HD4890 - pc resets itself when playing games - help pls


Hoping you can help me with an issue.

I've recently built a new build

Have tried installing and playing several games. Literally get a minute or so into the game before system resets itself (no lockup / freeze - just resets).

The games I've tried so far have been World in Conflict, Need for Speed Shift, Battlestations Pacific.

Here's my system
i7 920 - running at 2.67ghz
Asus PT6 SE
6gb ddr3 ocz memory
Sapphire ATI 4890 HD
500W NorthQ PSU 4350GP-FL
Crucial M225 64gb SSD
Windows 7

Does a system reset instantly point towards a obvious culprit?
- memory issue / latency / voltage?
- power supply / overheating / insufficient watts?
- graphics card / driver issue?
- cpu overheating?

I'm thinking that either I have a faulty graphics card or a PSU that isn't up to the job (even though the graphics card says a 500w PSU should be fine). The graphics card is running at stock speeds (870 / 1050)

I've got the latest drivers installed via CCC, so I don't think they're an issue.

  4. this is the graphics card

    11150-05-21R - 1GB Sapphire HD 4890 Vapor-X, PCI-E 2.0, 4200MHz GDDR5, GPU 870MHz, 800 Cores, DVI/ D-Sub/ HDMI/ DP

  5. any more advice?
  6. If you can try another PSU, preferably one of a decent brand name (Antec, Corsair, Seasonic, and many others not mentioned) that should be your first diagnostic test.
  7. I don't have a spare psu lying about
  8. Not much else you can do, short of wiping your HDD and reinstalling/updating everything. If the problem persists, it is a Hardware issue. With your symptoms (complete computer reboot after a short time gaming) a faulty PSU seems to be the culprit.

    Either return the PSU you bought, borrow one, or buy a new one. If it is a faulty PSU, nothing short of a replacement will diagnose/fix the issue.
  9. So are we ruling out the graphics card as a culprit?

    I'm reluctant to spend another 100-200 on a replacement psu if that doesn't end up fixing the issue

    was hoping to be able to determine the issue before succumbing to replacement parts
  10. ps - i reinstalled W7, rand 3dmark vantage and same issue occurs
  11. any more advice?

    is the only way to buy a new psu??
  12. If the graphics were slow, and full of artifacts (obvious graphical glitches) then the card might be a culprit. But complete restarts, especially repeatable shortly after starting a higher power task (like a graphically intensive game) screams PSU issue. I can't tell you how to obtain another PSU for testing, but you definitely need one. If it is a new build you should be able to return it for a replacement/credit at the least.

    A good PSU doesn't have to be even as high as $100:
    Antec 550w PSU, 64.99 free with shipping. Reliable brand that makes great power.
  13. I have the same problem but I have a different graphics card and my computer restarts after a couple of hours gaming on "Need for Speed World" and today it restarted it's self after being on the login screen for "APBR - All Points Bulletin Reloaded" for about 15 minutes :/

    I checked the event log and apparently the problem of mine is called "Kernel Power Event 41"

    Any help would be appreciated! :)

    My specs are:

    Processor: AMD PHENOM II X4 970 AM3 3.5 GHZ QUADCORE
    Memory: GEIL 8GB KIT DDR3 ENHANCE PLUS C9 1600/1750MHz
    Hard Drive: WD CAVIAR BLUE 3.5" 1TB 7200/32MB/SATA3
    Graphics Card: XFX HD6670 800Mhz PCIe/1GB/DVI/HDMI/DP
    Optical Drive: ASUS DVD RW 24x BK/ +/-/DL/SATA

    Thanks in advance!
  14. Do you have a spare card to test your rig with? The 4890 is known to have a rather short overall lifespan.

    I have the XFX Radeon HD 6670 not the 4890.
  16. Oh and the computer is like a month old, so everything is still pretty new
  17. Hey I am having the exact same problem. The video card is most likely nit the problem I've switched out 3 and it still fies it. On board graphics works which is weird. I have been trying to find a solution for 3-4 weeks and have tested everything but psu and mobo but I doubt it is the mobo. Lemme know if you find a solution I'd be extremely grateful. My computer is also brand spanking new just built it.
