Hey, I have a quick question that I am sure there is a simple solution. My question is that when I boot up Windows XP Home Edition SP2, it BSODs and restarts again with the BIOS screen and then gives me the black "windows did not start correctly" screen with the options Start Windows Normally or use Last Good Configuration (or something like that). Starting normally will only induce the same problem again while using the last good configuration will allow me to boot to Windows successfully. I'm sure this is a quick fix, but I can't think of the solution right now. Steps that I took to "try" to fix the problem: -Registry Mechanic full scan -run anti-virus and anti-spyware programs System build: totally custom built AMD Athlon64 3700+ San Fransisco w/ 5500 rpm heatsink ASUS A8N Premium SLi eVGA GeForce 8800 GTS + ATi Sapphire Radeon X850 XT (yes, in the same computer; nVidia TV out stinks, but ATi rocks with it!!!) 1 GB Corsair RAM 4x HDDs (one 160GB, three 320GB; total 1.12TB) 2x Cooler Master 6 HDD coolers (primary usage drives) ASUS QuieTrack CD Drive NEC DVD Burner/Drive D-Link Wireless Networking Chip (for network surfing) 2x PSU's (primary 430W psu, secondary 350W psu modded) Now, before your get your panties in a bunch, I have a new PSU (600W) coming in tomorrow with dual 12V rails for both video cards. Just recently (when the problems started), I had my primary 430W PSU start acting strangely when it would shut off suddenly at night and then start up again suddenly. I figured it was just old age (had it 2.5 years) and ordered a new one. Then the booting problems happened. I am somewhat sure that it could be a PSU problem, but I though I would ask some experts to see what they say! Thanks in advance!
