The weirdest things have been happening. I cleaned every component of my computer and re-seated the connections. I formatted and freshly installed Windows XP. Sometimes I get into the following cycle: 1. Computer turns on for the first time 2. Goes to black screen straight away 3. Only way to fix the problem is to reset the CMOS jumper on the back 4. Flip the CMOS 5. Reboot -- runs great. 6. Restart or hard power off 7. Black screens right away 8. Must reset the CMOS jumper to get the screen to load There have been a couple weeks where I had to go through this process every time I rebooted my computer. Currently I'm having this problem: 1. Computer turns on 2. Loads windows 3. Black screens after Windows I turn the computer off, boot into BIOS, change voltages and settings, and SOMETIMES I will get the system to boot into Windows. It will run beautifully for a few days! And then... black screens. Sometimes the board black screens before POST, sometimes the screen freezes during the Windows loading screen, sometimes it black screens after Windows loads, sometimes it auto-restarts after Windows loads, sometimes it auto restarts before POST screen. I get a lot of C1 errors, which are memory errors. However, I ran my RAM through Memtest86+ for 11.5 hours and it had 0 errors. The system did not crash. The system is stable when installing Windows XP from the CD. It has never crashed. And oddly enough, every time I do a fresh install, I can boot into the OS just fine! It'll run good for a few hours or days, and then more black screens. It's like hardware failure because sometimes the board doesn't post or freezes during loading... And it's like software conflict because reformatting and reinstalling Windows XP almost always allows me to boot into the OS at least a few times before more black screens. We checked the PS. It is delivering the correct 5v and 12v when under load. CPU problem? Motherboard problem? Motheboard/RAM incompatibility? Help! Intel Q6600 Abit IP35 Pro Patriot Extreme Performance DDR2 800 RAM (2 sets of 2x1 GB) Seagate 1000W Power Supply EVGA GTS 8800 I've tried all sorts of voltages.
I would go into the bios and set the bios to default or optimize settings first, then try and go into SAFE mode to see how it runs in there.. Have you scanned for a Virus yet ? This Problem could be a number of things, You do not have to move the jumpers on the board, just remove the bio's battery for 10 minutes.. It sounds like you will have to check each and every hardware piece to narrow down the problem...
