I have a fairly high end system (built back in 2011). Everything works flawlessly on it, except I seem to be having a driver issue (or what I can think to be a driver issue, as the error codes I've received in the past, and looked up online, pertained to a driver issue). I don't have the error codes right now, but just noticed when I went to hop on my computer, it had restarted, and my internet was out.

I have a dual-band Cisco Wireless adapter plugged into my computer, and when it randomly restarts, I have to unplug the adapter, and plug it back in, in order for the internet to connect again. This leaves me to believe its an issue with the adapters driver, causing the restart?
But I tried uninstalling, and removing any sort of drivers associated with it, and re-installing, to no avail.
The Wireless Adapter does seem to get fairly warm, after I my computer has restarted, but couldn't imagine that being the cause of it restarting my computer...

This has been happening, since I received the adapter, from what I can recall.
Didn't used to have this issue prior to it.

Any help would be appreciated!
I'll update this thread once I get the error code again.


System:
Windows 7 Pro 64-Bit installed on a 120gb SSD
i7 2600k overclocked at 4.5ghz
XFX Radeon HD 5670 1GB 128-Bit DDR5
16gb of Gskill Memory
OCZ StealthXstream 600w PSU

Additional Info:
5TB of WD storage, Water-cooled, and CPU idles at 34-35c.

You might want to check the bios to see if wake on lan is on. That MIGHT cause such a problem. Otherwise the basic way to diagnose problems like this is to try and isolate the problem. You can disconnect everything but the bare necessities. Then add one component at a time until the problem starts again. Try exchanging other parts or try the parts you take out in different computers. I would start by disconnecting the DVD, take all but one stick of ram out, unplug all but the necessary usb stuff. Even take out the Graphics card if there is an onboard graphics you can use for diagnosis. You can also try the wireless lan usb in a different machine to test it. You get the idea. Keep testing and brainstorming, You will get it figured out...

As I understand your post, your computer is restarting randomly? I think it is unlikely that your wireless adapter is causing you computer to restart. The fact that you have to unplug it and replug it (I assume you are referring to a usb adapter) could well be due to the adapter restarting after the restart BEFORE the USB controller starts up. I would open the computer and check for dust. Dust causes overheating-- overheating causes restarting. Check especially dust on the GPU. Also do you have a program that tells you the temperatures inside the PC? Check the temps. I would be very surprised to find that it is a driver issue.

The only reason I mentioned the Wireless Adapter, was because all other devices connected via USB work completely fine after the restarts, and the random restarts started happening, when I upgraded to this new adapter (from what I remember).

I thoroughly cleaned out all the filters and dust from my computer (something I do regularly, but did even extra this time). Have already had two restarts, within the past 2 hours.
All temperature levels are normal:

CPU Idle: 33c
CPU Max: 40c

GPU Idle: 44c
GPU Max: 45c

Motherboard: 30c
Motherboard Max: 32c

Hard Drives averaging 34c

Any suggestions for checking within the Event Viewer? And if it'll shed some light on this?
