"CheckSum BIOS Error- Insert System Disk or press Enter. Nothing happened after pressing Enter. So I shut down the machine and started again. This time nothing happened, no initial BIOS screen, only a long beep which stopped, and the floppy light went on for 3 seconds and then went off. Nothing proceeded. Only the fan was running. I started again and again but it was giving the same long beep. Finally I shut it down. The next day when I tried again, this time it started and went on fine for 2-3 days, when it happened once again. This time I went to a hardware technician, who took out every thing checked it and told me that its a BIOS problem which needs to be reprogrammed and then he reprogrammed it. Again it worked fine for a day and then again the same problem started. This time when I tried again after a day it started normally. every connection and jumpers inside were checked, found tight, nothing loose but still every now and then it gives the same problem.
Cant figure it out whats wrong with BIOS. Why it doesnt work and then suddenly work after a day or two.???
