Random Shutdown No error messages

Hello everyone. I'm having a serious issue with my computer. I recently installed a new PSU, and ever since my computer shuts down without warning after about 10-15 minutes. I don't get an error or anything, just poof and off.

I've checked all the fans, and all are running just fine. I also checked to make sure everything is plugged in snugly. Also I was told to order an adapter to get the PSU to work on my system if that helps. Beyond that I'm clueless as to what to do here. Any and all help would be greatly appreciated. I really can't afford to take this to a shop anytime soon.

Below are my system specs. (The links take you to the Desktop/PSU/Graphics card/Adapter I own just to give you a better handle)

AMD Athlon 64 X2 Dual Core Processor 3800+ 2.00GHz
4.00 GB RAM
32-bit Operating System
Windows Vista Ultimate Service Pack 2
NVidia GeForce 9800GT
Corsair 750-Watt PSU

Sounds Like You Know The Culprit...

1. Get the correct adapter for your power supply. You don't mention whether the appropriate number of pins connected correctly when you plugged in the PSU, but you may need the correct 24 pin PSU adapter.. Or it's possible the power supply isn't the correct one for your machine.

2. Get a different power supply that works as designed.

Hope this helps.

maybe a little help

It could be that the 12V 4/8 pin connector is the problem. Your board only needs half of that connector. Some of the edges are rounded so the correct half should only fit one way. Overheating can also cause shutdowns. You can get HWMonitor, a free program from to check your temps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
