Clarifying problem Went to turn the computer on one day (no problems prior to that) and it would continuously reboot t. Decided to boot from Windows XP CD, I reformatted the HD and reinstalled windows. Did check disk and everything was working great. So I started doing the windows updates. After I go them almost done (there were about 100 of them) it rebooted and keeps rebooting. Just like when I started!

SYSTEM RESTORE Windows XP

Switch ON the PC, boot the PC in 'Safe Mode' by continuously tapping F8 button after you switch On until you get the Safe Mode Option.

Let windows boot in Safe Mode and log in to windows.

Go to 'Start'--->Programs--->Accessories--->System Tools--->Click 'System Restore'

A 'System Restore' window will appear.

Here you will have to check "Restore computer to an earlier time' and click Next

Now you will find one Month Calendar window with Dates below, go to the previous month by clicking the '

Note: It is better if you could remember from which date you are facing the issue, try to select a date prior to that date.

The detail of that particular date should show "System Checkpoint" and time on the right hand side box. Select that date.

Now, Click on Next and System Restore will start and windows will take a reboot.

After reboot your problem should be resolved.

6. Reinstall any software programs or hardware you removed one at a time. Reboot the computer after each installation. Make careful notes of any error messages or boot problems you experience.

All the Best

are you pressing any key to boot from the cd when you get that message??

after windows finishes copying all the installation files during the first stage (dos mode) of the os installation you get a reboot, after the reboot, you should get that message that says press any key to boot from the cd, DON'T PRESS ANY KEY (or you will start again), leave it cd in.. just don't press any key... hopefully the installation process will continue on it's own onto the next stage (graphical mode).

if the computer just goes back to the dos mode without you pressing anything the problem may actually be a real problem and it may require further troubleshooting..

see how that goes with the first suggestion and post back if needed.

good luck

You probably added the wrong Ram memory. Some if those 512 memory, are not suitable for windows XP and UP.Try removing the 512 Ram module and see what happens.
Good luck.

Write zeros to the HDD using the HDD manufacturer's software, and then partition it, format it, and install your OS

its been a bad install of the drivers, boot into safe mode and uninstall the display drivers, reboot the machine and it should reinstall the drivers itself

I had the exact same problem!! Drove me crazy for days. Couldn't find any answers online, contacted Gateway tech support and they told me my warranty was expired but they'd be happy to discuss my issue for $2 per minute. Gateway can **** it!!

At first I thought the problem might be a malfunctioning NVIDIA card, a problem with my DVI cable, or the monitor itself. But, after turning off the computer, unplugging the DVI cable, replugging the DVI cable and restarting the computer, I noticed I could get the firmware flash screen to show, including the BIOS menu boot and the Gateway system reinstall screen to show. As soon as the Windows flash logo would display, however, the monitor would drop out and display the dreaded "No Signal" error.
This indicated the problem was a software one and not hardware! The cable, monitor and video card were all working fine. Then I remembered that Windows installed its automatic update a few days prior. In fact...

THE PROBLEM TURNED OUT TO BE A WINDOWS UPDATE INSTALLED A FEW DAYS PRIOR.

After succesfully booting into safe mode (F8 during the flash/bootup screens), I went to Add or Remove programs in the control panel, clicked on the "Show Updates" box on the top, and uninstalled the Windows update from a few days prior to the occurance of the error. After a reboot the problem was solved.

I hope this will help anybody else struggling with this error!

If Windows is continuously loading up to 800x600 then your drivers are not being installed. Are you using the the 169.21 Nvdia Forceware package? What OS?

have you tried to uninstall the vedio driver and reinstall it then let me know.go to my computer icon right click it > go to properties >hardware tab > device manager and check if there is any yellow mark showing.kindly do this in starting your computer in safe mode.
