Graphics Card
- SAPPHIRE Radeon HD 6870 1GB
- No overclock

AMD Catalyst Driver Version, and Driver History
- Catalyst 14.4 (beta)
- last 2013 stable release also tested

Operating System
- Win 7 x64, pre SP1
- No other OS tested

Issue Details
- System restarts after variable length of time while playing graphic intense games. Games like Minecraft do not cause the restart. Upon restart, screen stays black and motherbord POST error beeps refer to the system not finding a GPU. GPU fan spins at 100%. After forcing the system off via holding the power button and turning system back on, GPU is detected and system boots normally.

Motherboard or System Make & Model
- Asus M4A79XTD Evo

Power Supply

OCZ ModXStream Pro 700W Modular

Display Device(s) and Connection(s) Used
-LG 37" TV connected via HDMI @ 720p

Applications and Games

- Starcraft II, Diablo III, BF3, Simcity (2013), The Sims 3; to name a few

CPU Details
-QuadCore AMD Athlon II X4 640, 3000 MHz (15 x 200)
-No overclocking

Motherboard BIOS Version
- ASUS AMI 2102 (2102 is latest revision offered a ASUS's website)

System Memory Type & Amount
-G Skill F3-12800CL9-4GBRL x2 -- DDR3-1333 (667 MHz)

Additional Hardware

- 2x 1TB HD in Raid 0 array, 1x 1TB HD - 2x DVD optical drive, D-Link DFE-530TX+ PCI Fast Ethernet Adapter (rev.F) (on-board Gig-E port dead), Creative Audigy 2 ZS audio card (PCI)
- 2x 120mm case fans, 1 rear, 1 front of case (expanding soon to 5x 120mm)

Additional Details
System has been completely wiped and reinstalled (recent maintenance). Problem persists even after moving to new PC case. GPU temperature idle around
102-104F and during gaming will be 130F+.

Motherboard was involved in lightning strike, which caused dead Gig-E port (surge came from cable line/modem, not house power). Voltages are a bit off, which causes me some concern.

The GPU fan speed dips slightly when doing normal PC tasks, such as resizing this composer window or scrolling a web page.

Edit: Also supplying voltage readings from AIDA64

I ran a burn-in utility to put the card under stress (OCCT) and the card got about ~10 minutes in, was about 78C and then went to black screen, rebooted and had the POST error beeps.

This action has no effect. I was able to reproduce the issue in less than a minute.

It's very likely your power supply.  It has two 12V rails of 25A each.  One supplies the motherboard and processor.  The other has to supply power for everything else.

I would recommend a new single-rail PSU of no less than 750W.  Something from Corsair or Seasonic is a good bet.  If it costs less than about $80, it's cheap junk.

OCZ is a mixed bag, as their power supplies are split between 6 different manufacturers. In this case, the ModXStream Pro 700w is made by Sirtec. Going by The HardOCP review the results are not impressive, especially since it failed at 45°C, a not uncommon temperature when you combine high ambient temps, not very high efficiency, high load, and especially with a top mounted PSU orientation. So I would agree with Thanny that it needs to be replaced by something of quality, preferably SeaSonic or Enermax, or for a little less the PSUs they make (Corsair, XFX, PC P&C, Sapphire), of 750-850w, both for peak efficiency and longevity.

I bought a corsair TX850V2, been very happy with it. Single fat rail.

My review.

With one video card its overkill but generally lower loads are more efficient.

You could try bumping up the cpu voltage to ~1.45...1.46v to see if everything stabilizes.

Before buying a new power supply...try getting better airflow experiment of a room fan forcefully blowing air into the case with the PC door off.

Make sure ANY filters are clean on case cooling, too.

The random restarts may be more likely due to the psu, as the others have suggested but -

'Burn in' = great way to kill a card, I reckon. Especially if there is already a problem. I ran Furmark on a healthy ATI 1950XT back in '05-'06 ? It borked the card. Started running 90+C and artifacting after the test - Never again. Games are a hell of a lot safer, and are stress test enough.

Thanks to everyone who replied. I was able to swap in a temporary 630W power supply to test stability under stress. The system was stable during my tests, so I can definitely conclude that my 3 y/o power supply is unable to handle that kind of load any more.

Vegan, thanks for the suggestion. I will keep that in mind when shopping around, though the 630W will have to do while I wait for funds to be available.

Dinwiddle, I only use the burn-in utility to get the card up to operating temps because once I'm there after I close out of the test, that's when the computer crashes. I was not able to reproduce the crash with the new PSU. I would never use a burn-in for any type of long-term testing.

 

Again thanks to all of you. I appreciate all of the help.

budget at least $150 for a respectable enthusiast PSU
