Been on holiday, came back and PC would not start- dead - no lights. Whipped back off and afterf removing power plug from motherboard and then replacing it I got moving again. However, when I start up I get a checksum error and have to press f1 to start on default values. After this everything runs fine except the clock goes back to 2001.
Could the cmos battery be faulty? Don't think it would cause PC to be totally dead - would it?
Replaced CMOS battery and reset BIOS and all seems to be ok again. Think that what was happening was that after switching pc on it remained dead until a bit of charge built up in battery and then it booted giving the error message. By time I came to switch on following day then the battery was flat again and problem repeated.
Thanks for all suggestions
