Screen resolution wrong & Aero theme isn't working

[LizaInfante]

Hello there,

For some reason, After I've reformatted my computer it's changed the size of the screen.
The default size is now; 1280x1024
When before it was: 1920x1080

Also my Aero themes aren't working.
It's saying my video card doesn't support Aero Effects.
When before it did.

Could someone possibly tell me the fix please?
Thanks in advance!

We need to know what graphics card you use. It seems that the graphics card driver is not installed. If you can tell us the card you use we can find you the correct driver.
