my computer is crashing whilst gaming, it happens about 15 mins into my gaming the monitor goes off and its light flashes indicating that there is no signal in some cases there is still sound. this is the same asw a problem i had about a year ago whilst in hungary, you see my bro sent me the computer as a present and on my first gaming experiance it crashed just like this, i was worried that it had been damaged but on taking it to this guy at the computer shop he could find no problem only to say that maybe there was not the right electrical currant in the house ( this being rural hungary with ancient electrics) and since everything was plugged in to an adapter i plugged the computer into its own socket and that was the end of the problem. i havent really done much gaming recently so having tryed and found this problem happening now whilst back in england. im so frustrated. i have had one or two problems recently where my computer completely crashed and would not turn on for about three or four trys but its been workin since. i know i have tons of video an audio files and programs but the computer has a big harddrive and pretty descent specs please offer some advice, i was thinkin that i might have a virus even thou im running mc affe and it says theres no virus my computer is running a bit slow and loading times also. please offer my cheap and free alternatives
