Vista graphics problem

[wiggyryder]

I just upgraded my HTPC from MCE 2005 to Vista Ultimate x64. Motherboard is a Foxconn 6150BK8MC - nForce430, GeForce 6150 onboard graphics, 2GB ram, Athlon64 4000. The install went well except at first boot when Aero was automatically enabled and the display became all garbled up, almost like the polygons aren't rendering properly. Drivers were updated with most recent 64-bit versions of nForce 15.01 and GeForce 175.19 with no improvements. Everything displays fine in non-aero basic, but I'm still having the same problem when I open media center. Any ideas?

Hmmm. Does it only happen in Aero? Try a 3D game/program and a 2D one, if the program artifacts as well you might have a GPU problem. I remember I burned out my 6600GT a while back on XP and it did something similar while playing games.

That's what I was thinking. It probably overheated when I used it to encode the Olympics in HD. Thanks for your help.

The new GPU based media encoder works on GF6150? I thought it needed an 8xxx series or better.
Anyway also check your BIOS settings to see if there is something like a 'graphics aperture' / video RAM size adjustment and turn that to a higher number.

See if the even newer x64 driver is compatible with the 6xxx series GPUs and if sotry that, 177.x maybe?
I've noticed that if you tell it you have an 6xxx GPU it'll sometimes offer you some old driver to install, whereas if you tell it you have an 8xxx GPU it'll offer you a newer driver BUT the driver release information will say it is compatible with 6xxx, 7xxx, 8xxx, 9xxx....

You could always try NTUNE to see if UNDERCLOCKING the GPU / memory increases stability.
