High CPU usage after waking up - iastor.sys issue
Hi
I'm running Windows 7 x64 on my ASUS laptop
It works very well , until I have it Sleep . A few minutes after waking up , I realize that the CPU usage reaches 9x-100% , caused by SYSTEM process (2x-30%) , which makes me almost unable to work on it .
I used Process Explorer to explore the process and found out the iastor.sys (resides in C:/Windows/System32/Drivers) that causes the trouble . It consumes >20% CPU while others 0.0x %
Unfortunately I can't take a screenshot , but I believe that's clear enough
I'm thinking of downloading another iastor.sys file and replacing my current one , but I'm not sure it can solve .
Can anyone help me with this issue ? Thanks a lot .
