Hi guys, I was using Pentium's G5500 integraded gpu UHD630 without problem untill I got an ASUS STRIX R7 370 DirectCU II OC 4 GB. After I launch a game in 2-3 mins the screen loses signal and I have to restart the PC. I was using a Deer 450Watt PSU and I thought was not enough so I purchased a Thermaltake Toughpower 700 W0105. The problem still exists. it does not lose signal only when I have the GPU fully underclocked with MSI afterburner where I lose FPS in games.

Note that the GPU's temps don't even get 60 degrees Celcius at 100% usage.
The problem does not exist when I stress test the card with FurMark where the card went even to 65 degrees.
I changed the thermal paste of the GPU with a new Arctic Silver MX2 and still the problem exists.

PSU https://www.newegg.com/thermaltake-toughpower-w0105ru-700w/p/N82E16817153035

So what's the problem when it is not the temperature and the PSU is enough to hande base clocks and even overclocking? If you need any more info I can give every spec.

Furmark is not a great way to stress test your system, in my experience it will use lower core clocks than normal because it's more a stress test than a real 3D generating test.

But that doesn't explain why your card can't run games at stock clocks.... Did you install the correct drivers for the card?

Yes, I've tried 2-3 different versions of drivers and now I have the latest.

Hey, I tried to clear install GPU driver after cleaning in safe mode the Intel ones and everything from GPU and Audio drivers with DDU from a tutorial I found on the site. Then I installed the latest stable drivers and the problem seems to got solved half a day now.

Deer 450Watt PSU? Can't see any result from Google Search. Might be of poor quality. If you have a spare PSU, stick it in and let me know if it works.

EDIT: https://forums.tomshardware.com/threads/is-a-450-watt-psu-enough-for-a-msi-gtx-750-ti-2gb-oc.2666754/ says Deer is of a bad quality PSU.

I posted an update, maybe you didn't see before you post. It was about drivers issue. The Thermaltake toughpower 700 which is a good PSU didn't fix it (I think it was not a PSU prob actually), so regarding the problem PSU change was not a must. Anyways I got a better PSU so i can overclock the GPU and RAM now.

UPDATE: Finally the problem still exists. I gave the R7 370 to a friend to test it and had no problem neither to stock nore to overclock. The GPU had no problem. I got an RX 580 from another friend to my PC and I have the same problem. So I switched RAM stick to slots and tried one stick each time and the same problem exists, I get a restart. So it is not the RAM either. The only thing it may have problem is the motherboard, but why it does it only after some gaming? At office work I have no problem and also I have no problem with RX 580 clocks underclocked.
