PC Randomly shutting down.

[Danko]

Hey.
Today my pc has randomly shutted itself down 4times. First 2 happened when I was on YouTube, and the last 2 when playing, MineCraft and Dungeon Defenders!
Anyway, had this for ages and no problems. Today the crashing started, it says nothing. It just shuts itself down. I tried looking at Windows Logs but found nothing.

Specs:

OS: Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack
CPU: AMD Athlon(tm) II X3 425 Processor
Motherboard: PEGATRON CORPORATION - VIOLET6
RAM: 6GB.

It MIGHT be because of overheating. Its 10+ hours a day on and its summer and freaking hot, I don't know

Hello Danko.

Check your CPU and GPU temperatures to confirm normal/abnormal temperatures using Coretemp and GPUz respectively:-

Core Temp

GPU-Z Video card GPU Information Utility

Post screenshots of both applications so that we can help you out:-

Could also be a failing power supply. When a PSU is failing it will just shutdown without warning, or errors.

Your GPU temps are a bit high for idling.. the should be around the high 40s when idling at most. When you're playing a game that 60 C could easy be nearing 80-90 C...

Your CPU temps look normal to me...

Also, what Wishmeister said could be right, what is your PSU's model and wattage? Could you fill that up in your system specs please? Thanks in advance..

It's a prebuilt pc. I found this from the manufacturers website.
HP Pavilion p6200 Desktop PC series -  HP Pavilion p6245sc Desktop PC Product Specifications - c01916927 - HP Business Support Center

Should be all info.

Danko,

Let's run an experiment.

Remove power.
Remove cover.
Blow out all dust using a can of compressed air.
Leave the cover off.
Make sure that the computer has at least 6 inches of clearance on all sides.
Direct a floor fan or a desktop fan or a table fan directly at the computer.
Turn power back on.

Problems decrease?

I'm not one on values unless they are really really high. I fly by the seat of the pants.

If you are interested in typical values, then I refer to this link:
ALCPU Forums • View topic - Core Temp - FAQ

For a very convenient tool for keeping an eye on CPU temps:
Core Temp

Incidentally, high temps, just like Electronic Static Discharges, will shorten the life-time of electronic components.

I have been looking on line to try and find out what kind of fan setup comes with that case and no joy. That makes karls idea even better. It would let us know quality of case air circulation/cooling.

 

[Danko]

I tried what karlsnooks said, tho I have no fan of any kind. So, I just blew the dust away and kept the case open, temperatures dropped maybe 5-10 (There wasn't really any dust) After a while, it crashed. BUT. I opened it today. Yesterday the case was closed and the dust was in, so I don't think its the cooling since I had this for like 2years or so and never had this kind of problems. I'm not saying that it can't be overheating but I don't think so, might it be some software failing / virus? Ill do a virus scan now.

Edit:
I'm not so sure...?

You opened your case and temps went down 5 ot 10 C. That means you have a cooling problem. Whether that is the only problem is yet to be found. Your GPU temps are high. Now show us your CPU temps.
Let us know what your scans find/fix. Beg, borrow, kidnap or buy a floor fan or the like.

 

[Danko]

The temperature dropped more like 20 or 30, last time when GPU load was 100% its heat was around 90+
Now its stable at 70-75. (I don't have the case open when those 70-75) Anyway, scanned with F-Secure and Malware Bytes and it didn't find anything.

I talked to my friend who has the exact same case, tho he might have some different parts. I told him to check his GPU Temp and he got the same, around 60-80.
