Well, maybe you should consider buying the full version so that we could actually help you. Assisting people who have pirated copies of software is against the rules here. If you can't afford a copy of Windows, then there's always Linux.
So heres the situation im running the windows 7 trial version modded a little so it doesnt shut off every 2 hours. I have that little gadget that tells you how much of the cpu is being used. Every time i turn on the computer the cpu usage spikes to 100 percent and stays there for approximately 10 minutes. After that it stays at 0-5 percent but as soon as i click anything even google chrome or control panel its goes back to 100 my computer is ridiculously slow whats the problem and how do i fix it? Im pretty sure i dont have any viruses because i have AVG and ccleaner so im not sure what to do. Thanks for the help
