Default computer won't boot after CMOS reset

OK I was working on the following error
Quote:
Ok everything worked fine this afternoon. Turned machine off and went away and come back and now I can't get any thing on the screen.

Have an 8800gt that has worked fine for months.

Removed it, replaced it etc etc etc
Tried to use old 7600 GS and nothing there either.

So tried to use built in graphics and again nothing.

It seems that there is something coming from the computer because monitor goes out of sleep mode when the computer is turned on, but i can't get anything on the screen at all.

Tried to launch in safe mode, heard a few beeps, but can't see anything to know if it is doing what I want.

Any ideas?

PS I know the OS and computer work fine because I here the 'pop' of my virus program telling my subscription has run out.
I reset the CMOS to see if that helped and when I try to restart the computer no longer boots.
It does beep, but nothing afterwards.

Any thoughts?

Since you are having the same problem with three different video cards, I would suspect the problem is with the monitor. Do you have a different monitor that you can test on this computer? Or a different computer that you can test this monitor on?

Disconnect screen and remove all parts but the cpu. Reset BIOS properly as in my stock answer below. Power it on it should long beep. (if not faulty board/PSU/CPU in that order ? test PSU with voltmeter, cpu in another system, board may short so try it out of the case before RMAing). If beeps as expected do as described.

Stock answer: Disconnect power. Reseat CPU and power cables, remove everything else. Check jumpers. Connect only power button. Remove 3V battery and short-circuit the contacts. Press power button. Replace battery. Add one stick of working memory into 1st slot (closest to the CPU). Install graphics/use integrated (if any). Try to boot.

I tried what you said.

I still get the normal everything is fine beep, but then nothing else happens.

Have a new Dell on the way, when it gets here I may try the PSU in this machine to see if that is my problem.

Otherwise I guess I will look for a cheap MOBO with a good return policy

Hi ProfJohn,

The reason Windows won't load is because when the CMOS is cleared, you are prompted next bootup with something like this:

[F1] for setup
[F2] to load default settings

Of course, since your screen is blank you don't get to see this.
So press F2 and most likely it will boot up and you will be left with your original problem - blank screen.

You never said if you swapped the monitor as Fardringle suggested. That should have been the next step. Anyone you know have a desktop or laptop you can try the monitor with?
Or hookup your pc to their monitor?
