Hi, A few months ago, I started having mildly annoying issue with my PC. Any time I try to shut down my computer, either by going to start --> shut down, or just by trying to manually power down the computer by pressing and holding down the power button, my computer instead reboots. For these past few months I've had to power down the PC by flipping the switch in the back. I've reformatted my hard drive a couple times since then, and the problem still persists, so I've pretty much isolated it to it being a hardware issue. A friend of mine found somewhat of a solution to the problem. Apparently if I open up my PC and disconnect the DVD drive manually, I can shut down my PC normally without any problems, however this isn't really a viable solution for me since I use my DVD drive fairly often. Also, I know the problem can't be related to the DVD drive since I've tested this with two different DVD drives, and the problem persisted with both of them. My friend thinks it may be an issue with the hard drive. Any thoughts on what could be causing this?
