That's pretty crazy! I would have told you to turn the printer off, and unplug it from power. Same thing with the computer. Then follow a few basic procedures.

Better grab a cup of coffee, this is going to be a long one.

I have no idea what changes, the 'tech' implemented on your computer. Would have to undo what the 'tech' did step by step.

I do know one thing, however. Using the Restoration Disk/s, is not going to fix Adobe CS4.

We'll have to go step by step. I can only guide you if you have Windows Vista. (The HP Pavilion Elite e9180t is also offered with Windows 7)

Ready?

Printer:

Printer off, unplugged from power. USB cable unplugged from computer side.

You need to go to Control Panel>Add/Remove Programs.
(Left-click on the Windows start button, then click on Control Panel. In Control Panel click on Add/Remove Programs)

When Add/Remove Programs loads, find the HP OfficeJet software listed. Go to the right, and left-click on Remove.

If it asks, 'Do you wish to restart your computer?', the answer is NO.
Close Add/Remove Programs. Close Control Panel. Go back to your desktop screen.
Shut your computer down normally.

Unplug the computer from power. Press the Power On button in, and hold it in for a count of at least Five seconds. Let go of the Power On button.
Do this procedure two more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS back to the factory default settings. (No, do not take the CMOS battery out)

Now plug the computer back into power. WAIT 1 minute. Turn the computer on. Let Windows load all the way.

Install the installation CD for the OfficeJet printer, into your DVD drive. Install the software. If it asks you to restart your computer, go ahead, and do so.

After Windows has fully loaded again, plug the USB cable of the printer into the computer. Turn the printer on. You should get a message out of your system tray.
'Found New Hardware', and perhaps another one,
'Found Officejet printer'.

You should now have your printer back online.

Quicktime:
Go to Add/Remove Programs, Click on Change.
In the options given, click on Repair.
If this doesn't do it, go back to Add/Remove Programs, and - Remove, Quicktime. Now go to Apple - Quicktime - Download, and download the newest version for Windows Vista.

(If you need help with this, let me know)

Will add more in additional comments section.

Go to control panel---> Add remove programes---> uninstall the entire HP installation. Restart the system. the message will not come.

If u want to install the HP image again then, reinstall it fresh from the HP CD.

You can remove the Dell support from your add/remove programs. This support is installed on all Dell systems in factory. Once your warranty runs out, it is pretty worthless because you still have to pay for support.

Go to start, control panel and click on add/remove programs.

Look for Dell Support or help and uninstall it. Reboot computer and the error message will go away!

did you add any device recently or installed a program before this happened? If your response is yes, then take out the device and try to restart. else, retsrt your system and press the F8 key to show you the boot options. start the computer on safe mode, and remove the newly installed program or roll back the system to a safer date when your system had no problem. Cheers!
