System Working fine but reboots to system restore

Hello,
I will try to explain this as best as I can so if you need any more information please ask and I will gladly answer. If this is in the wrong forum I apologize. If it is please redirect me and I will post it there.

I have built 11 computers, all containing the EXACT same hardware and software. I install windows 7(64bit), all the drivers for each component, and activated the copy of windows. The pc will run completely fine running any program I ask it to. The problem does not happen until I reboot the computer, now this is not always on the first reboot. These computers could last a few days and then I reboot and it all breaks. When I randomly reboot the system it will boot up showing problems and asking for a system restore. So I do the system restore and reinstall a few drivers and the same problem will persist.
I eventually get fed up with the whole process and decide to completely reinstall Windows thinking maybe I could have done something wrong(been doing this for 15 years no problem but it happens). After a completely random(as far as I can tell) amount of time and reboots the system will do it again. I am completely stumped on this issue and could really use the help. I have managed to get 2 working for a few weeks now but they hard bent cpu pins from the factory and I straightened them out. The other ones I have checked and they are fine(so it seems).
The System is running an ASUS P8Z77-v PRO motherboard, EVGA Nvidia 650 TI graphics card, i7-3770 CPU(may be another i7 but all the ones I have been using have been this, so it is safe to assume that is the one I am using), pci serial port, National Instruments sound input card, 16Gb DDR3 1333 Corsair XMS3 ram, Corsair TX850 PSU.
I have a fairly high knowledge of PC's and troubleshooting but with this problem I am completely stumped. Any help would be GREATLY appreciated.

Check your ram.

Also check the hard drive with the manufacturer's diagnostic tools.

I have checked the ram with the basic memory test and the results seem to be inconclusive. Tried new ram, same speed but different manufacturers and came up with the same problem.
Could I have bought 11 sets of bad ram? or the wrong ram in general? The hard drive test I have not done but can attempt to do so, I just don't see 11 of them all being faulty. Although they are from the same manufacturer, purchased at the same time(so could be from the same lot). I will see if I can get the hard drive diagnostics started to either rule that out or solve a problem.

Why are you applying dated XP installation methods to a driver-complete OS? Forcing a bunch of drivers on Win7 is the cause of many issues seen here.

Instead put your network driver in the backup so if it isn't provided during install (plug in by wire to increase the chance) you can install it to get online, enable Automatically deliver drivers via Windows Update (Step 3), then run all rounds of Important and Optional Updates choosing everything except Bingware.

After each reboot check for Updates until there are no more offered then check Device Manager for any missing drivers to import, no more. Only if performance points to a specific driver should you import any others, since all drivers are tested in Win7 to determine which should be used and only those pushed through via Windows Updates are recommended.

If you think this is strange, consider that there is no user participation with drivers in Windows 8, using technology that was developed in Win7. But since Win8's release all Win7 drivers have been vetted.

Other tips here to get and keep a perfect Clean Reinstall - Factory OEM Windows 7 are the same for retail, have been used by a million consumers without a single complaint.

Will give that a try. Not arguing with you but I have done the exact same thing on 30+ machines and the only difference is the motherboard on these 11. Could very well be a problem in my installation of the drivers so I will try what you suggest, will post results after I can get this done.
Thanks

I am an installation specialist so will always look at that first, however you can eliminate both the OS and HD as your problem by running for awhile with a boot disk like https://www.sevenforums.com/tutorials...cy-backup.html with the HD unplugged. If problem persists then it is other hardware and you can not worry about the OS or HD.
