hmm, this is weird but well it's not the first time i hear about things like this, but it's a original Windows 7 Ultimate SP1 64bit is it a modded version of Windows 7 og does it have integrated Service Pack 1 or how is it?

i know Lenovo mod their Windows 7 so there are problems with some of the updates on Windows update and other bugs i have seen.

Clean MSDN SP1 integrated copy of Windows 7 64-bit Ultimate, I think. No OS mods, not a laptop. All updates installed.

oki, i use the version from digitalriver and i tried both Professional and Ultimate and i never had a problem with the Cuda not showing, that was why i asked, but well i always disable UAC and "Run as Administrator" so maybe that's why i never had this kinda problem

No, you did not have this problem, because it is random/intermittent and happens once in 200 (maybe 1000) tries!
I don't think UAC has anything to do with this.
It is also possible that the problem was only happening with a certain/older version of the GeForce drivers. I am using 320.18 WHQL drivers right now.
Another possible reason is a conflict with other GPU-using software, for example Folding@Home (which I use) or a video player/video converter software.

Ok so i had the same problem with GPU-Z not showing CUDA, to solve this problem is very simple, i got Virtu-MVP installed, if its started when i power on gpu-z i have cuda off, if i turn off Virtu MVP and start gpu-z again the cuda is active so in my case this is the problem. Hope it helps

Nope. Does not help. My mobo does support Virtu, but Virtu software is currently NOT installed.
Thanks for the comment anyway!
