My computer will not power up but the LED on the MB's lite up.
I just build a computer two weeks ago and I try to add another HD but after add that HD and removed. Now my computer does not power up, even the power switch is dead, but the LED of the MB still lite up. Please help
Re: My computer will not power up but the LED on the MB's...
I think that case is m/b crash. so u do first remove all power connector in your m/b and in later 3 minutes u can put all power connector in your board. All connected in ur board so u run your system firstly hear " te ", That is clear for your problem. But
u don't hear press key in checking ur screen in m/b BIOS setup key. i cann't tell exactly because BIOS setup is many different but any configure u can do that for example: LOAD SYSTEM FIALD or System Performance...
Ok i wish u do that and slove your problem...

It seems to me that your motherboard may be on it's way out. Those seem like some of the signs when the MB is in it's death throes. Or make sure your system isn't dusty or in a moist area. Could be your power supply isn't high enough. I'm going with motherboard though.
The first thing you should do is remove the video card and try to boot
the PC using the onboard video (video on the Motherboard) and see if
that solves the problem. If it does, try putting the video card back
in in a DIFFERENT PCI slot and try it again. Sometimes Windows loses
its marbles about
cards inserted into PCI slots. My nieces eMachine loses its marbles
over the Wireless LAN card about once a year, so I just move it to a
different slot (swap it with the phone modem card). If that makes it
flaky again, try updating the video card drivers. If it doesn't help,
your video card is shot.
If it isn't the video card, try taking out one memory chip at a time and booting with the
first one in. If that doesn't do it, swap the memory chip with the
other one and try booting it again. If needed, replace bad chips....
After that, it is probably the power supply or the MB itself. Swap out
the power supply first. If it is not the power supply, then it is
probably the MB, and you are SOL.
THe GX280 had 2 sets of LEDs that provide information on the POST. First is the POWER LED, if it is Solid Amber or Flashing Amber then there is a MB or Power issue.
The othre indicators are on the BACK near the PS2 ports, 4 LEDs Marked ABCD. These LEDs normally cycles then stop all 4 green (GGGG indication) if they stop in a different configuration (AAGG is a memory issue for example) then that can clue you in to the fault.
From the basic description, I'd say the MB has failed.
Does the hdd lite come on? cd lite come on? The blinking lite on the power is an indication the bios or power supply is having trouble. strip the unit of all devices except hd, kb and use the vga built in video. Remove the ram also. restart and see what happens.
