Built a windows 7 computer, High CPU Usage and Overheating

I built a computer with some friends months ago. That said, I don't know much about computers so they did most of the work.

For the past six months or so I've had problems when playing games on my computer, even though it should (and used to) be able to run them perfectly fine. I first noticed this issue while playing Dota 2. I experienced noticeable frame rate drops, sometimes dropping down to 15 fps instead of what I was used to, a constant 120.
At first I thought it might just be a problem in Dota, but I tried playing Far Cry 3 and CS:GO, and they did not run well. I'm not sure how to describe it, but when I moved the mouse around, the screen would kind of blur and stutter.

I also noticed that, if I looked in Task Manager while playing Dota (which I play much more often than the other two), the CPU usage would sometimes rise to levels I hadn't seen before. I'm talking 75-100%. This does not seem right.
Finally, in OBS (Open Broadcaster Software), red text pops up telling me that my settings are too high for my computer. Before, no such text was there and I was able to stream on Twitch. When I tried recently, I had major fps problems.
I ran Speedfan to check the temperature of my computer and attached the results.

Someone told me to use MiniToolBox and run some tests, which I did (but the output message is SUPER long)
Here's a snapshot thingy that was also requested when I asked for help.

What caused my computer to go from a steady 120 fps to an unstable, spiking fps and an inability to stream in good quality?


P.S. Here are my specs.

Re: Built a windows 7 computer, High CPU Usage and Overheating

Hello bobthebadger53. Is there a possibility that your friends might have overclocked it in any sort? Boosting the graphics card/memory/more internal hardware?

I don't think so. Is there a screen where I can check for that?

Re: Built a windows 7 computer, High CPU Usage and Overheating

Well, usually there is a program involved with overclocking. Some examples include CPU-Z, Prime95, LinX.

The reason that I am asking is that overclocking is primarily used for boosting your computer's internal hardware but if you overclock it too much then you chance burning the motherboard in your computer or experiencing the problems you are dealing with right now.

Did this happen as soon as it was built? I guess what I am asking is has it always been like this?

Re: Built a windows 7 computer, High CPU Usage and Overheating

For about 2 months after I built it, I got great performance from my computer. One day I suddenly started to experience this problem and I could not figure out what changed.

Re: Built a windows 7 computer, High CPU Usage and Overheating

Did you do anything in those two months (visit websites that contained viruses) or downloaded anything that could have potentially caused it?

Not that I can think of. Then again, this started a long time ago so even if I did something to cause it, I don't remember at this point.

Re: Built a windows 7 computer, High CPU Usage and Overheating

Do you have a lot downloaded on your computer? It could be there is very little memory space available at this point which has caused it to slow down.

If this doesn't work then I would try to take it to a professional or call a company. This is something I really can't solve without being able to see it for myself. I would recommend calling some sort of computer company.

There are a lot of things that could be wrong with your computer here.

Sorry I couldn't be more of a help to you.

Re: Built a windows 7 computer, High CPU Usage and Overheating

Ok let's slow down before we start talking about going to a tech shop or whatever, no need to shell out yet, assuming you have the time/patience to deal with it yourself (with our help) and hopefully learn something in the process

So, some things you can try:

1) Make sure Windows, Steam, your games, AV software, etc. are all fully up to date.
2) Boot into Safe Mode (press F8 on boot) and run a FULL virus scan and a full scan with MBAM
3) With your PC turned off at the wall: Open your case, touch the PSU before anything else to ensure you are grounded then have a good look around to see if there is a build up of dust anywhere or if anything looks like it isn't seated properly.
