Well here's the Problem I get
Intermittant Power Connection Failure Messages
& Intermittant Pixel breakups...

I have tried swapping out the Graphic Card for One the same but no change...

The Bios on the Mobo was flashed a while back to bring it up to the 2GB RAM Spec..
I seem to think that it was around then that this problem started.. and then agin maybe not...
Tried using various Nvidia Driver sets.. etc etc. so i can out-rule driver problems

Hopefully some one will respond, having seen this issue before..

PS i forgot to mention the supply to the card is on its own branch and I've tried various combinations and free connections, cant remember the output from the PSU ( its a M8's PC ) but i know that it is a high spec one , around 500w...

Smokey if ya see this i'm sure you'll put me right....

Thanx muchly in advance.....
