Sporadic OS Freezes and Unexpected Reboots
Posted on 2013-06-05
First, I am a hardware novice (I'm much better when it comes to software).
I may have 1 problem, or, 2 separate problems. I will try and explain the symptoms as best I can.
I thought at first these symptoms might occur do to a corrupted operating system (I'm running Windows 2008 R2 Standard SP1). Last Saturday I performed a clean install of the OS. The symptoms continued after the clean install, so, I doubt the operating system is at fault.
1. This symptom began far and few between and has progressively become worse as of approximately 10 days ago. My mouse and keyboard freeze unexpectedly. By freeze I mean neither the keyboard nor the mouse seem to have any effect on the computer. CTL-ALT-Delete does not have any effect. I press the hardware reset button in order to reboot. About as often as my computer keyboard and mouse freeze, however, the computer will unexpectedly reboot as if the hardware reset button were pressed. This sudden reboot does not seem to be tied to a specific application.
2. This symptom involves Internet connectivity. The symptom started more progressively than the first symptom. As of today, about 50% of the time I wish to go to a web site, or, download a file, the connection between my computer and the Internet fails. My solution is to unplug my router and plug it in again. After the router talks to the cable modem all is well until the next time.
My hardware layman brain is thinking this may be a power supply issue. The computer was built in 2006 and is almost never turned off. I have ordered a power supply tester from NewEgg Software which should arrive tomorrow (Thursday, June 6th).
Any assistance you can offer is greatly appreciated ... David
