Amd Phenom II x4 955BE
on a GIGABYTE GA-MA790GPT-UD3H AM3 Mobo
With 8GB of DDR3 1600
Running Windows 7
Now here is my issue. I put my computer in sleep mode to save power and to use a Wake on Lan feature to only power it up when I needed to when I was away from home. I came to my computer this afternoon after it had been in sleep mode for 12-15 hours and pressed a button to wake it up, and it powered up but I had a blank screen and nothing was happening. So I tried to restart my computer and my restart switch would not reset the computer, nor would the power switch. So I turned the power supply off to get the computer to turn off. When I tried to power it back up the computer would turn on but would not post.
I have tried reseting the CMOS battery by jumper and by removing and replacing the battery back in. Note this computer had been running fine for over 1 year with no issues so this is not a new computer. When I turn the computer on by switch all the fans come on inside the computer including the CPU fan. Nothing happens at this point the screen stays black and the computer will not do anything. On a side note it makes my Raedon 5850 fan spin up and be very loud. I have since unplugged it and ran on the motherboards on board graphics to trouble shoot. At this point also my power switch and reset switch will not turn off nor restart the computer.
I do not have a spare CPU to test to see if it is the motherboard or the CPU that might be dead or malfunctioning. Does anyone have any ideas of what the issue could be or if it may be a dead mobo or CPU?
Any help would be greatly appreciated.
