Hello!

My precious gaming computer has started to behave weird by shutting down without a warning. There is no blue screen or warning message, its just like it has been unplugged! Its starts it self up and works just like nothing happen. It happens mostly when I play games and often when I am just browsing the web. :pfff:

The problem started after I had moved it between places from home to LAN party.

What I have done:

* Memory Test

* Hard Drive test (Windows disk check says all drives are OK, but Intel Rapid storage says I have one faulty hard drive that is brand new so I am not sure about that.)

* Check the power cable and the plug!

I think it is the PSU but I am not sure and I don't have 800W spare so I cant test it out. What are your thought? Should I replace the PSU with new one?

PSU would be my first guess, only way to know for sure is to switch it out though. You don't need 800W to run that system, a decent 600W should do fine, just stick with the reliable brands like Seasonic, Corsair, Enermax, etc.

You could also try a UPS/Battery Backup

But the PSU could very well be the issue as well now that I see it's a "Gigabyte" PSU. Gigabyte isn't known for their PSU prowess unlike the brands mentioned by bdiddytampa
