Nvidia Geforce 6800 GS
AMD Athlon 64 Processor 3200+
Samsung 80gig SATA HD
2Gig Dual memory
17 '' tft Hercules monitor

I have got the above specs but I have a problem when the pc is turned on
first thing in the day..... Everything starts fine, when I get the log on to
windows screen I can log on. But then I get some of the screen showing some
tiny white dotted areas, I can still continue to log on.
Windows start even tho its slow anyway..... when all my icons show on
desktop after a couple of minutes I get columns of the tiny white dots all
across my screen and then the screen goes completely black although pc is
still running so I have to hit the off button to close it down.
When I reboot the pc it runs perfect.

I don't think its the monitor has it was fine until I built this pc which is
about 2 months old and has been doing it since then.. Has its a new pc I
have installed the latest drivers for everything
Any Ideas would be appreciated
