Can you pin the problem down to a particular game? I need to to go into the Event Viewer and look for the Error that corresponds to the time a game crashes. The Event Viewer holds logs of everything happening in the System and Apps. We can usually get enough information to pin down a cause and hopefully a resolution:
Control Panel> Administrative Tools> Event Viewer>>>Do the same thing on the System and the Apps:
Click on each to open the log> right click on the Error> Properties> click on the Copy button on top right, below the down arrow> Paste here (Ctrl V)
You want the Error(s) that happens at the same time as the crash. Ignore Warnings and Information events. If you have recurring Errors with the same ID#, the same Source and the same Description, I only need one copy.
