high resolution not working on card(s)

[Tedster]

I have an MSI K7N2 Delta2 MB with 3 sticks of 512MB memory PC 3200

I'm running a maddog FX 5500 card that in higher resolutions the graphics are scrambled.

I swapped the card with an ATI 9200 card and got the same problem.

This problem cropped up recently - it was working fine at first.

The maddog card is back in. I have had the MB replaced and still the same problem.
I'm running Win XP pro. I have run out of options... I think it is driver related.

I cannot see high resolution graphics on internet web pages (like pictures on a web page)

It's getting really annoying... I can't figure it out. I have even reloaded windows onto the hard drive and started from scratch and still have the same problems.

Can anybody help? Both graphics cards are new.

How high is high?

 

[Tedster]

anything above 1162x864. The problem is most noticable with the regular XP wallpaper. I have yellow blocks scattered around. When I open up explorer, any photos on a web page are totally scrambled. Mozilla won't even load.

Does your monitor support the higher resoultion you are trying to use ?

The monitor works fine. I have used it on my old system with much higher resolutions. I have RMA'ed the card back to the manufacturer. I had already RMA'ed the motherboard and the replacement MB gave me the same problem. Since all the drivers are current, I have no other alternative except to assume the card is faulty.
