My HP Media Centre 7635 has developed a habit of restarting itself, all of its own accord. It happens at random times but mainly occurs when the machine has been running for a long period of time. I have attached two minidumps that the PC created when it happens and hopefully somebody on here will be able to shed some light on what the problem is as i am a relative n00b to this, and have no idea how to interperet minidumps. Any help would be appreciated. Thanks in advance.
