What led up to the problem - was there new sw, hw, a virus, an error? What is different since the last time the system booted properly?

Also - can you hear the fan running? Does the HD light flash? Have you tried a different video card?

That's the kind of information you need to provide.

all fans are running, i have tried to change the hard disk believing it might have a virus or hard disk defect,  i have tried to pull out the cpu, check and install / insert it again, check the battery on the mother board , but still the problem exist. No post beep, no display and the computer does nothing. any other idea! thank you.

If you have a prebuilt computer (e.g. A Dell), what model do you have?

If you build it yourself, what motherboard do you have?


We need to know this so we can try reseting the CMOS.

No we don't. The cmos is reset the same way on every system. But why do you want to reset the cmos?

Have you tried a different display just to make sure that's not the problem?
