly because its maximum RAM capacity was capped at a measly 2 GB, which honestly made it little more than expensive junk.

I suppose I could hunt around for an AM2+ or AM3 motherboard if I really had to, though honestly, the thought of messing around with that old hardware just doesn't do much for me anymore.
I really should have known better than to go hunting for deals like this; I’ve already been burned a few times before, and honestly, I have a nagging feeling that this specific PCI Express slot is just going to end up causing me more grief.
It’s honestly driving me a little crazy at this point... I’ve reached that frustrating stage where I can barely launch any decent games anymore, unless they're just some really basic, low-spec stuff.
It feels like I'm staring at ancient history with this integrated 256 MB of video memory. 😵

I’ve also noticed that my 1080p HD movies are stuttering a little bit, which is honestly a bit frustrating because I was really hoping to rely on the integrated graphics for this; after all, the processor itself isn't exactly a weakling when it comes to handling HD video playback. 😉

I should probably mention that I’m definitely planning on saving some cash for a proper power supply for the GPU, just so nobody jumps to any wrong conclusions about my budget! But honestly, looking at the situation, I’ve got a nagging feeling that the PCI Express slot itself is just straight-up damaged. 😢
Who on earth knows who actually had their hands on this motherboard before me? Honestly, it’s anyone's guess at this point.

You might need to dive into the BIOS and disable the integrated graphics... basically just tell it to prioritize the dedicated card instead.

Look, I already mentioned that I tried doing that right off the bat... and honestly, it’s still not working the way it should.

Just to add a little more context here—when I swapped out my motherboard, I didn't bother reinstalling Windows. I know, I know, I've read everywhere that it's absolutely essential and technically the "right" way to do things, but I just
didn't get around to it since everything seemed to be functioning fine enough. At first, the USB ports were acting a bit wonky, but I managed to sort that out pretty quickly because my keyboard and mouse
weren't responding via USB, though it only took me about two minutes to fix. After I finished installing the drivers, everything was up and running, despite a few minor compatibility hiccups along the way..

So, I just couldn't bring myself to go through the whole hassle of a clean OS installation again..

I basically migrated from this old ASUS Motherboard https://www.asus.com/Motherboards/M2NMX_SE/ over to that ASRock board mentioned earlier..

Even if I were to try a fresh Windows install now, I highly doubt it would make a difference if the PCI Express slot is actually damaged. It’s clearly a hardware issue at this point -.-

I honestly can’t recall ever dealing with such catastrophic issues with any motherboard I've owned...
It feels like the whole thing is either completely dead or I'm just tripping over some driver mess because I haven't done a clean install yet.

So, I realize last night that my DVD drive isn't being recognized by Windows at all—not in Device Manager, nowhere. It doesn't even show up when I mash F11 during startup to try and boot from a disc; for instance, if I wanted to reinstall Windows, the option just isn't there. All I see in the boot menu are the hard drive and the floppy, which is just... what?
Which means I'm stuck in a spot where I can't even attempt a Windows installation via CD if I actually wanted to. -.-

The little light on the optical drive stays lit constantly. Once I get into Windows, the eject button becomes totally unresponsive. I can't even
get a disc into the tray; the only time the button actually works is right after I power on the PC, but once it hits that Windows welcome screen, the button stops working entirely.

It's bizarre... but honestly, what good would a disc do me if the system won't recognize it anywhere? And now I can't even eject a disc while I'm in Windows, so
I'm forced to just restart the whole machine.

I spent some time digging through Google for fixes when Windows fails to detect hardware, but nothing I found
is going to help me here. My issue is much more fundamental; the system isn't recognizing my PCI Express slots anywhere either. The PCI Express x16 slot only shows up in Everest, and
even then, the optical drive isn't detected there.

I've checked the cables for the optical drive and they seem fine, the power connection looks solid too, and I even swapped out the IDE cable, but still nothing. The DVD drive itself has to be functional,
that's a given, because why would it just quit on me right now? There's no way; it was working perfectly fine on my old board until yesterday.
In all the time I've spent putting together builds for myself and others, I don't think a single motherboard has ever given me this much grief.
Even a friend mentioned she wasn't entirely sure if it was in good shape to begin with; I probably shouldn't have picked it up, but now I'm just stuck dealing with this headache. Nobody gives you anything high-quality for free, after all. xD

At this point, I might just go buy a different one $67, something that fits this CPU, and call it a day. Because realistically, getting both the DVD drive and the PCI Express x16 port to work again seems like a lost cause.

So, a friend of mine mentioned she asked her boyfriend about this, and apparently, both the DVD-ROM and the PCI Express worked perfectly fine on this board—provided I just did a clean installation... but there's a catch, I can't quite
since my optical drive isn't cooperating, which means I'm stuck unable to boot from a CD. My only real option right now is booting via USB, but I don't actually have a thumb drive lying around somewhere. Is there any way I can somehow get
this optical drive to behave so I can finally get Windows installed?

I tried a fresh installation from the hard drive, but I ran into the exact same wall... I actually had to call up a buddy just to get him to copy the WLAN driver from a CD onto a thumb drive,
since there was no way for me to run it from a disc when my optical drive isn't responding, and I'd completely forgotten to move the setup files over to my D: partition before starting the install..
so, naturally, I spent a few hours totally disconnected from the internet, haha.

The motherboard just won't recognize the PCI Express x16 slot or the DVD ROM at all..

And following those registry fixes doesn't help my DVD drive situation either, mostly because I don't even see UpperFilters or LowerFilters listed, which implies I'm dealing with a different kind of headache altogether..

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

3. In the right pane, right-click UpperFilters, and then click Delete.

4. Click Yes to confirm the removal of the UpperFilters registry entry.

5. In the right pane, right-click LowerFilters, and then click Delete.

6. Click Yes to confirm the removal of the LowerFilters registry entry.

7. Exit Registry Editor, and then restart the computer.

A lot of people swear by this fix, but the consensus is that if you don't see those specific filter entries in your options, you're facing a much deeper issue.

Well, I certainly don't have them..

When both the PCI Express slot and the DVD ROM fail simultaneously, my first instinct was to blame a faulty power supply,
but I've already swapped it out for another 500W unit that I know works. Even though it's just some
cheap, off-brand unit, it should be plenty since my graphics card is a low-profile model that would run fine on even 350W—so I can rule out the PSU.

At this point, my money is on the motherboard itself being damaged; it’s been sitting unused for years, after all.

I've even tried swapping out two different IDE cables, but no luck there either.. It’s also been acting strange in Windows, where the DVD tray
will occasionally open and occasionally won't. That feels odd to me, because if the power supply is functioning correctly, the tray
should ideally pop open whenever it's prompted, right? Regardless of whether the system recognizes the drive, as long as
it has power, the mechanism should work. The only time it consistently behaves
is during the initial Windows boot sequence; once I'm actually in the OS, it becomes incredibly stubborn or just refuses to budge.
To make matters worse, the DVD drive isn't showing up in Device Manager, and it isn't even visible in the BIOS!!
On my previous motherboard, I never had a single issue with the optical drive or the PCI Express port.. everything worked perfectly.

I finally swapped in this http://www.asrock.com/mb/nvidia/n68c-s%20ucc/ motherboard, and honestly, everything is working perfectly right out of the gate—the graphics card is running fine and all the other components are behaving themselves. It turns out that previous board was just
completely dead..

is there any way to lock 😉

I've got the same motherboard now, so I was wondering if this reading from HWiNFO is actually normal. It's showing "MCP temperature 52°C"... pretty sure that's the chipset I added a fan to. Keep in mind that's the temp with the fan running, and my room is sitting at a sweltering 90°F right now.
