I got a PC here which has suddenly failed to turn on the system monitor. According to the owner, he was working on it and then the monitor switched itself off and went onto standby.
I have tried the machine with another monitor and there is still no action. The graphics are integrated on the mainboard, therefore I installed a PCI graphics card in an attempt to bypass the onboard graphics. However, it is still not switching on the monitor...or any monitor for that matter.
