Question about Dell Optiplex 755 Desktop Desktop Computer
The light on the LCD screen stays yellow?
I would start with puling out the ram chips and see if it works,
If you get some beeps and video works with ram chips out, then its a bad ram chip.
If thats not it.. unplug all cards cd/dvd rom and harddrive to test motherboard and CPU chip. see if you can get video to work with everthing but cpu and power suppy unpuged
