Hello Guys! Having abit of a problem obviously. It all started a week ago when I noticed the cpu temp was abit too high. I opened it up and removed some layers of dust from the heatsink below the cpufan. Put all pieces together and reboot. Then I got a CMOS Checksum Error, so I went into BIOS and choosed Fail-Safe Settings, save and exit. No error msg now, but it just reboots everytime it gets to the winxp logo. How annoying! Anyway, I've tried a few things, but since I'm really no computerguru I didnt want to go too far myself. Here's a list of things I've tried and obviously didnt work. -Inserted Ultimate Boot CD, and checked the RAM's. -Changed the CMOS Battery. -Tried to reinstall windows, or atleast repair it, but it wouldnt let me, I got to the point when it checks the hardware then I received a blue Stop Error Screen the first try. Second try I got a black screen which told me something like this: "TRAP 00000006 = = = = EXC*PTION ===....." Thing is, that I can progress into windows, If I clear the CMOS with the jumper on my mobo and then press F1(continue) when booting. But that's the only way, I have to do that everytime I want to restart. The CMOS Checksum Error isnt constant, sometimes it says "CPU settings has been changed or cpu ratio..." I'm all out of clues here, anyone?
