Hello
I am fighting with this awkward problem for a few days now
I have the following configuration (rather old already):
My computer hangs (black screen and then restarts by itself) randomly several times a day
I can easily reproduce this by running Heaven Benchmark 4.0 in DirectX mode (in OpenGL mode it runs without problems. Valley benchmarks runs normally in DirectX mode)
I can also reproduce it in DaVinci Resolve video editor, by playing some time with the sliders - forwarding video clip forth and back (which should be much less stressful compared to Heaven benchmark)
What I tried until now:
I am lost now. I do not know how to verify if my GPU is defective or I have some software problem...
Any help would be appreciated
I am fighting with this awkward problem for a few days now
I have the following configuration (rather old already):
- Intel Core I5 750
- Motherboard ASUS P7P55DLE
- RAM - 4 x 2GB DDR3
- Radeon R9 380 4GB (the video card was bought second hand an year ago)
- SSD + 2 x HDD 7200rpm
- PSU Chieftec GPS-550AB A
- Windows 7
My computer hangs (black screen and then restarts by itself) randomly several times a day
I can easily reproduce this by running Heaven Benchmark 4.0 in DirectX mode (in OpenGL mode it runs without problems. Valley benchmarks runs normally in DirectX mode)
I can also reproduce it in DaVinci Resolve video editor, by playing some time with the sliders - forwarding video clip forth and back (which should be much less stressful compared to Heaven benchmark)
What I tried until now:
- MemTest86 for a long period of time- no problems found
- Prime95 for a long period of time - no problems found
- Some tests for the SSD
- I used DDU to remove my videocard drivers and reinstalled them
- I even asked a PC technician to test my PSU and according to him - it is ok and this is probably "some kind of software problem"...
- I did not find any way to force reinstall DirectX in Win 7 - it always says that I have the latest version (even if I do a registry hack and put some older version in HKEY_LOCAL_MACHINE\Software\Microsoft\DirectX\Version)
I am lost now. I do not know how to verify if my GPU is defective or I have some software problem...
