nc6400 with T7200 2.0Ghz. Running very slow. test with CPU-Z

Hi!

I got a Hp nc6400 Laptop with a Intel duo T7200 processor.. A couple of weeks ago it started running very very slow.. The task manager showed that the CPU was working 100% and explorer being the one that took the most CPU. So i thought it was a virus or a trojan, so i ran spybot, trojan remover, Nod 32, and adaware.. i found some spyware and trojans and removed them sucsessfully but the problem remained.

So i desided to reinstall xp and format the whole harddrive. I did this..but still it was running very very slow. So now i installed windows vista. and after a good 5 hours (!) it was done. But it is still running slow. Vista rated the processor 1,1 witch should indicate some problem.

I have changed the power settins to maximum performance, and still it doesnt work.

I also noticed that HP batterycheck says that the cells on my battery is broken and that it needs to be replaced, but when i put the same battery in my other laptop (nx6320) it says the battery is fine!..


Please help me!!

It could be a broken bios, or a faulty mobo.. Try flashing to the latest BIOS again.. CPUs rarely die like this...

Try running benchmarks like SuperPi, WPrime.. Also, check to see if the voltages, multipliers aren't set wrongly.. Also, check if SpeedStep is disabled in the BIOS.. because then it locks to the slowest frequency..

 

Its overheating, causing it downclock.

Download HWmonitor and post back with your temps.
