GTX780TI SLi not showing up in Device manager? :/

[Sam780TI]

hey guys

the last few months i have experienced some sort of strange problem? my windows has had 2 random shut downs while idling on my desktop, i uninstalled all drviers, then installed again and rebooted and somehow it showed back up on my device manager? then today again? i came back from the kitchen and my PC had reset itself, i go intio Nvidia control panel "no SLI option" and Device manager is only picking up 1x 780Ti ? :/ have tried unistalling again and installing ect but this time no change, also tried a new SLI bridge but that wont matter as its not showing up in Device Manager now!

i run a MSI z997 Mpower Max AC motherboard

i also used a cheat for a game i play? and in order for windows to boot up with the cheat drivers i have to press F8 before window launches and select "disable driver signature enforcement" i have noticed the issue with resetting ect has only been after i have had to boot up using this
method? so im now going to system restore and be done with the cheat, and see if this was maybe the issue

thanks for any help in advance guys

i fixed it!!! i removed PCI-E and system/launch repair and it works fine, must have been that driver signature enforcement bugging out my system and OS,
