    Hello,

    Try disconnecting everything not necessary including soundcards, cd/dvd drives and hard drives. This sounds like a videocard or hard drive issue but we want to eliminate everything.

    Do you even see the bios screen flash on?
    Does your monitor show anything when it first turns on?
    Will it boot to a cd?
    Do you have a boot disk?
    Does that work when everything is disco'ed except the CD Drive?
    Is there any beep sequence?

    Is the video card onboard or add on? Can you try the HD in another PC?
    Can you try the video card in another pc?

    Thanks,

    B

This could be a heat issue but more likely hardware. You need another pc to start testing out the parts individually. That is the only way to verify for sure what is going on.

I would say this is a hardware issue. nothing anyone online can do for you with this type of issue unless you recently chaged something.

Optiplex SX270 LED light code


Hello

The LED code you described indicates a memory failure. Remove and re-install all of your memory. If this does not fix the issue, remove all memory and insert one stick at a time until the unit turns on. Replace faulty memory.

Here is the LED Code guide from Dell...

DELL SX270 WILL NOT COME ON HAVE LITE INSIDE PC


the power supply is probably bad. It's really hard to tell without a little more information. When my power supply went bad on my computer. the hdd light would come on but nothing else and the computer would not even try to start.the power supply puts out several different voltages with both positive and negative outputs.

I have a dell sx270 desktop when I plug it in only the fan works


First of all, keep the front button pressed until the system shuts off. It might be one of several causes:
1) Memory module damaged (or dirty)
2) The processor is damaged, or
3) The motherboard parted off.
Remove the memory modules and test them one by one. Or if you can test them in another PC (assuming both PCs use the same kind of modules).

  1. Boot up the computer into the setup (depending on your bios, to get into the bios you need to hit the DEL key during boot up.)
  2. Press 'ALT' and 'F' at the same time
  3. Turn 'NUM LOCK', 'SCROLL LOCK' and 'CAPS LOCK' on. (Make sure the lights on the keyboard are on.)

Orange led on mother board


You have a hardware failure, most likely memory or video card. The first thing I would try is open the case and blow the dust out of it, especially dust on the memory modules and anywhere on the motherboard. Then try to boot the computer again. If that does not work I would start removing components one at a time and testing them.
