Installed new ram and now my monitor shows no signal

Troubleshooting No Signal Issue After Installing New RAM in Your PC

Upgrading your computer’s RAM can significantly enhance performance, but sometimes the process can lead to unforeseen issues such as display problems. If you’ve recently installed new RAM and are now experiencing a “no signal” message on your monitor, you’re not alone. Here, we’ll examine common causes and step-by-step solutions to resolve this problem effectively.

Case Overview
The user installed a new 16GB (2 x 8GB) Silicon Power DDR4 3200 RAM kit into their system featuring a B450M-HDV motherboard. Initially, upon booting, the monitor displayed flickering colors, but subsequent attempts resulted in a complete “no signal” display. Multiple troubleshooting steps, including CMOS reset, reverting to the old RAM, and reseating the GPU, have not resolved the issue.

Possible Causes
1. Incompatible or Faulty RAM Modules
2. Improperly Seated RAM
3. BIOS/UEFI Compatibility or Settings
4. GPU Connectivity or Hardware Issues
5. Power Supply or Motherboard Issues

Step-by-Step Troubleshooting

1. Verify RAM Compatibility
2. Check your motherboard’s specifications to ensure the new RAM is supported, especially regarding memory speed and configurations.

3. Consult the motherboard’s manual or the manufacturer’s website for a compatible RAM list.

4. Reseat the RAM Modules

5. Power down your PC and unplug it from the power source.
6. Remove the new RAM sticks carefully and ensure there are no physical damages.
7. Reinstall the RAM, making sure each module is firmly and evenly seated in the correct DIMM slots.

8. Use the motherboard manual to confirm the optimal slots, typically slots 2 and 4 for dual-channel configuration.

9. Clear CMOS and Reset BIOS Settings

10. Since removing the battery did not help, try resetting the BIOS to default:
11. Use the motherboard’s jumper to clear CMOS if available.
12. Or, remove the CMOS battery again, wait a few minutes, then reinsert it.

13. Boot with only the old RAM installed to see if the system POSTs successfully.

14. Test RAM Modules Individually

15. Test each new RAM stick separately in the same slot to identify if one module is faulty.

16. If a particular module causes issues, replace it.

17. Verify GPU Functionality

18. Ensure the GPU is correctly seated in its PCIe slot.
19. Test with the integrated graphics if your CPU/motherboard support it.
