Screen flickers black but everything still works

phoenix4383 · Feb 1, 2015

So I've had this graphics card Sapphire Radeon 7850 HD 2gb DDR5 for about 1 and half years. It's had zero problems. But about 2 months ago I replaced my thermal paste on my cpu. Starting this month my computer has random times where the screen goes black. Like everything still functions but the screen just goes black.

I can still click on things during the "5 sec" of black and do things like play games. But these are kinda random and worry me.

Is this a problem with my power supply or my graphics card? Or may I have improperly applied thermal paste.

Cpu: Intel i5 3570k Ivy Bridge
PSU: Corsair HX750

Don't quite remember what my monitor is but I can pull up a receipt if needed.

Does it flash black or does it just go black and stay like that? Also how do you resolve the issue? Do you turn the monitor on and back off again or just restart the PC?

Also sometimes it can be a driver issue, have you updated it recently? Same goes with JAVA. Answer those questions for me and I'll try help you further.

It flashes black and returns to the screen. It goes black and I do nothing and it'll revert back. It's not like it completely hinders what I'm doing in the background. It goes black for a second then reverts back to my original screen or whatever I had been doing.

As for driver/updates. I have not recently updated java and as for my graphics card driver. I do not believe I have updated recently in the past 4-6 months.

And as for my cpu. Using the intel extreme tuning utility. My cpu is clocking in around 45-51 degrees. I do realize that the intel software is not as potent as others but even so. That number seems to be a tad high.

Ah ok, well it's none of that by the looks of it then. It's a tad bit hot if it's bothering you reapply the paste, normally what to go is you just put a pea sized drop in the middle and it should spread out evenly. However I don't think that would be causing the screen to flicker, more just a coincidence.

Can you maybe do some troubleshooting with another monitor? It could perhaps be that it's giving out itself. It's hard to really pin point it tho it could be a number of things.. Maybe even the backlight is giving out.

Although I'm hesitant to believe my monitor is giving out on me. I have recently bought this one maybe about a year ago (recent pft). So I may do some troubleshooting with that as I have a few older ones that may work. I'll see to that.

On another note. Another one of my friends had a similar problem and said the issue stemmed from his gpu fan. Is it possible that my gpu is not receiving enough cooling and is therefore overheating? He said he upgraded his gpu and made sure it came with a better chasis and fan. He has not had problems since. ATM I'm not in a situation to go out and spend another $150+ on another graphics card. (I can see how flexible I am on this)
Cooling and noise is another problem. Still in high school and my parents complain about the noise from my original fan set up. I have had to dumb it down to less fans and therefore less cooling. Is the hydro cooling such as the corsair cpu cooler any good? I "heard" that it is somewhat decent and quiet. Any tips on that although I see that you're moreover a gpu expert.

Yeah just see if the monitor is giving out, run one of the more high demanding games and see if the flicking appears. If it does like you mentioned it might be a GPU heating issue, did you start seeing these issues when you removed the additional fans?

Water-cooling is certainly more effective and quieter however you'll be looking at spending around $100 for just a CPU one, the GPU water-cooling becomes even more difficult because you'll need to find a block that actually matches your GPU and you'll need to most likely have a custom loop design done. This is a complicated option and expensive.

I'd suggest you do some cable management so it increases the airflow in the actual case, here's a guide; http://www.gamersnexus.net/guides/892-basics-of-cable-management

That is a very cheap effective way to bring down the temperature, along with cleaning your case and fans of any dust. If your parents are complaining about the fan noise you can find some quieter fans on the market that aren't too pricey. Here's a example; http://www.scorptec.com.au/product/Cooling/Case_Fans/36457-AC-F12-PWM?gclid=CIHImIvzycMCFRcIvAod0I0Akg

You could perhaps try do this and see if you get any changes with the flickering, either way it will improve your overall performance of the computer. Here's a GPU temp sensor you can use; http://www.gputemp.com/

Hope that helps man. Let me know if you need further help or select a solution, you can also private message me later on if you wish.
