Booting problems

[Mr.Thunderbird]

Hello all!

I got a little problem.

I have this desktop machine, and my CD/DVD drive is a USB one. I can see it and the harddisks in BIOS options, but when I try to boot into system, or try to boot from an XP CD (which I has tested on another computer, and it worked well) and I have tried with another older XP cd.

Every time I try to boot from an XP CD it says that I should reboot my system and connect a right bootable device. When I try to boot from harddisk which already has XP installed on it, it says that some nddr thing is missing and that I shouls press CTRL+ALT+DEL to reboot. I thought it was my motherboard because sometimes my computer was turning off, so I bought a new one today, but the same thing (can't boot) happens with this one too. I've tried many different harddisk and still same thing (both SATA and IDE).

And btw, when I insert the motherboard driver CD, it boot without problems.

I hope you can help me on this one guys.

ANY help is appreciated.

Very strange, I first suspected on the MBO BIOS but since you told us that you bought a new MBO, that's a different story now..

Can you aquire another USB DVD-ROM device, or even try with internal one?

Thanks for the reply mate

I've borrowed an internal one already, so I'll try it soon.

Believe it or not, sometimes memory modules or dust on memory modules can cause these conditions..

Well it finally works!

Lol, offtopic, but look whats up with my explorer.exe, does it always use that much mem?

Not really, mine is now at 35MB

[Mr.Thunderbird]

Weird.

My computer always does something weird. It just can't resist.

It's not a problem that it uses 150MB anyways, with this new laptop at 4GB Ram, it can handle it
