Gateway P7915u GTX260M

Recently my computer won't play 3d games (Madden 08, LOTRO, C&C, etc. It always starts ok, then eventually blacks-out and goes to the desktop. I did have an overheating issue at one point, did the thermal paste thing, and I'm ok now. Couple questions: Does it sound like hardware or software? More importantly...Is there a way to put a new GPU in this computer? Can I simply buy another motherboard and put it in here?

Thanks. Also please excuse my ignorance.

  1. Sounds like a typical heat and/or power issue. That could indicate an issue with the CPU, GPU, or motherboard itself.

    I do not believe you can upgrade/change the GPU in that system (except by installing a new motherboard).

    When it is running, how hot are your CPU and GPU getting? If you don't know, google and download/install hwmonitor. Run it in the background and fire up a game.

    Report back with the results.
  2. Hello:

    Sorry for the delay (Christmas stuff).

    I ran a little LOTRO and got these results:

    Operating System
    MS Windows 7 Home Premium 64-bit SP1
    Intel Mobile Core 2 Duo P8700 @ 2.53GHz 47 °C
    Penryn 45nm Technology
    4.00 GB Dual-Channel DDR3 @ 531MHz (7-7-7-20)
    Gateway Godzilla-N10 (U2E1) 58 °C
    Generic PnP Monitor (1440x900@60Hz)
    1024MB GeForce GTX 260M (Acer Incorporated [ALI]) 92°C
    Hard Drives
    313GB Hitachi Hitachi HTS545032B9A300 (SATA) 50 °C
    Optical Drives
    Optiarc DVD RW AD-7585H
    Realtek High Definition Audio

    That was the summary.

    Interesting....> I'm finding that if I run full screen 3d games on Battery, I have no problems. When I try the same on AC power, that is when I have issues. Strange deal... I've searched the net and this is not an uncommon issue with these computers, but I haven't seen a fix.

    I did have overheating issues at one point, tore it apart, applied thermal paste/cleanout. It got quite hot prior to me doing that, but I don't remember exactly how hot. It seems it was over 103 but I don't recall exactly. I'll throw some additional specs after this in case any of them help. Thank you very much! Sorry if htere's a better way to attach this.

  3. On DC power, the system downclocks components to reduce power consumption. On AC power, it runs at full speed and consumes more power and generated more heat.

    Like I said earlier, this sounds like a heat and/or power issue. It really looks like your video adapter is the problem (74C is very hot).
  4. That makes sense. Any way I can doagnose it? Or...would it be possible to downclock on AC so this thing will run?

  5. Sounds like you need to look at the heatsinks to ensure they are working well and that you don't have too much thermal compound. If these check out (clean your fans at the same time with compressed air), then a motherboard replacement may be required.

    You should be able to clock back your GPU in the Nvidia Control Panel. You can also adjust your fan settings to run at 100% all of the time (noisy, but will help with the heat).
  6. OK. I'll check inside, and try to clock back a bit. Can you tell me what adjustments I would make in the Nvidia control panel to clock back?

    Also. If it comes down to it, I've seen the motherboards on ebay from some computer shops. Is this fairly simple PnP-style, or will it take a lot of tweaking?

    Thanks again. You've been very helpful.
  7. Best answer
    Swapping a mobo is usually pretty easy. Just keep track of where all the little screws go.

    Download and install MSI Afterburner. Nvidia Control Panel for mobile GPUs no longer has the setting items to allow you to make adjustments.

    Afterburner will let you tweak your settings. Get it here:

    You also download and install SpeedFan as an alternative to tweak you fan settings. Get it here:
  8. Great. Thanks.

    Can you tell me the settings I need to adjust "down" to downclock?

    Thanks again!
  9. Reduce your core clock and possibly memory clock speeds. Also make sure your fan speed is set to max.
  10. Drop in 10 mhz increments and check your temps as you do so.
  11. Thanks. I'll try this out.

    I appreciate it.
  12. Good luck and have fun!

  14. Update:

    Wife got me a new motherboard for Christmas so looks like I'm going that route.

    Thanks for all the help!
  15. Good luck!
  16. Ha! Thanks! I'll let you know.
