Computer won't boot, displays checksum error

[stirredo]

My PC won't boot on being switched on......it won't display anything on monitor and the LEDs on keyboard won't blink(they normally blink once on being switched on). Sometimes when i am lucky it would start(with a checksum error) when i press the reset button after keeping the cPU switched on for like 4-6 hrs.

I have already replaced the mobo battery with new one and i am still facing the problem.

Any idea how to fix it?

What is your computer? Operating System, make & model number.... It may be a dieing hard drive or bad memory

Thanks for replying.

Like I said I am able to run it after like keeping the cpu powered on and then pressing the reset button after 4-5 hours. I am the currently using the pc with reset trick. It can't be dying hd. I also tried refitting the memory.


I am running windows xp on intel 2140, 2X512 ddr2 533mhz with seagate barracuda 250 gbs. mobo is Gigabyte GA-VM800PMC.
