During the past two weeks I've been having some problems with my computer. I have an Abit KT7A-RAID motherboard w/1.2ghz athlon chip, 1gig pc133 ram, 40+8.4gig hard drives, cdrw, cdrom, avance logic sound card, kingston 100mbit ethernet, and a geforce3 ti 500. I'm running Windows XP professional edition which was running smoothly, no crashes, no nothing for months now. But all of a sudden (no new hardware installed) everything keeps crashing. Whenever I ran a lot of applications it would crash (thought it was the memory). Whenever I tried transferring big files from one hard drive to the next it crashed (thought it was the hard drives). First the computer would just reset, then I got some blue screens saying: IRQL_NOT_LESS_OR_EQUAL. But today I got a blue screen talking about the nv4_disp.dll driver of my geforce 3. I turned the computer off and made sure everything was in tight, and turned on the computer. Nothing on the screen. Just says "make sure the signal cable is connected". I thought, great, probably the video card. So I swapped it for my old one and still no luck. I disconnected all the IDE devices, nothing. I removed the memory all but one chip, still no go. So I'm stumped as to what could be wrong. I'm thinking it might be a faulty 300W power supply (I'm hoping), or the motherboard, or something else. Any ideas as to what it could be? Or something I could do to further narrow down the problem? Most of the components are brand new other than the soundcard, hard drives, motherboard and power supply which I've had for 10months+. Any help would be appreciated. Thank you.
