Computer freezes, nearly locks up too often (sometimes for even 5 mins)

I have built a gaming PC about half an year ago and everything has been working great, until quite recently I've noticed these weird freezes that I keep getting. Sometimes in a game the whole game would just freeze, but when alt-tabbing out everything would work. Sometimes the whole Windows crashed, and I would get a notification like "Microsoft Windows has crashed. Would you like to end the process" and stuff like that. Once I got that notification the second time, I started to act.

I checked for any kinds of viruses or spyware, mainly anything that could cause any performance issues. I found nothing. After this I just decided to reinstall Windows 7, and so I did, yet, it hasn't really helped. I have two harddrives and an SSD (Kingston 120GB) in my system, as well as a GTX 660 from Asus, XFX 550w 80+ bronze certified PSU, GA-Z87-D3HP mobo, i5-4670k and 8 GB's of ram from Kingston, the HyperX Fury ones. The freezes occur pretty much no matter what I do. For gods sake it even froze while playing Hearthstone. I tried googling my problem and found out that it could be the CPU but I'm not sure. Also to check if it's my two other hdd's, I unplugged them and booted just with the SSD, just to see the freezes appear again.

I also found out something about RMAing stuff but I haven't yet tried any of it, as I don't really have experience of doing stuff like that.

Any help is appreciated.

Yeah the lag while dragging is because since it's loading default drivers it won't do it as smoothly as when having the appropriate video drivers installed, so yes, it seems like the problem is your SSD.

You'll have to look around as for how to deal with it, I haven't used an SSD yet but read that chkdsk is actually "harmful" for a SSD due to the limited write/read sequences it has or something like that, so look for info regarding how to fix an SSD at software level.


EDIT: One more thing to check actually, there's the possibility that some service(s) installed in your OS is the culprit of your problem, boot with your SSD and monitor CPU/RAM usage at idle, CPU shouldn't go over 10% usage total (shouldn't get over 4% actually).

At idle the CPU is around 30 degrees Celsius while stress testing it with OCCT makes it go 60-70 between all the cores, and the voltage was 1,18V at maximum if I'm reading this correctly (could be wrong since I haven't really experienced much with voltages before). The GPU on the other hand is about 35-45 degrees Celsius at idle and about just under 80 max degrees when stressing it.

At first I actually did notice it freeze for about 5-10 seconds but I didn't run it for long enough, 5 minutes at best. I can stress it more today, for how long should I stress it for? An hour?

Yeah at least one hour, better if you can do it for like 4 hours though, in any case it doesn't seem to be the CPU, at such load it should have caused a freeze that would've locked up the entire pc, but test it longer anyways just to be sure.

Usually that problem is caused by virus/malware which you've ruled out by now, overheating, CPU failure or a failing HDD/SSD.

A less common cause it's an anormal DPC (deferred procedure call) or Interrupts calls that aren't caused by the CPU, these situations are hard to evaluate but they are caused by some failing hardware device like network interface or sound card etc. We'll try to evaluate that after discarding all other possibilities.

Alright well, doing it for little over an hour showed the exact same temps ranging from 61-70 degrees celsius between all the cores. Actually as I'm looking at the stats and opening a new tab in chrome, this all froze just now for little over a sec and Spotify almost crashed. Here's some pics of the stats I got.

As I have no idea about those voltages, as I stated earlier, I just posted most of them. I really should know better.

I'm starting to wonder if it's the SSD, as you said it could be the cause. After all I did unplug my HDD's and it still froze so.

E: Oh and I only included one core since the rest of them show the same numbers.

Well CPU seems ok..... in order to rule out your SSD you could boot with no HDD nor SSD connected to your system using a Live CD OS like Ubuntu, if there are no hiccups while using it you'll know your SSD is the culprit (since you've already tried without your HDDs right?).

I will try that now. And yeah I've already tried booting without the HDDs. Just now however I got two BSOD's, one when I was watching Netflix and another when I logged in. The first one appeared for 0.5 secs and then the screen went totally black. Then, it restarted itself. I have no idea what's the matter of this computer.

A little update: Booting to Ubuntu seems to be working flawlessly, apart from a little lagging while dragging the windows but I don't know if that's supposed to happen. I mean like when dragging a window and moving it around, in Windows and OS X it's totally smooth but in Ubuntu it seemed a bit laggy. But yeah works good. So is it the SSD then?

I am terribly sorry, I thought I had already answered to this. I really appreciate all your effort on this. I will check how to fix the SSD on a software level. Maybe updating some drivers will do, hopefully. The CPU usage wasn't the culprit either as the usage didn't exceed 2% after booting up. Thank you for everything.
