Computer
The computer fails the POST:
The computer POST (Power On Self Test) ensures that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST, the computer will continue to start normally. However, if the computer fails the POST, the computer will emit a series of beeps during start- up if the monitor cannot display errors or problems. The following repetitive beep codes help you troubleshoot problems with your computer. For assistance, contact Alienware (for details, see “CONTACTING ALIENWARE“ on page 70).
NOTE: To replace parts, see the Service Manual at support.dell.com/manuals.
Beep code | Possible problem |
One | Possible motherboard failure - BIOS ROM checksum failure |
Two | No RAM detected |
| NOTE: If you installed or replaced the memory module, ensure |
| that the memory module is seated properly. |
Three | Possible motherboard failure - chipset error |
Four | RAM read/write failure |
Five | Real Time Clock failure |
Six | Video card failure |
