I have a pavilion xt9633 with Xp for an OS. I installed a new 128 MB NVIDIA 5200 FX Videocard. It ran well for several bootups and shutdowns, but I had just set up an IPX protocol so me and my friend could play DII together and then I did one other thing, can't remember what it was, but then I got a blue screen that said Unmountable Boot Volume. I tried using a dell xp recovery cd, that didn't work (not sure if it mattered that I had an HP), then i dl the six disk recovery from the net, that didn't work, then I tried using the built in recovery when u hit f10 when the HP blue bootup screen comes on, and that looked like it was working but then it said Page in nonpage area or something like that on a blue screen. I've talked with HP and every method they've told me to try has failed. Ne help please.?? Thankyou
