Hi, i got a problem with my computer, its custom built with Radeon 3870, AMD 5400+ Black Edition cpu, 4 gig ram and a Silver Power 600 watts psu. I built this computer in February this year and had it running until now. I was going to a friend on a lan but when i got there and tried to turn it on it just goes to a screen that says: My bios name and the name of the motherboard which is A-780GM-A, below that my cpu info Press Del to run Setup which aint working for some reason Press F11 for BBS Popup Then it says its detecting 2 sata inputs, that would be my DvD and hard disc Below this crap it says CMOS Battery Low CMOS Date & Time not set BUT i have bought 2 new batteries but i get the same message. I can enter BIOS by pressing F1 but that dosn't help me much. I have tried to reset it to default settings and restarting but it just goes to the same place. The computer worked like a dream before i plugged it in at my friends house, I cant understand what has gone wrong. I have also tried to just run the computer with my CPU, one stick of ram and videocard, but i get the same message Any help?
