Question about Intel DP43TF Motherboard

Open Question

CPU is not sending a video signal.

This started when reformatting a hard drive and installing an operating system on it (that's a separate problem that was fixed). This started once that was solved and everything was installed and loaded. Once I shut it off after that, it has not been sending a video signal to my monitor now. I thought it was hard drive, so I switched hard drives. I thought it was because of OS CD, so I took it out. I thought it was because CD/DVD-Rom drive, so I unplugged. I tried then unplugging everything for a while and replugging. I tried reseating everything and checking the connections. I tried switching monitors. I tried booting only the motherboard+video card + other essentials (no CD/DVD-drive or harddrive). I tried unseating one of my two RAM sticks. I also tried running it with just one of those sticks, then the other one. I tried the different settings for the motherboard of Normal/Configuration/Recovery. Nothing has been able to send out the video signal. Any help would be appreciated!

    While I was reading through the manual for the motherboard in hopes of discovering anything I may have bumped or missed, the video signal abruptly went through and the computer started loading.

    (^internet mess up, and don't see a button for delete/edit, sorry) I managed to install drivers for the graphics card and the motherboard, but then it auto-restarted... and I'm back to it not sending the video signal.

    Just adding in things as I go along and try them out... tried switching out the PSU and booting solely the motherboard (main pin and 2x2 on this board), still no signal.

    Power unplugged from computer. Anti-Static Precautions FOLLOWED, remove all ram memory modules, and clean the gold plated contact pins on the bottom. BOTH sides.Although there are solid polymer capacitors on the motherboard, (Little aluminum 'cans' with Blue mark on top), there are also Electrolytic Capacitors on the motherboard. (Radial Aluminum Electrolytic Capacitors) See if there are any visual signs of failure,

  • Michael Nov 05, 2012

    There are no visible leaning, leaking, or bulging capacitators.

  • Michael Nov 08, 2012

    Gently rubbing the golden plated contacts on the RAM provides no change. Also for additional info, booting up without RAM yields 3 short beeps.

It appears that you are aware of Motherboard jumpers.

1. Reset BIOS settings by CMOS Clear jumper ( Location of jumber is given on the sticker / manual of motherboard )

2. Try updating BIOS of your motherboard from the following link :

3. Plug only Optical Driver / Hard disk at a time and check.

4. Contact your vendor and get the motherboard replaced.

SOURCE: My computer turns on but nothing responds

Most likely your motherboard was DOA. Send it back for a replacement. Sounds like you've done all the troubleshooting double check the power supply connector...especially the P4 connector that I have occasionally forgotten to plug in...that will also cause the symptoms you describe.

SOURCE: jagged lines due to video driver/motherboard?!?!

If it works fine without a driver and only faults out when you apply the driver it would suggest that the driver you are using is incorrect. You may also be trying to start out with too high a resolution on your screen try lowering it before installing the driver.

Also ensure that you DO have the CORRECT driver

if yours has L75II8 on any labels underneath then go here to get the correct drivers

Also make sure you know which bios version you have as there were at least two Major revisions of this model and you may weel need to know to get the EXACT drivers

You might also want to update the bios for your revision if you can.

How to reformat pc hard drive?

Very simple, first take backup of all your Data on a Separate Hard Drive or CD, DVD, BluRay or Pen Drive etc. Afterwards, use your Operating System disk (that you're going to use after formatting), as you insert Operating System CD/DVD in your CD/DVD Drive, you'll get options out of which one would be suggesting you to format your Hard Disk, In Format Options, you'll get two sub options or even more, better and safe to choose default option (On which the cursor automatically sets before you choose, but if uncomfortable, call your Computer Service Center). As you hit that option, you'll find your Hard Drive getting formatted and after that, your computer will prompt you with Operating System Installation options.

And if you're about to format a Hard Drive, but not to setup an Operating System on it, even easier: After Backup of your data on that Hard Drive, just right click its icon and choose Format and you'll be able to do so after a few options.

Also, you can learn from Help and Support Section.

It keeps turning off on its own

I would do this: Start it in safe mode and perform a system restore back to the time it worked.
If this doesn't work, you'll have to boot from a system CD/DVD and do a Windows repair.
I think this is a software issue. But before you start reformatting your hard drive or something, open the computer up and disconnect everything but the CPU, memory, mouse, keyboard, and video. That will rule out the possibility of bad hardware.

My computer was reformatted. i can't play any audio/ video materials in my computer.

That is part of reformatting. It erases all of the data that was on your hard drive. you will need to install a new operating system and reacquire your materials.

The hard disks file system is corrupted.

If you can still access the PS3 menu, then reformat your hard drive by going to:

Settings > System Settings > Format Utility > Format Hard Disk

If you cannot, then you can try:
1) Remove the Hard drive, connect it to a PC and reformat it.
2) Download the latest PS3 operating system from the Playstation website and store it on a USB drive. Then insert the USB drive into the PS3 and start the PS3, and then install the operating system from the USB.

Audio glitches

When your CPU is staying at 100% run, that means you likely have gotten a virus or some serious spyware. Those can affect your audio and video playback, because some viiruses and spyware attach through your audio/video. try running your antivirys software; you can also try doing a system restore. if that does not work, you will probably have to reformat your hard drive and then do a fresh install of your operating system.
