Well, here's how it goes. I launch up my computer and it works just fine for about an hour. After that, it starts spiking out of nowhere, even when no application is running. (Mouse stops moving.) What it does is it goes from 2% of my CPU usage to 100% in that time period, and then goes back down to 2%. Is there anything that can cause this? I didn't download anything in the past 2 months, and my antivirus (Kaspersky) doesn't see anything. I'm seriously lost. If there are any previous cases of this on the forums, I couldn't find them, but if there's a solved one, I'd love a link to it.
Nearly lethal CPU spikes

Not sure there's a way to help. Case is solved, I guess. Go to the full post »

Process Explorer will tell you what is using up the CPU resources when you get these spikes, download and use it now to familiarise yourself with it and that will make it easier to use when the time comes to try an identify the cause of the spikes;
Download Process Explorer which you can obtain from here
Save it to your desktop then run it (Vista or Win7 - right click and Run as Administrator).
View, Select Column, check Verified Signer, OK
Options, Verify Image Signatures.
Click twice on the CPU column header to arrange things by CPU usage, this will put the services with the highest CPU usage at the top of the log.
Wait a minimum of a minute then grab a screenshot and attach it to your next reply for us
To capture and post a screenshot;
Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... Click on the More Reply Options tab then after typing in any response you have... click on Choose File...desktop...find the screenshot..select it and click on Attach This File...on the lower left...after it says upload successful...click on add reply like you normally would.
Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

The readings above are very good, the higher the System Idle Process figure the better.

Small update: I've been repeating everything that I did step by step every single day when the spikes happened, and they don't happen anymore. Trying to find out what fixed it, because it sure wasn't me.

A couple things could cause it.
Your virus scanner is running a scan, a program is doing an update or windows could be downloading and installing some updates to name a few.
Keep an eye on it and grab a screen shot of process explorer if it happens again.

I've checked for these when it happened, and it wasn't it. It happened even when I had my antivirus off and updates disabled.

One of life's mysteries perhaps
At least you now have the means to quickly check what is causing the problem should it happen again.
I would give it at least a week trouble free before considering the issue resolved btw.

Nothing shown to be maxing out the processor there Kekmaster.
What told you that the processor was spiking.

I probably should've captured the graph too. Looked like monster teeth. My mistake, I'll do it next time.

I probably should've captured the graph too.
Aye that is the point of running Process Explorer
Looked like monster teeth.
Sounds a bit scary
My mistake, I'll do it next time.
No worries, them monster teeth probably spooked you

Got there too late to take a picture, spikes seemed to be showing on task manager but not on processexplorer, just gonna show both of the things that show the leftovers of the spikes. I'm really not sure what's causing this, but yeah.
Edit: There it is again. I'm trying to snip a good picture of the graph and I can't get the surroundings. Incredible.

Doesn`t help any Im afraid as such spikes will occur even when you click on a desktop icon etc, I`m having no such problems as what you report but look at my notebook screenshot when only running PE;

The computer wouldn't freeze for 5-10 seconds and repeat a sound played at the same second almost making it sound like an "mlg" video just from me sitting there and watching youtube.
