Gtx670 artifacting and causing bsod's?

Hi everyone,
I own an air cooled Gigabyte 2gb gtx670 which has never been overclocked or tweaked in any way.
Recently, cs:go has been crashing alot and with open hardware monitor open on my other screen, i noticed that the load is at 100% and around 70-80 degrees, this is with both medium and high settings. At low settings it sits at about 50%, but cs:go isn't an intensive game?
For the past two days, once a day i have experienced a bsod reading clock_watchdog_timeout, which leads to one of the threads on my cpu being faulty. (CPU: i7 3770k @4.5ghz 1.240v stable, idle around 30 deg, 70 under load)
Today I wasn't able to boot into windows so i did a reinstall, hoping any faulty drivers would clear up, so i reinstalled the necessities (cs:go and nvidia experience) and launched cs:go. There clearly was something wrong as there were many white bars dancing around the screen and artifacts all over. The gpu was only at 50% load and 50 degrees so i assume heat isn't a problem.
The artifacting happens in other games such as tf2 etc.
Any idea what is going on or what i should do?
All i can assume is both my cpu is damaged (from the bsod) and my gpu is also damaged (artifacting).
I am a doing my HSC very soon so some help would be very much appreciated :)
Many thanks :)

Solution
Well Furmark doesn't exactly put a big load on the CPU so 70 might be a bit high for Furmark ... but other than that all is fine.

Card came out in May of 2013....so time to RMA.
1. Run Furmark for about 20-30 minutes with HWINFO running. Pay close attention to the 3.3, 5 and 12 volt rails and look at the min and max columns at the end of the 20-30 minutes. You are looking the % voltage variance.

For example, let's say you see a minimum of 11.35 on the 12 rail,

12.00 - 11.35 = 0.65
0.65 / 12.00 = 0,054 or 5.4%...bad

Absent voltage instabilities, I would say that your GPU is shot.

Yep, running furmark now, not really sure what im looking for in HWiNFO but ill send a screenshot of the System Summary, is that what youre looking for?
Thanks

Furmark has been running for 5mins or so and I'm not really sure where the power section is, any pointers?

These are the voltages after 45mins or so of running furmark, never goes below 12.096v.
When the stress test was starting up i could definitely hear some sounds coming from the video card, sounded alot like parts of the card were expanding due to the heat. Sounded like it was cracking but as it still works I assume its a normal sound.
Seeing as the PSU is giving a stable voltage on the 12v rail, would you think that the GPU is giving up with all the symptoms from the original post?
Thanks

CPU: @4.5ghz 1.240v Idle at 37degrees, 100% load at 70degrees
. @3.5ghz stock Idle 30degrees, 100% load at 57degrees
GPU (not overclocked): Idle at 29 degrees, 100% load at 70degrees

I wouldnt have thought these temps were anything out of the ordinary, what are your thoughts?

Thanks

70 is when running prime95 doing a stress test, pretty sure those temps are ok.
Yeah i bought the card through scorptec so hopefully we can work something out. :)

Thanks for your help dude, really appreciate it :)
