    Do you hear a beeping sound when you open the computer? .
    usually that indicates where the main problem is.

    You can try reseating the memory on it.
    Check the cables inside it might be loose.
    also check you video card.

I have a Dell 530s Desktop. When I turned it on I get a Dell splash screen then it goes black. I can not even get anything to work thru the USB outlet. What could cause this


Have you check the BIOS if the harddrive is detected? You may want to use a working harddrive and check if harddrive cable is not loose or you can try to boot to a bootable disc just to isolate the issue.

Hope this helps.

System unit led is yellow and start good condiotion but no signal

The light on the LCD screen stays yellow?

I would start with puling out the ram chips and see if it works,

If you get some beeps and video works with ram chips out, then its a bad ram chip.

If thats not it.. unplug all cards cd/dvd rom and harddrive to test motherboard and CPU chip. see if you can get video to work with everthing but cpu and power suppy unpuged

Screen does not turn on but green light is on.

Green light indicates the monitor is getting power. Nothing coming up on the screen indicates, No Signal.

No signal from the computer. This means the computer itself isn't working.

A bad power supply in the computer can cause this. A bad power supply is the leading cause of desktop computer failure. It is replaceable, and can be done by the owner relatively easy.

You may have a computer tower that the Power light comes on, you hear fan/s spinning, (Including the Power Supply fan), and it sounds like the harddrive is running.

ALL the lights in your computer use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
A harddrive sitting there spinning in an endless loop, consumes about 2 to 3 Watts.

A Processor uses 51 to 125 Watts. Depends on what Processor it is.

A weak Power Supply will have enough power for lights, fans, and that harddrive sitting there spinning.
It won't have enough power to turn on the Processor.

[No processor operating, then the harddrive sits there spinning in an endless loop, because there is no processor to find the boot sector]

For a test, connect your monitor to a know good computer. See if it works.
Now connect that other monitor to your computer.

When i turn on my computer it works perfectly fine apart from the srcreen is not picking up my signal ive tried the screen on another pc it works fine and im not sure what ive got to do.

Try disconnecting power......reseat the video card, unless it is onboard. If it is on board video then the mother board is garbage. You can insert a 3rd party video card and try that and see how it works.
