if there is something about a startup repair and you feel that there was some progress i think you should try restoring windows first before you ship the notebook (this will surely be your last resort if you can't get it fixed) to them coz i think it's really a pain in the a** to be away from ones beloved "brand new" notebook for a very long time. Like what I have said before, when i got mine there were some issues in my installed vista so what i did is restore my vista through gateway restore, which is in the secondary partition. If still this does not help then most likely you have a hardware problem and you will really need to send back your notebook to gateway if you can't pinpoint the problem. If you have some friends who have notebook computers and their ram is compatible with yours, you should borrow one and test it in your laptop first and see if this is what causing the problem so you could just address this to gateway and maybe you wouldn't need to send the whole thing. When i try troubleshooting my desktop what i do is disable some of the hardware like the LAN, wifi, dvdrom, modems, audio card, etc on the desktop manager and open it one by one to see if one of it is causing the problem. You should try that too. This unfortunately would be very time consuming coz you are going to have to test it for very long periods of time to see if your notebook will not hang or restart. If you do pinpoint the problem though you still need to send your notebook back to gateway, but i guess it wouldn't take very long because they will already know what to fix. Goodluck.
