Okay, Here's the problem.

All of a sudden my monitor hooked to my Desktop gets no signal, so I can't use my desktop ... why?

Here's what I've already done.

Using the same cable I've hooked the same monitor to my laptop ... no problem
Swapped Cables ... no luck
Swapped Monitors ... no luck
I double checked the second monitor using both sets of Cables ... it worked hooked to my laptop just fine


I took it to my brother-in-law and hooked desktop to 2 more monitors with 2 more sets of cables and no luck, but they worked with 2 of his pc's
We also installed a 16mb video card, the cables did not work plugged into that card, but when we left that card in and plugged the cables into their
normal (previous) slot on the desktop, it started to work and worked until the next morning ... that same trick doesn't work anymore.

At that point, since the video card is 'onboard' the motherboard, I ordered a new one online (exact same model) and installed it and it's the same
thing ... can't use the desktop/monitor

Anyone have any other ideas? Without the ability to see what is on my desktop etc... how do I proceed?

Since posting the original post, I have added my hard drive to my wife's PC as a slave drive and was able to SEE my hard drive ...

I saved all the important stuff on my hard drive to the desktop on my wife's pc ... then I unhooked her hard drives and hooked in my own to see if I could boot up on hers and while it did not finish the boot, it did get to the screen that asked me if I wanted to Repair the drive and I chose to do that ... however, I got the following message when I tried:

Startup Repair
Startup Repair cannot repair this computer automatically

Problem Signature:
Problem Event Name: Startup Repair offline
Signature 01: 6.1.7600.16385
Signature 02: 6.1.7600.16385
Signature 03: unknown
Signature 04: 21200941
Signature 05: AutoFailover
Signature 06: 3
Signature 07: BadDriver
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033

I have since reformatted my old drive and will attempt to re-install Win7 on it and see if I can get it going again.

Hello moondog830

If you still require assistance with this can you provide some information about your computer, this includes is it a custom build or brand name such as Dell or HP, if it is provide the model name or series number (not serial) if a custom build post the brand and model name or number for the MB, add on video card if one is used and the PSU (power supply unit) providing these details will enable us to better assist you.

not sure what help you might be able to give at this point ...

My PC is a Gateway Model DX4831-01e
SNID is 95101938127

I have a bootable win7 disk, however, when I put it in and attempt to re-install Win7 x64 ... I get an error and am now allowed to continue, but at the point the PC can communicate with the monitor. So I guess, now, my issue has changed.

Lets take a look and confirm a couple of things first :thumbsup:

Is the computer at the link the same model as yours http://support.gatew.../DX4831nv.shtml

I have a bootable win7 disk,

From where was the disk obtained.

when I put it in and attempt to re-install Win7 x64 .

Has the boot sequence been changed in the BIOS so that DVD drive is the first boot device and the HDD is the second boot device.

I get an error and am now allowed to continue,

What error do you get (exact message if you can please) do you mean that you are "not allowed to continue"

but at the point the PC can communicate with the monitor. So I guess, now, my issue has changed.

This may suggest a driver issue which we will come back to in due course.

From your OP;

since the video card is 'onboard' the motherboard, I ordered a new one online (exact same model) and installed it and it's the same thing ... can't use the desktop/monitor

What you describe suggests that you have replaced an add on video card and not "onboard" as an onboard video chip is integrated and cannot be replaced without the aid of specialist assistance that can safely use a soldering iron around a motherboard (MB).

Yes

I have a bootable win7 disk,

From where was the disk obtained.

My brother-in-law purchased it with a number of activations

when I put it in and attempt to re-install Win7 x64 .

Has the boot sequence been changed in the BIOS so that DVD drive is the first boot device and the HDD is the second boot device.

Yes ... I made sure of it

I get an error and am now allowed to continue,

What error do you get (exact message if you can please) do you mean that you are "not allowed to continue"

Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information. (I have no idea where these would be located)

but at the point the PC can communicate with the monitor. So I guess, now, my issue has changed.

This may suggest a driver issue which we will come back to in due course.

Ok

From your OP;

What I meant by 'onboard' was that the machine came with it and the motherboard has all the 'connections' for all the peripherals ... I have not added anything at all to this machine.

As I said though, my issue isn't the video at the moment because I have no operating system on the machine now.

Thanks for the update moondog830 :thumbsup:

I was trying to establish if the installation disk that you have is a genuine Microsoft product or one that you have created such as one of the following Methods

Is the disk that you have shown in the attachment below;

Once that we know the type of disk that you have we will have a better idea of what we should check first.

it does not look like any of those ... what he gave me to use was a copy of his ... he didn't want me to 'disappear' with his original ... he said he used it and it worked fine. I am taking my machine to him on thursday and he is going to also see if he can figure it out, but if I don't have to make the trip there on thursday that is a bonus ...

however, I understand also, that since I can't prove to you this is a legal copy (all you have is my word) you may not be able to continue helping me either.

You have not given us any reason to believe that the disk that you have is not a legitimate one, what I was looking for was any reason why the OS would not install from the disk to the HDD, this can happen with downloaded ISOs that have been burned at too faster speed, corrupt files, a damaged disk and Windows 7 being burned to a CD disk instead of the required DVD type disk.

As long as the copy of the disk that you have is from the same version that you have 64-bit home premium for example and that you use your own legitimate 25 digit product key to register the OS when it installs you are perfectly ok, do you happen to know if the disk that has been copied for you was copied from a genuine Microsoft disk or an ISO etc!

Moving on see if you can access the HDD using Puppy Linux and let us know how you get on, the next step would be to try the manufacturers diagnostic tool that is appropriate to your brand of HDD, see Here

===================
***Required Hardware***
CD Burner (CDRW) Drive,
Blank CD,
Extra Storage Device (USB Flash Drive, External Hard Drive)

===================

1. Save these files to your Desktop/Burn Your Live CD:
  • Download Latest Puppy Linux ISO (i.e.: lupu-528.iso)
    Download BurnCDCC ISO Burning Software

    There are instructions on how to boot from flash drive with puppy here; http://www.pendrivel...e-from-windows/

  • Open BurnCDCC with Windows Explorer
  • Extract All files to a location you can remember
  • Double Click Posted Image BurnCDCC
  • Click Browse Posted Image and navigate to the Puppy Linux ISO file you just downloaded
  • Open/Double Click that file
    IMPORTANT: Adjust the speed bar to CD: 4x DVD: 1x
  • Click Start Posted Image
  • Your CD Burner Tray will open automatically
  • Insert a blank CD and close the tray
  • Click OK
Puppy Linux Live CD will now be created
2. Set your boot priority in the BIOS to CD-ROM first, Hard Drive Second
  • Start the computer/press the power button
  • Immediately start tapping the appropriate key to enter the BIOS, aka "Setup"
    (Usually shown during the "Dell" screen, or "Gateway" Screen)
  • Once in the BIOS, under Advanced BIOS Options change boot priority to:
    CD-ROM 1st, Hard Drive 2nd
  • Open your ROM drive and insert the disk
  • Press F10 to save and exit
  • Agree with "Y" to continue
  • Your computer will restart and boot from the Puppy Linux Live CD

    Posted Image

3. Recover Your Data
  • Once Puppy Linux has loaded, it is actually running in your computer's Memory (RAM). You will see a fully functioning Graphical User Interface similar to what you normally call "your computer". Internet access may or may not be available depending on your machine, so it is recommended you print these instructions before beginning. Also, double clicking is not needed in Puppy. To expand, or open folders/icons, just click once. Puppy is very light on resources, so you will quickly notice it is much speedier than you are used to. This is normal. Ready? Let's get started.

    3a. Mount Drives
  • Click the Mount Icon located at the top left of your desktop. Posted Image
  • A Window will open. By default, the "drive" tab will be forward/highlighted. Click on Mount for your hard drive.
  • Assuming you only have one hard drive and/or partition, there may be only one selection to mount.
  • USB Flash Drives usually automatically mount upon boot, but click the "usbdrv" tab and make sure it is mounted.
  • If using an external hard drive for the data recovery, do this under the "drive" tab. Mount it now.
3b. Transfer Files.
  • At the bottom left of your desktop a list of all hard drives/partitions, USB Drives, and Optical Drives are listed with a familiar looking hard drive icon.
  • Open your old hard drive i.e. sda1
  • Next, open your USB Flash Drive or External Drive. i.e. sdc or sdb1
  • If you open the wrong drive, simply X out at the top right corner of the window that opens. (Just like in Windows)
  • From your old hard drive, drag and drop whatever files/folders you wish to transfer to your USB Drive's Window.
For The Novice: The common path to your pictures, music, video, and documents folders is: Documents and Settings >> All Users (or each idividual name of each user. CHECK All Names!) >> Documents >> You will now see My Music, My Pictures, and My Videos.

Remember to only click once! No double clicking! Once you drag and drop your first folder, you will notice a small menu will appear giving you the option to move or copy. Choose COPY each time you drag and drop.

YOU ARE DONE!!! Simply click Menu >> Mouse Over Shutdown >> Reboot/Turn Off Computer. Be sure to plug your USB Drive into another working windows machine to verify all data is there and transferred without corruption. Congratulations!
