Hopefully, you computer-literate fellas here might be able to help me out. Well, I'm having a constant problem in which my computer decides to shut off one of the two USB hubs located on the back of my tower after a nondescript amount of time. Now, this is a problem because it makes both my mouse and keyboard useless unless I plug them into the other hub. Then they function fine, until the second USB hub also shuts off, and I have no way of doing anything other than shutting off the computer and turning it on again. Rinse, dry, repeat. It's all a very unhealthy process. Here are some details: -Running 64-bit Windows 7 -USB hubs shut off without any warning or pattern -Disabling USB selective suspend has not had any effect -Going into Device Manger, disabling and re-enabling one of the hubs that has shut off will make it work again for a short period of time -Complete scans for malicious software with multiple anti-virus programs, including Norton and MalwareBytes, have come up negative So if you guys could lend me a helping hand, that would be very, very much appreciated.
