Blue light on new PC build? PSU?

[Chase R]

Hi, is there any recommendations of what to do if I get the blue led on my mobo? I heard it was a psu problem but I just used it in my old rig last night... My psu is cx750m, I know it is bad but I don't know how it doesn't work a day later.

Without the system specs inclusing the make and model of the motherboard there is no way to answer this. You need to provide more information.

The manual makes no mention of it being a diagnostic LED so it more than likely just a flea power led. If the psu is connected and turned on this light should be on.
