Graphics Green lines on startup

I turned on my pc earlier to be confronted with a lot of green lines and artefacts as it booted:



it is a GTX 670,

any ideas on what I can do or is it screwed?

 

ok more info - swapped in an old card and the system started fine... guessing it is the gfx card then

 

Yea, your graphics card is faulty. Those are the signs. :/

 

hmm guessing as the old card works it cant be power supply... well this sucks

 

If it was the power supply, the system would shutdown when you play a game.
Here you are at idle.

 

Well RMA process begun with EVGA, will update this thread with progress if anyone reads

 

wel rma it or bake it

 

Does it happen every time? Sometimes I get something similar at the very top of my monitor. I switch the monitor off and on again and it goes away.

 

Just had the same thing on my graphics card, a GTX560ti, had no picture when my pc was plugged into my AV system, so i plugged it straight into a TV and had the same type of screen artifacts and lines as you.

I tried the DVI port on my graphics card and it works fine, turns out the HDMI port was knackered, its the second 560ti Ive had that has developed a problem with the mini HDMI port

 

Update - received a refurbished card from EVGA - put it in my system and there was no green lines (YAY), but idling at 65 deg

I then loaded a game (Civ V) and it decided to crash my system, with the fans on the card blowing hard.

guess time to talk to EVGA again

 

Is it clocking down properly when idle?

 

on start it reads 67 degrees... doing nothing evga reads 38 - 40 (watched for 1 min)

refreshing my windows experience (only thing I thought of) it goes straight up to 102 degrees and the system restarts
