I managed to fix it so it gets past the logging off screen, but now it won't shut down. It spends hours on the 'Shutting Down' screen, and I can't fix it. I tried to troubleshoot it, do a clean boot, but it hasn't fixed it, and I don't know what's causing it.
In addition, the disc drive won't load up anything. DVDs, CDs, games, nothing. The bar loads part of the way and then stops, again, for hours. I don't know if this is linked in any way.
I haven't installed any programs recently, and this has come on rather suddenly. Just a couple of days ago it was just fine, and I don't think I have any viruses, unless they're incredibly sneaky.
Any help would be greatly appreciated
