My PC restarts under certain tasks, first thing is battlefield 3, originally I thought it was an issue with just BF3 because it is the only game that causes my pc to restart, however today I was playing minecraft as well as using handbrake and it restarted.

It doesnt blue screen or shut down properly, it simply cuts out and restarts, I have a couple of ideas, firstly it could be dodgy RAM which is why im running Memtest86+ right now however I think it may be the power supply not suppling enough power because I bought my gaming pc from a company and it only started to restart once I added an SSD in.

Here are my specs:
AMD FX-8150 Eight-Core Processor 3.6GHz
AMD RADEON HD 7850 2GB
16GB DDR3 RAM
250GB Samsung SSD
2TB HDD
Disk Drive (Writes)
600W PSU

Do you think the issue is the power? If so what power supply should I need to power my pc with them specs? (I will post the power my supply produces tonight, however it would be very helpful if you could work out how much power I would need)

Memtest86+ just completed first pass with no errors so I don't think it is RAM.

Danform, it sounds like your computer (mainly CPU) is getting too hot. When the CPU reaches its thermal limit, it will cause the computer to restart to prevent it from frying. Which CPU heatsink are you using?

Strange it is only happening after you inserted the SSD - maybe try pull it out and run the test again?
If it is not restarting and as a SSD is not producing much heat at all, maybe the SSD is blocking the airflow within the case?

Please check:

- CPU heatsink - which model, and is the fan spinning properly?
- PSU make and model
- Case fans - do they spin? The exhaust fan near the CPU is important
- BIOS readings - what is temp in BIOS and do you see any alarms or things that doesn't seem right?

Also, what did you do when you installed the SSD? How did you go about OS install and such? Maybe you are just unlucky with a faulty model.

The SSD is in the corner of the case right next to my other hard drive so I do not think it is blocking air flow, I installed OS and some of my games on SSD and some games and everything else on 2TB hard drive. I can not pull SSD and run test again because it has OS, I say it only started after SSD however I did not play bf3 much then and i did not do any of these tests.

The case fan is spinning.

(I'm new to computers) Is the CPU heatsink the fan thats stuck on top of CPU?

I will check PSU make, model and wattage tonight.

How do i view BIOS Temps? Should I do it after playing a game or a cold boot?

I opened minecraft and use handbrakle to see if I could see what was wrong, it did crash again, here is what I observed. Using CPUID HWMonitor my cpu was apparently at 55 degrees Celsius when it restarted so I don't think its heat? However it did use double the watts as idle.
