Computer will not come on after shutdown. may take 12 15 hour

Check hose going to M.A.P. sensor not broken both ends or cracked.

At this point you'll want to hard boot the computer and hope it completes when you power it back on.

Hold the power button down for 5-7 seconds and the computer should lose power. Leave it off for 30 seconds and then power it back on. It should resume the updating again.

I don't understand the problem.do you wan't the computer shutdown for 5 minutes or hours.then restart remotly or what.you have to give more information more information please.

did you tried reinstallation...i think your problem will solve by a reinstallation with a new disc..i experienced a problem before somthing like this..

For the monitor that is more than 2 years old, first place to look will be the power supply, look for bad caps with bulging top first, post back what you see inside so we can guide you further, see example of failed monitors due to bad caps; http://s807.photobucket.com/home/budm/allalbums

You can end the Not Responding Application to task manager, just press ctrl+alt+del then click on task manager, or ctrl+shift+esc to go there directly, click on task that is not responding then click on End Task.

If you want to shutdown your computer that froze just press on the power button of your computer for 10 seconds or more to force it to shutdown.

get a program called tweakui and tell it to shut down you computer faster.

Call oreilly's they have a code book on hand

It might be a problem with the computer. I would advise going back to where you bought it and returning it to either get a new one or a different one. Glad I Helped!
