Hello, I have a weird computer problem and I need help and tips how to diagnose what exactly is wrong and possibly fix.

So a few months ago I was cleaning my computer, and I have never really cleaned a computer before and I am not really an expert when it comes to computers especially hardware, so I removed my cpu and when everything was cleaned I wanted to put it back but then I didn't know how to put it back so I asked my dad and he was saying something about it wont go back, I am sure if I wanted to I could of taken off the cooler and stuff but oh well its in the past...

So now my tower didn't have a CPU anymore, and I didn't had the money or the energy to fix it at that time, so it was standing there unused for a couple of months (I think 2-3 months or so) I opened the case a few times to check mobo and stuff, but I always use antistatic bracelet when touching stuff.

A few months later I bought a new CPU, AMD FX 8, same socket as I had before, installing it went smooth, after a while it started to crash.

The crash is basically this: The whole system shuts down, the fan's stops working, the screen goes black, keyboard goes unresponsive, my power button and network adapter lights is still on, doe they are constantly on, they aren't blinking like usually, and my power button goes unresponsive so I can't push it to turn the system off/on, I have to pull the cable, and when putting it back it instantly starts, what should happend is that I put my cable back and I need to press the power button to start it.

At that time I also installed windows 8 because I wanted to try it, the longer I was using my computer the more frequent the crashes was, I tried to have a adapter to measure the electricity, and I come to the conclusion that it wasn't my PSU that couldn't handle it, the electricity was under the amount that my PSU can handle, if I remember correctly the PSU can handle 450W and I was around 350-400W when using software's and stuff. I also tried to run it with open case and a external fan directly on it, none of it helped.

So I tried to use linux (Ubuntu 14.02) and it worked fine, no problems, so I used it for a while, then I decided to try windows again, so I used 1 of my recovery disks, reinstalling windows worked just fine, but then after installing stuff it crashed again.

Before it used to crash after a few hours or like 1-2 days, or when I was watching videos online, but now it usually crashes when I am doing multiple thing, like installing several software's at once.

I tried to remove my GPU but it still crashed, as I am writing this, my desktop is running memtest to see if there is any problems, so I will get you the results of that.

I did have a bsod, but I think they were caused of the crashes.

My specs are:
CPU: AMD FX-8320 (8 core)
RAM: 16gb (4x 4gb sticks)
HDD: 2x 3tb hard drives and 1 1tb hard drive, all three is 7200rpm
GPU: Nvidia Geforce GTX 550ti
PSU: FSP450-60EP (450W)

Since I don't know too much about hardware I am asking about tips about how to diagnose what part of my computer is not working, softwares, what I can do like rewire, remove etc.
and if you have any ideas what is causing it, please tell me, I don't want to end up buying a completly new computer just because something small might be broken.

EDIT: I am not sure where to post this so if this is wrong category, let me know!

Thanks for reading.

Well... reason I haven't checked the cpu and gpu temperatures is because 2 reasons:
1) I did have a open case while having a fan right infront of my computer, I guess it could still overheat but if it overheats, it overheats in like 20 minutes sometimes..

2) It usually crashes when I am not doing anything that effects the performance much, its usually installing stuff or doing multitasking.

Also I don't think its the GPU since I tried to remove it and it still crashed.

Even doe the power supply is bad quality, it should still handle 350-400W
 
You do not have to open the case to monitor anything. Install coretemp for cpu temperature monitoring, and gpu-z for gpu temps.

As for the power supply, that is a common and very unfortunate mistake. Most crappy power supplies cannot even output half of their rated power, and even if they, do, the voltage and its characteristics are usually way off the atx specification. Often resulting in problems like your (best case), or burning down the entire computer (worst case).

Reason I had open case was to try and cool it down, not to monitor the temperature, but i'll try to get a hold of a better psu and see if thats the case, and i'll install coretemp and gpu-z to see if its a temperature issue
