I did try a few things last night.
I installed Steam on my Laptop - which I left on Wireless and it worked perfectly fine. So it's not a connection problem.
This morning it actually worked for about 5-6 minutes, enough to download Torchlight 2 and half of Shadowrun Returns before it went 'offline'. Yesterday it only lasted 10-30 seconds!
There is 1 thing I'm thinking though...
I'm wondering if it's the install of my OS. I've tried it 3 times but when I install it again, there are still a load of settings and stored files from when I last used my PC in 2013. Already 200GB used up on the HDD after a fresh install.
How likely is it that this could cause problems with Steam when it's looking for file locations etc?
I'm running 32 bit windows, but it stil lcreated 2 program file folders, one with (x86) next to it. Steam installs in the other one which is weird as that's the 64 bit file...
1 other thing is I have a guest staying for 1 week and I noticed when I created my home network, it was asking ME for HIS password so I wonder if that could be creating some kind of problem.
Not sure why the Laptop would be fine in that situation though...
How can I completely wipe Windows 7 and the HDD in it's entirety?
I tried the command prompt method I kept seeing online but the commands just do nothing for me when I follow the step by step guide.
I'd like to wipe it clean, 100% and just truly install everything from scratch - currently I'm just installing it and it's keeping all the files from the previous version when it wipes it.
