Hi everyone,
It's about 2 months now that my laptop (hp probook 4520s, 6 gb of ram intel i5 2,53 GHrz) become slow for no apparent reasons.
Since the problem started i had to replace the HD and reinstall windows (switched from 7 to 8.1) and i hopped the problem would solve with a clean install...but after some time (1 month since clean install) the problem came back again.
After some up time (could be 30 mins as 5 hours) the laptop slows down drastically, I open tskmngr and gives me 47% cpu usage using 1,19 GHrz of CPU, 2.5 gb of ram in use. If I try to identify the responsable process I sometime get Service system, but it can vary, and no additional clue.
Don't have a clue why this happens so here I am.
I used WPR to register 2 mins of the problem and have a .etl file, but don't know what to do with it.
Please help
