Just built a new system. Installed the OS ok without any issues. After the system has been on for a while (a couple of mins) weird things start happening to the screen. Not sure if its coincidence but when I installed the Nvidia drivers I started getting funny colours appearing on the screen. I have attached some photo's so you can see what I mean.
Sometimes the computer just freezes and sometimes it recovers with an error message. I have tried running in safe mode and get the same issue and as you can see from the bottom image the funny lines were there even before windows starts.
I hope one of you guys can recommend a place to start looking? Hardware/Software? I have read somewhere about making sure your RAM timings are set correctly but in the BIOS i can only see auto settings and cant relate anything I see to the timings I am farmiliar with?
Incorrect RAM timings will cause random freezes/lockups/bluescreens, I pretty sure unstable RAM wouldn't cause artifacts. This looks like faulty memory on your graphics card or perhaps your powersupply isn't supplying enough power to your graphics card.
Doesn't seem to be a driver issue if your getting these artifacts before entering windows and in safe mode.
Looks like a bad card: Artifacting at the boot screen and Windows logo are usually a sure sign of bad video RAM.
Before you RMA the card do the obvious (unless you already have ): Reseat the memory modules and graphics card and reset the BIOS to factory defaults. If that fails it's time to call up support for an RMA number.
