Installed the full release version of ie9 on my pc yesterday. Ever since then my monitor resolution will only offer me 640x480 @60 hz. Col. It only offers me 32 bit for colours also.

My graphics card is an ATI Radeon hd 5570 and I have tried installing the latest drivers for that, but to no avail.

This is driving me bonkers, can anyone help.

Oh by the way I'm running Windows Vista Ultimate 32 - Bit



Thanks

Sounds like a bad install. Lets test with another broswer; try Firefox or Chrome. If it works, I think that you should use that browser.
If it does not work, go to search and type Turn windows features turn on or off,
turn off IE.
If that does not work, uninstall and try. If it works, keep it uninstalled or try to install again, and see what happens.
