Standard VGA Graphics Adapter (Code 10)

A few months ago I wiped and reloaded my computer because it had a virus on it and it seemed like the easier thing to do. When I reloaded everything the screen became more stretched and there is a yellow exclamation point next the the Standard VGA Graphics Adapter in device manager.
Specs:
Dell 1525
Intel174 Core153; 2 Duo T6500 (2.10GHz/800Mhz FSB/2MB cache)
2GB Shared Dual Channel DDR2 at 800MHz
15.6 inch display (1366X768)
Intel Graphics Media Accelerator X4500HD
160 GB SATA Hard drive (5400RPM)
Windows Vista Home Premium Edition SP1 32 Bit
Integrated 10/100 Network Card
Dell Wireless 1397 802.11g Half Mini-Card

So I've checked the Dell Support website and downloaded all the Video drivers and nothing worked. I'm not sure what to do.

driver not installed correctly/wrong driver. uninstall the drivers from programs and features and then remove the video adaptor from device manager, reboot to safe mode and then use a driver cleaner to remove the leftover drivers. then do a clean boot so no apps can not interfere and reinstall the driver package.
