Screen goes black for a few secs

nutz 2,338 674 April 30, 2016 at 09:32 AM
For the past couple weeks my computer screen goes black then comes back on after a few secs. I deleted and reinstalled updated video drivers thinking it would solve the problem but no luck. I changed nothing nor added anything before this happened. Anyone have this problem before with a possible fix? Could it be hardware related? Thanks in advance for any help!

How often does it happen? Laptop or desktop? Operating system? Have you tried connecting an external monitor to see if it happens on that? That would rule out the monitor.

if the problem is pc, if no signal, monitor will say no signal, this isn't what you're saying, so if just black signal, you can see monitor's light bleed, better to see it at night.

if LCD backlight problem, no light bleed, pure black, try lower brightness see if help

I want to say it happened more before I updated the video drivers. Its so random now, id say a 1-2 times an hr. Sometimes an hr can go by and it doesn't happen. Running a desktop with Win7x64. I have a spare monitor that I will hook up and see what happens. Also when scrolling on Facebook the webpage starts to break up and get blocky. Closing the browser and reopening make it go away temporarily. Weird that it only happens on FB.

I do no get the "no signal' banner when the screen goes black. Just gets solid black for a few secs then back to normal.

A person hates you for 1 of 3 reasons. 1) They want to be you. 2) They hate themselves. 3) They see you as a threat.

Sounds like a graphics issues. Are you using onboard graphics (on the motherboard) or a separate video card? Try the other monitor, it will likely do the same thing.

Im running a Radeon HD 7900. Thats been my guess. Might try driver sweeper and reinstall graphic drivers again.

Seems a simple cleaning and reseating of the video card resolved the problem at least for now. My guess is the dust build up was causing the gpu to overheat. Finger crossed

Is it HDMI? If so, cable could be having issues causing a re-sync.

Would probably check my cables or power cord. Sometimes the simplest solution works.
