I have a Gateway DX4300-15e that has recently started randomly blanking out. Not sure how to describe it, the screen disconnects and all the external devices lose power, the hard drive will continue reading for a few seconds but the HDD light will not blink. The power button stays lit, but is unresponsive to either pressing or holding. With music playing, the sound dies connected to either front or rear jacks. The fans continue to run. I have to completely unplug the system to get it to shut off. System logs don't show anything that could be causing it.
I've tried system restoring it back to the earliest save i had, and then disabling auto updates but that didn't help. I tried running it in safe mode, also didn't help. I tried disconnecting all the external devices, still cuts off. I've checked the voltages on the PSU with a voltmeter and all are within spec. I pulled all the internal pci cards out of the case, disconnected the DVD drive, and moved the monitor from my graphics card ports to the motherboards and removed the card, still cuts off. I've ran memtest and it shows no memory failures.
I'm not sure what to do next, I'm afraid if i try to reinstall windows it may lock up midway and screw up everything. I don't know how to check anything else. Any advice would be appreciated.
