First try a different monitor which you know is in working order.
If still no signal, try a different graphics card in a spare PCI slot.

"I took battery out for few day"

A few days? It only takes a few seconds to reset the BIOS. If you have installed a video card, switch the monitor cable to the onboard video, then see if you get a display.

When you removed the cmos battery did you have the power cord disconnected? For future reference there probably was a 'clear cmos' jumper on the motherboard you could have used.

The fact it kinda worked before you were inside the case and didn't work after may indicate something happened then--you zapped it, jostled something loose or didn't reconnect everything correctly.

Another thing I often ask because it happened to me and your symptoms are similar, if your PSU has a 115/230 voltage switch make sure it's in the correct position. DON'T GUESS. And if you do need to change it make sure the power cord is disconnected when you do.

The problem is unlikely to be with your cmos. The cmos is really just the parts of the bios you can alter--time, date, drives, some hardware addresses, etc. Even if you clear the cmos with the jumper or by removing the battery all you've done is change those settings back to default.

If everything inside checks out OK--and it's not some oddball thing like a PSU voltage switch---I'd still guess the problem is with the power supply. Edit Prior to it not working at all, you said it shut off just as windows started to load. That's when the hard drive probably works the hardest and maybe a weak power supply will have a problem at that point.

Well, one other thing. When you said the 'windows screen flashes' I assume you meant the normal windows logos and messages as it progressed to the desktop but could it have shown an error message and then shut down?

Hi Richie, (as partially suggested above) I would:-

a) with the power off, disconnect/reconnect the monitor interface cable (possibly both ends) and power cable.

b) if no joy, try another monitor.

c) please advise, what if anything appears on the monitor when it flashes.

d) if 'No SIgnal' is appearing on the monitor this suggest it is ok and there is a simple interface cable connection problem. Also there may be a strap on the mobo for off or onboard graphics.

Hi Phil, before trying another card, I would have advised, if present, reseat the graphics card (by removing/replacing 2 or 3 times) in its own slot, next try in another slot.
However in this instance the op advises the problem still occurs when using onboard graphics. Regards - Mike.

Good Luck - Keep us posted.
