No boot when CD is in drive. Problem with PSU??

Hi,
This is my first post here, and I must say hardware is not my specialty (yet). I've been having a recurring problem.

My computer has trouble booting. The first time this happened it wouldn't boot at all. I took it to a computer store and they said that there was a power surge and I needed a new motherboard.

Then when I got it home I noticed that I would have to press the power button several times before it would boot. IE: it would look like it was going to boot but then it would shut off. Back to the computer store. I got a replacement mobo on warranty.

Now, I am noticing the same problem. With an added bit of insight: When I try to boot, it will not if there is a cd in the cd drive. The only way I booted to post this is by powering up and quickly pressing eject. AND if I put the cd back in, once it revs up, the computer has a tendency of shutting off again.

Because of this, I suspect that it is the power supply. I'm guessing that somehow, the cdrom drawing voltage from the power supply (to rev up) is somehow overloading the system. (but what do i know :D)

Your theories and recommendations would be much appreciated.

Hardware:
  • mb: MSI K8N Neo4 platinum
  • cpu: AMD athlon64 3000+
  • psu: turbolink atx no: 400U-420PS

i would start by checking the boot order in the BIOS

BTW: i wouldn't think it was the PSU, but to varify what is make and model of PSU?

BTW: i'd also probably reset the CMOS / BIOS[ot]and hope, as always[/ot]

BTW: if you don't know how to reset the BIOS check here
 
I did try resetting the bios. Same problems.

What would the boot order have to do with it? Right now I have cdrom->HD->floppy. But the computer usually turns off within a couple seconds, much before it attempts to boot.

It's strange, once out of ten times I will be able to use a cd...but the other times. It just shuts off when one is put in.

I thought I gave the make and model of the psu... but maybe I gave the wrong info... I'm new to this :D. What info exactly do you need?

thanks.

sorry, my mistake, although i've never heard of the turbolink 400U-420PS (i assume it's cos i'm in UK) however tomshardware.com appears to think their ok here try another known working powerful enough PSU, for your system
