After the previous advice i got here:
I am now past the hardware issues i had. I am however still using my dell as i cannot get into Windows on my new PC. Basically, when i power on the PC with my old 8Gb hard drive connected (which has windows XP installed on it), it will ask me if i want to run Windows. When i go to load up Windows, it gives me a blue screen saying that Windows has stopped loading as there has been a device failure.
It then asks me to clear the Hard disc of Virus' (which i can't do as i can't get into Windows). It alternatively asks me to ensure the HD is connected properly (which it is) and if it has any errors (which i don't think it does as i'm using it now with no problems).
If i try to use it with my brand new 80Gb hard drive, it asks me to insert the correct boot media to the correct boot device. I can't find my Windows XP disc but i do still have my windows 98 Floppy and CD-Rom however it is attempting to boot from the floppy drive and when i put in the "Disk 1 - Setup" floppy, it says it's an invalid system disk. Please remove and replace with the boot disk.
What do i do? If you need me to type out EXACTLY what it says when i try to run it i can hook up my new PC and write out what it says (such as any Technical messages ect...)
