Hardware problem

but if I disconnected CD rom it wouldn't boot up but it woudl get to post.
bazaar stuff if you ask me thanks so much everyone Chris you rock. (everyone else too but he responded first.
)

Kn1ght. You can have a look at your bootup sequence. It may be that the sequence looks to the CD Rom for the Operating System. You can however, change the boot up sequence. The "normal" sequence is "A" Drive, CD Rom, Hard Drive. But of course, you can change that to whatever you want. Hope this helps!!

Cheers

I agreed with bishop i've encountered when DVD rom culprit i thought the problem is in the power supply when i replaced new power supply it smell burned and i found out the reason why power supply smell burned is the DVD rom when i unplug the all DVD rom the problem won't happen again.
