PC Crashing

[BraveNinjapoop]

Recently, when i start up a game, my computer Crashes completely, no freezes or halts, completely black and computer shuts off. Any suggestions?

My Specs:

I also just ordered an SSD, will be here Friday or so.

most likely the mobo protecting itself

125w cpu in cheap amd mobo = problems

a good read on mobo vrms and amd 125+w cpus and boards

3+1 phase vrm config should have a 95w limit
to help, you can undervolt and underclock the cpu

also be sure to update bios and chipset drivers

Did that, updated the BIOS, cant with the chipset. Checked out my Event Viewer with logs, to see what was happening becasue it still kept crashing, and i get this in the logs.... "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

i think there is a new BIOS update, the one you have is 1302 - 11/14/2012


Model
Asus M5A78L-M LX PLUS

you need to test you power supply, i had a bad power supply that did that, i have extea power supply

you mite have a bad pc case switch to or a wire in your system

It is most likely the power phase. As stated in quotation undervolt and underclock your cpu and see if that helps. If you notice it isn't crashing after undervolting and underclocking I would strongly recomend upgrading to a board with a more favourable power phase. the 3+1 power phase is not suitable for the FX lineup of cpu's and the mobo cannot cool itself properlt which leads to it shutting itself down.

first try lowering the core voltage to 1.2v
if its still crashing try underclocking to 3ghz (15x200)

pick up a vrm heatsink kit

what cpu cooler do you have?
if its not stock, put the stock cooler back on it
stock cooler keeps airflow over the vrms on the board

What psu do you have ? If your pc is shutting off during a game then its most likely the psu.

Not necessarily. If his motherboard is overheating, as FX CPU's often cause 4+1 power phase motherboards to overheat, his motherboard will have safety features that lead to a shutdown. Not saying it isnt the psu but wiith that motherboard its likely overheating the motherboard. Stress tests can be done to figure it out.

[Darkgodam]

It could be overheating. HWMonitor should show this. We could use some more info. Did it just start doing this and have you made any changes to your system ie. adding a new video card, what psu and how many watts.

Like other people had said, i belive its the motherboard, since my PSU is Cosair x600, i should be fine. Its running like a charm currently, but my girlfriend likes to turn off the computer by hitting the switch for the immdiete turn off on the back off the computer. I dont belive this is good for it, and ive never over cloaked anything on my rig before, nor do i want to the risk of what it could do. I have a Zotac GTX 750 Ti, and it uses Firestorm or something like that if i want to overclock/underclock. Ill try underclocking the CPU, but by how much?

[Darkgodam]

Yeah no thats not good for it. The pc shuts down while playing a games exactly the same as if she was to come up and hit the buttom on the back of the psu ? i only say the psu because i just went through this exact same headache with a differnt machine. The psu was brand new and I swore it was overheating.

Your RAM is at 11-11-11-28 that's slack timings for 1600MHz so chances are it's not configured properly.

hwmonitor will monitor the cpu and nb temps not the vrm mosfets

even generic ram can run 1600 cl11 1.5v, will not cause any problems
