Maybe you just wasn't paying attention. But if the computer is not slowing down or having problems. Don't try and make a problem out of nothing. Its just a waste of time.

It is probably Superfetch kicking in loading frequently used programs into memory in the background, which is nothing to be concerned about. It does that upon waking from hibernate if my memory serves me. If you want to test my hypothesis, disable the superfetch service and see if it still happens. The re-enable it in automatic mode after you have tested.

i am sorry logicearth, but i beg to differ of you
i know this is nothing more than a little and harmless annoyance but, i am 100% sure it did not do it before

i'll try tomorow but... i was reading about superfetch to know more about it and to have it clear enought to understand somethings like this:

i have couple of days wth new ram upgrade, i read that the more ram i have, the more superfetch works, in order to take advantage of the ram increase, since HDD's speed is slower than ram, superfetch came up to manage apps store in ram.. thats what i understood...

so... i'll try disabling superfetch tomorow and ill post results.

thanks guys!

If you say so. But once you start trying to poke a phantom problem you'll just end up creating a real problem.

Hmm, hard to tell which function is really triggering it. Here are a few ideas from other people that had the same problem: Windows 7 - svchost high cpu usage. - Super User

Btw: When you right click on any of those processes - e.g. the svchost.exe we are talking about, you can go to the internet for more info.

imm.. im not sure, but i do think that should be the way to drive the "problem" since there is no CPU usage...

Ok, i did it, i disable Superfetch -> tried hibernating -> wake up = done, when the desktop come up, the HDD led stops, only the power led is on, pretty serene!

now, i have read what superfetch does, and have sense, since i have upgrade to 2gb the last week (exactly the time i notice i've been having the issue) but all seems working fine.. what should i do with superfetch? advantages or disadvantages of having it enabled or disabled...?

Unless you are using a Solid State Drive, Superfetch should be enabled. It keeps program bits and often accessed files in memory. This allows your PC to run and open your programs quicker.

Like I said, re-enable it and set it to automatic mode. It will speed up loading of your frequently accessed programs.

At least now you know what it is and that it is normal and good!
