About the only thing I can think might be happening is that your computer is trying to turn on because of network activity, but it's not succeeding. Most motherboards with integrated network interfaces support "wake on LAN", which lets the PC start up if its network connection becomes active. Check your BIOS settings, and disable the wake on LAN. I don't know for sure where in the BIOS pages it is or exactly what it's called, but you'll find the setting there. (I'm not home now, but I have a GX series machine I will hook up later and check. I will post a follow-up with more details about the BIOS settings. Now I'm curious.)

Sad to say, you need a hard drive. The clicking sound you're hearing is typical of a drive that has gone bad. The monitoring message you see is from the motherboard's SMART monitoring, which checks several drive parameters and tells you when something is out of normal range. Often this gives some advance warning of a drive going bad, but this time it's just another sign the drive is already bad.

Installing a new hard drive is quite simple, with only two cables to plug in and some screws holding the drive in place. You will need to reinstall Windows and your applications since the new drive will be blank. There isn't anything you can do to repair the bad drive. If you have data on the drive that you don't have backed up on some other medium and you must have, there are companies that offer data recovery services. Just be aware it can be expensive.

Sorry I can't give you better news, but thanks for using Fixya.

Make sure you have speakers switched on and connected to the GREEN socket on the computer. On the right of the taskbare, right click the little speaker Icon and open Volume Control. Make sure volumes are turned up on Volume control and Wave.

Are the speakers connected? Or perhaps it's an activation issue. Try looking in control panel, hardware and sound, then sound, and make sure your speakers are activated and your computer is feeding audio to them! =]

Yes, your hard drive is going bad but before concluding that your hdd is already bad do this first download hard disk sentinel and install it on your pc.

after you have downloaded and install the program run a series of test on it. then if you find that the hard drive is already faulty then its about time to replace it

Make sure your ehternet cable from the computer is plug into the lan port of the router. The setup won't start when the cable is plug into the wan.

Dell gx270 power switch


I don't think you need a new switch. The power "switch" on the front of computers today is a momentary action push button switch. Not a locking or clicking switch as older computers used to have.

Many of today's computers, including the gx270 / gx280 computers from Dell are really always on. You can see the green or yellow LEDs on the motherboards glow when they are "off" (like a sleep mode).

They are in a "sleep" mode until you push the power switch, which sends a momentary signal off to the motherboard to fully power up and turn itself "on".

I think you have something else happening here. When the system tries to power itself up, and detects a severe problem, it will try to automatically turn itself off.

The problem could be a bad motherboard, power supply, memory or processor. It could even be a failed hard disk that is drawing too much power (shorting out) from the supply.

If you had done something to the system, like move it or open it up for an upgrade, etc.. Look again at all the internal connections, and make sure there is nothing rattling around inside that might also be causing a short.

You could try removing all the PCI cards in the system, removing the power and data cable connections from all the disks (Floppy, Hard Disk, CD/DVD) and see if the bare motherboard (with CPU and memory) will boot by it self. If it does boot, then the problem was somewhere in those items and you can replace them one at a time until you find the problem, or if it all works again then it may have been a loose or bad connection.

If you have another machine available, you could try switching the power supplies and seeing if that is the problem.

Good luck!

Loud "jet engine taking off" type sound


If you changed out the power supply then the only other device that could be making that noise is your CPU cooling fan. To be sure, open the case and disconnect the CPU cooling fan plug from the motherbrd (MAKE SURE POWER IS OFF) and see if the noise stops. Don’t worry about the “Fan Failure Error” when you turn on the computer. Just hit F1 to continue. Don’t leave the computer running without the fan plugged in longer then necessary. After tying this procedure, please contact me for further diagnosis.
