What?!


My son wants to sell his laptop online. I know that there are ways to retrieve info even after you clean the cache, run crap cleaner, etc..
Is there something he should do to ensure that his personal info isn't jeopardized before he sells it?



Answer
Sorry formatting wont help. Don't sell the Hard Disk unless he has Demagnetized it. Sell the balance.

how do you make your computer better with the gaming graphics without going to buy an actual gaming card?

My computer info:
Windows 7 Home Premium
Packard Bell: imedia s3720
Intel(R) Celeron (R) CPU E3200 @ 2.40GHz
2.00 GB RAM
64-BIT Operating System

I want to use my computer for gaming as well as doing general stuff on the computer.



Answer
Quite simply, you don't. The built in video cards that come on most motherboards are really low end. They use shared memory, which is really slow, and they don't have very good Direct3D or OpenGL support. If you want decent gaming performance, you pretty much have to install an external video card.
