Okay so here's my issue. I took my pc apart a few days ago , to check how much space I had for extra hard drives etc . And now it will not work. It's as simple as that tbh, I removed some wires but everything is back exactly where it was originally. When I started my computer it would say Windows is starting, but then go to a black screen with just a mouse. Then after messing around in the bios or whatever I somehow I ended up on the screen where you can "Launch startup (recommended) / Start Windows normally" the latter of which flashed up a blue screen then quickly reboots back to the same screen. The other option I went through trying to do repairs but after 5+ hours I have to admit it's not done a damn thing. I have no system restore/backups that I can use - I have 750gb worth of data I do not want to lose. My last option was to download and install Windows 7 I so onto a DVD, change it to boot off CD/dvd and try to do some diagnostic repairs but I am stuck at the starting Windows logo yet again. Has anyone got any ideas on what else I can do? I only took the thing apart and put it back together I really can't see why it just won't start
