New Pc Judders when 10 minutes into a game - Help needed :(

Hi!
So my newish computer has the following specs:

900w PCU AMD Phenom II x 4 965
Nvidia GTX 570 Asus
Asus M5A78L/USB3 motherboard
8GB RAM
Arctic CPU Fan
1080p 23' AOC monitor

Now any game I play I can start running at max settings on 1080p with no framerate drop or jumping(Skyrim/Hitman:Absolution/Deus Ex) The problem is that around 10 minutes into playing ANY game (Even rome total war) the game jumps ever 2 seconds or so, completely random when it happens :S

If I leave the game on the pause menu for a few minutes the jumping won't happen again until about 5 minutes into playing.

Now from what I have thought I believe it to be a problem with cooling or overheating.. because if it was a GPU hardware problem, there would be lag and jumping from the second the game starts.. not after a random amount of playing time.

What do you guy's think ?

How could I test to see if it is overheating on the CPU or GPU ? My cpu fan is quite a piece of shit really, wondering if a stock AMD fan would be any better...

Thanks in advance!

I don't get what exactly do you mean by jumping but... if you have already upgraded your audio and video drivers from the manufacturer, the next best thing would be to run CPU-Z from here... CPUID - System & hardware benchmark, monitoring, reporting

It will show you certain things and it may be easier to check stuff... you can also download Core Temp

It's hard to describe.. like graphics lag but it's not the graphics card otherwise it would do it all the time..

Downloaded Core temp and found that my CPU temp's ranged from 73 to 83 degrees C idle or with a light load (Hitman got 20% CPU capacity and was at 83 degrees C) I've looked at the cpu fan and it does go around, however I did not install the fan myself and I have a feeling something is going to be wrong with the thermal paste or cpu contact

I have seen where they differ from 60 to 70c MAX so getting to 83C I would call that Extreme and possibly why you are having that issue.

It wouldn't hurt if you buy some thermal paste, re seat your fan if you know it works and check the core temps again. Also make sure there is enough flow inside your case or you don't have it in front of the heater or fireplace!

Thing is I don't really have the money to pay someone to check it.. so if I take out the cpu fan and re-do it all and it still doesn't work I'd be pretty screwed

Well, I understand what you are saying, perhaps a good friend can help you do this? This is not even hard to but I get that you might be scare to do... I know I was the first time I did my first build.

You do realize that the more this issue happens the more risk you are putting your computer under, right? Perhaps is time to prioritize your life... what you want to spend the money on and what you need to spend it on

Well.. IM A GENIUS!!!! I considered what you said, went and got some thermal paste.. did about 20 hours of research, and swapped my 50 pound CPU cooler with a stock AMD one.. re-seated and paste re-applied. Temps went from 75 degrees C IDLE down to 34 degrees C idling.. just about to test at full load..

WOW I feel so happy!

Good for you... let us know what happended!

I Left it for a few hours at a very high load, and it didn't go over 52 degrees! no more framerate drop's, no more crashes!

Do not trust a PC repair shop to fir a cooler properly is the moral of the story!!
