Windows 7: CPU Usage instantly goes 100 percent an freezes the system

Windows 7 Ultimate 64bit
CPU Usage instantly goes 100 percent an freezes the system

Hi everyone.

I am using HP ProBook 4520s Core i3 M370 3GB RAM, 320 HD and Windows 7 ultimate 64bit. Just received it from my dad 3 days ago, and decided to tune it my way as i've recently started a programming carrier. I Formatted it, installed ATI graphic driver (as it came originally with its system), JDK, wamp and office 2010 from Microsoft. As i was watching a movie last nigh, all of sudden it went frozen displaying video like a scratched DVD disk (I wondered why!!!) it took minutes, then i decided to have a look at my CPU performance, surprisingly it was 100percent busy. I unplugged the charger and waited for awhile and it then dropped to its normal usage... It kept doing so for several times. I then decided to google but for a dead end. i finally decided to format the machine again, afterwards i re-installed JDK, ATI video driver and wamp, that was all. i went through my testing again (watching a 720p movie) it then happened the same (CPU went 100percent). Uninstalled ATI, the problem persist... I don't know what is happening now. Please help me

I did, even used the process explorer. All i can see is "system idle process" which consumes 96-99% of the processor, some they say it to no be a virus. I formatted twice, but the problem still persist.

Hi, to confirm is this DVD you watching or a *.avi file or something from the web? Have you tried using alternative media players/browser (like VCL/Chrome), also try installing K-Lite Codec pack if it's files like *.avi that you are watching (Download K-Lite Codec Pack 11.05 (Full) -
