Need help repairing computer, crashing after start up

I have an hp laptop G62 series 64 bit windows 7. I can run it in safe mode only; in normal mode it loads the desktop but after a minute or two it freezes. My battery needs replacing i think but i don't know if that is the problem. I ran a malware check and deleted the corrupted files and it had no effect. If anyone can help me please do so.

Maybe this tutorial will help.

I followed the guide and i was able to log in but how do I restore the features

In step two, where you selected to "Disable All".
You should go back to that step
enable one or two at a time
restart and see what happens
repeat until you find the problem.

Or you can try half splitting.
