I have a 6 year old gateway desktop, it has windows vista. The computer will not stay turned on when i boot up (won't boot up), i also use it as my wireless master and do not have any issues with my wireless networking. What could be the problem?

Time for a new computer

Or-- install whatever parts are needed in the gateway
& load a fresh new version of the Windows Operating System
of your choice Win 7,8 or 10

Forget the warranty & just pay to have it fixed

It should not effect the booting of the computer as it boots from drive C. You can delete it using file explorer.

The wireless feature on a Gateway computer allows you to connect to a network without the hassle of cables. This allows you to browse the Internet conveniently wherever you are. Gateway computers rely on Windows operating systems, which come with a built-in feature to manage your wireless connection. This feature makes turning off your wireless connection an easy process if, for a moment, you prefer to connect to the Internet using a wired connection.

Click the Windows "Start" menu and click the "Control Panel." Click Network and Internet Connections > Network Connection, if you are using a Windows XP Gateway computer. You should see your wireless connection. For Windows Vista and 7 Gateway computers, click "Network and Sharing Center" from the Control Panel and click "Manage Wireless Connections." You should see your wireless connection. Right-click your wireless connection and click "Disable" to turn it off. Close "Network Connections" when you are done.

You need to access the BIOS - press F1 or F2 (depending on the version)during the start of the desktop - and in there you must modify the boot order: put the cd first then the had disk second. Save the change, reboot, insert the Vista disk and reboot once more - the disk will be loaded.

with the computer off, turn it on, and right before the windows screen pops up hit F8. this will bring up a boot menu, select "Disable Driver Signature Enforcement"

This should allow the driver to work. The only problem is that you will have to select this at every boot up.

Network cards are in expensive these day, i would get a newer one that will have an updated driver.

0x00000070 error means that Windows start up failed in an early stage.
If you are unable successfully boot into Windows because of the this error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:

1. Reboot the computer.
2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
3. When successful, you should see a back screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.
4. If this does not work you may have already reformatted the original disk partition. If that is the case you will have to re-install windows from scratch.

Without seeing the machine, I'm thinking you have a motherboard problem. But try these troubleshooting steps before throwing in the towell:
Open the case and disconnect the CD cable. Now try it. If it still doesn't work, disconnect the hard drive and try it.
Let me know what happens. I've seen CDs mess up a system like this. I many times will swap out the power supply, but I'm thinking with the lights flashing, its a more serious problem.

Sounds like the computer is coming from sleep, standby or hibernation mode. Go to the power settings in the control panel, and disable all of these options. Disable your screen saver as well. Leave the machine on for a day and see if it happens again after this. Post your findings, please...

I would say there a minor corruption in your hard drive. How old is this computer?? May time to reformat it.
