I purchased a month ago a motherboard (LGA 1156 - Gigabyte P55A-UD6) at about 328USD. All worked fine until yesterday, when I saw I mounted the CPU fan (Thermaltake Frio - a monster of 1.5kg weight) in the opposite way. I decided to put it in the "normal" position. Problem is, when I had to unscrew one screw from the back of the motherboard, the screwdriver slipped and I made a scratch on it (it doesn't seem very deep to me, BUT it hit most traces near the CPU / Memory).
All that to say: system boots up without any problems (both windows 7 and Gentoo GNU/Linux) (so where's the problem you'd say, right ?). Worried about the damage, I did a memtest86 test and - surprise - Some 40'000+ errors went up to the surface. I already had problems with memory (one defected module I had to change 1 week ago) and tested the memory was fine. So I think I hit the traces from the cpu to the RAM. Tried with only 2 modules instead of 4 but same errors. It's not the memory ... it's the damaged motherboard. Now ... that motherboard costed a lot of bucks to me ... I don't know if I should attempt a repair with some solder I read on superuser.com (another thread) or leave things as they are now. I remember with the damaged RAM the system would hang or give random segmentation faults. Should I try to stress it with prime65 to see the "real" impact of the damage ?
Thank you very much in advance !
