Just because windoze is dead, doesnt meant he laptop is bad 
Format and re-image that bitch, good as new if the drive is physically OK.
And yes, I would use any form of Linux over WIN.
Reformat the hard drive. Re-install Win7. Put in free AntiVirus like Avira and/or Malwarebytes Anti-Malware.

Assuming your laptop hardware are fine, it should be good as new.
you need a reliable firewall, a good anti-virus/anti-malware program and you are set.
On my old PC, i had Zone Alarm, AntiVir and Adaware and never had any problems. If you are not sure what you are doing, have the strictest setting and from there start to allow single processes and programs. The more programs you have running in the background that have internet access, the easier you fall into a trap.
Weekly full scans of the PC do the rest.
A PC is like a car, you cannot expect it to run smoothly if you never have an oil check, add some air for the tires and so on.
Deicide,
Do what these guys say. If it's your hardware that's bad, and if it's a gaming laptop you want, then buy this:
