    Just bought this new rig. Everytime upon booting up a red ligtht flashes along with with blue bootup light. Any ideas how to get rid of or disable the red light from flashing.

    I would check the manual and find out what the red light means. If no info, contact the maker. We don't even know what make/model it is from the little pic. Of course you could cover it up with electrical tape but that doesn't solve the mystery.

    "Bootup" light? Do you mean "power" light?

    I suspect the red flashing light is the drive activity light. Lots of people like seeing it because it can give an indication if the computer is locked up, or just thinking.

    You likely cannot disable it with a simple setting. However, if it is the drive activity light, those normally are connected by two wires that go from the back of that light to the motherboard's front panel I/O header. This header is a cluster of pins and the front panel power switch, reset switch (if you have one), power LED and speaker (if you have one) will also connect there. Verify the wire does go to that LED light then simply pull one or both of those wires from the motherboard connector and tie that wire back out of the way. No harm is done if disconnected.

    Be sure to unplug the computer from the wall and touch bare metal of the case interior to discharge any static in your body BEFORE reaching in to pull the wires.

    Yes, Power light is blue and the red light beside it that's flashing is red. I was just wondering if something could be done in the BIOS to stop if from flashing. Apparently not. Thanks for your response.

    I've never seen that option in a BIOS menu - that does not mean none have it, but I doubt it. But if it is there, as noway suggests, it should be in your manual and likely is called "Drive activity light" or something similar.

    I looked through the BIOS and didn't see anything that would pertain to the problem. Next time I get inside the tower to dust it out I will look into disconnecting the the wire as you suggested. Not in the mood right now as I have been jockeying between two rigs Win. 7 and tweaking Win. 10

    If it bothers you and you want it just dimmed down a bit without completely concealing it with electrical tape you can use Light Dims:

    You can also get them on amazon.ca or amazon.com

    Understand "the problem" is between the ears, not with the computer! ;) Drive activity lights are there for a purpose and yours appears to be working correctly. :)

    But I understand some can be distracting - either by the flashing or just because they are just way too bright.

    Actually, virtually all cases used to have them. Only recently have some stopped including them - in part because they typically only work with the boot drive and many computers have 2 or more drives. But they also started to go away because it costs a few extra pennies to include them. And I do mean pennies! :rolleyes:

    That said, the ATX Form Factor still specifies that ATX compliant motherboards support them. So motherboards still have the necessary 2 pins in the header for them.

    I note on my Fractal Design case, there is only one front panel LED. But the case manual shows it can be used as either a power indicator or drive activity indicator - depending on where the two wires are attached.

    Most motherboards have a self-check sequence, and this is usually reflected through colored led state. Once it goes through the check cycle, the led typically turns white or green to indicate no errors. Some motherboards also give a single beep as a sign of all-good. This might be the that, just wired in this way. Some motherboards have this on the side, and if you have a transparent case panel, you can see the light when you reboot/cycle/power up.

    Ummm, no way would I say "most" motherboards. In fact, I would say "most" motherboards, by a long shot, don't have any LEDs - not until you starting getting up into the higher tier (more expensive) lines.

    I do believe all motherboards, however, indicate a successful "POST" (power on self test) and all will even indicate a successful post with a single, short beep IF there is a system speaker either integrated with the board, or a case speaker connected to the front panel I/O header.

    These system speakers used be included with all cases, then they started phasing them out to shave a few pennies off their costs. As you noted, some motherboards started integrating small button piezoelectric speakers, but sadly, most don't even do that. For those builds when no speaker is integrated with the board, we always add a System Speaker since they are so inexpensive and well worth it as they can be so informative - not just for the reassuring single beep for a successful post, but BIOS beep codes can be used for troubleshooting too. Note that $10.22 price is for 40 speakers! :)

    For a list of BIOS beep codes, check your motherboard manual or the following sites.
