Hello, I've got a problem =)

Recently, I boughta PC (AMD 2400), which has all the normal features like onboard lan, video, etc.  I wanted to do a little bit of gaming, so I installed an old GEForce 440 MX agp card, and it worked fine.  I upgraded to a new sound card so I didn't have to use the onboard audio anymore, and I told my friend who was downstairs to plug the necessary cords back in, and that would be it.  However, when I came back downstairs, he had plugged the monitor into the onboard video, which would obviously result with a blank screen.  I shut down the machine, plugged it into the agp, started it back up, and it seemed to be going fine.  But the machine would halt on the loading icon screen for XP (XP Pro SP3).  I tried to start up using Safe Mode, but each time, the WinXP icon screen would rest there, and eventually give me a blue screen of death, before going back to the startup (BIOS, etc).  The bsod states problems with hardware, and says the obvious header of BAD_POOL_CALLER, and also states near the bottom the following:

STOP: 0X000000C2 (0X00000043, 0XC2DDD000, OX00000000, 0X00000000).

So I'm wondering what the hell to do here.  I loaded up using Knoppix, and I found that the data on the HDD was still there.  I also tried to set the HDD to primary slave, and run it under my father's machine (XP Pro), and it picked up fine, however, I couldn't copy the necessary data from one drive to the other, because this modified slave uses User Accounts for Xp, which is where all the necessary data is stored.

So to make a long story short, the hdd is currently primary master, but won't get past the XP icon loading screen, and after about 5 seconds, goes right back to the start again.  Any help someone could provide would be greatly greatly appreciated.

Your friend caused a video driver error, and now it doesn't know what video driver to use.  If you do a repair install, you will be able to get back to a working system, but you will have to apply updates.

Thank you for the assistance...I tried the methods that were in the link you posted, but to no avail.  I'm really baffled here, because I've tried everything I know how to get this corrected.  I'm at the point now where the data on the drive doesn't matter, I just want to get it formatted and an os put back on there.

Basically, this drive was (for some reason) was an 80gb hdd, seperated into 4 and 76gb partitions.  What ended up happening was I attempted to combine the partitions using Partition Magic, but it was unable to do so without formatting the drive, so I figured, what the hell, I'll leave it the way it is.  But now, since this video driver mixup, I wanted to get it back up to speed, but I can't do anything.  Each time I try to boot using an xp cd, both XP + SP2 and SP3 cd's, it doesn't give me the option of the repair using "R", it will copy the files like it always does, but before it hits the gui section, it will revert back to the bsod and I'm back to square one.  I've tried to fix this, but somehow, now, the 4gb partition is the only one reading as NTFS, and the other 76 doesn't even register.  Ideas?  I've tried using fdisk...the 4gb ntfs registers fine, but the rest of the space is like, I don't even remember, but it's less than 10gb, and it doesn't have a file system associated with it, so there's nothing I can do with it.  I added this remaining space as a primary dos or an extended drive (don't remember), but that still doesn't associate it with ntfs.  I'm considering that perhaps this hdd is now full of bad sectors or something, but when I set it to primary slave on my father's machine, I can still see the data within explorer.  I'm really at a loss here...?

Thx for the assistance, but it didn't get me anywhere.  I'm drove up the wall with this, after working on it for 3 days straight, so the hell with it...I've formatted, fdisk'ed, partitioned, set it to other people's machines, everything I can think of - I'll just go back to my other machine and throw this one out the window =)  Enjoy the 250pts.
