I had to google 'load shading' as I'd never heard of it. I guess it's when officials capriciously shut off the power, often with no notice. I'd make sure I was using a UPS if I lived where that could happen.

Anyway, your problem is with the PSU, motherboard, cpu or a combination of those. The cdrom not opening may not be significant. It has an initialization procedure it goes through when it powers up and may not respond to the button right away.

I'd swap out the power supply temporarily with a known working one and see if it powers up then. If not you've probably got a problem with the motherboard.

You have not suggest any thing. I already knew the info that u told me. Tell me how I reset it ,if u can. The Power is on Power Supply is as usual fans are working properly but there is no display and no beed while CD Rom's Ligh is blinking but not opening the CD Rom. And when I press the Power button after turned on it is not working as well, whil befoer it works.

Most likely you have a hardware failure in the PSU, motherboard, cpu or a combination of those three so no reset is possible.

However perhaps one of the peripherial items has failed--one of the plug-in cards or one of the drives. Temporarily remove all the cards except video and disconnect all the drives. Then boot up and see if you get a posting screen. Or, if you were inside the case fiddling around maybe it happened then. I just assumed that it was due to the power failure since that's the only thing you mentioned.

If you get a posting screen then one of the items you removed is the cause. If you don't get a posting screen then you're back to the PSU, motherboard or cpu. Most of the time the PSU is easiest to test by swapping it with another one.

If a different power supply doesn't work then you probably should look to replace the motherboard. If so, post back the model number and we can look around for a replacement. Replacing a P-II/III motherboard shouldn't be expensive.
