    I have the GeForce 8600 GT, and I have been noticing a problem with my graphics-heavy games.

    Every ten minutes or so, the frame rate will slow down to something pitiful like 2fps, and I'll have to stop playing - a tough task in online games. It usually lasts for anywhere from five to ten minutes, and will then, with just as little warning, resume at full speed.

    I have only been able to pin this on the graphics card, as I don't see it happening in any other instances than graphics heavy games. If it were consistent to a certain game, all the all the time, or if the effects were fixed by moderating graphics options, I would not be confused.

    The thing is that it is not consistent. It happens on multiple games, and it happens on older games that my computer should run flawlessly, that lesser cards and rigs have run perfectly. I have completely undercut the game's performance settings to see if less work on the card will equal more performance, but there has been no change. It still continues to sporadically crater, and I am completely bewildered as to why or how to fix this problem. The game will work fine half the time, then work terribly the other half. It seems to me that if it were a problem with the games being too labour intensive for the card, it would be consistently occurring from the moment the game is loaded, not intermittent and without being context-sensitive to graphics-heavy situations such as smoke, etc.
    It is very impudent when my computer tells me when to take a break, lol.

    Here is my rig. Any help is appreciated.

    This a custom box or generic? Sorry, offhand I can't tell, haven't had time to do any homework - simple yes or no would do ....

    Good JR, thanks for the deeper focus. While familiar with heat sink types I still have my attention fixed on a BIOS adjustment.

    GF, you might be right with the BIOS, yet this remark in the other forum: Apparently my fan is operating at 0% leads me to a finicky fan? :doubt:

    Download HWMonitor and run it whilst playing the game. See where your Max temp is hitting during gameplay. 65c is just about safe, 70c + though ... that is too hot. Ideally below 60c is good.

    Try this as well. DPC Latency Checker, it's worth running to see if you have any driver issues or hardware clashes going on. It wont give an exact pointer to the problem but it does graph any current latency troubles, if any.
