The problem is now worse because 9/10 the monitor wont receive a signal from the PC and goes into standby. I have to turn the PSU off at the back of the machine and switch it back on in order for the screen to receive a signal and switch on as normal. Sometimes it wont turn on at all.
The psu is about 10 years old now so I know it needs replacing. I did get a message come up on the screen saying something was wrong with it but now I cant get it again to take a photo of it, this is just after power up.
How can I actually diagnose it? So I don't go out and buy a new one and it turns out its another component?
