Nothing display on my monitor


I have a Gateway GT5058 Desktop PC which was working fine until the other day when by accident I pressed the battery backup's on/off button and turned everything off. When I turned everything back on, my monitor showed a "No Signal Found" error. The hard drive made the usual noises when I turn it on and then the noises stops. I think maybe because the OS is prompting for the password??? I always use a password to secure my PC.

I tested the monitor on another computer and it works fine so it is not the culprit. I thought the Radeon HD 4350 graphic card went caput and removed it and installed in another computer and it works fine. I even tried using my PC's integrated graphic connection and still I get the same error. So again the culprit is evading me. I'm suspecting the Bios is the culprit but I'm not sure. So what could be wrong?

Please HELP! I need my PC really badly or I die!!!! Well not that bad but still I need to get it to work asap. Thanks!!! Wink

Do you get the splash screen . . .

on boot up? If so can you start in Safe Mode.

Is your PC available to everyone? If not, why a password? You can now see the problem.

Since you didn't tell us the OS . . .

Thanks Coryphaeus for your help. Maybe I didn't explain myself well. Let's put the password thing aside since it is not relevant to the problem I'm having.

When I turn on my PC, the monitor's power light goes green for a second then shows the "No Signal..." error momentarily and finally the screen goes black and the power light goes orange. The PC's power button light lit up and the hard drive makes the usual sounds the same way it did before having this problem. Its LED blinks as its plates spin and all cooling fans including the graphic card's fan run normally.

I tested the graphic card and the monitor on a different working PC and they worked fine. Also, I removed the sound card and all optional/non critical hardware from my PC for testing and still nothing. Starting up in safe mode is not possible because I can't see anything on screen. Besides, I don't think the computer goes far enough for me to try it. Any more ideas my good friends? Your answers are very appreciated. Wink
