have recently upgraded to W7 having considered the imminent non support of XP but still have the older XP in another room - it has much of my work and is still used - today when started, after about a 2 week rest, the screen remained blank with the message "no signal" displayed (briefly) - every thing appears to be connected and the "no show" is surprising - oddly the keyboard doesn't work either - can anyone throw some light on this please?
