I have already had the irritable Hard drive failure on this machine, which was a pain to take apart and install a new one, then once I had installed the new hard drive, I tried the power which wouldn't come on

A red light appears by the power button but doesn't turn it on at all, more alarmingly i had to take the machine apart again and tried the power again, which led to a fast clicking/ creaking noise coming from the power supply

Philips told me it could be a fault plug, but I have since tried different plugs, all of them track back to the same issue, the creaking/ fast clicking noise, any help would be very helpful!
