External parts of computer with definition? - Intel D865GBF Motherboard

Yes you can.
Insert the external hard drive into the USB port click on My Computer then right click on the external hard drive and select Format.

If you are talking about an external hard drive or external usb device that you put into one of the usb ports it might be bad. You could try a different usb port. Also try using it on another computer.

If it does not work on a different usb port or another computer then it's definitely bad.

Good job on the initial troubleshooting, heheh first thing I would have done is test an external.
This is going to be a bad screen most definitely.
You can buy OEM parts generally from Acer, but they will be 3 to 8 times as expensive as the parts on ebay.
Search " screen" and you should find parts for fairly cheap. The replacement can be a bit tricky though. Probably one of the hardest parts to replace I'd give it a 8 out of 10 for difficulty. If you can buy the entire lid (screen and plastic casing) and replace the whole top that easily drops the difficulty to maybe a 3 out of 10.

No, the files on the external disk-drive should be accessible when it's connected to the new computer.

First, buy an external storage device, at least 80GB (although it's currently difficult to find any _smaller_ size!) and make a file-by-file, folder-by-folder, backup of your 73GB of "data".

Second, buy another external storage device, and do a Google-search for "drive image freeware".
Pick one of those applications, and do a "image" backup to this second external storage device.

Third, disconnect the 3 "old" drives, carefully label them, and set them aside.

Fourth, connect the 3 "new" drives, delete the old RAID-5 array definition,
and create a new RAID-5 array definition.

Fifth, do an "image restore" from the second external storage device to the new array.

If you have any problems, all you need to do to "back-out" is to:
* disconnect the "new" drives
* reconnect the "old" drives
* delete the "new" array definition
* redefine the "old" array definition

and you're back to the "old" configuration.

Definitely there is nothing wrong with your with your computer but the LCD components only. If your computer still under warranty, I suggest you contact Dell Technical Support so you don't need to spend. However, if you are not sure go to http://support.dell .com ad provide your service tag which you can find underneath/bottom of your notebook. Please post your comment if the information provided has been helpful that could help move to the next rank and further improve my support assistance. Thank you and regards.

There is an internal switch inside the actual 3.5 mm headphone/speaker jack. When you have either headphones or speakers plugged in, it automatically switches to external. FYI: Macs are also notorious for getting 'stuck' in this mode (external) and I've had to walk numerous people through the steps to correct this. My Macs are definitely not excluded :) I hope this helps.

You are able to use an external hard drive as your main drive but you will need to boot it at startup. If you need more help then just ask

Attach your external HD with some other computer, that will definitely appear normal, the problem is due to a virus in ur HD. Your computer's antivirus software stops it to appear. Back up your data on the other computer, format ur external HD, remove un-necessary files and run a virus scan to the files u copied from HD, Hope this will solve the problem, if not, let me know and tell me what would be the response on the other compuer

you have to right click on "my computer", select "manager".. there you can find and select "disk management"
in disk management you can find every drive connected to your pc.

there you will also see your external drive, and you can start to identify the problem (maybe problem with drive letter allocation, filesystem type..). start by rightclicking in the row of your disk to use the contextual menu.
i know it's just a starting point.. but you definitely a need little more troubleshooting.
