PC Crashing on high stress

[Khyodyr]

Hello, before I will discuss the problem I will post the specs, eventhough I don't know the exact brands because I did not built the system myself.

ASRock B75 Pro-3
Intel i5-3570
Nvidia GTX 660 OC
8 GB RAM (One stick)
1TB Harddrive @ 7200 rpm
750W Power Supply

Whenever I start playing a game that requires quite some stress on the hardware it starts crashing, it gives me a blue screen and it will not restart by itself. This crash can happen within 5 minutes of me playing but sometimes I can play for 1 hour without running into any trouble. I have been monitoring the temperature of the hardware and both the processor and graphics card will not go above 70°C.

When I restart my computer (manually) I got the following errors when i check the logs:

1) A problem has occurred with one or more user-mode drivers and the hosting process has been terminated. This may temporarily interrupt your ability to access the devices.

2) The device MTP USB Device (location (unknown)) is offline due to a user-mode driver crash. Windows will attempt to restart the device 5 more times. Please contact the device manufacturer for more information about this problem.

Both errors occur at exactly the same time.

If someone could help me out with this I would really appreciate it since I've done everything to my knowledge (which is not very much) to see what is causing it.

Thanks.

What brand/model is your PSU?

Have you run memtest86 for 5 passes to check the RAM? Do this for sure.

To react to all of the above:

1) The powersupply is an MS-N750-VAL and I didn't have any luck with memtest yet (Can't get the pc to boot from CD).

2) I just have a keyboard and mouse plugged into the computer.

3) I will try the software you linked

Thanks so far.

Edit: I am glad someone asked for my powersupply, I opened the case to figure out the brand and model, and I see it has really bad reviews.

This could be the problem for sure. Replace it with a quality unit. (Antec, XFX, Seasonic, EVGA (B2,G2)) 550w is plenty.

I am currently looking at the XFX TS 550w, I hope you think this is good enough? I will get back to this when I have it all installed, thank you.

I just installed the new PSU this morning and everything works fine again, thanks all.
