jondkh,
Below is what the error code LED's 1,3,4 represent and what to do to resolve.
"A possible system board resource and/or hardware failure has occurred."
Resolution:
- Clear CMOS.
- Disconnect all internal and external peripherals, and restart the computer. If the computer boots, add the peripheral cards back one by one until you find the bad one.
- If the problem persists, the system board / system board component is probably bad.
Thank You,
Dell-Jesse1
