VIA PT880 Screen corruption in Vista

[Aldeia]

same problem here my specs:
C2D E6300
6800 AGP last bios 175.xx
VSTA 775 ASROCK BIOS 3.0
2 GB DDR2

I thought about a HD3850 after update my bios to 3.1
But I don´t know if it safe... My MB only accept 1 GB DDR2 or DDR, 2 slots gone.. :huh:
Don´t know.... if it continues I´ll burn this MB and post on youtube!! :haha:
NVIDIA... :ermm:

My next system will be asus+ATI

EDIT:
I found the dlls that possible are the cause of this sh....!!
I´ve installed this driver http://downloads.guru3d.com/Forceware-Vist...nload-1541.html

That resolved the issue about the resolution (before the maximum was 1280x1024 not the native resolution of my monitor, 1400x900). And how you can see, the problem about horizontal lines disapeared. Ok... after install this driver I rebooted my system and... thats dlls missing just appears on my screen....
I bet that´s the source of all problems on forceware 100.xx :huh:



Does anyone know if the drivers 100.xx updated the version of opengl? I think that´s the problem....

maybe? :ermm:

FYI, there is nothing here that involves VIA. AGP bus drivers as of Vista are developed and provided by Microsoft, just like all other major system bus drivers (PCI, PCI Express, HD Audio, et. al). This change was instituted even earlier for AGP3.0 chipsets, when Microsoft released its Universal AGP (UAGP) Driver with Service Pack 2 for Windows XP.

Its why NVIDIA did not release an AGP driver for NF2 and NF3 under Vista, nor did Intel or SIS for any of their chipsets. No chipset company has developed an AGP driver for Vista because Microsoft would not accept any AGP drivers for WHQL signing or testing, and would not release complete programming specifications for developing AGP drivers under Vista.

If your PCI card didn't work properly, you wouldn't come to VIA for a PCI bus driver because there is no such thing. PCI bus drivers have been Microsoft's responsibility for years and years now. As of Vista, so are AGP bus drivers, so we can safely exclude VIA from the discussion. That leaves ASRock's BIOS, NVIDIA's display drivers, or Microsoft's AGP driver as the only potential culprits.

Since older NVIDIA drivers do not exhibit this problem, while newer NVIDIA drivers introduced this problem, I think we have our answer.

And nothing about nvidia?

Ah, same problem as I have it...

Well, I wrote to the Nvidia Customer Care about this "bug" and some guy there suggested me to report the bug to the QA-Team and I did so. Also included two URLs to forum-topics, one of them this one here. Maybe they can fix it now. :3

sis & uli have same problems with agp & vista, and fix the problem without Microsoft's AGP driver.
nvidia do not fix this problem, because nvidia
termine sales and support simultaneously old products (agp cards, nf2,nf3)
