hp netbook BSOD. sptd.sys?

I assume the following is a hardware issue given the steps I have tried?
I have an old hp netbook which I use solely for diagnostics as it has pcmcia with R232 adapter. It stopped booting for no reason. Hadn't been on internet etc. Shut down normal and wont restart. It just stays on a black screen. I hit F8 and tried various safe modes and start up repairs with no success. On safe mode start it goes through the loading drivers etc then comes up hit any key to load sptd.sys, everytime it crashes when you hit a key. No option to bypass loading, tried everything. I had the old hard drive from the netbook as I had swapped it several months ago. Stuck the old hard drive in which was 100% operational on removal, I know this as I plugged it in a desk top and cloned to newer hard drive which has worked for months. This old hard drive behaves exactly the same so I suspect its not a file fault but maybe an internal component failed. Anyone hve any clues what piece of hardware could fail and be somehow connected to sptd.sys ?
Thanks

 

What CD/DVD burning software are you using? Daemon Tools and Alcohol 120% use the spdt.sys like Windows uses ASPI — to access optical drives.

Here's a little more information about it.

 

The netbook doesnt have any physical drives for burning but it does have alcohol installed for mounting images.

 

Start the computer in Safe Mode with Networking by pressing F8 as soon as the Windows Logo shows. Uninstall Alcohol then after restarting in normal mode, try re-installing Alcohol so everything including sptd.sys is new. If it works, you'll have to do the same with the other drive. If not, there is other image mounting software that other posters can recommend — unfortunately, I'm not familiar with them so, I can't point you to any specific one(s).

 

I cant even boot in safe mode. Can I delete sptd.sys or would I need to alter boot info to avoid looking for it?
