I am an above average computer user and gamer. I built my own computer in October and everything has worked flawlessly from October-February.

Recently my computer has started freezing. First there is a brief pause, followed by some lag, and then everything freezes for about 10-20 seconds. After the freeze everything works perfectly again. After watching the task manager during the freeze, I've noticed two different scenarios. Right before the computer freezes, the % of processor used goes to 100% or more commonly 0%.

I have an Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor.

Here are a few examples of what is going on, taken right after the computer unfreezes.

Software, Hardware, Bios, Chipset, Overheating?

I have tried reformatting and nothing changed. There are no common programs open and running at the time the computer freezes.

Any help/suggestions would be appreciated,
Thanks.

I don't understand. Is it 100%, or 0%?
If you look at CPU usage in Task Manager can you identify, which process is the main CPU user?

Download, and install SpeedFan: http://www.almico.com/sfdownload.php

Provide processor info (hold Windows logo key, and hit Pause/Break key to find out).

That's what doesn't make sense to me. Sometimes it spikes to 100% like some of the first screenshots, and sometimes it falls to 0% like in the two above.

Nothing out of the ordinary while the computer is stable. I'll watch what happens with the temperatures when the computer freezes. I just assumed it probably wasn't overheating because it seems like it'd have done it in the first 5 months as well, but we'll see.

I apologize for not being clear here. I wanted you to click on "Processes" tab and there watch "CPU" column.

That's it, plus watch that "CPU" column at the same time.

Are you doing anything in particular, when computer freezes?

That's the first thing I did when it started happening. Nothing unusual there and they remain consistent before/during/after it freezes.

Nothing particular. Quite a bit of the time I'm playing a high graphic demanding game, but it has occurred several other times with just a browser open or chat program.

The computer didn't freeze or twitch, but I noticed the temps get quite warm. Right when they got up there, I could hear the fan speed up until it cooled down.

Is that normal or should the fans be preventing the temps from ever getting that high in the first place?

It doesn't look good. What programs are you running at the moment?

Pretty fair.

You may try to run some "heating up" program, like video conversion, or video burning and see how the temps are.

Yes I do.

This is getting more and more annoying. I wish I could at least figure out what the problem is. After running that CPU heat temp I've noticed it gets quite hot at times, but it seems to be a deception. When it brings up the fire icon, the temp is only a couple of degrees over the normal temp and right when it gets that warm, I can hear the fans RPMs speed up.
