I have a strange problem, I haven't been able to solve, even with quite some knowledge of videocards, and computers.
I have an nVidia 250 GTS, purchased a year ago (all new, no second-hand). Everything worked very well, until about a month ago. Sometimes, when I power on my computer, there is just NO output to my monitor. If this happens, the videocard does get power, the fan does start spinning for a while, but my screen stays idle. Also, if this happens, it is always when I power on my computer, NEVER while it is on.
I have the correct drivers installed, both Windows 7 and Linux (Ubuntu 10.10) don't want to show...
My onboard VGA worked perfectly, everything as well, just sometimes the videocard. Sometimes it suddenly works again, that's the strange part. I don't know what goes wrong, so I can't repair it...
For the last two days, there has been no output at all, I'm all on my onboard VGA now.
Processor: Intel Core 2 Quad Q6600 (Kenfield) @ 2.40 GHz

PSU: 550W, recently bought.

Anyone has any solutions?
