I have had no problems at all with my system , changed and/or altered nothing but this morning my screen has made a buzzing sound for 1-2 seconds then gone black straight after for a second and then everything is normal again. whats going on.
Win XP SP2 ,15.1" Triangle TFT monitor , 2.07 gigahertz AMD Athlon XP processor , MSI MS-6777 main circuit board .
Problem solved , some idiot was cleaning behind his work station yesterday and after pushing it back into corner dislodged the cable coming from the screen power pack into the mains supply so it was barely in the socket. I simply pushed it back in securely and voila .Just highlighting that it is always best to check the obvious first.
Thanks for the replies guys , and an interesting link from you Graham ® , makes good reading as there is a lot of stuff there that I didn't know so some good has come of this .
