Hey guys, first up, here's what i'm working with: http://uk.pcpartpicker.com/user/codecay1/saved/2Uet

This is the first PC I've built, and you can probably tell I'm no expert.
When it came to installing windows updates, it just didn't like it. After going through the second or third update-restart process, the screen went black at the log in stage. Sometimes it didn't even get that far, and told me it just couldn't find anything to boot, or didn't tell me anything at all.

I repaired (came up blank), and started in safe mode to undo the update, so that the PC would at least run.

And it kinda did for a bit. It didn't look very good (graphically), but it was running.

Then I installed a Direct X update, and it stopped being able open skyrim or borderlands 2 even in the lowest settings and smallest resolutions.
On the most recent attempt it crashed, closed the game, black screened for a couple of seconds and told me that my driver failed. I think it said my AMD driver, but it disappeared almost straight away, so i couldn't read it properly.

I figured I'd restore my system again, but this then failed, and caused another struggle to just get it to boot again. It's driving me mad.

The answer is quite straightforward. Either your video card or your motherboard is defective. You're not doing anything wrong or out of the ordinary to cause what is happening. If everything you've written is 100% accurate then my suggestion is to try using a different video card. If nothing changes, then your motherboard has a problem. Try updating your BIOS to the latest release. If putting in a new video card fixes the problem, then the video card is defective. You have a hardware problem here. A software problem would require that you did something to cause it and from what I've read, that's not the case.
with your new build install the amd chipset drivers for the mb from amd wen page first. then the sound and network drivers. (newest ones from online) the the gpu drivers. when you do the windows updates do one update at a time not 10-11. reboot betwee nthe updates and dont install the hardware updates. you already have the newest drivers.

Could be a hardware issue.

Download memtest - http://www.memtest.org/#downiso
Burn it to a CD and boot it up to check your memory modules for any errors.

If no errors are present, I suggest downloading prime95 (cpu stress test), hwmonitor (temp monitor) and cpuz.
While testing with prime, check hwmonitor if cpu temps are ok (below 70 should be fine) and check cpu frequency and voltage with cpuz (3.5 - 4.1ghz and around 1.35 - 1.4v).

Also enable S.M.A.R.T in bios and check your hard drive health with a software such as CrystalDiskInfo http://crystalmark.info/software/CrystalDiskInfo/index-e.html

Please post back any questions / results.

I was really hoping this wasn't the case. I've already had to replace a faulty mobo. I don't have any other video cards, so i can't test this. I might have to take it to a repair shop. Is there a way of checking whats faulty without replacement parts?

Is it possible its a power issue? I'm using a molex to PCI converter to power the 2nd PCI slot on the graphics card, but i know my psu isn't the best, and i probably should have got a bigger one.

Also, this might not be relevant, but when installing windows i had lots of issues, eventually solved by configuring my SATA ports as IDE, as they just wouldn't work as AHCI.

You can't check the motherboard directly, but since the answer isn't that straightforward as Avro is saying, I suggest you test the easier-to-test hardware parts, such as the cpu and memory, before disassembling your entire machine.
