Here's a quick overview of what happened today. Earlier today when I switched off my laptop, it installed updates before shutting down, and I let it do so, I didn't try to switch it off or interrupt the process. About an hour later on the bus home, I switched on the laptop, and it started configuring the updates. It got to about 15%, then the battery cut out (I hadn't noticed it was low). I left it, and then plugged it in once I got home and tried to boot it, but nothing. I got the VAIO screen, the 'starting windows' screen, and then it would just restart and go to Startup Repair. I've literally tried every option in startup repair, but the repair can't fix the problem, system restore has failed three times trying three different restore points, and a memory check has come up with nothing. I've tried booting in safe mode, but it just restarts again. My laptop is a Sony Vaio VPCCW1S1E, running Windows 7, and I honestly don't know what the updates were, as I can't check. I also don't have a Windows DVD, I never got one with my laptop, and the warranty has been up for a year now. Any help would be greatly appreciated. I really can't afford to completely reinstall the system, as I currently have no way to access any of my files on there which I need for college and such. If you need any more details to help, let me know, thank you!
