I am using windows 7 compatibility Dell inspiron one desktop computer, which is giving good performance regarding almost all its functionalities. Other specifications are like Gagabyte GA-MA78GM-US2H motherboard, ATI Radeon HD 3200 graphical interface, 4G RAM, 456 Hard drive, and also compatible with wireless connectivity. Sometimes I used to connect the machine with my newly purchased Sony Bravia HDTV, for playing and also for watching movies and video song clips in a big screen. The external monitor was also working fine till the last week, but suddenly from last week, whenever I connect the external monitor with the machine, to watch movies. When I turn on the monitor it simply flashes the power light but does not showing anything in the monitor. I am not having any idea regarding this problem. So what should I need to do? Any input will be appreciated greatly.
