Hello here you can download a manual:

By entering the right mainboard number.

Try to set the bios to factory settings.Load default settings.
And set the boot order: first boot device:dvd, second, the harddrive.
If you are using a IDE drive make sure its set as master.
A sata drive does not have that function.
Make sure the windows disk is clean and without scratces.

Here is a youtube video that shows you how:

Good luck

Bad stick of memory? If you have multiple sticks, try removing one, then the other, and see how far you get with installation.

SOURCE: biostar gf7100 mp - wont boot with ext usb drive attached

Hi, What you have to do is shut down the machine, pull the CMOS battery(CR2032) out and out and put your jumper on pins 1-2 from 2-3. Wait 30 seconds and put the battery back in. After installing the battery, put your jumper back to pins 2-3 from 1-2. This should work.

SOURCE: Problem with Biostar P4M800-M7A Motherboard

I had exactly the same problem.... waste hours on it. I solved it by clearing the CMOS. Pins 1 and 2 on JCMOS1 are closed in normal operation mode. Move the jumper to pins 2 and 3. I then pressed the power button a few times (the motherboard will not respond to the power button at all when it is configured to reset the CMOS), but I don't think pressing the power button is neccessary. After about 30 seconds, put the jumper back on pins 1 and 2, and power up. When I did this the motherboard responded finally. Hope it helps! :D

Try Windows7 instead of XP, since XP doesn't support SATA drivers to read your HDD

PC shut off during update install now I get bsod 0x000000ED

I think you may know the answer already. It's a matter of sacrificing one of drives, if you can't purchase another drive right now.

Live boot with Ubuntu and copy just the data needed onto the other drive. You now have all the data on one drive allowing to wipe and reinstall XP on the other.

You may still have unresolved hardware problems, if the newly wiped drive blue screens again.

Biostar TA790GXE 125M keeps shuting down when I boot windows, on SATA and IDE hard drives

Run the Check Disk Utility.

To run the check disk utility you will need a repair disc or a operating system disc. Put the disc in the cd drive and boot from it. You want to get to the Dos Command Prompt (Black screen with white letters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair when the options appear.

In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.

Laptop won'y start up has non-system disk or disk error

The error PXE-E61: Media test failure usually means the hard diskhas failed or the hard disk needs re-seating or the disk controller is faulty.First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty.Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

My hp pavilion dv7-4285dx has lost everything, os and all. How can I get it to read the recovery disc I ordered from HP?

What makes you think you've lost everything? Unless you specifically instructed your computer to Format the hard drive, I would doubt very seriously that you have lost everything. Everything might still be there, but a virus has hidden it to make you think you've lost everything. Oh, one more way to lose everything is to interrupt a System Recovery before it completes, or interrupt an Fresh Install of Windows before it completes.

A lot of times the System will think you've lost everything because somehow a setting the bios was changed either by you or some virus and it has set the hard drive where it is not detectable. Turn your computer off then watch the screen to see which key you have to hit to get into the BIOS or SETUP or System Setup.

Once you are in the BIOS scroll through it looking for AHCI that will be associated with disk drives or disk controllers. If it is Enabled, Disable it and Boot your machine. If it is Disabled, Enable it and Boot your machine. In other words just change the settings for AHCI.

Do that and report back.

Hello. Completely out of the blue, when I turned my laptop on it immediately went to a black screen that said "A disk read error occurred press Ctrl+Alt+Del to restart." But when I do it takes me...

When your system boots it looks for a startup file which is located on your hard drive to load your operating system. If your system doesn't find your hard drive it would post a disk read error message.
To be sure your HDD is detected by your system, you can go to your BIOS setting by pressing DEL or F1 or F2 or F12 it depends on your BIOS maker then try to see on your BIOS setting configuration if your HDD drive is detected or not.

Sometimes and always happens that we forget a media disc on our optical drive and since the default first boot device is the optical drive the system looks for a startup file on it and post a disk read error. So check if you leave any disc on your optical drive and remove it.

It is very safe to configure your BIOS setting to set the HDD as the first boot device in case we leave something on our optical drive most of the time.

Hope this helps.

I have no sound I install the driver but there is no sound.

Try to install the driver in the case where the card effected gently.So keep it up on that case where it can continue to work.
