Windows 7: My Computer monitor doesn't show anything when I turn my computer on.

My Computer monitor doesn't show anything when I turn my computer on.

First of, my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.

But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.

Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so.

My question, Is the monitor responsible for the restart and what could be the reason for the flickering?

Thanks for a fast reply.

Welcome Pokeman5 to the windows 7 forums.

The graphics card might be your culprit. Please update your system configuration settings under user cp so that others can maybe help you.
Usually the monitor won't stop your machine from booting. The graphic card most likely be the cause.

There is also the possibility that your power supply could be defective or going bad. Lots of possibilities.

I had the same problem on my old computer graphic card was going bad and it would shut off my monitor and computer I also agree that it may be a power supply problem "lack of power or faulty"

Do you have a separate graphic card or is it a on-board card?

When you say "CPU" are you talking about the processor installed on the motherboard, or the entire tower unit (Computer)? If you swapped computers and still have the same problem I would think its the monitor thats got a problem. The BIOS or post screen is usually a low resolution screen so maybe its a resolution that the monitor doesn't support. Is it a CRT display or an LCD display?
