System Interrupts

[sickofit]

Hi!
I have an hp pavillion dv6 1245dx core 2 duo 2.1 with 3 gb ram. It comes with windows Vista but i installed windows 7 and it was working fine. After a virus attack i re installed the windows and it works fine for around 30 mins but after that cpu usage goes to 100%. I have installed al the drivers available for my laptop from hp website. It has a realtek graphics card. I am literally sick of it please help me out here guys. I am dying to get rid of this problem

Open up start menu and write "resmon" without the " and go to CPU tab and sort by average CPU, you'll see which process is using the most CPU power, now when you go to task manager (taskmgr on start menu) and you can find the process there, right click on it and choose "open file location" which gives some hint about what program that is, if the process name itself doesn't.

Post back here what you find.

edit: also this is graphic cards forum, your problem has to do with CPU.

Well you could try first downloading drivers from http://downloadcenter.intel.com/download.aspx?url=/19130/a08/Win7Vista15177.exe&DwnldId=19130〈=eng

and take a look if How to get the cause of high CPU usage by DPC / Interrupt - MSFN Forums helps, that's pretty much all I can do right now.

it was due to system over heating apparently
