|First, some background info on my problem (sorry, it's a long read. Skip to the bottom if you want, I made a summary there):|
All my problems started a few days ago, the day after I upgraded my video card. I noticed my computer was acting weird... the entire system would just lock up for a second, or maybe a bit less, at random intervals. This would also happen to me when I was playing CoD4 on my new video card: the game would freeze during gameplay, but even when I was still in the menus, the cursor would not move at all sometimes.
The morning after this, I went to turn on my computer. I turned the switch on the power supply to ON, and pressed the power button. The system beeped once (it usually beeps twice at startup. according to the motherboard manual, one beep means it passed POST.) I'd been wanting to upgrade the hard drive for a while, and assuming that my hard drive was causing my problems from the night before, I swapped it out for a new
WD drive, 640GB. (the old one was around 120GB)
After doing this, I get no beeps at all, meaning it doesn't even pass POST now. I disconnected the card reader in the front, which had given me problems before... no change. I took the memory out, and I got beeps every other second when I started up the computer, which means DRAM not detected or missing.
So, I'm guessing the memory is the problem, since I got a beep code when I took it out, but nothing at all when I put it back in.
In summary: Had problems with computer one night, system would freeze for about a second at random intervals. Next morning, the computer did not start up. BIOS did not
load, but it still passed POST. Replaced HDD, doesn't even pass POST now. Still no BIOS. Guessing memory (RAM) might be the problem (see the two paragraphs above this one.)
So, I'm guessing my memory is the problem now, but I'm thinking maybe the motherboard doesn't like the fact that I replaced a 120GB hard drive with a much bigger one (640GB.)
Motherboard model: K8VGA-M made by Biostar. ~3 1/2 years old
