My PC Monitor keeps going blank and then coming back on again? How can i fix this?

Question

It does it repeatedly with no real pattern where it just goes black and then back on again every 2-10 seconds. I run regular virus checks so i dont think its that.

Answer 1

there may be  a loose contact somewhere---shut down the computer--turn off power and remove the monitor data cable and refit it again---or there could be a problem inside the monitor(a relay inside turns the monitor on/off) in which case you need to take the monitor to the shop to repair it.

Answer 2

I think it could be a contacts issue with either the VGA/DVI cable or the power cable, or it could be a graphics card issue.

The next time this happens check the power indicator light to see if there's electricity. If the light is off, then it's a power cable contacts issue. Try and push the cable furthur in or tighter.

If the light stays on then it could be a VGA or DVI cable problem. Tighten the contacts and see if the problem stops.

If it still continues then it could be a graphics card issue. Swap the graphics card in your PC for either a spare one you have or borrow one from a friend for a week and see if it still occurs. If it does not then you'll have to replace the graphics card with a new one.

If it still occurs then it could either be a faulty monitor or cabling. Diagnose it by using a spare cable or monitor and see if it still occurs. If it doesn't problem solved.

If it STILL occurs then the last reason I can think of is that you're using Windows Vista! LOL. Seroiusly, I won't be too surprised if that's the cause of the problem. Vista's a rubbish OS. XP rules! :-D
