Solved My entire screen flashes green for a brief second.

April 14, 2018 at 11:19:05
Specs: Windows 10, 8gb DDR4 something
I have been getting an all screen "Green Flash" and my screen reverts back to normal. My system works fine and I am able to pass 3dMarks "Firestrike" and "Timespy" tests with ease so I was thinking that it probably isn't my GFX card and out of my whole system, THAT is what I don't want to replace being a RX 480 Radeon card and all.

It is just that when the entire screen flashes green and then pops back to normal, I was thinking of the HDMI cords but I tried other cords so it can't be that. "Gun to my head" and if I had to pick, I would think it would be the processor but my pc doesn't crash and it is relatively stable.

It is just that this green screen crap needs to go as when it started before, I both downgraded both my CPU and GFX settings to a lower Mhz in Bios and it didn't change this problem. Sometimes, it stays green for longer l

I truly don't know what I need to look at?

The first things I would try would be the card edge cleaning (mentioned twice now) and trying a different monitor (also mentioned). The next thing I would try is substituting a different power supply if available, if the power supply is poor quality, under powered for the system, or going bad then voltage fluctuations may cause this BUT since there is no reported CPU problems, is less likely.

Things that I have tried to fix this problem as it has been going on for a month or two now.

I have tried a fresh Windows install.
Downgraded Windows to 8.1 but the GFX card sorta needs Win 10...urg.
Underclocked both my CPU and my GFX card.
Tried other benchmark programs...and I ran the "Stability" test as well, all passed.

I'm just clueless on what I am missing.

Could be an indication that your monitor's on the way out. See if it happens on a different display.

Reads like an intermittent connection in the signal path - or within the display connections internally.

Have you tried removing the graphics card, cleaning its edge connectors (use a soft pencil style eraser - not something hard/abrasive); wipe the edge connectors afterwards with a lint free soft cloth (even a kleenex). Re-insert into tis slot firmly. Remove and re-insert again firmly; remove and re-insert a third time- firmly. Restore power and see if situation has improved/resolved?

Be sure to remove all power into the computer before removing the graphics card.

Since you mention a specific graphics card I'm inclined to presume this is not a laptop; hence my suggestion re' cleaning card contacts as above.?

Make/model of both computer - and display would be useful.

Lack of red and blue can cause a green screen. Most likely a hardware fault, such as monitor or its connections which should be checked first as given. Display adapter card is another possibility. If it is a separate card clean its edge connectors with a soft pencil eraser then push it firmly home.

I doubt this is either the CPU or a software fault.

Always pop back and let us know the outcome - thanks

Please list your system specs, including the make/model/wattage of your power supply.

Does the screen turn solid bright green, or is the problem that
the red and blue go away and only the green works?

When does this happen?

How often does it happen?

What is the longest it lasts?

Thank you. As far as the cleaning of the card, I did a rather good job before and it was working well until the time when I wrote and I was more panicing over seeing the Green screen again. I just wanted to hear from those who are as experienced as I am but slightly more here or there to see if I was right in this manner and I sorta was.

My computer is stable but as a precaution, I ordered 4gbs more of DDR4 ram as I only had 8gbs before and I tend to play graphic heavy games and run quite a bit in the background. You would think that 8gbs would be enough but you can always "thank" Windows and Microsoft in giving you far more than what you ever would use or care even the slightest about.

As a side note, I do use the "Sptbot" program and I turn off everything I can turn off from autorunning and my pc is as "clean" as I can make it.

If above, I personally would like to give you my thanks in confirming pretty much what I was thinking but also in giving me a slight of relief that I didn't fry my GFX card.

I believe the RX 480 is a 150W card. 75W from the PCIe slot + 75W from the 8-pin PCIe plug. If you have a cheap/generic power supply, it could be supplying dirty power to the card & causing problems.

I thought that as well but I am running a brand new 650 watt from an 'okay' brand. It wasn't of the cheapest set nor one of the best but since I originally wrote the above, as long as I keep what is open down in numbers, I haven't seen the Blue Screen and I often leave the PC on all of the time. However, I saw it once again when I had a lot of crap open from my son.

To remedy this problem, I bought, urg, 4 more gbs of Ram of the same speed as before.

We went through cleaning the card edge connecotors routine... Did you per chance dothe same routine with the RAM mdules? Might be worth a go?

Incidentally the remove/re-insert several tmes routine s to clean rhe socket connections too, as they can also becme oxidised as can edge connectors on actual cards and RAM.

Install HWMonitor and give us the temp readings min/max after fresh start and idle 10 minutes, then actively using for 10 minutes. If the temps climb fast and high then it could be a thermal issue which we would have further recommendations to diagnose and fix. While you are at it give us the min/max voltages on the 12V, 5V, & 3.3V rails because fluctuations of more than 5% from their nominal values is not acceptable and may mean that the power supply is bad (even if fairly new).

SOLVED: I truly solved this problem but not by any of the ways up above. Although I really did select the best one and used it's advice.

What worked for me and I highly suggest others in using this as well if need to be is to use a "HDMI to DVI" converter cable and use the DVI connector out of the PC. This way for me at least, the "HDMI" cable wouldn't constantly fall out of the pc as the DVI is screwed in.

The only drawback to my knowledge is that the DVI doesn't carry sound, and since my Monitor doesn't have speakers built in to it, this was a loss of nothing but the screen flashes and video problems are GONE.

Also note that perhaps the graphics card or at least the HDMI jack on it is not great. One day, unless you replace the machine first, you may upgrade the graphics card and with a new card, maybe the HDMI cable will work properly as intended.
Anyway, good news that your system is workable and not a continuous source of annoyingness.
