Computer Crashes (No BSOD) While Gaming-- Could it really be my PSU?

My gaming rig is a bit outdated, especially when you look at the graphics card. So, I've done my searching high and low all over the forums here and almost every person's "Computer Crash" with no BSOD while gaming is related to the PSU not having enough wattage. However, my PSU has enough wattage... at least I think it does?

CPU: AMD FX-6100 3.3GHz 6-Core OEM/Tray Processor
CPU Cooler: Corsair H80i 77.0 CFM Liquid CPU Cooler
Motherboard: Asus M5A99X EVO ATX AM3+ Motherboard
Memory: Patriot G2 Series 8GB (4 x 2GB) DDR3-1600 Memory
Storage: Seagate Barracuda 3TB 3.5" 7200RPM Internal Hard Drive
Video Card: EVGA GeForce 9800 GTX+ 512MB Video Card
Power Supply: Corsair Enthusiast 650W 80+ Bronze Certified ATX Power Supply

The crashing only happens when I'm gaming. I've tried doing CPU & GPU stress tests separately and at the same time, and I can't get the PC to crash... Until I open up Guild Wars 2 where I can play anywhere from 5 minutes to 10 minutes-- I haven't tested any other games.

Perhaps it really is my PSU, but maybe it's just time for a new graphics card?

Any ideas? :)

  1. Looks more like a gpu driver error. Go into Windows Event viewer and see if there are any critical errors causing the shutdowns.

    A 9800 gtx+ only requires a 450w psu, so even if it was very old, your current psu at 650w should be more than enough.

    Gpu stress tests don't run the full range of drivers a game can use, unless you run something like MSI kombuster, and run through all the separate tests for different applications.

    The issue can also be related to hdd errors. At boot, punch f8 for boot options before windows starts, use command prompt, and type in 'chkdsk /f'. This'll fix any errors hopefully.
  2. Nothing is in the event viewer for critical errors other than it telling me the last shutdown could have been due to loss of power.

    I've been on the latest driver version as well.

    I'll give kombuster and a chkdisk a try.

    edit; kombuster ran with all kinds of different tests, didn't crash. CHKDSK found no errors. Reinstalled graphics drivers.

    Still crashing. Now, when I say crash, I mean my screen goes black, my audio cuts into a "Buzzzzzzzzzz" sound, and the only way for me to get my system back is to press and hold power.
  3. Kombuster will punish a gpu a lot harder than almost all games, driving it to 100% gpu usage. That's maximum power draw. How is your gpu temps? It could be the psu, I'm just doubtful of that. Psu shutdowns are full. You'd not get a lockup like that. Very possibly it's the gpu and your testing didn't take the time to really heat up the card. Is it clean? Those blower style cards will get debris inside the cage on the fins, which makes the vram and VRM's heat up, which could be a cause for gpu shutdown. Since the audio is also tied into the graphics, a gpu shutdown would explain the buzzing.
  4. My first bet would go to Hard Disk or Memory. HD is already covered above, so next to try is the Memory. Test your system with 2 sticks of memory, gaming and memory testing with something like Memtest86+ or so. But maybe its your PSU. A stress test for gpu will only stress test your gpu and not your cpu or other parts. If you game, all cpu and gpu could be stressed at same time. Can you underclock your gpu and play again? If this works, you could play until you get a psu replacement.
  5. No matter what I do, I can't get my PC to crash unless I play a game. I've tried doing stress tests on the GPU, and CPU at the same time driving usage to 100% constantly for up to 20 minutes, and the system is stable. Temps are decent. I've got a liquid cooler on my CPU and the fan on my GPU keeps it at 80-83C on average during the stress test. However, while playing games, it never climbs that high. My memory also checks out ok (it's also newer ish...maybe late 2014 I put that in?)

    I'm going to order a new card-- this card may be just reaching the end of it's life. It's been a strong card for 8 years, and I'd say that my game play will probably be severely enhanced with an upgrade. I'm going to throw in a GeForce 950 FTW. Should get here the end of next week, best case scenario.

    I'll report back if this solves the issue or not. If this doesn't solve it, sounds like I'll be getting a PSU-- I seriously doubt the PSU to be an issue, though. Echoing what Karadjgne said previously, the system would do a full shutdown if it were having issues, but it's not.
  6. Good luck. Hope it works.
