New i7 Sys Reboots During Games

  1. Last month I built a new system that works fantastic until I try to play some games. The computer will reboot itself with no errors. Some games I can manage to play for a few minutes, others in seconds, some at specific points in the game, others quite randomly.

    So far, I've tried rolling up and back all my drivers, reseating all the cables, cards, and memory, and reinstalling Windows to try to fix the issues....the reinstall actually seemed to make the problem worse.

    I don't overclock and I don't believe temp is an issue except for possibly the video card. From a cold boot, there are some games I can run that will reboot the system in seconds....not sure if they could heat up the card that fast. I also replaced the memory as I was previously using incompatible DDR3 memory on this unit. It had the same problems with them and I was hoping the new memory would fix everything.

    Here's my setup:

    MSI X58 Platinum SLI (bios updated)
    Intel i7 920 CPU
    EVGA GTX 280
    Crucial DDR3 6GB PC3-10600 1333MHz
    SB Audigy
    RaidMax 730W TX-730SS

    CPU temp: 31C
    IOH temp: 56C
    SYS temp 44C
    GPU temp 68 - 85C (gets hot...not sure how to fix this. Even opened the case and had a fan blowing on it to test.)

    I appreciate the assist.

    Someone may say different but I think that your Graphics card heat could be causing the system reboots. It’s a possibility that it is rebooting as a precaution to try and stop any damage.

    I would download speed-fan. Set that up and while running the system try and keep an eye on the temp and also the voltage your system is throwing out. It could be that there’s just not enough juice to run.
    Then if there are no problem load a game and if you can keep speed fan on top and see if anything tragic happens.

    There is a guide and download here

    Thanks for the advice! I installed SpeedFan and ran a log for the temps and voltages while playing HL2. Looks fairly steady except for the 12+ Volt....looks like it was below the range near the end before the reboot. Of course, I'm not an expert at PSUs so I don't know for sure.

    Any thoughts from this info:

    Hmm if you can i would try a new PSU. It should be 12V +- 5% so at the moment you have ranges of

    12.06

    11.97

    12.14

    11.88

    I'm fairly sure it shouldn't go down to 11.88. I'm not to sure if Ive got the percentages right however so someone may need to check but i think 11.88 is to low and 12.14 is seemingly to high so i would test with a new PSU at this point.

    You're right, its no more than 5% flux on the rails.

    Check the fan speed on your gpu. That is relatively hot. And dont ever buy another Raidmax psu for a system like that.

    Which brand of PSU would you recommend?

    I got the Raidmax based on the quality of the cases they make and the reviews on NewEgg.


    BTW - I found the following on EVGA's site:

    "Video card temperatures typically range from 40C to 80C. Most high end video cards such as the 78xx, 79xx, 88xx series typically display temperatures 50-70C idle and up to 80C-90C at load. The heatsink and fan assemblies attached to the video cards are specifically designed to reduce temperatures as much as possible."

    Makes me feel better about the card temps.

    Update folks....I'm returning my original PSU and I got a Corsair 850W at Frys....So far it's fixed the issues I was having. I think I needed more watts and amps.

    Thanks for helping me brainstorm that one, guys!

    Np, i thought it was the psu for sure, glad to help. I think that's why we're here :p

    Awesome :)

    Thought you might have found a Core i7 bug then ;)
