I have a 17" dell m6600 laptop with 32gb of ram and an intel i7 2720QM processor. I am having a problem where my computer will often (6-10 times an hour) lock up for 30 to 60 seconds. Sometimes it will continue to work however the mouse will only refresh at like 1 frame a second. Barely usable.
I noticed my cpu usage would often jump to 100% even though no processes were using more than 5 to 10 percent of cpu. Many of these times I was performing simple tasks like web browsing or playing music on spotify.
At first I thought it was thermal throttling, but according to coretemp my cpu is cool. The temperature ranges from 40c to 74c (highest) depending on what tasks I am using my computer for. Every time the computer locks up the cpu has been throttled to 798mhz.
Right now the cpu is throttled down to 798mhz while I write this message and the computer is operating fine. I'm thinking perhaps when the cpu is throttled at some background process kicks in, like windows update or the anti malware service, the computer is overloaded and the cpu doesn't automatically scale up to the appropriate speed?
I am really at a loss of what else the problem could be. I've run memtest overnight and everything is fine.
