Hi guys,

I have a strange problem (I have actually registered hete to post it): My NVidia 250 GTS is sometimes not recognised by my computer.
I've tried:
- Cleaning, replugging cables, checking everything...
- checking my screen + cable. Nothing wrong.
- videocard in another computer, 3 day boot sequence and benchmarks, all green light.
- another PSU, not the problem.
- updating BIOS, not the problem.
- reinstalling + updating drivers.

Right now I'm on my onboard graphics card, which always works when my videocard doesnt. Once in a while, my videocard gives output, and I haven't been able to spot any pattern when it's doing so...

My rig:
Intel Quad core Q6600, 4 GB RAM
NVidia GeForce 250 GTS, 256 MB
650 GB HDD, Windows 7 32bit + Ubuntu 10.10 dual-boot

Please respond, I'm out of options...

Thanks in advance,
Hidde

Sounds like you need to return or replace the 250GTS. I think you pretty much diagnosed the problem yourself. Good luck!

Hi,

I actually did that, and they checked it: three day boot sequence with benchmark tests, no problems found.
That is the problem, the videocard is fine, but something else is wrong.

Thanks,

That only leaves a problem with the motherboard, in particular with the PCI-E x16 slot. Have you tried another PCI-E GPU in the same slot to see how it reacts?
