Description
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007e (0xffffffffc0000005, 0xfffff880068c3e15, 0xfffff8800b62c4d8, 0xfffff8800b62bd30). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 052815-10358-01.

I had this problem where there is an unknown device in device manager, USB Composite Device. It is not always there but most of the time. It may go away after a reboot but not always. There is nothing plugged into my USB. It can sit turned on and not being used for two days and out of nowhere it will crash, usually when I am asleep. Ive tried reinstalling and updating the chipset drivers and all the rest. Hoping one of you may be able to shed some light. Otherwise it preforms great.

Thanks; Frustrated
