"Tip: If you are asking for help to troubleshoot a computer-related problem, please be sure to include all the necessary information (ie: operating system, model number, hardware, software, etc) that will help others identify your problem for a speedy resolution."
Let's start with some easy things to do.
1. Pull the case cover to sniff out if it's heat related. If it is, the restarts just stop or are rare.
2. Any pests? Look up Spybot, Adaware, Cwshredder and Housecall on google.com These free tools are easy to use and can stave off a bug issue.
3. Use another browser. Microsoft still has work to do with Internet Explorer. Try Firefox.
Does anyone know why my pc just restarts itself (several times a day) when I just open up some new app or am just working on it as normal??
