booting problem

[kehar]

hi
I am using IBM PC and ever since I installed second DVD RW my computer has started
giving following problem.

sometime when I switch on a message appears in black background giving me the option
to start in either Safe mode, normal mode etc etc
when I opt for normal mode then after logging as a administrative user and while using any application the computer automatically gets shut down and again restarts with the same option as stated above.

I am using two hard drive and two DVD R/RW and they are connected as
for Primary port - one hard drive in which XP is loaded as primary master
and one DVD R set as primary slave
for secondary port- another hard drive as secondary master
and DVD RW as secondary slave
Will any one help me

Reinstall or repair your operating system. Check if this helps.

try hooking devices this way ,both hdd on primary one master one slave ,and the 2 dvdrw on the secondary one master one slave .it is better to transfer file to the dvdrom from the hdd when they are on separate channels anyway
