Hi, everybody.

I'm having one particular issue with my pc ever since I bought it, which was almost three years ago. My pc reboots itself when I'm watching a video (online and offline) or when I'm playing a game. Sometimes the screen just freezes together with high pitch sounds.

The pc just reboots without displaying a waring message of any kind, also when I unselect the option "restart computer" in the section for advanced startup and recovery settings.

I cleaned the computer, the fans work properly, no crazy temperatures (have tested it with HWMonitor and all temps are avg. 29 Celsius) and Windows shows a Kernel-41 error which doesn't help me either.

After having searched the internet thoroughly I unfortunately didn't manage to find a solution.

System specs:
* MSI P55M-GD45
* Intel core i7-860
* ATI Radeon HD5750 - 1GB GDDR5
* OCZ Gold K2 - D3 4GB 1333-999 LV
* CoolerMaster Real Power M520

* Win 7 64-bit
* As a monitor I'm using my Samsung LCD TV

Would appreciate to get some advice from you guys.
Thanks in advance!

This sounds like it might be a bad power supply.

I assume that since you've owned this computer you've re-formatted at least once and the issue carried over through the wipe?

If you can I would try diagnosing the issue like this.
1. Wipe the machine if you haven't before and install fresh drivers from the manufacturers websites not off of the disks that came with your parts this will give you the best chance of eliminating software based variables.
2. If you have another computer try swapping the video card and seeing if it still happens or if the crashes happen on the other machine if you don't already have a video card and you can't borrow one save this until last because this is the most expensive bit usually. (this first because its easier than swapping a PSU)
3.If you don't have another computer or an extra video card lying around test the ram using memtest86+ or yank all the sticks out but one test it then go through each to verify that the ram isn't the problem. (Bad ram usually results in a BSOD not a sudden reset but this is cheaper than ordering new parts and quicker than rewiring your machine even if you have a spare PSU.)
4. Try a new or borrowed PSU. at this point if you've eliminated software as an issue, your video card is known good, your ram has passed testing, your PSU has been replaced and you're still having issues you are both unlucky and you have a bad motherboard.

Good Luck!
