Windows 7: High CPU Usage Problem

High CPU Usage Problem

Laptop specs

System Model: HP Pavilion Dv7 Notebook PC
Processor: Intel Core i5 @ 2.53 GHz, 2 Cores, 4 Logic Processors

My laptop is about 4 months old, and I began having this problem 2 months ago. My CPU power rises up to 100% and gets stuck there, and the system slows down to a crawl. I can only fix it temporarily by doing System Restore in Safe Mode (stopped working in Normal Mode). At first, the issue occurred rarely, and I was fine with doing System Restore a couple times. But now, it's suddenly happening very frequently, like every two or three days, sometimes twice in one day. I don't play PC games, and I use about 30%-40% of my RAM on average. Typical programs I use are Firefox, Skype, Gimp, and Rainmeter.

It happens when I'm plugged in and using HP Recommended power plan, and when I'm in power saver mode. However, it seems to be triggered more by power saver mode. In fact, I just selected that, and CPU went up to 100% again. But it doesn't usually return back down to normal if I select HP Recommended...and again, it happens when I've always been using that setting too.

I've run full virus scan (Kapersky), and a malware scan, and did little things to optimize computer performance, but nothing has been detected. Is it possible that this is a problem with the Registry or something?

I think I might have solved my problem, don't know...

After doing a little more research, I realized that this was happening to a lot of people while they're in power saver mode. Solution: Activate System cooling policy. I had it on Passive the whole time.

When I select Power Saver Mode now, the problem isn't occurring instantly, but I'll have to give my laptop a couple days before I can be sure it won't do it after a few minutes or hours (like it usually does). But I still don't get why this happens when I'm using HP Recommended Power Plan. The System cooling policy has always been active under that setting, so why the same issues as if I was in power saver? Anyway, I dunno if that will particularly be fixed...

Check and make sure you have the latest BIOS for your laptop. I know on my DV7 it had an update to help work with Windows 7, but mine was an AMD chip. Still wont hurt to take a look.

I also had a similar problem like this, but it seems ^this 'kind of' solved the problem. 'Kind of' because, when I look on the Task Manager on Power Saver mode, CPU Usage 'spikes' to 50% and back to 1% every 25 seconds or so. Oh well, at least I can finally save battery now, thanks TigerBunny
