bios checksum error

[abhinandh]

i get this error when i start my computer.cmos battery is not faulty.date and time are correct.using an intel 845 mobo.

check your motherboard manual as the jumpers for clearing the data seems to be short.. this happens in this case only..

Power Down Your Comp completly.
Locate The big sized battery ( ie CMOS battery) on the motherboard.
Remove the battery & after about a minute later put it back on.
This will put your mobos settings to default.
Your problem should be solved. If not try to replace the battery.
They will cost you Rs. 8-10.

i guess you didnt read the question fully ? he says battery is ok.. and date and time are also ok.. ? that means the jumper is set wrong !

I have faced this issue with my mercury 845 mobo. Just re-sit your ram and gfx cards properly & clear the cmos setting by jumper or by removing cmos battery & put it back again. Yours problem should be solved
