|Hi Insert, |
A) have you tried the monitor on another pc?
B) It could be the psu.
To check this you need to meter its outputs.
Some are to supply the graphics only.
Check the psu make and model type to ascertain which wire/connector supplies what.
C) Does the mobo have a monitor connector?
Some don't, which I think is crazy!
If so, have you tried removing the graphics card and using the connector?
Good Luck - Keep us posted..
