I've got a small update after all the work I've been doing with my computer. Here it goes:
I've tried to recreate the previous error where I could play a video game while everything has locked up. This has been completely unsuccessful so I'm marking that up for a fluke.
Since then I've just been going over my previous diagnostics to see if I skipped anything. As far as I know, I haven't missed anything. The memtests for my RAM still come back fine and the temperatures for my CPU and GPU all read fine as well. My hard drive reports 0 bad sectors and nothing seems to be in error.
So basically now I'm down to timing the lock ups as well as seeing what causes them to see if possibly the PSU or Video Card really is at fault.
So far here is what I CAN do:
I can sit at the desktop for however long I want. I can install whatever I want as long as it doesnt involve opening a browser. I can change any configuration I want and I can run any tests that I want in windows. This means Ventrillo, AVG, MalwareBytes and CC Cleaner are all completely fine to use. (As well as Wordpad.)
I CAN'T open MOST video games. I can play some DOS base games such as Blood, Rise of the Triad and Arx Fatalis. While playing these, I let them run a good 30 minutes before thinking nothing was the matter. I will be leaving one up and running tonight, all night to ensure that I'm correct in this. (If not, you'll definitely know tomorrow morning, heh. *Note - Immediately after closing the game I played for 30 minutes, I opened a browser and locked up.)
The games that I absolutely cannot run are League of Legends, Fallout New Vegas, and Half Life 2. I have a huge library of games, but these were the only ones that I tested. It seems that I can play for up to 10 minutes before my computer locks up.
I also CANNOT run any type of media. This goes for downloaded videos, songs, or youtube videos. This is where things become a little strange however. For some reason, there is no consistancy to the time of lock ups for videos. Sometimes I will lock up after ten minutes of watching a video, and sometimes I will lock up after watching multiple videos for a total of ten minutes. The time is completely sporatic.
The last time I watched a video, the length was 12 minutes long. I locked up after 7 minutes in. I continously clicked my mouse until it froze, leaving me with the annoying long drawn out beep from my PC. The sound however, played for the next two minutes. It was crystal clear, as if I were still watching the video. The video itself, was still frozen at 7 minutes.
I will be looking into this further for the rest of the night. Again, I no longer have the laptop so this is going to be a long night.
If anyone has had any experience with locking up while the audio continues to play, please let me know.
Thanks again for your time.
