dead cpu?
experiencing computer problems for some time without showing any output, after installing a new board it displayed a code indicating the CPU. upon inspection, you observed black marks on the contacts—this suggests the component may be damaged or failing.
The display/code was fully updated, but the RAM remains version 15 and isn’t functioning properly.
One of your RAM modules is placed in the incorrect slot—slot 4 instead of slot 3. Move the left stick to the right one. The red LED in your photos indicates the main BIOS is active. Would there be any changes if you switch to the backup BIOS? Have you reset the CMOS?
Yeah - I also spotted a lot of scratching or what seems like burn marks on the pads. When I looked at the photo, there were some caps on the lower right side indicating whether it's solder or a chip. If it's solder, it suggests the device has been fixed before. That doesn't necessarily mean it's bad, since I've done repairs myself to get a chip working again. Still... Clean those pads thoroughly and make sure they show more burn marks than scratches, which is something I've noticed before. You might try brasso or a little acetone to clean and polish the pads – this could help remove the spots, even if it doesn't guarantee a fix. Just be careful once you're done; ensure the chip is fully dry and free of any residue before testing. Overclocking often causes these burn marks, but high CPU voltage for any reason can too.
Everything is functioning properly now, though a few pins on the old motherboard appear bent, which doesn’t make sense since it hasn’t been handled.
Save this image next time you change or install the CPU and it doesn't boot. The issue is the pins are misaligned, not bent. They've shifted sideways which can make the machine appear non-functional. The best fix is to take out the chip, realign those pins, and retry. If everything functions properly, avoid removing the CPU unless you have no other option. I found this problem with my Z77 OCF—after fixing the alignment, it worked, but now I keep watching one pin closely because it tends to shift like in the picture. Refer to this image if it starts acting up after a CPU swap or replacement.
I'm puzzled about the CPU not being used after installation. I only faced issues when I unplugged the PC and relocated it.
You might have unintentionally pressed it too hard (maybe dropped it?), which could slightly disturb the chip and/or pins, making it difficult for them to shift without issues. Just like with my own setup—use a magnifying visor with a light and a small tool like a tiny screwdriver or even a toothpick. A toothpick is handy because you can adjust it easily if needed. Proceed slowly and carefully; be cautious of pins moving suddenly when they weren’t moving before, due to resistance. When they do shift, it happens abruptly, so be prepared for bent pins. Even if one shifts sideways, it’s still possible but not ideal. Work at your own pace—there’s plenty of time, no rush.
