Windows 7 will not start.

[mikekerstetter]

I have an eMachine running an oem 64 bit version of Windows 7 home premium that will not boot, even in safe mode. It freezes just prior to loading the windows logo. I can get it to the startup repair mode and the screen with the safe mode option, but it goes blank when I click on safe mode. Startup Repair will run, after a 45 minute period of 'loading files', but says it can't fix the problem. It then asks me if I want to use system restore. I've tried that twice, and it has booted windows afterwards, but shortly after quits working. I can't seem to get it to restore a third time.

My problems started after several automatic updates were applied yesterday morning (Thunderbird, java and several windows updates). After the second system restore I tried changing the windows updates from automatic to prompt me to install. I'm not sure what the problem is and need some advice to correct the problem. I consider myself a novice. I don't have the installation cd and I've not made a boot disc for it. Can anyone help me?

(I have no idea what a dump file is or if I can even get one on the computer that isn't working)
