I have a k7n2 delta with a 1.2 ghz processor, 1 GB of RAM, and an 80 GB HD. This computer has faithfully worked for around 5 years. The problem is that it sits on carpet and gets a lot of dust inside. Recently I was considering upgrading the RAM, and I was moving my 1 GB stick and my 512 MB stick between the three memory sockets because the memory didnt seem to be working correctly. During all of this when i tried to turn my computer back on(RAM was installed) I got a blank screen. I kept working with the RAM though, thinking that the two might be related. The next time i turned the computer on it began to smoke, and after turning it off I found that the second memory socket and 512MB stick had been burning presumably because of a dust buildup. Unperturbed, I cleaned out the soot and all the dust and left the 1 GB stick of RAM in the 1st working slot, and I got the video to work by removing the bios battery and plugging it back in. Windows installed fine, but when I restarted the computer, the bios loaded and proceeded to where windows would have been but it was just a blank screen. I restarted the computer to find the "windows did not correctly start" screen, and so i saw that windows was not going past MUP.sys. I tried loading the windows install cd to do a repair install, but after the cd started it would hang at the "starting windows..." message. Likewise, live linux cds would give me a kernel panic. I opened up the computer and I unplugged the bios battery and put it back in, and everything worked again. But then Windows randomly restarted today, and it gave me the same thing, and so i did the same process again, and it worked again until I got a BSOD that said "DRIVER_IRQ_NOT_LESS_OR_EQUAL" and the same thing happened again when i restarted. Now however, when i try to enter Windows safe mode, it stalls at hotcore3.sys instead of mup.sys. It seems obvious to me that this cannot be a software issue, because it happens to both linux and windows and cds cant start at boot. Im guessing that either the RAM is bad or the BIOS is bad since removing the battery always fixes it. I have attempted the restore defaults within the bios manually at startup, but nothing seems to fix the problem besides physically removing the battery. Any ideas?
