screen 1/2 sized

[badsnot]

Hello,

I've been referred here by another forum.  
I have a laptop hp pavilionze 5300 w/ ip 4 &
windows xp.  I've had cpu for 2 years and never
a problem.  Today after removing spyware and
unneeded programs (like music things added) my
screen is now half size.
Screen 1/2 sized is perfectly centered and has
black borders in which my mouse icon cannot enter.
Tried monitor size, system settings, etc. Never seen
anything like this before
Please help if possible.

Problem solved.  I went to device manager and was able to remotely open an upgrade.  Upon restart, full screen.
