Windows 7: Windows 7 Suddenly Slow with Low CPU Usage

Windows 7 Suddenly Slow with Low CPU Usage

Hello,
I recently installed Windows Live Essentials 2012 on my desktop computer, this was 2 days ago. After I had restarted my computer I noticed everything had slowed down drastically. Programs that I before could open in a few seconds took up to an hour to run. At first I thought it was Live Essentials that was causing this so I unistalled all of it's programs. This seemed to solve the problem for a while, but the next day my computer was slow again, just like it was when before.

I checked task manager, and my CPU remains at 0 - 5% as normal. Physical memory is at 21% currently. The LED light showing the disk drive symbol is on constantly. Every few seconds it will flicker and I can hear that disk drive working sound. If I am moving my cursor when this happens it will freeze for a moment.

So far I have tried doing a system restore in safe mode (I got the error saying system restore did not complete successfully when I tried out of safe mode) and defragmenting my disk drive. Neither have made a difference. If anyone could shed some light on what I should do that would be a great help.

Have a look what's going on with your disk - use Resource Monitor > Disk tab

Ok, I have the resource monitor open, I don't see anything out of the ordinary other than the spikes.

Hmm, there is indeed not much going on. Maybe you caught it at the wrong time. If your control light flickers all the time, there must be some more disk activity.

If the CPU does nothing and the disk does nothing, it is hard to say what could be slowing your system. Maybe there is a disk problem of some sort. Suggest you run chkdisk C: /r in command prompt. Maybe that yields something.

Looks like I've spoken too soon. My computer has suddenly started running slow again. Should I try running chkdsk again or is there something else I can do?

It will not hurt to run a second chkdsk. But if this persisit, there may be something wrong with yout disk. Do you have a second physical disk in this sytem.
