I'm having real issues with my machine and have run out of options
Basically my machine will simply turn off (no shutdown just off as if the power was pulled), this will happen if left on the desktop overnight but can be quickly replicated by launching a game such as Battle for Middle Earth.
This just started happening for no reason a couple of weeks ago, there were no hardware changes or software changes of note!
So far I've swapped out the CPU, CPU fan, motherboard, SATA drive (to IDE), motherboard (to a different model - Gigabyte GA-7N400 Pro to ASRock K7VT4A). memory, AGP card, PSU, keyboard and mouse!!
I've unplugged everything that wasn't needed so I think the only thing I haven't changed is the monitor!
I've tried the machine on a different wall socket (but on the same ring) and with a different power cable.
I did find that when I was using the SATA setup that it would power off much quicker (including if left in BIOS for 10 minutes) and could be made to power down by just copying files.
I've also updated and downgraded where possible mobo & gfx drivers and bios.
This is driving me nuts, I've contacted Gigabyte support and they have ignored the mail for a week now!
Please help if you can...
