GTS 250 w/ Win 7 x64 Issues (please help!)

no i did not, although i heard something about ram voltages being half of cpu voltages or something? where do i go to check/adjust these? what should they be?

thanks

my friend came over and helped me set the voltages manually & pci-e frequency to 100, and it didn't fix the problem.

i also just ran 3dmark, granted with only 1 strip (2gb) of ram installed, and my score was 14,280 if i remember correctly. i am not familiar with the program, is there a certain thing i need to run/do?

i took some ram out, i have 3 chips 2gb each. i took two out, left one in. problem didn't change. then i switched that with another one, problem didn't change. that's the extent that i did that for...

just to refresh the problems i am experiencing:

1. if i run an aero theme, my display drivers?/video card? (not quite sure what it is) crashes about once every 30-45 seconds.

2. if i switch to a non-aero (high contrast) theme, the system is relatively stable, and can be up for hours until i try to abuse it by whatever means, lately i've been able to get it to crash just by playing an hd rip movie in windows media player. however, it didn't crash running through all of the 3dmark tests.

3. another problem, could be unrelated, but doubt it, is that my mouse cursors will randomly decide to freeze for 2 seconds then work for 2 seconds, then freeze for 2 seconds then work for 2 seconds. this continues on until i reboot. i believe this only happens on session where the display drivers crashed, and i switched back to a non-aero theme.

i am about to install vista on another hard drive to see if the problem carries over to a different OS.


thanks for the help guys, really can't wait to get past this so I can enjoy my new system and get on with my life already!

slowly but surely, making some progress.

I installed Vista on a different hard drive, booted up, installed all the updates, and upon reboot the mouse cursor started acting up again just like it did in windows 7. Now here's EXACTLY what the mouse is doing.

The cursor itself stops on the screen for 3 seconds, after those 3 seconds it wakes up and appears wherever it was moved to while it was frozen. Then works for 3 seconds, then freezes for 3 seconds, and so on. Also, the computer doesn't freeze, I can still type without any problems, ALSO the scrolling wheel on the mouse works while the cursor itself is frozen.

Does this sound like a video problem? I mean the mouse is doing it's job, even when it appears to be frozen, I just don't visually see the cursor itself moving.

I haven't had a chance to reboot since the boot up to mouse problem. I also wanted to keep that session going to see if I can diagnose it further. When I was running windows 7, the mouse problem was very sporadic, so it's hard to replicate.

What do you guys think? Sound like a bad video card? Should I just go buy a new one from best buy and try it, see what happens?

thanks

thinking about trying this one:

PNY - NVIDIA GeForce XLR8 GTS 250 1GB DDR3 PCI Express Graphics Card - VCGGTS2501X

PSU is an Antec EA650
Newegg.com - Antec Nine Hundred + EA650 Black Steel ATX Mid Tower Computer Case 650W Power Supply - Computer Cases

Just purchased the parts a week or so ago through newegg, so warranty shouldn't be a problem. Since I was running Win7, I wasn't going to try calling the vendor because I think they'd tell me to go screw myself (from what I heard from other people on forums).

I am going to try a different GPU tonight, gonna buy one from best buy to try. I will also try testing my RAM as you mentioned.

Thanks

You should only be using the top pci-e slot for that GPU.
