Memory: Kingston 8GB 1600MHz 9-9-9 DDR3 HyperX Red
(1 4GB Module and 2 2GB Modules due to TigerDirect error, Windows only sees 6GB, but that's for another day lol)
PSU: Thermaltake TRX-650M TR2 RX 650-Watt Modular Power Supply - 650W, 140mm Fan, ATX, Modular, 80 Plus
HDD: WD Blue WD10EZEX 1TB Desktop Hard Drive - 3.5", SATA, 7200RPM, 64MB Cache
(old 120GB drive also installed as extra storage)
What I was doing when this happened:
1) Cleaning files from my old hard drive after installing Windows 7 on the new drive.
2) Playing SimCity on appropriate settings. (The night previously, I played SimCity for many hours with no interruptions.)
BIOS does not show any heating or voltage problems. The CPU hits a max of 59 degrees celcius. All fans operating normally and system temperature is low.
Sounds like a power problem - PSU or otherwise. Surge protector does not have to be reset after a failure. Any thoughts appreciated.
I ran various burn-in tests and all temperatures remained below 50 degrees. BIOS reports all voltages as normal.
A few hours after testing, there was another power failure while doing nothing except for browsing the Internet. Checked mobo power connections. 24-pin connection was did have a partial disconnect, however if this is the problem, it confuses me how the computer was able to be turned back on after each failure without reconnecting it.
You say a power failure, does that include your mains power or just your PC restarting?
There is a setting in the BIOS to Restart after a Power Falure. Also, disable the feature to "Wake on Lan".
The motherboard IS designed for use with two video cards but you don''t have any, not sure if that would really affect anything but you might have to check the bios to see if there is anything you could disable, only allow onboard video out.
The PSU is adequate for use use with onboard video out.
You need to maintain 25% free space otherwse your virtual memory will be affected especially while moving files.
Double check all the connections, turn off at power before doing so, though.
By power failure, I mean that the system just abruptly and completely turns off. No reboot. The monitor and my phone charger, for that matter, do maintain power. The main switch on the psu mist be turned off a few minutes before I can turn the machine back on.
After the most recent failure, BIOS was corrupted, but recovered.
Did you find any resolution to this problem? I am seeing this exact same issue with mine using GIGABYTE GA-F2A85XM-D3H and 3.80 gigahertz AMD A10-5800K APU. It only does this when using no video card, only APU, and after installing the AMD chipset drivers (Catalyst). Then it won't even start Windows, just shows Win splash screen, beeps, and shuts down. I have to disconnect and reconnect power to get the power button to respond.
