Nexus 7 2012 not used for 2+ years, USB driver and MTP problem help!

[L27x]

Hey guys, my nexus 7 is rooted operating AOSP/AOKP on 4.2.2 just to give some breif information (it's not fresh in my mind and I plan to clean install a new rom and kernal).

So first I'm not getting my nexus to display in my computer (win 7 x64) as MTP with usb debugging enabled nor disabled. PTP camera mod works and displays. I've already googled around so I know a few basic solutions to this issue none of which have worked thus far.

Following Nexus Root Toolkit driver instructions.
After wiping the drivers a windows restart and disabling debug mode, connecting via usb only installs the "Android ADB Interface" driver only (step 2 link above). After switching from MTP to PTP Nexus 7 driver is installed only (step 3). I then re-enable MTP where no new driver is installed untill usb debugging is turned back on and Android Composite ADB Interface driver is installed (step 4 + 5). This is where I'm stuck... At one point while playing about I managed to get MTP in the taskbar driver installer only to fail "No driver found" or something along those lines.

Please can someone assist me I need this tablet wiped and operation ASAP.

Thanks anymore information required just ask.

Update
(Thanks for the forum relocation)

Have now flashed the latest TWRP, along with OctOs 6.0.1. I alter and update the drivers, I've tried multiple usb slots everytime it manages to seek for the windows update MTP driver it fails to implement a driver, making it impossible for MTP through windows explorer, is this just meant to be or is something going wrong here. Any help would be greatly appreciated. (I can still push/pull files via ADB.)
