Question about Dell OptiPlex GX520 PC Desktop
I have adell gx520,when i connect the power cable,the power light blinks amber...and when i disconect the processor power cable(aux..12v)...the power button lights amber but does not blink...and the fans are all rotating....what can be the problem?
An Amber blinking power button indicates a low or missing voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Hello everyone, check your cpu - I've just had one of these in for repair and the cpu was faulty - removing the ATX 4way 12v lead let the pc start rather then detecting a short and shutting the psu down. Changing the cpu cured the fault.
