Clevo p150em - System Interrupts Used 50% of CPU

Earlier today I left my Clevo p150em on while I took a nap so it could finish downloading Battlefield 3. When I woke the laptop up several hours later I noticed the mouse was stuttering around the screen. I took a look at the process manager and it showed that a good 50% of my cpu was used, and almost all of that was due to a process called "System interrupts." Origin and Chrome were the only programs I had open at the time.

I restarted my computer and the problem cleared away, but I'm afraid this could pop up again and potentially cause harm to my laptop. I want to track down the culprit, and Google hasn't been much help. Has anybody else had the same issue on this model, or could somebody take a guess at what it might be? If it's a hardware problem I want to deal with it ASAP.

My basic specs are:
Intel i7 Ivy Bridge 3610qm
ATI HD 7970m
Crucial m4 64bg ssd (Main drive)
500gb 7200rpm HD (DVD Drive)
8gb RAM
%95 NTSC Color gamut full HD screen in matte finish

Interrupts are generated by hardware in the system to get access to the memory so something is misbehaving, without more information it's impossible to say what.

 

Could it be because of peripherals (maybe that's why the mouse pointer was jumping around)? I'd be very happy if my internals weren't acting up.

 

I've run into interrupts before and they really were a freak occurrence in my case. I did what you did and restarted, they popped up again rarely but nothing that I'd consider worthy of dealing with an RMA as long as a restart quickly took care of the problem. If your system is relatively new, I'd contact your reseller and see what they'd advise you on doing but I honestly wouldn't worry too much about it until it pops up again or you see some serious system instability.

 

Yes it could be quite easily.

 

restart the computer once in awhile/more often.

 

Well he said he left it on overnight, not all month, that suggests a rouge device rather than gradual build up.

 

he didn't even say that much but a regularly restarted machine has hiccups like this even more rarely.

 

It sounds like it is regularly restarted, 12 hours of operation without a restart should not have issues like that normally.

 

that he doesn't is just a hunch of mine gleaned from the OP.

 

If you deliberately leave it on while having a nap that sounds like normally he would switch it off when taking a nap or going away for an extended period

 

i can appreciate your ability to draw inferences from between the lines almost as much as my own.

 

I've had a lot of practice over the years
