Evga Geforce gtx 460 video card

Specs: Windows 7, AMD phenom 3.2ghz quad core
When my pc restarts my monitor wont find a signal until i turn the pc off then on, not that big of a problem but the other thing is whenever I do something like raising resolution to 1900x1200 which is the recommended setting and or set the video quality on youtube to 1080p my computer will freeze for a few seconds then restart. I checked online and most people said its overheating, I know its not OH because I downloaded the speedfan program and everything is running below 30c and my gfx card drivers are up to date. Anyone have any suggestions to resolve this issue?

Sounds like a problem with the graphics card driver. Just because its up to date doesn't mean its bug-free. You could try disabling hardware acceleration in Adobe Flash Player and see if it still crashes on YouTube. Also, if the card is overclocked, it can exhibit odd behavior even if its within accepted heat limits.

"...and everything is running below 30c..."

What sort of cooling system do you have ? Or what is the ambient temperature where you have your PC located ?

when I used speedfan the temp was around 30c for all parts it eventually idled at 40c, and 1900x1200 was the recommended resolution not the one I wanted

I think you need a BIOS update. Check if one is available on the M/B maker's web site.

By the way, you should measure temperatures at least one-half hour after you turn on your computer.

If your computer seems to freeze when you change resolution, that may mean a problem with the gfx card drivers. This problem is known as TDR (timeout detection and recovery) but this phenomenon should also give you a warning message in the system tray: Nvidea display driver stopped responding and has successfully recovered. If you do not see it, you may see it in the EventViewer as a warning. It is nothing to worry about but a nuisance. As drivers mature, it will disappear. So check your eventviewer and advise.
