I have been having this issue with this computer about a year now, I didn't think anything of it because it didn't happen very often and so I just dealt with it, but now its starting to happen more often. My computer has been just randomly restarting (only has been happening while I am playing a game). At first it started just restarting randomly, blank screen no error messages, then it moved to giving me a blue screen a few months later saying that a thread was stuck in the device driver. A few months after that it went back to just restarting with no warning, and no error code ( All while I'm playing a game, its never done it while I am just browsing on chrome ). Anyways, I searched solutions on google for this issue, and came up with 2 solutions and one person saying it was my graphics card damaged. The two solutions were 1. Update my graphics driver, and 2. Update my bios. I did both of these, and I am still running into the problem. Any help would be appreciated. If it makes any difference my warranty is still in effect, but I'm really not sure on how to go about sending it to HP.
