20 Most Recent HP Media Center m7260n (EG642AA) PC Desktop Questions & Answers

The HP m7260n has an SPDIF connection on the motherboard. It's near the spot where the VGA port is connected to the board. I suspect that is what you need. The layout diagram for the P5LP-LE is available here: https://support.hp.com/us-en/document/c00864946 .

The specifications, including the motherboard information, for the m7260n are available here: https://support.hp.com/us-en/document/c00507225 .

I hope this helps.

A computer not powering on could be a large amount of things.
Try these things first.

  2. Re-seat the RAM modules.
Attempt powering on the computer, with a DIFFERENT PSU (power supply unit)

Post back with results.

Anytime you have problems like this, you need to make sure to check the basics first. Are the wall outlet and power cord both good? Plug another electrical device into the outlet to make sure it is working, and try connecting the computer with another cord.
Now that we know that there is power to the computer, look for any lights on the computer when you press the start button. Also look for any fan motion. A common problem with a faulty motherboard is that as soon as you press the start button, the power supply fan with try to spin, but will immediately lose power. Do you smell an "burning" type odors coming from the power supply? If so, you probably have a bad power supply.
At this point, you have to decide if you want to repair or replace you system. If you are truly running a pc with XP or Vista, you may want to consider upgrading to a new system. Your hard drives in your old system are probably okay, and if you purchase a new system, the drive may not be compatible with the new hardware. Older systems typically used IDE interface for hard drives whereas current systems mostly use SATA. The connectors, both power and data, are not compatible. You can purchase an external adapter which will allow you to connect your older hard drive to the newer system via USB, but you will have to re-install all of your older programs on the new machine, and hopefully, they will run on the new operating system. There should be no problems migrating your data files, music, photos, documents, etc. to the new machine.

I understand your problem. As you have added a new video card and do not have video when you try to boot up, are your trying both the upper case connection to see if the video is still being outputed from the original VGA source?

I would suggest that you reboot and go to BIOS, to see if your on-board video is still enabled.
I you can access your BIOS settings by pressing F2 or F6 upon bootup.

Good Luck

If it happens that you are prompted by the following error message "DISK BOOT FAILURE INSERT SYSTEM DISK AND PRESS ENTER", "No system disk", it means that the computer did not find the operating system to start (boot).


A diskette or CD has remained in the drive

Check out if any diskettes, CD-ROM or DVD-ROM are present in respective drives, remove them and restart your computer

The boot sequence is incorrect BIOS

Enter the BIOS setup of your computer and edit the boot (boot sequence) so that the computer starts primarily on drive C:
A new hard drive was installed

In the case that a new hard drive has been installed, this message is quite normal.
Just insert the correct CD to install the system (usually Windows), then restart, while making sure the CD-ROM is first in the defined in the BIOS setup as first boot sequence.
The hard drive is unplugged

Open the system unit and check that power cable of the hard drive is properly connected.
Corrupted system files

It may happens that some system files needed to boot the computer have been deleted /damaged or that the boot sector of the disc is damaged.

To determine this, start the computer with a system disk or CD-ROM installation of Windows (via the Recovery Console), and once started, type Dir C: to check if the contents of drive C: are accessible. If its ok then the problem comes from missing or damaged files, then you just have to run the command:

fdisk /mbr
sys c:

Note that before any restoration of the boot sector with the command fdisk / mbr, (supposing that there is a virus), it is recommended to use an antivirus running under DOS, such as
Damaged disk

If the hard disk or a partition is damaged:
If it detected in the BIOS setup, there is a chance that it is
not out of service.
If it is, try reinstalling the system through the installation CD, in order to reformat or recover the partition using a utility.

your harddrive has become corrupt you will need to find windows xp vista or windows 7 which ever you use on your system

You might need to uninstall the old video card device, so Windows does not use the old drivers for the new card.
Another option is to try and boot in Safe Mode (press F8 during startup), so Windows uses the VGA mode (which all video cards support), and then install the proper driver.
Installing the latest ATI driver updates might also not be a bad step.

SP3 issue. you can uninstall SP3 and then hide it so that you will continue to receive other updates. Every 2 weeks you should unhide it and try another install. If problem persists you may need to reinstall OS from disk. Follow directions closely so that you won't loose any files.
