I just put together a new PC. I have had more trouble with this one than I have had with any other. Anyway I get everything to working and running ok. I turn it off and come back to it the next day. I turn it on and get a vocal "CPU Error" turn it off and back on get it again. I turn off the power supply and turn it back on. It starts up and gives me a "Cmos Checksum Error defaults loaded" on the start up screen. I go into the BOIS reset Defaults. "This is what the manufactures told me to do" Restart it everything is cool. The problem is every morning I turn it on I go threw this same thing over and over every day. "CPU Error" than turn it off "CMOS Checksum Error" Reset it the defaults... bla bla bla Other than this it runs fine, doesn't over heat, or give me this when I turn it off during the day. I have cleared the Cmos, reset the chip, and Flashed the BIOS. It still does this. Any idea? System spec....P4 2.8 800/FSB.....Aopen AX4C-Max MB... DDR 512MB...NV Geforce 4 Ti 4600....
