My Computer doesn't shut down
I need some help.
I just built a brand new PC. Specs are as follows:
i7 2600k chip
MSI H77MA-G43 MOBO
Patriot 4x2 8GB RAM
MSI Gforce 650 ti
Samsung 8600 128GB SSD
Windows 7 Home Professional 64 bit
Computer works great, the only issue is that when I shut it down, it doesn't... The screen turns off, but the PC stays on. It appears that Windows does shut down properly, because when I power it up I don't get any errors.
When I do a reboot, the PC actually shuts down and turns back on, however, it doesn't shut down or even go into sleep mode properly.
I've tried the following already:
Updated the BIOS
video driver updated
Still can't figure out the issue.
I'm using a fairly old case (Cooler Master Cavalier), can this be the problem? The power button and reset button work fine.
