I have an MSI K8N Neo2 Platinum motherboard with an Athlon 64 3500+ CPU. Recently my computer started becoming unstable and crashing, then I ran memtest86+ and it failed repeatedly at one specific memory location. I RMAed my motherboard, and just got it back. They didn't fix the problem at all, it crashed just as often, but I got the idea to try moving my two sticks of RAM to other slots (I have 2x512MB DDR400 in dual channel) and everything worked fine. Except for one thing...
I have a dual boot with Windows XP and Ubuntu Linux. When I get to the boot loader, Windows is the default, and it will simply ignore my keyboard input, so I can't boot into Linux. This didn't happen before I RMAed the motherboard. When I try to change things in my BIOS, before the boot loader is loaded, my keyboard works fine. After leaving the boot loader, everything works fine. It is only when selecting my OS that the problem exists. However, when I tried using a friend's keyboard, it worked perfectly when I connected his keyboard to PS/2 (I haven't tried USB on his computer). My keyboard mysteriously doesn't work at all when connected to PS/2 - actually, I get an error message before getting to the boot loader saying there's no keyboard attached, but this problem didn't exist before getting the motherboard back from the RMA. When connected to USB my keyboard is still fine though. I don't have any clue what could be the problem here. I've tried updating GRUB, but it didn't change anything.
Any ideas what's wrong? Also, any advice on what I should do about the motherboard, since they didn't really fix it, but I don't want to go another month without my computer while going through the RMA process again, with no guarantee that they'll actually fix the problem.
