PC specs are this:
MB: DFI lanparty x58 t3eh6
CPU: intel core i7 920
RAM: 3x2gb corsair ddr3 1600mhz ram
GPU: radeon hd4870
PSU: coolermaster 650 watt RS-650-PCAR-E3
The other day, while playing battlefield 3, my computer just switched off (had been running perfectly for 3+months i've owned it). no blue screen, just off. Long story short, did some digging and worked out the issue was probably the PSU (apparently this particular model PSU is rubbish).
Tested the PSU with a multimeter as per this site's guide, all voltages were within acceptable tolerances. Got to this step:Check Pin 8 (Gray, Power_OK) should be 3~5V to signal the CPU that power is okay to start. If not above 2.5V then signal not high enough to trigger CPU for start.
And sure enough, my multimeter read zero volts. So, i plugged the PSU into another machine i had lying around, and it booted/operated fine- which rules out the PSU as the issue.
When the PSU is plugged in and switched on, the "standby power" LED is lit, but the "DRAM power" LED is not. When the power button on the motherboard is pressed, connected fans will "twitch," but nothing is displayed on the onboard POST display.
What do you guys suggest?
Does all this point to a faulty motherboard?
