It's ok now, what I did is download the system image at midnight as there's less people using the internet and therefore less traffic to interupt the download.  I downloaded it at midnight and it succeeded, so for those struggling to download a system image for their PC, I would suggest downloading it somewhere close to the off-peak hours. 
I am trying to download my PC's recovery image operating system from the dell drivers uk site under the product I own (inspiron 7459 aio) Whenever I try to download the image, it fails in the middle and the entire image file is corrupted, it always happens whenever I try downloading the image and I seriously need that image. My PC has now gone unstable, I had to do a clean install of windows 10 but every few months it gets corrupted with lots of drive errors, this pc was working perfectly with no errors before dell told me to delete the recovery partition, the dell technical support ruined my computer. Can anyone please help me? How do I stop it from failing in the middle of downloading? I feel like this system recovery is my only hope to get my PC back to the state like it was when I first got this PC. (If this is not sorted out then I am no longer satisfied with my PC and will just return it and get a refund, because even the technical support will not help me out and instead bribing me saying I have to pay for the mistake they made which I will never do!!!) 
Help! I cannot download my PC's system recovery image from dell drivers website
