Hi, My computer freeze at the windows XP boot logo. I then press the power button and it restart to get me to a screen where I have the option of save mode, last good boot, etc. plus the normal boot option. I hit enter for the normal boot option and windows start up fine. This cycle repeat every time I turn off the computer and restart it. Any know why this is happening? thanks for any help. Extra info: computer is an eMachine T3101 sempron 3100+ which I installed 2 new 512 MB sticks of RAM and a new hard drive. I also plugged in a USB keyboard. Everything appear to work fine once windows starts.
