Replaced graphic board and motherboard and when it is turned on there is no chime and no screen. The 4 diagnostic led lights light up. The graphic card was replaced due to when you started the computer all it did was chime every 4 or 5 seconds and nothing showed up on the monitor. The motherboard was replaced cause I broke off a diode when removing the graphic card. :( Any help would be appreciated.
Lets try the simple fixes first! A common issue I’ve seen on these older systems is the PRAM battery has died messing the system up from booting. Locate the battery in the bottom right corner.
Let’s see if that gets you going after you do a PRAM reset. What I fear is the Inverter has died or the CCFL’s.
