Okay, I'm just going to post this conversation of me and Conner, it's the fastest way and I really need help.  
Sky says: 
so when you start up the comp, right? it goes to the black screen where it shows sytem information etc 
Sky says: 
right after that 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Yea 
Sky says: 
I get a black screen with a _ blinking on it 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Ah 
Sky says: 
and usually I can press F76 and F7 fast and bring it up 
Sky says: 
but now it's not 
Sky says: 
it's always said 
Sky says: 
"Insert boot disk" or something 
Sky says: 
in a longer form 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Ah... 
Sky says: 
and I would guess that's my window's install disk 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Well, I don't know the solution, but I think it wants you to reinstall... 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
*GULP* 
Sky says: 
would that delete everything 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Well, yea really... 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Tried pressing any keys? 
Sky says: 
yeah 
Sky says: 
same message 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Aww 
Sky says: 
see, what I did 
Sky says: 
I put in my gfx card 
Sky says: 
didn't pull up 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Ah? 
Sky says: 
put the disk in 
Sky says: 
(probably not a good idea, I did it once and it actually worked) 
Sky says: 
it asked me if I wanted to do something 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
oh 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
ROFL 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
sorry 
Sky says: 
and I said no, in fear of deletion of somethign.. 
Sky says: 
and I quit out of that 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Can you remember what it said? 
Sky says: 
and after that it just shat out on me 
Sky says: 
no ): 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
Oh 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
*Sigh* 
Sky says: 
my p2 with 64mb of ram runs better than this pos. 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
xD 
..>..Connor..<..Loves..>..Rachel..<. - A fucking lot! says: 
So has this started happening since you put the gfx card in? 
Sky says: 
yeah 
Sky says: 
basically 
The disk being windows installation disk, which probably wasn't the best idea. Is there a way to enter safe mode etc?
