Question about Computers & Internet

Open Question

Dell optiplex 760 is making 3 low beeping noises for no apparent reason. They are quick and the middle tone is higher than the other two. I can't seem to figure out what it means or how to fix it. No error codes.

SOURCE: WHAT DOES THIS NOISE MEAN?

When disk does a noise like click click, that meant the hard drive heads are broken. Harddrive hardware is broken, data cannot be recover easily when it is like that , if the HDD contained very imprtant data you can send it an HDD data recovery.
Here is an HDD data recovery company in uk

This is the picture of a broken head:

SOURCE: Dell GX150 beeps 5 times on startup.

This normally means there is a memory error. Have you recently added memory to the sytem? You can try to remove and reseat all memory modules in the system to see if that clears the problem.

SOURCE: dell optiplex 760 won't go into safe mode

It sounds as though your PF keys are disabled by the BIOS settings. Try this:
Upon cold start or reboot get to the BIOS setup. You may have to press F2 or delete, or whatever key the first POST messages instruct you to use. Different BIOS manufacturers use different keys, and you have to be quick to interrupt the boot process using the correct key. If you fail to determine what key it is, reboot once again, until you see/read what key does the job.
Next, once you're into the setup screens, look for a section where you can set/deny access to the F8, F9, F10 etc keys during the boot process.
Make sure you ENABLE them, following the instructions on what keys to use to set/reset these choices. Make sure you SAVE AND EXIT.
On the next reboot, upon the disappearance of all POST messages, make sure you press the F8 key repeatedly until you see your OS boot options menu, among which you'll find Safe Mode.
Good luck!

My Dell Optiplex GX620 is making a soft beeping noise like an alarm. Why?


It in fact may be an alarm, over heating?
If it beeps in groups, like TVs do in an error mode, look up what it means on dell's web site.

I could not find any product that would fit a SFF case. The best suggestion i have for you is to get the riser card adapter that will fit standard PCI cards in the Dell Optiplex 7xx models. here is the link and partial discription.

The Dual Full Height Riser from Dell™ enables you to fit two PCI card in its slots. This product has been tested and validated on Dell systems and is supported by Dell Technical Support when used with a Dell.
