Hi Lainey,
if you have a Windows 7 install disk then try booting off that and then when you get to the install screen click repair.
Another thing you could try is if you could manage to get into safe mode (try the F8+shift combination) then look for last good known config' and try setting the machine back to that.
As your getting bsod's I'll move your thread to the bsod section. If you do get access to the windows files then we can read the dump files created when a machine bsod's. These can found in a folder marked 'minidump'.
This thread can also help in attaining bsod details:
