I built an amazing gaming rig, everything was running beautifully for roughly 2-3 weeks. It all started whilst playing Rome Total War 2 " a very demanding game", my pc literally just shut down without any warning, like it completely lost power. Seconds after Id press the power button and nothing would happen. It eventually turned back on after waiting several minutes, didnt have another unexpected shut down till a week later and each time it was happening more frequently to the point of not being able to have windows open for more then 5-10 minutes. Also Id like to note that I've heard like ticking/popping sounds which could be the mobo shorting out?

Now I've only really done a couple tests... at one point I thought it was a faulty GPU so i changed it with an older one I had laying around, same problem. To clear up any heating issues, Id sit in BIOS and watch the CPU and MOBO temp idle around 32 C.

Iam about to try swapping some ram sticks and see what happens, if that isnt the issue, it must be a faulty mobo which in that cause I know for a fact I can RMA it.


Does anyone know if an outdated BIOS version can cause unexpected shut downs? My BIOS version is 3305 and I have no idea how to update it

Here are my pc specs

i7 3930k six core processor
Corsair 800D case
Corsair dual channel 1833 16gb
Geforce GTX 780
Asus Sabertooth X79 Mobo
Asus Xonar Essence STX sound card
ThermalTake water 2.0 extreme CPU cooler
Windows 7 Home Premium
Seasonic X Series 1050w Gold
120gb kingston hyper x SSD
1TB WD hard drive

You skipped the most important part of your PC specs, when your "computer just shuts down as if it lost power" Im immediately curious about the power supply, and with a 780 and a 3930 you don't exactly have a low power build right now.

I would avoid updating your BIOS, it has nothing to do with these random shut downs and generally a BIOS update isn't a good idea unless you need to, if it aint broke don't fix it.

Opps lol My PSU is a Seasonic X series 1050w Gold. It has really good reviews but if anything, I hope if will be just the psu lol

Ive let the pc run for the past 45 min in the BIOS screen and its still running so I doubt its a power issue? After making it to windows, id either be just browsing the web or even just at the windows screen and it would shut down.

I've also put in my OP that Iam using a 120 gb SSD for my boot drive and OS. I just recently heard that SSD arent really the most reliable component
