Ok so, my computer problems have been compounding one on top of each other. So I'll start with the first problem:
I had my laptop connected to my tv w/ an hdmi chord and I'm pretty sure it overheated so it crashed, I tried to turn it on a little bit later once I thought it had cooled down, it didn't, so I just switched to something else. The next day I turn on my comp. and it seems to load longer than usual, once my desktop loaded up, absolutely everything is incredibly slow, I was having problems w/ the taskbar and it was the first to freeze up, I couldn't even soft shutdown through the Start button and so I had to hard shut it down. Turn the comp. back on, problem persists, slow startup and restart, slow desktop, constant freezing of everything. So I kept trying to fix it doing different ways, chkdsk, sfc /scannow, it all took way too long or just froze up, or like sfc wouldn't start on the restart, but everything was taking absolutely forever. I tried system restore but got some registry error message. After several restarts I also noticed my wifi would not recognize my wireless network, it just shows it as a disconnected lan.
Then after several days of attempted fixing and hard shutdowns, crashes, I think I finally go to the point where it just wouldn't even boot, luckily I was able to get my hands on a windows cd and boot it back up into safe mode I think, but comp. crashed enough so I wasn't and still not able to boot it back up again. Using the cd I got into the advanced startup options and tried startup repair, I read doing it three times is best, I did, found nothing. I've been doing chkdsk /r C: for the last couple of days 3 times now. Tried running sfc /scannow, but keep getting error message, "There is a system repair pending, please reboot", I did reboot, still same error message. Went through google for help, tried to delete, move, rename the pending.xml file, always says file not found. The one time I was able to get sfc to work was w/ sfc /scannow /windirboot="C:" . . . something like that, don't remember exactly, then got the error message, "found corrupt registry errors, not able to fix, error message is in cbs.log", but obviously I can't read cbs.log because I can't even get into safe mode. I've attempted scanreg /autorun, and /fix, neither worked, don't quite remember the error message. I've even attempted bootrec.exe /FixMBR, found no errors. I did finally have one breakthrough, I wanted to see if the chkdsk worked and fixed my boot, it did! Was able to boot into regular windows, all seemed fine except my wifi and then restarted into safe mode, restarted again but then proceeded to not even boot again, had to even change the boot order in the bios to cd/dvd to be able to boot again.
So yea, I think I'm at the end of my IT knowledge and I think the only option left is to set it back to factory settings, I was able when I was in safe mode to backup a good amount of stuff, but not everything, so don't really think that's an option so when I get a new comp., I'll just connect the HDD from this laptop to my new comp. and backup what's left. So is there anything else I can do? I'm going to try to run sfc /scannow again, boot again into safe mode and see if I can get more stuff off, and also see if I can run the system restore now.
Laptop is a Toshiba Satellite A665.
Thanks for the help and for reading.
