Dual Monitor PC Shuts Off

My PC has been running smoothly for months without incident. Recently I set it up with a second monitor. I couldn't help but notice that my PC would shut off when I have too many tabs open. Now it turns off when I'm in the middle of playing my video games. I do stream video while performing these tasks... but that hasn't been an issue before. I would stream video and use PhotoShop5 with no incident waaaaaay before I installed the second monitor. No issues with staying on.

My PC is running Windows 7. It has three fans installed, and I cleaned them recently. The issue didn't go away after I cleaned the fans. I have no idea what to look for to fix the issue. How do I check for power supply issues? How do I determine it's overheating? And if I do find out what's causing the issues how should I go about fixing it?

Thanks for the help!

:welcome: HimaAngel

We could do with some further information about the hardware in your desktop so can you run Speccy and post the url for us http://www.piriform....file-to-the-web

Can you tell us the brand and model name or number of the PSU as that is something Speccy cannot tell us, if you do not know the PSU details you will need to take off the side of the case and make a note of the information that should be found like in the screenshot below.

Results from Speccy are found here: http://speccy.pirifo...wgMUAogBSh6gY0j

There's a warranty sticker on the side of my PSY, so I googled what it said aaaaaaand... I'm pretty sure this is what I have installed: http://www.newegg.co...N82E16817822008

Underneath the warning about voiding a warranty if it was removed, the sticker said, "DA series 500W diablotek 500 watt atx power supply" (Just in case my google search turned out wrong.)

Thank you for the help, by the way!

Thanks for the update HimaAngel :thumbsup:

Can I ask if the computer has ever been overclocked.

I suggest that you seriously consider not using the computer until the present PSU has been swapped out and a quality brand replacement that has the required power output has been fitted.

The above is based on the following, 1: The power output on the +5V and +12V rails are all over the place with the +12V output effectively frying your CPU (see screenshots below of your PSU output and what the correct outputs should be) 2: The safe thermal footprint of your CPU = Maximum operating temperature 55°C - 71°C but Speccy is showing the MB and CPU temps at 93 °C and this is while the computer is not under load - once you start gaming etc this will increase dramatically and the MBs thermal sensor will shut the system down to protect your hardware AMD Phenom II X4 925 - HDX925WFK4DGI / HDX925WFGIBOX 3: The appalling feedback from Newegg customers, example;

Cons: they tend to burst into flames, if you have a problem, forget about getting an RMA, company unresponsive.

http://www.newegg.co...N82E16817822008 4: There is no information on the brand on the PSU database http://www.realhardt...vos/Page541.htm

Brands of PSU to trust + brands of PSU to avoid http://www.10stripe....d/psu/brand.php note that again there is no mention of the Diablotek.

As an asides HimaAngel I note in your Speccy report that you do not have any anti virus protection, are you aware of this and the potential risk that you are at from malware attack.
