Possible issue with HX750?

Recommended Posts

Hi everyone,

 

My system reboots in less than 5 minutes of running a 3D game, yet I can run a FurMark test without the PC rebooting. I think it may be the Power Supply, but I'm not sure. The voltage seems to check out.

 

Can anyone help me?

 

Thanks,

Luk

Hi,

 

My temps are pretty decent. Details are below of the steps I've done on the Graphics Card, CPU and Power Supply.

 

Graphics Card


  • Ran FurMark GPU Stress Test, 1920x1080 full and not full screen (temp held at 63c)


  • GPU is under 53c when PC reboots during games at much lower settings than the FurMark test (even rebooted at 44c when starting World of Warcraft)


  • Completely removed driver, clean install of newest release driver


  • Loaded multiple older drivers (removed old and performed clean install)


  • Loaded base windows driver (removed old and let Windows install driver)


  • Removed and loaded different versions of DirectX (9.0c and 11)


  • GPU Fans are working


  • Ran games on much lower resolutions, adds a few minutes before reboot.


  • Tested underclocking GPU and it adds a few minutes in game, but still reboots.


  • Replaced wires to GPU with new wires.


  • Tried all PSU ports with new wires to GPU

 

CPU


  • CPU is at 43c or less when it reboots running games


  • CPU didn’t go above 55c running Prime95 test


  • CPU Fan is working


  • Checked CPU for overclocking and has an automatic overclock function


  • Disabled automatic overclock, no effect.


  • Underclocked CPU, unsure of effect. It seemed to add a couple minutes, still rebooted.

 

Power Supply


  • Checked voltages in BIOS settings: 3.3v, 5.0v, 12.1v


  • Checked voltages with Power Supply Tester: 3.2v, 5.0v, 12.1v


  • Checked each power cable with the Power Supply Tester resulting in the same readings

 

So, all the PC parts are moderately cool during the games and they are hotter during the stress tests. That tells me it’s not a heat issue. Cleaned out and reinstalled all drivers and I would think a BSOD would result for most driver issues.

 

The only thing I could possibly see is the Power Supply Tester reads 3.2v on the 3.3v rail, even though the BIOS reads it as 3.3v.
