SOURCE: Dell Optiplex GX280 boot problem

I just repaired two Gateway systems with similar behavior (turn on power, fan runs at full speed, no boot), and both needed replacement system boards. (These were a different model, but the symptoms are typical of a dead system board.) I got the boards from a company called Blue Raven Technology (www.blueraven.com).

Before deciding the main board is bad, try another power supply to make sure that's not the problem. Also you might try clearing the CMOS memory on the system board (either by moving a jumper usually found near the backup battery, or by removing the battery itself). Sometimes corrupted CMOS data will keep the system from booting.

You may have a problem with your power supply(the loud fan noise) and eventually it may get too hot and will cause problems like not fully booting.

SOURCE: I HAVE DELL OPTIPLEX 780 DESK TOP WORKSTATION ,THE CD DRIVE IS NOT SHOWN WHEN I OPEN IT



make sure all leads that are attached to your cd/dvd have secure connections and are not faulty or just replace them they could be faulty ?

you might have to physically unplug the cd/dvd drive restart your computer this should activate the found new hardware wizard

Click start control panel administrive tools,computer management,device manager scroll down cd-dvd rom drives you might see a yellow question mark ? right click you will have options to update driver,roll back driver,or select properties general troubleshoot, select driver click to reinstall drivers click update driver or uninstall then reinstall if this does not fix the problem it might be a registry problem if you cant see your disk drive in windows explorer

Close all open programs

Click on Start, Run, and type regedit and press Enter
Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE

SYSTEM

CurrentControlSet

Control

Class

{4D36E965-E325-11CE-BFC1-08002BE10318}

This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

Upper Filters

Lower Filters

Upper Filters.bak

Lower Filters.bak
If any of the above keys shown in step 4 are listed, right-click on them and choose Delete

After deleting the keys, close the registry editor
Reboot your computer

Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.


hope this helps you

Making rattling sound Dell OptiPlex 780


It could be a fan making the noise. Either a fan is going bad, possibly a bearing or bushing. It could just be a wire that got too close to a fan and the blade hits the wire.

Dell OptiPlex 780 with Windows 7 does not play my cd's or dvd's and is missing from device manager


Sounds like a problem of non-detection by the system. If the drive is missing from My Computer then it definitely is a non-detection issue. Try using this file (it's an exe when unzipped) and only required double-clicking.
