Michael Jackson10 said:Alright, let's assume you've already done the physical check on the RAM and ran some tests like I suggested earlier. Just one super basic question though: since you went ahead and did a Reset BIOS, did you actually hit "Load Setup Defaults" once you were back in the UEFI?
Also, I'm a little confused here—how did you even figure out the drives were messed up if the PC is totally bricked? Did you check them on another machine? Or maybe tried wiping them and re-initializing?
I feel like saying you "tried everything under the sun" doesn't really give us the full picture of what you've actually attempted. No offense intended, but we deal with all kinds of users here; for some, a simple fix is second nature, while for others, it's basically open-heart surgery...
Here is the situation (pardon the rushed posts—work is a madhouse right now and I am absolutely exhausted):
Earlier this spring, my hard drive died. Since money was tight, the PC sat idle until three days ago. I picked up a new drive at Best Buy a few days back, hooked it up, and installed Windows 10 without any issues. That's when I noticed in This PC that while 4GB of RAM is installed, only 2GB is usable. After digging through some hardware forums, I realized quite a few people with this specific motherboard (an ASUS model) hit similar walls due to supposedly incompatible memory—which is bizarre, because I never had an issue with it before.
Reading further, I saw mentions of CPU issues caused by bent pins, but that's impossible; the last time the processor was touched was eighteen months ago during a repaste, and everything worked perfectly after that. Then, I tried a Reset BIOS by pulling the battery for a few seconds, and that triggered this strange boot loop—the fans spin to max, everything shuts down after five seconds, then it boots normally. Because of that weird startup, I jump straight into the UEFI and select "Load Setup Defaults," but it does nothing; after a restart, the same thing happens. Regardless, I let the computer finish booting, enter Windows, and suddenly the usable memory dropped from 2GB to 1.99GB. Another suggested fix was flashing the UEFI, which I did (moving from F3 to F12), followed by what you told me: "Load Setup Defaults." Suddenly, This PC and Task Manager showed 3.25GB usable. I rebooted again, and the system finally recognized the memory properly (though that odd boot behavior persisted after every reset). Once I installed the GPU drivers and antivirus, a UEFI checksum error popped up, saying it was retrieving a recovery source from the HPA. From there, it was total chaos. Sometimes, pressing the power button just starts a continuous loop of turning on and off, and on the rare occasions it actually stays on, I get a disk read error. I took the drives over to my brother's place to see if they survived those violent power cycles, and there I found the capacity listed as only 32MB—formatting won't touch it. Apparently, this happens with certain ASUS and Gigabyte boards when the UEFI fails...
