So, earlier today, I figured it was time to reformat my computer. It was running quite slowly, and there was a lot of background apps I didn't particularly like sorting through, so I thought it was time for a cleanup. At this point, after my backups were done, the computer started freezing randomly. That is, the screen completely froze and the keyboard and mouse were unresponsive.
I figured, yet another reason for a wipe. So, I wipe the harddrive from the Windows 7 boot setup, and start installing, but just after the first restart, it freezes again during windows load. I give it an hour, but it doesn't resume, so I restart. Problem is, it still freezes after a minute or so, whether I'm in the windows setup or in BIOS. Since starting, I have recieved three kinds of POST signals. Firstly, a short, high-frequency beep. After a few more tries, it stopped being short and continued beeping until I shut the computer off. These, I'm told, supposedly say that my RAM is no good. In response, I took out and tested the memory sticks individually, and while there were no more beeps, neither did it fix the freezing problem.
After I added both RAM sticks once more, there was a brief couple of tries where I recieved the POST signal for missing GPU, though it is likely that I had only bumped it while placing the ram, since it stopped once I pressed it properly in place. I tried running memtest, but that freezes after a few minutes as well. Latest thing that happened was a continous repeating letter combination across the screen, like so:
So, here I stand, at a loss of what I should do next to isolate the problem. My specs are:
Asus M2N68 plus
AMD Athlon 64x2 dual core 5600+, 2800MHz.
51 degrees C CPU temp
NVidia 8800 GT
