No Display but Fan is Running

[nihawma123]

My pc doesnt display anything. But the fan is running. What do you think is the problem? All my cables are good. What can I do to fix my PC?

Typically, it's a sign that the computer isn't completing POST. Which would indicate a hardware fault. Could also be a faulty video card/chipset or monitor.

First of all, you are posting in a hardware forum and no one [other than you] has any idea what hardware you are running. Post ALL of your exact system specs; ie exact motherboard, exact pw supply, exact video card, etc, etc. Do not post "500W pw supply" Post the exact brand and model# Do that for ALL of your parts.
Since this system does not POST, you will need to open the case and look. Each part has either a label OR has a mfg and part# silkscreened on the board.
