PLEASE ASSIST ME-- Computer Not Starting Propery

[overrated911]

I have an XP Home Edition and recently it has given me a probelm.
When the computer starts up everything is fine then is asks me how I wish to start up the computer giving me these options;
Safe Mode <-- works, but with a zoomed in screen.
Safe Mode with Command Promt <-- Same thing.
Safe Mode with Networking <-- Same thing.
Last Used Configuration Settings <-- Windows Logo appears then screen goes black.
Start Up Windows Normally <-- Same thing as L U C S

And on rare occasions the computer will start up normally without issue. Not very often.

DId you install/run any new program before this started?

Safe Mode <-- works, but with a zoomed in screen.

Safe mode is suppoed to be like that. Boot into Safe Mode and look at the following link to system restore.

Restore to about 2 days before the problem occured. You will not lose any work.
