You must have a wire not plugged in properly. Tighten them up. If you went by the book everything should be ok.

I think it is problem in your BIOS settings. It is trying to detect a hardware that is not functioning. So try to correct the BIOS settings.

Uplug the hard drive cables, disk drives, cd, etc. Then power up and see if the mother board will run. Work from there.

yea this has happened to me before i think it has to do with your power supply, is this an older PC?  Pretty sure its the power supply shorting out a Lil and making it think its restarting

turn it back on... use the power button and it will "wake up" and turn back on.\n\nIf you are having problems, like it is getting stuck while waking up, turn it on, then hold down the power button until it turns back off again... and then turn on the computer (it will reboot).

Hopefully you have not shorted your motherboard. If you havn't then replacing the SMPS (power unit) will do. Otherwise, you are in for a lot of expense. Buying a new motherboard.

If nothing starts up then its a simple power problem and you should be able to start your system after installing a new Power Unit. However if you are able to start the system then try to getinto the BIOS and use the CD drive as a boot option. Try reinstalling Windows and this should work. \nIf you have important data, try taking your Harddrive to your friends or your other PC and then install this drive as a secondary drive on your friends PC. This will then allow you to recover your data and then you can even check if your drive is corrupted or only the Windows install.

so the power sign is green, but when you turn it on its just black? well all your screen is is a monitor connected to the cpu, so you might have power failure to the monitor, but not the cpu. its the same as when your tower is on but the screen is off with a desktop.

If you just installed it, then you have to go thru BIOS to enable it. If you had it in there and it quit, was it because you were inside working on something???....you may have loosened the cable to either the harddrive or motherboard. Is the power supply to the harddrive plugged in??\nIs the D drive a slave drive and is the jumper pin on the back of it set to Slave? Could be lots of things, you have to think about all the things that could have happened to it.

You mean everything? BIOS just woldn't come up? There is no way to fix that unless you send it in to the maker of the BIOS or where you bought your ocmptuer so they can fiz it.

check your power supply and makes sure it is connected correctly, and make sure the power supply isnt a dud

Does the thing power on?\nIf so then try replacing your graphics card with another AGP graphics card (just borrow one if you don’t have one spear).\nIf this works then it would seem that your graphics card is broken.\nIf this doesn’t work then try removing the AGP card and try adding a PCI card (again borrow one if you don’t have a spear).\nIf this fixes it then your AGP port is broken.\nIf not then you have probably fried your motherboard, this has happened to me before.\nJust replace the board.\n\n\n\n(EDIT)\n\nFollowing your recent additon to your question, I'm pritty sure that the motherboard is dead.. sorry.\n\n(EDIT2)\nafter removeing all the graphics cards does the onboard graphics work?\n\nalso, have u tried a diffent monitor??...

This can lead to two things.\n\n1.  Power supply is gone\n2.  BIOS is gone

If you have used a power suply tester and verified that that power supply in the current computer is OK, then unplug and replug in every connection to that motherboard. Try restarting the PC and see if the PC reboots up. If you have a second power supply then take the other one out and hook that one up. If you still cannot get the PC to start up or at least get the BIOS start up screen there is no sence testing the motherboard because my friend is fried. Consider replacing it.

all you have to do is reset the motherboard jumpers. take apart your computer and take out the jumpers for about 10 seconds and put them back in, the problem will be solved.
