Since Wednesday, my CPU has never gone below 60 degrees Celcius, which is usually considered to be really hot in most cases. Now, if under load, my CPU can go up to 90-100 degrees Celcius, and proceed to crash after that point. At first I thought it was a problem with the PSU, but my doubts have gone up considering my other computer components have a normal temperature.

Here's a picture showing my computer temp. While using a few basic programs (Chrome, MSN, Winamp): http://boonce.org/up/cpu1.png


Operating System: Windows 7 Home Premium 32-bit (6.1, Build 7600) (7600.win7_gdr.100618-1621)
Language: English (Regional Setting: English)
System Manufacturer: nknow
System Model: Unknow
BIOS: )Phoenix - Award WorkstationBIOS v6.00PG
Processor: AMD Phenom™ 9600 Quad-Core Processor (4 CPUs), ~2.3GHz
Memory: 4096MB RAM
Card name: ATI Radeon HD 5700 Series

Any other questions, I'm available most nearly all day, and I'll be sure to respond quickly as I want this issue resolved as fast as possible.

Thank you in advance.

You're killing your CPU, or you partially killed it already.
http://www.cpu-world.com/CPUs/K10/AMD-Phen...WCGDBOX%29.html
Max. temp. is listed at 70C.

Did you clean inside the case already?
Reapply thermal paste, install extra fan(s).

Is this a laptop or a desktop?

Over heating is usually associated with an accumulation of dust inside the computer. Specifically with the heat sink and fan assembly on the CPU.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I have not. I do have an extra thing of thermal paste lying around somewhere but I need to pick up some compressed air if I were to clean it.

What's the possibility of it being a PSU issue, in the case the cleaning doesn't work. (The reason I'm asking is because it was a fairly cheap 550w PSU I picked up a year ago in the best interest of my budget.)

Desktop, custom built.

Unless fans are not running at correct speed, I wouldn't worry about PSU for now.
When you open the case, you'll see what's going on.

I've opened the case and touched the heatsink and confirmed that the sensors are reading (for the most part) correctly. It's pretty hot. I'll be sure to open it up tomorrow and clean out under there.

Thanks for your assistance, I'll be sure to follow up.

Beautiful guys, cleaning that dust cut the temp in half. http://boonce.org/up/4882_cpu2.png

A lot more dust than I thought, mostly because it was under the heatsinks fan and I couldn't see it until I got it under a direct light.

Thank you so much, a lot of help and saved me quite a bit of money since I was going to replace my PS (Even though I should anyways).
