Hi guys.
First I am sorry if this does not belong in this category. I'll delete and post it in the correct one if that's the case.

I'm having a problem that I don't know what could be the reason for it.

specs:
cpu Intel i5 2500K 3.30GHz
board Asus P8Z68-V PRO GEN3
ram 4x2GB DDR3 PC3-12800 G-Skill
gpu Geforce GTX 970
drives SDD 250GB Crucial MX100+HDD 1TB Samsung HD103SJ
psu Corsair TX 750W v2
OS Win10 64bits
(besides the gpu and sdd of maybe 1 year old.. everything has 4 to 5 years)

Here's the situation:
Sometimes (pretty much every single day now..) mainly when I'm playing something a bit heavy (e.g Paragon) but also happens when I'm just browsing the web.. my monitor suddenly goes black. Sometimes after a few secs it turns back on with the message "Graphic kernel driver stopped responding and recovered etc" and I can go on with my life (but sometimes it still happens again..).
Other times.. the screen keeps black and the only thing I can do is to power off and on my desktop.
And other times.. is goes black and after a few secs my desktop reboots and displays the message that my CPU has overheated.
Only yesterday I also noticed that if a hit the case with my knee.. the screen goes black and displays the driver message (don't know if it was just a coincidence.. because there was a delay between my knee hitting the case and the screen going off).

At first I thought it was because if the graphic driver (have been reading forums with people complaining about nvidia latest drivers). So I used DDU tool to completely uninstall the drivers and eliminate all traces.. and did a clean install of the drivers that came with the graphic card's cd. And also tweaked some settings like using optimal power for performance and switching off vertical sync in the 3d options and even adding the tdrdelay in the registry. Problems continue.

Now I'm thinking it might be a CPU problem.. I monitored with CPUID during a match and saw that the temps were above 90º (194F). Well.. about that I intend to clean the inside of my case but only this weekend cause it's when I got the time for that unfortunately. And also need to pick up another can of air and thermal paste.

If the problems persist.. I will do a memtest.. to see if it might be related to some faulty ram.

And last hope how can I test the psu? to make sure it's not a power related issue.

I would like to know if anyone is or had any problem similar to this and probably guide me in the right direction.
I'm not a well informed user regarding computers so don't even know if what I wrote makes sense and if it's a good plan.

I would appreciate any thought on this!

Well.. after a new cooler and a clean windows install.. everything now works perfectly fine! xD
The old cooler was clogged with dust and was.. well.. old xD.
thank you for replying.

during that same test where I got more than 90º for the cpu.. i got 65-70ºC (149-158F). That's not high right?
As I said, I intend to clean the dust off and get a cooler for the cpu because I was hopping to oc it. But I started having these problems so I put that on hold. And also.. while I am browsing through the web.. it also happened. And the temps couldn't be that high. So this is all strange.

And ram problem is probably out of the question?

Also how can I test my psu to make sure it is still providing enough power or has no problems?
 
65-70C isn't bad, typically, if that is for your GPU. If you are getting 90c, with a load, I doubt you are running much cooler doing less intensive things. Ram usually gives a blue screen, when it is going bad, but I guess anything is possible. I believe HWmonitor will show PSU voltages. You might be providing enough power, normally, but it could be that the power is unstable. Just noticed the hitting with knee part, make sure everything is properly secured in its slot and connectors.
 
Voltage wise.. the values are between the min and max according to HWmonitor. And will definitely give everything a good old scrub. I'll then post if that fixed the problem.. for other people probably in the same situation.
Thank you!!
 
ohh.. sorry about that :chaudar:

about that I don't know what values to look at in HWMonitor.

and also.. just noticed another value for my GPU.. is 62-65º high for when I'm not playing?

Here are the pictures I got from openhardware monitor with some values. These were taken after 2hours where I've been using my pc just for browsing the web. Can you please check them out and give me your opinion about the values? Sorry for relying so much..
