Laptop slows down and CPU runs a lot after sleeping

[steamtechie]

Hi there,
I have a Dell D820 with Windows 7 x32. Over the past couple of weeks it's developed a problem where if the laptop is used for a couple hours, or if it goes to sleep and I wake it back up, the CPU usage rate will go up quite a bit, often maxing out, and the computer will slow down. Often restarting the laptop will solve the problem for a little while, but sometimes it won't and it'll take a long time and several hard restarts to start back up.

I've scanned it with Malwarebytes and AVG, and neither found anything bad on the computer. According to the disk defragmenter the disk isn't too fragmented. I've looked at the process list in the task manager when the CPU is maxed out, and nothing too out of the ordinary appears, at least to my layman's eye. I was going to do a system restore, but the oldest restore point is a few days ago and the problem's been going on for several weeks, so I doubt that would help.

Thanks a lot in advance for your help.

Dan could we get your system specs so we know what hardware we are dealing with?


Could be RAM, paging file, ready boost, etc.

Hi there,
I took a screenshot of the specs. Here you go.

Thanks,

When this high CPU usage happens. Open task manager, and see if any processes are using large percentage of CPU. A Guy
