My laptop is a Sony VAIO VPCEE32FX. Its BIOS version is R0190Z5. Its OS version is Windows 7 Home Premium Service Pack 1. Its CPU is an AMD Athlon II P340 Dual-Core. Its CPU Clock Frequency is 2.20 GHz. System memory is 4 GBytes. I've had this computer since 2010, and been gaming with it since the beginning.
A couple of days ago, my computer randomly rebooted while playing Morrowind. Suspecting a virus might be the culprit (too much sailing the Internet High Seas), I installed MalwareBytes and HitmanPro and got rid of the viruses I found. However, my computer keeps randomly rebooting when gaming (predominately World of Warcraft) and it seems to be getting more frequent. In the beginning, it rebooted after a couple of hours. Over the past few days, that's been whittled down to 90 minutes, then 60 minutes, and now 30 minutes.
Could a virus be lurking on my computer still, or is it an overheating issue? Current temperatures on my computer (as told by SpeedFan) HD0: 40C Temp1: 46C Core: 53C (!?) It shows 3 fans, but they're all supposedly going at 0 RPM and I'm not sure what's going on with that.
I want to fix this, but I feel like I'd mess something up if I tried without guidance. I posted this same topic on Reddit looking for help, but I haven't gotten any responses. Please help me!!
