Recommended Action
1. Verify ROM, reflash if required
2. Remove suspected card, reboot
3. Clear CMOS memory, reboot
4. Replace system board
1. Clear CMOS memory.
2. Remove expansion boards.
3. Replace system board.
1. Run Setup (F10).
2. Check DIMMs for proper
seating, type, compatibility.
3. Remove DIMMs singularly and
reboot to isolate faulty DIMM.
4. Replace system board.
Rearrange the DIMMs so that
each channel has the same amount
of memory.
Check kybd connection or keys.
Check connector for bent or miss-
ing pins. Replace kybd. If 304,
possible system board problem.
1. Reseat graphics card.
2. Clear CMOS.
3. Check monitor connection.
4. Replace graphics card.
1. Determine if hard drive is giving
correct error message. Enter
Computer Setup and run the
Drive Protection System test
under Storage > DPS Self-test.
2. Apply hard drive firmware
