Dell xps 710 motherboard replaced with 700 motherboard but it does not boot

This could be any number of problems. First start with hardware. Is everything seated and connected correctly? Are the hard drives installed correctly. Are the power on pins on the board set correctly or pinned at all? Is the ram the correct ram?

Check the hard drives, are they functional, do they boot with other computers?

Use a volt meter and check that the power supply is producing the correct voltages on all the connectors and rails.

If that all checks out, it might be a bios error. Check your boot load order and if the motherboard is detecting the hard drives, check that the correct bios settings for OS management are in place as this is a server. Is the RAM power settings (voltage) and speed correctly selected? Will the computer boot from optical drive using a live CD? Will it boot from a USB live OS (like Ubuntu)?

Since it's not booting, you may not have compatible hardware or damaged hardware. The OS that's installed on the hard drives may not be able to load on the new (older model) motherboard due to driver incompatibility.

If you have made any hardware changes, this could be problem, try to unplug new hardware.
If you have added new HDD or DVD drive, please double check the IDE drivers, as these cause this problem.

Power fan ok board not display processor not run

1. Make sure that the processor is correctly inserted into the slot. 2. Make sure that all the RAM modules (long sticks with little rectangles on them) are inserted correctly, and completely locked into place. 3. Make sure that the processors fan is working (if it overheats, it may have an auto function to turn off.) 4. Try removing the RAM modules one at a time and booting up. Could be a bad stick of ram preventing anything from showing. 5. Remove the processor, and boot up without it after clearing the cmos (should be a button on the motherboard, and if not, there are three pins with a little jumper on two of them that will say cmos near them, put the pin on the opposite far pin, and the middle one, then boot without the processor in, wait ten seconds, put everything back the way it was, then reboot. If all that fails, You've got me :S Good Luck

I'm doing my first system build. I have everything connected but it will not boot, fear I might not have MOBO wired correctly it is an Abit AN52. Any help would be great.

First off disconnect any devices connected to the board, hard drives, dvd-roms, leave the the memory, processor and power lead connected to the board, try to boot it up.
If the fans run then the power switch is wired up properly, next check the graphics, ensure it is in the socket properly and all power connections are connected up.
If it still dosent boot and you have the manual for the motherboard look for the bios jumber, there are 2 settings normal mode which lets the computer boot, and the other that dosent allow boot, this jumper is normally J12, but have a look in the manual for the motherboard to make sure, if you try all of this and the system still will not boot please post back

My power supply was running hot. came back some

It is possible that on occasion a bad power supply can also take out other stuff.

first of all double check each and every power connection and only connect the drives that are needed to actually boot up the machine.I cant pull the manual for this mobo right now so gonna go out on a limb and say check that the 24 pin (could be 20) is inserted correctly and all the way, same for the four pin square and the 6 pin oblong (may be optional on the 6 pin)

Double check the flying leads the go to the front of the machine just in case one of them has become disconnected make sure that if you have had those off that they went back on correctly as some may need the correct polarity to work. refer to your manual if you are not sure.

Try again.

Even new psu's can be bad so maybe get the shop you bought it from to check it for you its a 2 second deal if they have a PSU tester (if they don't then maybe they are not quite the shop you would want to get a PSU from) If the PSU checks out then you could try start with a new mobo but there is still a chance other items got pooched too

Hard call as to a new mobo and maybe the rest

Intel D845GBV will not boot into Operating System ,Win XP Pro

Still have that Windows XP Pro full installation disk, that you used for this harddrive?

Make sure all power cables from the power supply are connected.
You have a motherboard, (Intel D845GBV), that has a Socket 478 processor socket, and uses Intel Pentium 4 processors.

Computer Unplugged from power! Touch the metal frame of the computer case to relieve your body of static. Work on a table. IF you get up for any reason, then return, Make Sure you touch the metal frame, BEFORE you reach inside.

1.Make SURE the 4-pin ATX power cable from the power supply, is plugged into the 12 volt ATX connector on the motherboard.

[12 volt ATX connector on motherboard:
Bottom LEFT corner of the processor socket. You are looking at the motherboard with the processor at the top, and the ram slots to the right]

2.Make sure the 40-pin flat ribbon interface cable, is plugged into the harddrive correctly.

There is a faint red stripe along one edge of this flat ribbon cable. The red stripe designates Number 1 pin. (There are 40 pins on the back of the harddrive. [39 actually. One pin is blocked out]

As you view the back of the harddrive, the 4-pin Molex power cable, plugs into the right side. (All the way to the right)
The 40-pin flat ribbon cable plugs in to the left of the power cable.

Number 1 pin of the flat ribbon cable, is next to the power cable connection.

The red stripe, will now be close to the power cable connection on the harddrive, when the flat ribbon cable is plugged in correctly.

3.Make sure the 4-pin Molex power cable is plugged in firmly into the harddrive.

4.Check all power cables to the optical drive/s, and the main power cable to the motherboard.
[20-pin ATX power cable. To the right of the ram slots]
Now, close the computer case, plug the computer back into power, WAIT 1 minute, turn the computer on.

As SOON as the POST screen goes by, start tapping on the F2 key. You are going into BIOS Setup.

You should now be on the main menu in BIOS Setup. You can no longer use your mouse, you have to use your keyboard to get around in BIOS Setup.

At the top you will see headings in the header bar. Maintenance, Main, Advanced, Security, Power, Boot, and Exit.
Use the Right Arrow key and highlight Boot.
Press the Enter key.

Use the Down Arrow key and highlight Boot Device Priority in the drop down submenu. Press the Enter key.

Use the Down Arrow key and highlight ATAPI CD-ROM. Press the Enter key.

Now press the F10 key.
If Yes/No comes up, use the appropriate Side Arrow key, (Left or Right), and highlight YES. Press the Enter key.

IF Y/N comes up, press the y key for YES.
(It isn't a capital Y. The capital Y is shown for clarity. Do Not press the Shift key, and the y key. Just press the y key)
Now press the Enter key.

(F10 is to Save Changes. Y is Yes you want to save changes. The Enter key executes the command)

Your computer will now restart. You need to have that full installation disk in your optical drive. (CD/DVD drive)
Your computer will now boot from the full installation disk in your optical drive.

If your computer goes past booting from the installation disk, because you did not get it in there in time, don't worry.

Just press the CTRL key, ALT key, and DELete key, AT THE SAME TIME. (Not shouting)
This will restart your computer, and it will boot from the Windows full installation disk.
