I've just recently bought computer parts to build my very first computer. Here are the primary parts I've bought: -ASUS "A7N8X-E Deluxe" nForce2 Ultra 400 Chipset Motherboard for AMD Socket A CPU -AMD Athlon XP 3200+ "Barton", 400MHz FSB, 512K Cache Processor -XFX nVIDIA GeForce 6600GT Video Card, 128MB GDDR3, 128-Bit, Dual DVI, AGP 8X, Model "PVT43AND" -Maxtor Ultra Series Kit 120GB 7200RPM IDE Hard Drive, Model L01P120 -Kingston 184 Pin 512MB DDR PC-3200 (Two sticks) -Sony Internal 16X DVD+/-RW / Double Layer Drive Black, Model DW-D22A-B2 So, upon installing Windows XP Pro SP2 Integrated, everything in the install and before goes smoothly. When coming into Windows for the first time, things seem okay. But there are random restarts all the time happening in Windows. The restarts never seem to happen consistently either. It could happen every few minutes or so, or it may not restart for an hour or so. I've gotten so many random error screens(the blue screens) that I have no clue what is wrong. I've been talking to someone I know that knows more about this in detail, but they're lost as to what could be wrong. Maybe it's some weird compatibility issue. I would like for someone to look at what I have here, and see if there's any issue as to something not working with another device. The errors I get when I come back into Windows state that it could be a Graphics Device Error, or that the CPU has reported a hardware error, or that there's just a hardware error, period. Sometimes the error says there's a RAM issue. I really have no clue what could be going on. My friend has helped me over the internet with what to try to get it to not restart randomly anymore, but things have not seemed to help. I've tried using an old IBM 20GB HDD to install an OS on since it supports FAT32 and whatnot, and yet with that hdd, there are still random restarts. Something is causing the restarts, and with those restarts, it corrupts my Windows XP. Can't seem to find anything that will fix this completely. Thanks for reading.
