Windows 7: CPU fan keeps revving up even though i have no intensive programs open

What about the Troubleshooting Steps for Windows 7? It shows how to go over your Win7 with a fine-tooth comb and almost always turns up issues to resolve, shows how to resolve them.

It could also be normal for the CPU, or it could be a lemon that would not do this if you replace it. If it bothers you I'd consider taking it back, or at least consulting the maker's included tech Support as I suggested earlier.

"The CPU fan keeps revving up every few minutes for a couple of seconds and then down again. I only have light applications like microsoft word and firefox open...."

My 18-month old Sony I7 8GB laptop does a similar thing. I can't tell specifically if it's the CPU fan. But some fan revs up when I use my PaleMoon x64 browser to open up multiple tabs. Once most of the tabs are opened completely, the revs are gone. The taskmanager doesn't show anything untoward when it happens. My Norton Internet Security 2013 doesn't warn me of high CPU activity. I don't use any other browser to test if their opening of tabs would do the same.

Without any expertise, in my case, I'm guessing it's a function of security scanning and the nVidia processing of graphical data for the browser. Not knowing any better, I accepted the "cost".

I would uninstall the Norton Bloatware which causes many issues to see what happens with a lightweight AV like Microsoft Security Essentials with the Win7 firewall.

If you still have the original Sony factory preinstall that is a corrupt install to begin with, larded with bloatware and useless duplicate utilties which have better versions built into Win7, throttle Win7's native performance. That's why most tech enthusiasts won't even run such an install but instead Clean Reinstall - Factory OEM Windows 7

Nope. I'd return it for a refund.
New means new means working properly. If it doesn't it shouldn't be the buyer's problem.

My Windows programs will not open images, I can open them with PSP
For a while my windows 7 64 bit would open my images in Documents. Now when I try they appear as a garbled strange format. If I go to PSP ProX2 they open fine. This is a problem for me since I often need to add images to document Newsletters I send out. :confused: Thanks, Char
