I dont know if its bad luck or what but the past 3 mother boards had problems and I had to send them all back. This is my 4th and now when ever I turn on the darn thing is comes up with "CMOS checksum error". This is really agrivating me I did a cmos reset with the jumpers, still didnt work. The mother board bios do reset (i think) but it still comes up with that error. The only time where I can skip that error is when I go into the bios and hit the "Load Fail-Safe Defaults" and "Load Optimized Defaults". But then still I will try to run xp and it just restarts at the xp loading screen. Can someone help me please I feel like throwing my machine off a cliff. My set up is- ABIT GD8 Socket T (LGA 775) Intel 915P ATX Intel Motherboard Intel Pentium 4 630 Prescott 800MHz FSB 2MB L2 Cache LGA 775 EM64T Processor Thermaltake TR2 W0070 ATX 430W Power Supply 115/230 V Radeon X800GTO 256MB 256-bit GDDR3 VIVO PCI Express x16 Video Card Do I need to update the BIOS maybe? Thats my only guess.
