Windows Updates not inst/dling properly (800B0100 + 80070643 + others)

Hello,

Just purchased a new MOBO and some other new hardware a couple of weeks ago. I am using the same Windows 7 Pro copy I had on my previous mobo and HD. After I installed Windows 7 Pro onto my SDD (with a HD as my secondary storage), I was getting BSOD and SP1 would not install (but other updates would prefectly fine). I re-installed (cleanly) Pro a couple of days ago. Now, barely any of the updates work. There are various failure codes, such as the ones in the title--and no distinct problem.

I was able to download some updates by only selecting 1-3 at a time. However, with 118 updates...I eventually lost my patience (plus, sometimes a few would still fail even at only 1-3 at a time).

The failure process at first was at the download stage - the progress would freeze randomly at 7% or whichever. After several more attempts it got through to the installation phase. Now installations randomly stop at a random file. Upon restart, Windows fails to configure updates and nothing is accomplished.

Now a weird thing is, that with some of my larger files (2+mb), I will sometimes see like 5.1mb - 10mb for the listed file size. Also, on my main Windows Update screen (the one which lists how many important and optional updates you can download), it says "79 important updates selected, 236.2 MB - 1,059.8 MB."

I have tried:
-FixIt
-Deleting all temp files
-Deleting DataStore

Any help would be appreciated. Sorry if my post was long-winded.

Random Specs:
Windows 7 Pro
ASUS P8Z77-V Pro
Samsung 830 64GB SSD

Attempted to download it and during the updating phase it stops and gives me the following error: "Update installation failed. Error information - 0x80070002."

Hey Jacee thanks for the reply again.

The manual fix didn't work for me either. Things started out well, was downloading 84 updates and after about 35%, the updates suddenly went to installation. Of course, the installation got stuck at 29/44 (so only 44 updates were downloaded or so and the other 40 weren't...). None of them installed successfully.

Once again I still see a weird glitch on my Windows Update screen. It'll say "Windows Service Pack I 73.4mb - 825mb" (or something similar to that).
