Programs and files opening very slowly

Starting last night, Google Chrome was taking longer than usual to open webpages. Now under an hour ago, other applications and files take up to 10 seconds to open. My laptop is running fine now because I restarted. I ran CCleaner to clean out my history, cookies, etc. I also ran scans with Microsoft Security Essentials and Malwarebytes, both found nothing. I did not install any software or make any hardware changes. Any ideas?

Run this program and see whether you have any red bars. If yes, there is a driver problem. DPC Latency Checker

There are about 5 or 6 red bars in a row that appear. I went under device manager and they don't show if anything's wrong with any drivers. I also ran a hard drive SMART test using SpeedFan and it shows my HD is fine. As I'm writing, my laptop is working properly. BTW, it's a Toshiba Satellite C655 with Windows 7. I've had it 2 years.

If you have red bars, you have a lot of DPCs (deferred procedure calls). That usually points to a driver problem but can have other causes.

Check in Task Manager or Resource Monitor > CPU tab which processes are interfering.
