Please let us know how you get on!

Once you have got this sorted out it might be advisable for you to complete your system specs in your profile so people can see what specs you have therefore making it easier to help you in the future.

Here is a link that will easily allow you to do this and even fills in your system specs in your profile:

System Info - See Your System Specs

I hope this helps!

EDIT:

Just had a thought, a long shot I know!
Do you think it could be the Video Card or Driver?

It absolutely will not boot from CD, it tries but it just leads to a blank screen with the arrow, I've left it for ages and it doesn't make any progress so I can't even use the repair tools. F8 repair option does the same thing. It's a bit of a head scratcher!
I concur, but if there are issues booting from other devices (USB or CD) as well my first suspect is the RAM.

Just getting back on this (had some other things going on)

To answer a few questions, this isn't referring to my laptop, this belongs to someone else and it's not a rush job (which is handy!)
I will fill in my own specs based on the machine I usually use.

I have a quick question before I do anything else. If I put the HDD in my own laptop (taking the primary and secondary out first) can this cause a problem? I'm only asking as I did this a few years ago (only with a desktop so no meaningful difference) - I took my own HDD out, put the suspected faulty one in, still wouldn't boot so figured it was dead. Then when I put my own back in (my machine) I had all sorts of weird stuff going on and it was a headache to fix. Coincidence? Or is there some issue with doing this?

Thanks again peeps!

I know this will seem like an Over Simplification, but....when all roads lead to Rome, go to Rome. Eh?

What is common to booting the laptop for any device? HD= NO, RAM=probably NO, so what is?

The answer is the bios. I'd go right to the CMOS battery. Take all external power off of the unit. Remove the main battery, and then find the CMOS battery, and just replace it or at the very least, check its voltage.
In every system I've ever worked on, and that's a bunch, the CMOS is held up with a 3.0vdc battery. And if the battery voltage is not at least 3.0 volts, (or more) strange things can begin to happen, from failure to boot up at all, to BSOD's, crashes, etc.

When changing the CMOS battery, take out the old battery, and wait about 30 minutes before installing a new battery. That allows the memory cells in the CMOS to completely drain down to Zero.

Twice in the past week, (yes, I'm a working PC Tech) I've had two computers that either would not boot up at all, or boot up and then do weird things. In both cases I fixed the PC with a new CMOS battery (CR-2032).

So I'm just offering that as a possibility, based on 30+ years of experience. (and dozens of PC's that I've fixed with nothing more than a new CMOS battery.) If that works for you, it's a cheap fix.

Good Luck Mate!

How are you going to run that, when the OP has plainly stated that the computer will not boot from any media.

Maybe, read before you post?

How are you sure with no tests? What you state is a good possibility, but RAM is quite commonly the cause.

My opinion, TechnoMage2016 and Axe0 are most likely correct about possible cause. RAM or BIOS battery.

Quick update - just had the RAM out. It has two sticks of Samsung 2GB (as in 2GB each) - tried them one by one and no change.

Next stop CMOS battery. If that doesn't work I'm stumped and would lean towards a deep fried hard drive :/

Have you tried them in all slots?
