Toshiba satellite L350 model no. PSLD8E-0ME024EN if you need to know the more technical stuff like RAM please ask :-) it uses windows vista Okay, so this is what happened: Last night, I decided to clean out a few things in my laptop because Toshiba Tempro told me that my hard drive had reached over 75% of its capacity. I did a disk cleanup, and a disk defragmenter, and deleted files (like old pictures and documents) that i did not need. The defragmenter took ages, it took about an hour and a half and then I had to go babysit my cousin, so I left my laptop on standby, so it could continue (or so I thought it would continue, but it might not of) my defragmenter was apparently scheduled every wednesday but I thought I should do a manual one as I have not defragmented my laptop, the whole time I had it. When I got back it was fairly late and I had to go to school today so I left my laptop on standby, as it was before. I took it off standby this morning, quickly checked facebook, the defragmenter was still running and had not finished so I cancelled it and turned off my laptop. I turned my laptop on about an hour ago, to find that my Windows Vista theme (the little circle as the start menu logo, with the windows logo in the circle, with the black taskbar things at the bottom of the screen and the top it was purple, as I had customised it) had turned into the grey windows classic, the really old one! I thought nothing of it until I tried to change it back in the themes bit in the control panel, and there was no avaliable themes apart from 'my modified theme', 'windows classic' and 'browse' I clicked browse but could not find anything. I then went to look on the internet for a solution, but my internet would not work. The wireless switch was on, my mum and dad's ipod touches were working fine with the internet, and the family computer had the internet fine (i'm on the family computer now.) Windows could not find a solution either. My Kaspersky Anti-Virus was turned off so I thought I'd better turn it on, and it said it was unable to turn on. I then tried to do system restore- I thought maybe I could go back to how it was before I defragged and everything last night- "System restore failed." when I only opened the program. I can't really reboot my laptop, as I have all my schoolwork, my photography, my coursework... and my external hard drive is not big enough to store my stuff while I reboot it. Can anyone help me? I tried phoning Toshiba but they are closed, and I really need to get my work done and everything...? :\ thank you in advance...
