Recently every time I connect my SII to my computer, the BSOD pops up with the error message "Bad_Pool_Header" I then uninstalled KIES and everything is fine again, but as soon as I reinstall KIES, the problem comes back again. The same problem occurred when I tried plugging in my phone to my other computer, and uninstalling KIES fixed it as well. Both of my computers are running Windows XP, I'm not sure if that's a coincidence or what. I tried uninstalling and reinstalling all my usb port drivers but that didn't fix it. I appreciate if anyone can give me some suggestions on how to solve this problem because it's been very annoying to me.
