Windows won't start, is my PC ruined?

[AshyCFC]

So, I currently have the following system:

FX-8320 with a TX3 cooler
HD 7870
970series gigabyte board
550w xfx
8gb ddr3 1333mhz
1tb hdd(it's only 5400rpm)

I've got it housed in a Corsair 300R case, so plenty of space for parts.

I've been looking at this bundle here:
http://www.cclonline.com/product/186702/NoMfgCode/Motherboard-Bundles/CCL-Skylake-i5-mATX-Motherboard-Bundle-/MBB-1151-i5G/

I5 6600K + Gigabyte Z170M-D3H+8GB DDR4 2133mhz for £365

The reason i'm looking at upgrading is because I'm having a fairly big issue with graphics card artifacting on the main PC and NOTHING i can try to do to fix it seems to work. Wipe HDD and Reinstall windows didn't work, I've tried multiple graphics too including a 6770 and an old nvidia 8800gt, different HDMI's and I'm flat out at the point where I think there must be a problem on the motherboard end?

Infact, the entire system is refusing to start windows(it turns on and says windows failed to start) at this point. I am going to try and install linux on it just to see if it can do anything

Any advice on what I should do, should I go with the bundle and upgrade my parts? Take it to a shop and try to get it fixed(although they'll probably just tell me i need new parts anyway?) Or something else.

Oh i've also run Memtest86+ and it passed 100%

I assume you meant screen artifacts and not graphics card artifacting specifically. If you're seeing artifacts with multiple GPU's, the issue's not with the card.

Few other things to check.

- remove CPU cooler. Clean &reapply thermal paste.
- Is your CPU overclocked? The X3 cooler can only handle wattages up to 130, which barely covers a full-running 8320 at stock voltage (125w)
- run CHKDSK on your HDD. How old is it, by the way?
- update the BIOS of your motherboard
- clean system fans & dust filters. make sure all are spinning at spec'd speeds.

I don't have any overclock, I've tried reapply stock cooler again anyway just for test and no luck.

Can't lload windows to run CHKDSK, it's around 5years old.

I've cleaned out the dust and all of that stuff.

You can run CHKDSK from a win 7 disc or bootable USB.
