I have a Sony Vaio Laptop, PCG-K33. 512MB RAM, P4:3.06 GHz, 60 GB HD. My CPU usage goes to 100% within minutes of playing a DVD or an AVI file...These days it goes 100% even when I am just using MS Word or yahoo messenger.
My drives are highly defragmented(using disk keeper, Healthy)...there is about 50% free space on my C drive...I regularly run Lavasoft, Registry Mehanic and have used Cleanup, CWshredder, EWido, SPyBot, Trojan Hunter before posting here. My Windows software is as updated as possible.
Can you please tell me what is the issue with my laptop? And please help me fix it!
