Monitor colors are all wrong after PC changes

So, my PC has gone totally haywire. Everything on my monitor has this weird greenish tint, and any white background is covered in these nasty horizontal lines. Windows XP boots up just fine and loads the desktop, but the second I try to actually run any programs, they just crash—the whole system goes into standby and hits me with a black screen.
I've already tried booting from a backup system, but that didn't fix a thing.
The GPU is an Nvidia Geforce 7600 GS. Is it possible the card finally kicked the bucket?
What’s my move here? Does anyone know a reliable repair shop where I can get this fixed ASAP? I’m currently drowning in three different projects all hitting a massive deadline by the end of June...😠

Thanks in advance!

What else is in the build? And did you actually check the cable? Make sure it isn't half-unplugged or just trashed somewhere...

Check that shit and drop the specs here. Then we'll figure out what's next.

So, I pulled out that dual DVI graphics card—the one without the fan—gave it a good deep clean to get all the dust out, and popped it right back in.
No luck, though. Same exact story. 🤦

My setup: Intel D975XBX2, Intel i975x, Intel Core2Duo E6850 3000 MHz, Nvidia GeForce 7600 GS,

Oh, and get this: when I fired up Hiren's BootCD and ran the PC wizard to check my CPU temps and all that good stuff, everything was smooth sailing. I could click through Motherboard, RAM, you name it, and it worked fine. But the second I clicked on the GeForce video card option? Boom. Total system crash.

And here we go again... just a straight-up crash the moment I click that video card label...

I'm not really sure which cables you're talking about; this card doesn't even use any external power cables...

Alright, looks like the GPU is acting up. You checked Event Viewer yet? Any BSOD info? Might be worth running WhoCrashed to see what's actually going on...

That card is plugged into the monitor, via that cable.

Borrow a card or pick up a cheap one somewhere; yours looks like it finally kicked the bucket. Just don't go out and buy some high-end monster, or you might end up frying your power supply.

So, I spotted this one listing on Craigslist under the exact same name, but it actually has a fan, unlike mine, and looks completely different...

Here’s what I’m rocking

Can the one from the Craigslist ad actually fit in my rig? I’m asking because there seem to be a million versions of these Nvidia Geforce 7600 GS cards out there—they all look totally different and usually have some random prefix in front of the name.
Honestly, I'm pretty lost here...

William Richardson12 said:Alright, so if we're looking at a GPU issue, have you dug into the Event Viewer yet? Any specific Blue Screen of Death details? You might want to run WhoCrashed to see if it can make sense of the logs.

That graphics card has a cable running to the monitor—that specific cable.

Wait, you think it's the monitor cable? Come on now, a monitor cable isn't going to crash an entire PC, let alone stop programs from launching...

I mean, probably not. 🐔

So I gave WhoCrashed a shot, and it pointed the finger squarely at my Nvidia driver rather than any hardware issues..
Man, was I stoked for a second there... but that feeling didn't last long...
I tried grabbing the latest driver from the site, but the installation is a total disaster—the whole computer just freezes up mid-way and calls it quits..
Then it hit me: why not try an older driver? I found one that’s slightly newer than what I’m currently running, and hey, that actually worked and installed without a hitch..
But here's the kicker: when I tried to push through a proper update, absolutely nothing changed. It's like the update process is just spinning its wheels and doing zero actual work...
Now I'm totally stuck and honestly have no clue what my next move should be..

The only way to know for sure is to borrow someone else's basic GPU, or find some old working card and swap it in. That’s how you figure out if you're looking at a dead PSU, a fried card, or just a bad Motherboard...

Believe it or not...
I just finished restoring my system from a backup image, and wouldn't you know it—everything is running perfectly now...
Just to be clear, nothing about the actual "ghosting" process itself changed anything before; it’s working fine now...
🤦 🐔

Oh, I almost forgot the best part. While I was attempting to update some drivers, I eventually threw in the towel after a few failed tries. I hit "uninstall driver," but then panicked and clicked "cancel." Even though I supposedly canceled the action, the little pop-up window still insisted that changes would be applied upon restart... so, naturally, I rebooted. When the machine came back up, the desktop graphics were absolutely insane—everything was zoomed in like ten times over. Clearly, something had definitely shifted under the hood. So, I did another restart, booted into my backup software, restored the entire system from the previous image, and boom—it's back to normal. Like, wtf?!?

You wiped the driver, so that's why the graphics tanked... Not sure what happened with the ghosting thing, probably just some data refresh issue.

Just wanted to drop a quick note to say I finally cracked this thing, just in case anyone else ends up hitting this same wall...
Basically, even though I thought I was back in business after that last "fix," my PC kept blue-screening on me constantly while I was trying to actually get work done..
To top it all off, those weird lines started popping up on the screen again, though luckily they vanished as soon as they appeared..
It finally clicked that I should try installing the latest graphics driver right now, while the machine is actually behaving itself. Before this, every single time I attempted to update the drivers, the whole system would just tank mid-installation..
So, I went ahead and ran the installer, and now everything is running smooth as silk....🙏

So, how long has it actually been since my last post? Like, 45 minutes? Seriously, everything was running absolutely flawlessly right after that driver update...
But then, boom. My computer decided to go totally haywire again, throwing lines and weird green tints all over the screen. 😠

Swap out the GPU, it's the biggest variable left. There's a chance Windows just decides to go rogue and install some busted driver on its own...

William Richardson12 said:Swap out the GPU; that’s the biggest variable left on the table. There’s always that nagging possibility that Windows decided to go rogue and install a corrupted driver on its own.

The headache is I have no idea how to swap it without ordering something off eBay, and even then, I'm looking at at least a week of waiting...
I can't find a replacement anywhere locally, and honestly, since I'm already eyeing a brand-new rig, I'm really not feeling the urge to drop cash on an old graphics card...

It’s funny—when I was sitting around with nothing to do, this thing worked flawlessly. Now that life is hitting me with three times the workload, it decides to kick the bucket... just my luck.

Can I just throw any random card in there? I've got an old desktop lying around I could scavenge from. If I pull the Nvidia out and slap this old one in, will the BIOS or the OS throw a fit? I’m a little nervous about bricking something because I’m definitely not a pro at this stuff.

Of course you can. Any card with the right outputs and driver support for the OS will work. Since you mentioned Windows XP, you'll definitely find drivers floating around somewhere online...

That’s not gonna work because that card uses an AGP bus...

What I just don't get is that when I pull up the Device Manager, everything says my graphics card is running perfectly fine, and even that WhoCrashed tool is giving me a thumbs up on the GPU..
That’s what’s really tripping me up right now..

It’s probably not even the CPU itself. I’d bet money it’s some higher address in the VRAM. Once the memory gets filled up enough to hit that specific spot, everything just crashes...

Haha.. cheers👍
