Computer turns on, stays black

by DonJ_23 / March 28, 2013 11:38 AM PDT

I have not turned on my Dell desktop in over a month. Everything turns on but then the screen is just black. There's no Dell logo, nothing. But the monitor is on and it stays like that. What can be the issue? could it be the motherboard battery? If someone can help me please I would appreciate it. Thanks.

Some things to check
by wpgwpg / March 28, 2013 11:43 AM PDT

First check the cable and be sure it's securely connected to the PC and monitor. Next try booting to Safe Mode. If these don't help, get hold of a bootable DVD or CD and see if the monitor comes on when you boot from it. Bootable discs would include a Windows install disc, Windows repair disc, Ubuntu disc or flash drive, etc. If the monitor comes on with a bootable disc, you know your hardware's OK.

Good luck.

Re: Black Monitor

I'd reiterate what wpgwpg said in his post above, and also try another monitor. POST (Power On Self Test) appears to be completing normally, since the monitor is up and connected and running, but no video is displaying.

Make and model of your desktop would be relevant, as most Dell desktop models have an error code in the back of the computer that can be read; normal operation shows four green lights in a row. Errors will show one or more yellow lights. Depending on the sequence and order of the lights, a specific hardware fault can be found here:
