General lag (games, mouse, animations) in Windows 8 that JUST started

I have had my PC for two years this month and have had absolutely no problems with it as far as performance. On 2/5 I unplugged external speakers and had to restart the computer to get it to re-recognize them and I have had the problem since (only thing I can think of). After 10-15 minutes after start up everything starts to lag. Not severely, but enough to notice - the start menu is very slow, minimizing and expanding windows is choppy and delayed and my mouse even seems to be a little unresponsive. I play League of Legends several times a day and have never had fps issues but can't play without 20-25 fps. It began after 5 or so minutes ingame. I thought that League was causing the lag somehow but all other games are extremely MORE laggy than League, to the point of not being able to play anything. I repaired the client as well.

There is nothing strange in my registry that I can see, I've turned off unnecessary processes, scanned with antiviruses (CCleaner, avast, malwarebytes) to no avail and reinstalled my graphics card driver. There are no strange process being run in Task Manager at all. I have not done a system restore. I have tried several restarts and my boyfriend cleaned the machine of dust yesterday. No change.

My specs are:
Windows 8 v6.2 (build 9200) 64bit
i5 3350P CPU @ 3.10GHz
8 GB ram

Thanks for any help!

I don't think there's any present danger in using the computer, but I would recommend that you replace your PSU. Hopefully that'll fix your problem, and you can just ignore the faulty temperature reading.

looks like you're using a laptop?

can you run a temperature monitoring software like HWMonitor to see if your laptop is being insufficiently cooled?
can you run a disk health check on your HDD with HDTune to see if the disk is failing (often happens on laptop HDDs due to the physical wear)

I'm using a Radeon 7570 HD. Done a disk check and all are fine, but no, not a laptop. I'll report back with any weird results with a temp monitor.

Looking through Resource Monitor, Chrome and Resource Monitor are the only two processes that are using resources. Everything else seems normal. It doesn't appear that I'm overheated, either. Not sure how to tell what all of this means, so here's a screenshot:

Try a system restore to a restore point earlier than 2/5. Sometime a restore fixes things without you having to track down what's causing the problem.

keep Resource Monitor open, and when you see periods of general lagginess, switch to Resource Monitor to see what is slowing down your system.

Also, you do have one weird temperature reading (TMPIN0) which should not be negative 69 degrees, that is definitely abnormal - a malfunction on your motherboard's temperature sensor at the least.

-edit-
your voltages being shown are completely wrong as well, leading me to suspect your PSU failing, which can throttle your entire system.

The lagginess doesn't come and go it seems, it's constant - watching the Resource Monitor, it only spikes when I have Chrome up. The temp issues are worrying as this PC is refurbished. I also totally forgot to mention it but I was vacuuming on that day and it caused a breaker to pop (happens if vacuuming is running too high on a certain wall...my mistake) and power went out momentarily twice. Computer is connected to surge protector, however. Would you suggest not using the computer until I can replace the PSU? Do you think that is what's causing the issue? Also, the day before my boyfriend cleaned the machine, it was running really loud, which prompted the cleaning. Thanks for the info.
