Hi, guys. I need some help, and I'm hoping someone has insight into this problem. Recently, I flashed the BIOS on my ABIT KT7A-RAID board. It went through just fine, so when the system restarted, I went into the BIOS to switch the boot sequence from the Floppy back to HDD-0. When I exited BIOS, my monitor went into "no signal" mode and the system didn't boot. I heard the fans spin, and the HD start to rev up, but that was it.
I figured it was a bad motherboard, and wanted to upgrade my system anyway, so I bought an MSI Ultra ARU i845 mobo, P4-2.0A processor and 2 256 MB Micron PC2100 chips. They arrived, and I put them into my box. The system started up, I installed Windows XP, and noted that it was only registering 256 MB of RAM. Not a tragedy, so I shut down the system, switched one of the DIMMS out to another DIMM socket, and rebooted. Everything was fine, 512 MB. Great. So at worst, one of the 3 sockets was bad. After I started reinstalling apps, some required reboot. My first reboot resulted in the original problem, where the monitor would lose signal, and the system wouldn't boot. I hit the reset button twice, and finally the system powered up. After Windows started, I shut it down and started playing with the RAM to see if I had a bad DIMM or if the motherboard was the problem. Sometimes, I'd power up the system with only one DIMM in one of the 3 sockets, and it wouldn't start, but I finally thought I found the one good DIMM and socket I could rely on. Just to test, I played a full game of NHL 2002, and everythign was fine. I defragged my app partition overnight and wanted to see if everything was copacetic in the A.M. It was. So, just to see, I swapped out the DIMM with the one I thought was bad, placing it in the socket I thought was good. No start. Fine. I put the good DIMM back in that socket. No start. Uh-oh.
So... now what? Do you think it's the motherboard? Could it be the power supply, even? I'm pretty stumped. All I know is my vid card works, so that's not the problem. Any help would be appreciated, because I have to return defective parts post-haste to get my money back or a free replacement!
Thanks in advance!
