Can't get into bios. 'puter will start up... Hang at "hit del to enter setup"....then I get 2 short beeps pause and 1 beep. It show CMOS checksum error and CMOS Display error. I then get .....Press F1 to enter set up .......Press F2 to continue. have check AMI and it says it's a memory problem. Have tried moving CMOS jumper....Have tried removing CMSO battery(overnight).... It comes up the same way...Not sure what I'm doing.. I don't know what the psu is... no lable where it can be read... Just put in an FIC SD11 mobo. Have checked all cables, and memory sticks. Have tried with only HD and Video card... keyboard isn't reconized. When I try to tap del or F1..F2 nothing happens. Lights on drives light up... except small floppy. Computer was working before changing mobo. :giddy: Thank you for any help you can give or direct me in any direction.
