How to reboot dell E173FP??

OK, what do you mean, "Won't let me" What exactly is happening in the process?

Your dell could have been attacked by a virus or malware, and it went on to replace some system files. your options are, to reinstall the operating system, my guess is you are using windows, so reinstall windows, whether xp, vista or 7, login in using service directory repair mode, that is, by pressing F8 after the dell splash screen has displayed upon powering the computer, and selecting that choice. once logged in, perform virus scan if you have a good antivirus. meanwhile copy your important files and documents to a removable drive. if the antivirus manages to clean out the virus. you can reboot in a normal mode.
the second option is to use a live cd if you have ever heard of one, boot your computer using the live cd, some common ones are hiren's boot cd, multi-boot recovery cd and any other that you might across. once logged in, copy your importnt files and documents into a removable drive and format your computer and perfom a clean installation, this time do not forget to purchase an antivirus and install, kaspersky is fairly good, for some free options, avast is a good option. then scan your removable drive and clean it for viruses before recovering your documents

Here you go!
From Dell website:
'OSD Lock': Controls user access to adjustments. When 'Yes' (+) is selected, no user adjustments are allowed. All buttons are locked except the menu button.
All buttons can be locked or unlocked when the 'Menu' button is pushed and held for over 15 seconds. See more here:

several reasons why this will occur:

1) battery is not fully charged - you might try rebooting with the computer plugged into a wall socket.

2) computer's main power supply has been damaged and needs to be replaced.

3) virus - though with most standard virus' , you can still boot up, there are a nasty few that will wipe your entire computer including the operating system.

Restart the computer and turn off power save mode. If this is vista the power save mode has a lot of problems and can cause things like this to happen.

the monitor has the ability to attach a sound bar (AX510) the power connection is for the add on speakers

There should be a disk that says something about system restore.Put that cd in the drive, reboot the system and follow the prompts. It will restore to the factory defaults.

The file “Windows/System/Drivers/mup.sys” is not actually causing the problem. It’s the next step after mup.sys that’s causing the computer to hang. That next step consists of the OS checking the registry files for plug and play devices.
Some causes are: new or defective hardware installed, corrupted registry, (caused by virus), defective or corrupted hard drive, just to name a few.
Try removing all devices attached to the computer like printer, web cam, flash drives, etc.
If your computer has a PCI or AGP graphics card AND your motherbrd has a VGA connector, remove the video card and use the one on the motherbrd.
If the above doesn’t work, try running “CHKDSK /P” from the Windows recovery console.

HI,
Are you putting in the Dell color monitor Cd to install the monitor ?
The new computer should not require,any drivers as its plug and play


Thanks

presuming you have a Dell PC go to http://support.dell.com/

Click drivers and downloads and enter the tag number. This is usually 7 characters long and on a sticker on your Computer Tower, it clearly states tag

Now look for Monitor, video and chipset drivers

download and install the latest versions of these.
