SOURCE: dell gx 520 long beeps and unable boot display?What's your problem?

Usually the beeps ore associated with ram memory failure ..or video card not being well plugged or being faulty ..To stat check the ram memory ..Just remove them all ..(if you have more modules) ..and after that insert one by one and try to boot ..If it still makes the same noise (beep ) and each one means the ram is ok ..and the fault from other way ..If it starts with only one one means the other is faulty ..Anyway ..usually the ram memory does not damage itself ..but most likely does not make contact well plug them well back in the slot and try again ..
If it always make that beep ..try to see if you have a pci or agp or video card ..and if you do ..remove the card and post it back ..Usually if you remove it and you have a on board card can already boot up if the card is faulty ..and use the card on board until you get another card ..
(the idea is that for the ram fault the beep is short and in some kinda loop ..but if it starts the fan and keep beeping it is the video card to blame .It is either out of slot and does not making contact well or is damaged and need to be replaced.

It is dell optiplex 755 ,when i on my pc it freeze after a certain seconds & not display to the monitor.

Do you have a good working monitor that you can troubleshoot with? I would make sure the monitor isn't going bad first. Then if you're still having the same issue, try re-booting in safe mode and run a virus scan.

you should replace the motherboard or the power supply of your computer. to determine which one to replace is a simple test. disconnect all that is connected to the motherboard and if the problem is still there, then the problem is the motherboard.

Few days back, when i switched on my pc, just fan starts with noise.. i turned it off then on.. it was working fine, but next morning when i switched it on again.. it was dead, no starting no light...

Check your motherboard for capacitor failure, the Dell Optiplex GX270, GX520, GX620, GX745 and GX755 units are know to have problems. When the machines were under warranty Dell would replace the motherboards because of this issue but they are not covered any longer. If you can solder then you can repair your board. Here is a link to an article that shows what to look for and how to repair the problem.

I hope this helps you, if so please rate my solution.

I have a Dell Inspiron 6000 laptop computer and I'm experiencing a problem with the orange battery light flickering continuouslyl; though the green battery light is displayed. Thank you

I think you may be referring to the green power light and the orange hard drive activity should have a power icon located on the bottom bar on the desktop near the clock that indicates battery power.
