Recently, after leaving my pc off for a long period of time, hours or overnight, it starts with a blank screen. I can get the monitor to display video after turning the monitor off and on a several times. Otherwise it's fine.
ideas?


Graphics card is an ATI Radeon HD 5450. 2yrs old

it does start, it has a switch that is always in the on position. this switch turns blue when it has power and active. the switch turns yellow when it has power but screen blanker has reached the blanking time . when i turn on the power strip the cpu and monitor are connected to, giving both power, the switch turns blue then yellow. like it's idle.
i would try your suggestion but don't have the parts.

usualy the powerstrip is always on we strat the computer first with the case switch and the monitor second with is own switch that permit to the system to load the os did you try that this way to see if your monitor will blink yellow or start blue
