I've checked your media center model on the net and it appears to be a known BIOS problem. Keep in mind that this is most likely video card or motherboard failure. But we can try resetting it Try booting into the BIOS using the F10 key and then pressing F12 and pressing y. The system should reboot with the default BIOS settings. If there is any change you likely have a good chance at fixing it. Please post your results.

Hi,
This often happens during a storm and usually is quite an easy fix.
Remove the power cord, from the back of the computer, with the back of the computer facing towards you, on the right hand side there should be 2 screws top and bottom, remove these screws and take off the side panel.
Inside the case, on the motherboard you will see a large battery, take that battery out and leave it out for 30 minutes.
Now, remove the system memory, the memory will look like this >>>>>


Just unclip the memory, get a clean, dry, soft paintbrush and clean the brass contacts on the memory with that.
If there is any dust on the slots that you took the memory out of clean them also.
Wait for 30 minutes, reinsert the memory making sure it clips into place properly, put back the battery, the side panel, the power cord and power the machine on.
When the system boots up you will get a CMOS error, don't worry about that just go into the BIOS and set the time and date, save the changes and exit the bios, the computer will restart and hopefully boot into Windows.
If you need anymore advice please post back.


Good luck.

SOURCE: HP m7060n Media Center PC had boot problem: now won't display any

Lets try to repair it using the windows installation disc. First things first, look at the motherboard down on the right lower side. I would like you to find the CMOS jumper, it will be three pins sticking up with a plastic jumper made of plastic fit over two of the pins. I would like you to move the plastic jumper over one pin so it "shorts" the next pin over. Now power the computer up and lets see if it boots to BIOS by tapping F2 during the initial power up and splash screen...if it shows it. If it does get into the bios, go to the save page and click on "set default settings", click F10, save and exit. Power down the computer, unplug it, press in the power button for 10 seconds. This will now drain all power out of the system. Move the plastic jumper back to its original position. Plug the computer back in and power it up, go into the bios....if you are in, reset the time and date. Reboot with the windows installation disc in a drive you know works. Follow the repair fix listed below. Follow it closely, it will repair most boot errors.....

Windows Start-up Errors
Step one, you need a Windows Installation CD. If you only have a recovery disk set like the ones from HP or Compaq they will not do what you need done. Under normal circumstances however, you can use a Dell disk because the Operating system is on a stand-alone disk. All retail versions are also acceptable as well as upgrade disks. For a rule of thumb, if the disk has the Microsoft hologram it should work.
While the computer is first starting up and you see the manufacturers splash screen, tap F12 (some computers it’s F9, others it may be another key, you may have to watch and see if the computer lists the key strokes for getting to the boot menu. If you still cannot find it, boot into the BIOS settings and change your boot order there. Save your settings and exit, the computer will now seek the cd rom as its boot source first.
Place your Windows disk in the computer and start it up. When you see the test at the top of the page “Press Any Key To Boot From CD” Just hit the space bar to activate. The next screen you will see will most likely be a Windows setup screen, when you see this press the “R” key to get to the recovery console. It will get there, it may take a little time, patience. Once it loads you will be given a choice of Windows installations, there should only be one, if there are more, always pick number one. It may ask for an administrators password, if you have not set this particular password, then just leave it blank and press enter. The next prompt you see is:
C:\Windows>
You need to type the following:
cd \
hit enter. Pay close attention to the spacing between the characters. There is a space between the character “d” and the “\”
You are now at the ROOT of the drive, this is where basic commands can be given and changed. You should now see the following:
C:\>
Now type the following:
CHKDSK /R
Hit the enter key.
The chkdsk /r command also includes the P command and will also look for lost recoverable information in bad sectors.
There are occasions depending on how corrupt the system is, that this process could take several hours, so be patient with it.
Now, after chkdsk has run type the following:
FIXBOOT
Hit the enter key.
It may prompt you with a warning, that’s ok, just continue. When fixboot has finished, type: EXIT hit enter and windows will reboot. When the system reboots, tap the F8 key during this time and you will see the multi-boot menu come up. Scroll to the title “Last Know Good Configuration” and hit the enter key. If you were having some simple drive errors this should have fixed them.

if you download and install tune up 2010, it may fix your registry automatically for you however if it fails to, your operating system will continue to fail to shutdown. Device drivers are very well known for causing this error and if you have installed a new device and your computer is not picking up the new device properly, then the computer will not shut down. There are several forms of viruses that cause the system to stay on, power problems may cause the system to crash during a storm and thus damage the computer registry. A system defragmentation, cleanup, along with a registry clean would be the first best ideas.
