EDID from DVI port is OK, but monitor does not switch on

If you are comfortable with opening the case, you can try this: Unplug the power supply, make sure are constantly grounded (touching metal)remove add-in video card. Locate the "Clear CMOS" jumper (usually 3 pins in a row with two shorted via a plastic jumper). Remove the jumper and short the other 2 pins (if originally pins 1-2 with 3 open, short 2-3 with 1 open) for a few seconds. Then replace on original pins. Plug monitor into motherboard video port and power on. If it works, you can leave as is or try to re-install your video card following the same precautions when opening the case and probably changing BIOS settings to utilize the add-on card.

Not Good..
After you've checked that the video cable is connected properly, make sure that all the pins in the video cable plugs are straight and not broken off. Then test on another PC. Make sure your CMOS battery has not gone flat, as some PC's will fail to load basic drivers if CMOS memory is lost. The battery should show no less than 2.5v, if it's marked 3 volts when tested on a multimeter. If you can't test it, just buy a new one at the supermarket or hardware, usually around $4.00.
Next thing to try is your Video Card . If it is an on board one like most are now, there isn't anything you can do but try another card in an expansion slot or fit a new motherboard. At this point, I'm sad to say, you're better taking it to a PC shop where they will have a few things at their disposal to try.

The cases these days are hard to open, they use plastic finger hooks types, they go in easy but real hard to remove without damageing them.
Use thin flat blade to crack open at the bottom edge so the scratches will not be so noticeable, and work your way around, look out for cables attached to the front bezel also.

The blue screen is usually a RAM problem so i believe it has nothing to do with the dvi port problem (which might be burned, or just your graphic card needs the latest drivers). To make sure your RAM is ok run a memory diagnostics tool like memtest. Or if you have some spare RAM change it and see if it makes a difference!
