Dell optiplex sx270: loud, steady noise like an alarm a few seconds after I turn on the PC


You can check the meanings of the error beep codes HERE. Every beep code means something different. The bad thing is that the code I think you are speaking of is a fatal error.

Good luck

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...

My dell sx270 optiplex doesnt powerup somtimes after i unplug power supply


Chances are it's going to be slightly oxidized contacts on a supply part, but it's not broken, just intermittent. Some power supplies use relays to supply the voltage, and their contacts can get oxidized. The fix for this is to take it off it's mounting, open it up, and use paper or a very fine emery cloth to clean the contacts. You can also change the relay, if that doesn't work out. It's not something that will hurt your computer, just a nuisance.

Re-installed windows xp on dell optiplex SX270 and i've no sound


Begin by checking device manager. If there is a Unknown device or PCI device listed but not properly installed you will need to identify your audio chipset and downlaod and install the correct driver. 90% of all onboard audio chipsets are AC 97' by Realtek.

If you need help in locating the drivers just post back.
