Have a Dell Studio 540 w/ Windows Vista, power supply took a dump. We replaced it and the PC worked for a couple of hours, we ran CCleaner and installed Avast. Turned it off for the night, next day when powered on it began a series of two beeps and would not boot. Reseated the memory cards, stopped the beeping but still will not boot. The power indicator light does is steady and doesn't flash/blink and is its usual color. If I press the power button withen a few seconds of turning it on it goes right down. If I wait a few minutes after powering up I have to hold the power button for a while (as if it HAS booted up). It's almost like it has lost all video output but I'm not sure. Any ideas?

You replaced with a new PSU?

 

Can you...did you run the Dell Diagnostics?

Hey Louis, thanks for the reply. Yep. New PSU although it is 450W up from the 350w that originally came with it. Nothing comes up on the monitor at all (I tried a couple of different ones) but the disc drive drawer opens and lights on the keyboard and mouse work.

Hi,

 

What is the colour of Power Indicator light in your monitor. Most monitors have different colour indicators to differentiate whether it is receving any video signal from the CPU. If your monitor is not receiving any Signal from the CPU, try a different graphics card.
