Red light on front panel

I am not sure if this is the right section but it should be related to the motherboard.

I recently put a new power supply in the computer. Everything is hooked up right because it booted up with no problems, no beeps, no sounds. Games run good, everything is smooth.

However, there is a red light on the front panel. It's not on all the time. But for example if I open 10 Firefox windows in a row right now it will start flickering red. Sometimes it just flickers red when I am doing nothing. Or if I am just doing some typing like this.

Before I replaced the PSU it was usually a green light which is noticeable. I haven't seen the green go on yet.

Is this a sign of something wrong?

Normally a red flickering light on the front panel indicates HDD activity.

I never saw the red light so much before replacing the power supply. I don't see the green light anymore.

Should I not be worried at all?

In the absence of any symptoms I would think you have nothing to worry about. Check the cabling that goes from the front panel to the motherboard and make sure that is all wired correctly. If you like you can disconnect the front panel HDD cable which goes from the front panel to the motherboard. If the red light goes away then you know for sure what it is but it sounds like a HDD indicator to me. As for the green light make sure the other front panel cables are in place and seated correctly. It may be a power indicator which has come off the board while you were installing the PSU.

I checked the cabling this morning. Everything looks normal. Still haven't seen the green light go on.

:hello:  It doesn't seem normal for the light to just change colors but I wouldn't worry. just double check your Led connections to your mobo and make sure none of the wires came off from your psu install.

My new Thermaltake Gameing case shows a red light for hdd activity and a Blue power on light.

Is your power button and reset button working okay?

I haven't tried the reset button. The power button works because I am here typing to you :D

If the PC is running fine you have nothing to worry about. Maybe the case had a green led light that has failed. Or maybe there is a cooling fan that put out a green light that you haven't plugged in. Or maybe the light on a cooling fan has failed thus no more green light. I wouldn't worry about it but check all your cooling fans.
