Both monitors lose connection while computer is still running

[Retro55]

For a few days now my computer has been losing connection to both of my monitors while the computer itself still runs. After the monitors lose connection the audio still plays for half a minute while stuttering a few times before it stops. This generally only occurs while i'm playing games, mainly first person shooters. Before this issue started occurring I was having troubles with my internet, but as soon as i fixed that problem my computer started doing these weird crashes. I'm still not entirely sure how i fixed my internet problem but I did take out a a network card that had problem staying connected and uninstalled the driver for it and another wireless adapter. And before the network issue i was having problems with random restarting without an error message but that stopped occurring after I took out my card and put it back in.

At the moment the fan on my GPU is disconnected since it rattles a lot, but the temperature still doesn't exceed anything over 70 degrees Celsius while i'm playing games. On the other hand my CPU is reaching temperatures of 85 degrees, which i'm not sure if it is a high temperature.

System specs:
CPU - A6-6400K APU
GPU - Sapphire Radeon HD 6570 4GB
MOBO - ASRock FM2A55M -HD+
PSU - ATX 12v 2.3 VER (model no. RK - P650)

That's a bit high for your CPU, what kind of cooler is it?

 

[Retro55]

Just the stock fan that came with the APU

Max operating for that APU is 70 degrees.

Which temperature do i look at on WHMonitor?
The CPUTIN says 42 degrees while Package under the drop down for the CPU says 80ish

Another thing I forgot to mention was that when the computer does lose connection to the monitors, when I press the num and caps lock keys the lights dont change.

HWMonitor doesn't report correctly for APU's due to the Graphics being on the same die as the Processor.
The best way to get an accurate temperature is through the BIOS.
Blow as much dust off the board from the VRM and CPU area as possible, especially the CPU cooler, you may need to add another case fan to improve air flow through the case too.

Might try AMD Overdrive

CPUTIN is motherboard CPU temp sensor.

the PSU might be failing , the system power consumption is not much though

I would check the system stability with only one monitor and then without the video card . a virus scan is a good idea too .

Would this be anything to do with my processor because the system keeps running after the monitors lose connection?

That makes me suspect your graphics card. But your symptoms could be from a failing PSU. That RK-P650 PSU is obviously not a name brand supply for I can find no information other than one used supply being sold on Gumtree and one forum poster complaining they can't find any info on it either. I always want to ensure I am feeding my electronics good, clean, stable power before troubleshooting potential hardware problems so I recommend swapping in a known good PSU and see what happens.

If still having problems with a different PSU, I agree with little cat and suggest you scan for malware and try with only one monitor. Swapping in a different graphics card and seeing what happens would be very informative.

I think it unwise to disconnect a fan just because it is making too much noise. If it is still spinning, it is still blowing off some the heat. Too much heat can greatly affect stability - or worse. The fan should be reconnected and a replacement fan immediately ordered (or swap out the card).
