Start UP problem

After reformatting my computer and getting rid of every illegal software downloaded.

Installed
Avast
Malwarebytes
Sybot
Spywareblaster
Roguekiller
Hitman PRO
Personal Firewall

My computer start up loads like hell. it takes more than a minute to load and after loading CPU usage is more than 80%

After installing roguekiller and hitman pro this is where i notice my start up loads like hell..

Is there any similar issue regarding this?

 

I already found out the problem.

My Fake OS is causing all the problems. When i run the rogue killer tool it deletes something on the system that when i restart it almost crashes the whole OS, im not sure about this but i think this is the nearest reason.

I am not actually fan of pirated softwares. But This is all that i can have. This is the only software that is illegal on my system, the rest are free/open source or shareware.

Is there anyway that i can get a genuine xp installer for free? I heard that linux is free but i already tried linux and i find it not user friendly, im having hard time using it.
