Fails after start up--"system unstable"

I have a bad problem with my PC--after it boots up to the normal start
screen, within several seconds I get a blue screen message from my Gateway
Goback program saying my system has become unstable and must be rebooted to
avoid disk corruption. Occasionally, it will show a fatal exception message
after the Goback message. The system does not do this when started in safe
mode. I have run complete scan disks (data and surface area) in safe mode
with no problem found, also system file checker and registry checker, again
no problerm found. I have also run my antivirus using the rescue disks in ms
dos mode with no infections found. Also, my Gateway comp came with a "GW
Scan" disk which checks the physical condition of the hard drive--no problem
found! I have no idea what to do- is it a hardware problem? Virus?
Software/system issue? Someone help!!!!

For all I know it could be the Gateway Goback application itself. Start in
safe mode, press start, run, and enter in msconfig, disable the Goback
application, and see if it will then boot into regular mode AND will
function properly while in there. If you don't want to use msconfig then
here's a handy application to use instead:

Remember, don't delete the entry, just disable it for now.
