I have a serious problem that I hope has a some what easy fix to it. Im running Win Xp. I press the button to start up the computer and it begins to go through the memory testing and then from there within seconds goes to another screen that gives me the option of safe mode, safe mode with prompt, start windows at the last know best config, start windows normally etc. No matter what I choose the computer begins to reboot and and in less then a minute im back to the same screen.... this continues if i dont shut off the computer. I have tried to reinstall win xp and managed to get it to go throught the initial process then crashes and reboots itself. I have tried to use Knoppix 4.0 straight off teh cd-rom but same result start to initialize but then reboots. I am out of ideas and solutions to this problem. I have other computers available to myself if making this hardrive a secondary in order to repair it. Please help!
