When it crashes, does the computer lose all power completely or are you talking about a Windows-related crash with errors?

Your +12v rail is way to low, get a new PSU

Dabith01 · Apr 14, 2015

Well all that happens is this: every time the PC crashes it reboots it self for no apparent reason, then when it turns back on it shows a black screen with white writing saying words to this effect: 'Your PC shut encountered an unexpected error and shut down to protect vital data, please choose a mode to reboot in: Safe mode, safe mode with only essential drivers, safe mode with command prompt, start windows normally' and i choose start windows normally every time.
hope this helps

Thanks for reading

New power supply seems best road to me also, especially considering you don't even know what it is.

Dabith01 · Apr 14, 2015

btw what exactly is a PSU faalin?

faalin · Apr 14, 2015

Your 12volt rail should be within 2-3% of 12 volts. You should be between 11.64-12.36volts, your +12V rail is at 10.1v

PSU = Power supply unit

Well thanks you two for helping me with this problem, also never mind about my last question: what is a PSU.

Thanks again

This looks like mis-matched RAM running at the wrong speed. You should be able to better identify what hardware you are running.

The +12v reading is too low (10.152 V). This could be caused by a bad power supply or the method you are using to get that reading.

You've both been a big help, Thanks again for helping and have a good day you both
