6.2 install problems

[Morse <morse nospin org>]

I have just downloaded and burned the 6.2 image file. I then boot off the 
CD and started a New install on a PC with RH 6.1. I choose to delete and 
format the existing Linux Native partition and use the existing swap and 
install everything. This is a 3 GIG partition. I go through the 
install...it formats the partition starts installing packets and when it 
gets to around 50 it just reboots. No error message, no warning 
nothing...just reboots. I gone this twice now. Anybody know why ?
thanks
