Vista - Help anyone?!

My computer has been acting weird. In my admin account I log in and abut 10 seconds later the resolution ges low making everything look huge. In my other 2 guest accounts there is no problem. How can I fix this? I've tried changing resolution while i'm on the account but that's only temporary, when i restart the computer it's the same thing over again and all of my drivers are updated and i cant roll back any of them either ..oh and i also cant restore any previous system restore points cause well my computer doesnt have any.....
sooooo any help would be greatttly appreciated as to how to fix this!!
thanks

Add/remove your video drivers. Get a driver cleaner and remove all Nvidia and ATI video drivers. Restart. Reinstall the correct video driver and monitor.inf file.

Umm yeh i'm not computer savvy at all..so i wouldnt know how to go about doing that... any step by step help would be appreciated though!

Hi Nafisa,

1) Go to the card manufacturers and download the correct drivers. If you have an nvidia graphics card, it's here

Drivers - Download NVIDIA Drivers

2) Remove the old drivers. Go to device manager ( Control Panel>Classic View, double click Device Manager ).

Click the cross next to Display Adapters, double click your graphics card, click Driver tab, and click the Uninstall button.

3) Next (Optional - I have not needed to do this - try steps 1,2 and 4 first - if that doesn't work, you might try this ) Download and install a driver cleaner, and follow the instructions - there is one here
Guru3D - Driver Sweeper

4 ) Then Restart your computer. Install the new driver you downloaded - just right click it and run as admin - will probably ask you to restart again.

Hope that helps
