Windows 7 StartUp Repair, Custom Build Problem?

Hi All,
Recently built a gaming pc for myself, and installed everything I needed, windows, motherboard installs, graphics drivers etc. and everything works fine, until the second time I restart my pc, it does 10 updates, then shuts down and fails to load windows again, stating 'startup repair is attempting to fix the problem'?
One time it says that iastor.sys is corrupted, but when trying to reboot from a recovery disc it says there is no problem with windows at all! In addition to this, when trying to boot from the hard drive again it says 'startup repair was unable to identify the problem'
I have checked all the connections on my gear and cannot make any sense of it, searched on the internet to find answers but most relate to laptops, and hard drive failure in older ones... But all my parts were only put together on monday!
Here is the specs, if it helps:
CPU: I5 3570k
Cpu Cooler: Coolermaster Hyper EVO
Motherboard: Asus P8Z77-V
RAM:Corsair Vengeance 8GB
PSU: Xigmatek 700w Centauro
Case: Zalman Z9 Plus midi tower case*
HD: Seagate Barracuda 1 tb
Disk Drive: LiteOn IHAS124-04 Sata

*Of specific note due to how the hard drive is housed, as many have said that problems may be caused by the harddrive, yet I have found no issues with it.

Any information that anyone can give that would help me solve this without another fresh install of windows would be greatly appreciated!

  1. I had somewhat the same problem. I would freeze up when updating windows and there was no apparent problem. The way I solved it was to go back and reinstall windows, install drivers and then install windows updates, but I would only update a few files at a time. I found that when left to do the massive update you need, it would "overwhelm" the system and it would crash like yours. Takes a little longer, but I got mine up and running the first time I used that method.

  2. Thanks, it works normally after installing updates through windows update,it has been the 2nd time I have switched it off each time it attempts the 10 updates, gets to update 10, shuts down, then is unable to reboot. Could it possibly be due to having automatic updating switched on?
  3. I never use the auto updates. I check once a week and pick the ones I want.
