I am not that great with any technical Hardware know-how but I might be overworking my computer for gaming: -Pretty much if there isnt a beep a few seconds after start up it will only show a black screen. -Screen Turns black during gameplay. -Loud fan noises during gaming. I clean out the dust but I don't think it helps that much and playing my games on max isn't the smartest idea but I really like high quality visuals. Here is my Specs Windows Vista 64-bit Acer Aspire M5700 Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz 2.50 GHz RAM: 4 GB Video card: ATI Radeon HD 5700 Do I need to upgrade/replace any of the devices or buy a whole new computer because the loud fan noises are getting annoying when I play my games as well as the black screen crashes.
