My specs: ABIT KU8 mobo AMD Athlon 64 3000+ w/ CoolerMaster HS/F 2 Gb Corsair XMS, PC3200 80 Gb Western Dig. HD (master) + 40 Gb Western Dig. HD (slave) ATI Radeon 9800XT XP Pro 420 watt power supply It started a couple weeks ago with random blue screens saying "MACHINE_CHECK_EXCEPTION", and they would come frequently. After my computer was off and I would try to boot it, it would say something about having to connect the power cable for the 9800XT. Of course it already WAS connected but whenever I reconnected it, the computer would boot fine. I tried removing the 40 Gb which I had recently installed because maybe it was sucking too much power, but it still would bsod on me. Then for a while it stopped. Now today, I have had 3 bsods, and the third one was fatal. First time it happened I rebooted normally, but when Windows came up, it would randomly freeze for a bit, and then unfreeze for a bit, freeze for a bit, then unfreeze, and then freeze, and blue screen. I found out that whenever it froze for that short amount of time any sound I had playing would be repeated (like someone stuttering really really fast and then continuing). After 1 more restart, it did it again. And when I tried to boot, it said on my monitor, "Please check signal cable". Meaning it wasn't getting anything from my video card. I have tried several replacements- Took out the 40 Gb again. Replaced the RAM with my old 512 mb Corsair. Replaced the Power Supply with a 350 watt. Now I can't replace the 9800XT because I don't have a spare, and the KU8 doesn't have a built in video connector. Is the video card the problem? Because I've had it pretty much since it was released (Paid $479 for it!), and haven't had any problems. Please try to help me!
