First off, its an older system, specs can be found here, Compaq Presario 5310US Specs. Only real changes have been added PCI card with sata adapter for back up hard drive, additional 128mb stick of RAM (so 384mb including the original), and replaced the modem PCI card for a Nvidia FX5500. Don't have the money to upgrade at the moment, and need this computer for school, the random restarting is making that difficult...
As of right now, I have 0 malware/adware on the computer after following majorgeeks.com read and run guidelines which included running Spybot Search & Destroy, Malwarebytes Anti-Malware, and SUPERanti-spyware. I have also gone into safe mode and unchecked the "restart automatically" box in the My Computer>Properties>Advanced>Start up and Recovery. I have never gotten a BSOD except for during running combofix following the MG guide.
The restarting isn't operating system specific either since I have Ubuntu installed as well, and it still resets in that OS, again without warning. I have had this restarting problem for a good year now, and there is minimal dust in the case, having blown it out on multiple occasions with canned air, hence why I don't believe its a heat problem. the other thing that leads me to believe its not heat related is that it happens 100% of the time when I load Knights of the Old Republic and I'm first choosing my class on a new game, despite how long the computer has been on (meaning <30 sec after being off 6 hours). I have also run memtest86 and it comes back with 0 errors on the 2 sticks, ran each separate.
