Very strange problem with PC.

My PC is acting strange. I can't get it to boot.

It turns on by the back switch and the fans go full blast apart from the fans connected to the motherboard.

I cannot turn off the pc from the power button.

No signal.

Is my motherboard fried?

Does not sound good!

You could try a CMOS reset and also try with minimal components. Do you the full specs of the system.

How long ago did it start doing this?

I agree, it doesn't sound good at all.

Sunday. What happened was I moved my pc to the other side of the room. Plugged it in, switched it on, boots up, everything is normal.. then I turned it off and then it wouldn't turn back on ok.

I forgot to mention that I plugged in my modem power connector to my usb hub by mistake. My usb hub got so hot it felt like it was going to melt. I think this could be part of the problem.

Anyone know what it could be? I am thinking its probably the PSU.

Another thing, the pc turns on once its plugged into the wall and not from the power button.
