Weird Purple Lines...

I get these weird purple lines appearing randomly on my PC, specs in the sig. I have installed the latest drivers from nvidia, flashed my motherboard bios to the latest one, and yet they still occur. Usually when these lines appear, the screen will go blank and I have to restart it from the power button. Then when it reboots, windows will disable my 580. The weirdest thing of all, this doesn't happen when the GPU is stressed. I played an hour of BF3 and it was fine, after I quit the game and did some internet browsing..purple lines...its very odd.....
 
Sounds like your VDimm is on the way out to me. Could be wrong though and another member will put me right.
 
happened to me recently on my old card, was definately VRAM but it had done me well over the years so I just bought a new one. GIven your circumstances def RMA it as almost certainly the VRAM.
 
I just read somewhere that this can be caused by cards being underpowered...my gpu takes two 8 pins and I have it connected to a single 8 pin and a 6 to 8 pin converter. Could this be it?
 
not too sure to be honest but when I forget to plug in the PCI power cable into the card I get a warning that it may have insufficent power but it runs fine for general windows use. Never really tried much else when I get the warning I shutdown and plug it in.
 
It's possible (although unlikely given your description) that the monitor cable you are using has some damage. if you have access to another one try that out and see it if helps.

That shouldnt make a difference really, aslong as your PSU has enough power(What PSU you using?). I would say dodgy card or dodgy cable to monitor.
