Bought new hp computer,with Vista,the cx6400 will not run.. Makes strange noises, then shuts down.. noises include clicking,and slight squealing.noise lasts about 3 sec. [email protected] Unit is approx. 4 yrs. old, bought it new. Finally located the disc that came with it, Will try that...?

Check the pinion gear and the ring gear, most probably they are not messing right....or get it to a mechanic to check that out!

If it's new i would take it back and ask them to check it out or even replace it if needed.

It's the DVD Player. Demand a new one. Go here. Expect some run around and difficulty getting it resolved.

Good Luck.

When you say it shuts down, does it simply turn off straight away? If so I would say it has a faulty power connection. If it goes through the whole 'Windows is shutting down' processes then it maybe the motherboard which is faulty. Either way it sounds like quite a serious issue.

Sounds Like Video Failure...
If you were Gaming On THat Laptop, You Probably Overstressed The Graphics Chip/GPU..

Other things that would cause the shut downs would be, Incorrect or Faulty AC Adapter, Make sure you use a 19.5v 90Watt.. Not the 65 Watt..

Failing or Bad Ram, Misseated RAM... Open port to RAM on underside of laptop, Pull The RAM and reseat it..

Make sure Hard Drive (s) are securely seated..

try shutting it down and restarting the computer shut it down for about 5-10 minutes then restart it when u shut it off unplug the keyboard and just before you restart the computer plug in the keyboard

Hi, Most of the times, windows Vista has the drivers required for the printer. The problem is that sometimes it could be bugged. I strongly suggest that you install the HP drivers from the Hp.com website (install CDs would do the trick) Be sure you install the Windows Vista drivers and it should show up just fine. If you are already using the latest drivers from HP let me know.

try using a different monitor, borrow one if you have to, if the monitor works on your computer, then it simply means you need a new monitor. As far as the computer shutting down, it may be recording the bad monitor as an error in the loading process and automatically shutting down.

remove all the drivers from add and remove program then

Make backup of you registry, then on left side drill down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors
