As a non-gamer and with family members that frequently get cool looking games (and as a semi-retired techchick – yep doing web stuff more and tech stuff less) most of the problems I have noticed even with Windows systems (assuming that’s what you have) come when people install games.
No offense to any game programmers here but most of them are inferior and create havoc on your PC. I usually recommend that people forego the PC games and get stand-alone systems (Nintendo, Play Station etc…) for their gaming fun. Especially if you use your system for more involved stuff.
You next best bet is to hit the software manufacture’s website and see if they have any updates or fixes to known problems.
Also, it might help fellow gamers/techs to help you out if you gave specifics to your sytem, the OS and the game in question. Often a video card, sound card, processor, RAM, or the OS in general will be a culprit but without that information it’s nearly impossible to help you out.
Hmmmm, I think that last sentence was a part of a previous thread by the OP…Now be nice Doc Moss or I will unleash you to the crocs in my basement of hell.
