I am using Windows 7 Ultimate x64 Retail. My computer randomly locks up while playing video games. It will either lead to a lock up or after 30s-2minutes it will start responding and speed through all the commands I sent. So like 25 task managers suddenly appear at once.
This doesn't happen consistently at all. Could lock up 5 times in one day or not at all for a week. Seems to be a different BSOD each time, but I am not sure.
Most of my system was custom built around a year ago, recently replaced my graphics card 3 or 4 months ago.
There are quite a few things broken with this OS install, but I am trying to hold out for Windows 8 so I don't have to reinstall everything twice.
