Need urgent help with my GPU; at the end of my tether!

Hey guys, I just bought a new gaming rig for ~£1000 with a Zotac Geforce GTX 760 in it. For the past week (since I bought it) I've had consistent, daily problems with it. My display will often go black, or have white bars criss-crossing the screen, and proceed to require a system restart to function again. A loud constant 'glitch' noise will generally accompany this kind of crash, but not always. It will occasionally be 'broken' when I power up the system, with the screen criss-crossed with white bars, and when I log on to windows, it will appear 'broken', the colour palette will only consist of basic colours (mostly pinks and teals) and the resolution at the absolute smallest possible. This problem will NOT go away after a system restart, essentially locking me out of my own computer until it decides it's in a good mood.

I've suspected it to be a driver fault, but I've re-installed drivers three times to absolutely no effect and I'm honestly stumped and need help.

I'm running this PC on Windows 7 64-bit. Please can anyone offer support and/or advice, it's been doing this up to 10 times a day and it's absolutely gutting and frustrating to buy a system for ~£1000 only to have it not work!

Sorry if there are any spelling errors; typing this on my phone atm, PC is having an off day.

check monitor cable at both ends.
try another monitor cable.
try under clocking the cards ram and processor 50mhz each.

How would I go about doing this?

Try a different cable, update drivers alough if it is doing it at the Windows when your booting up it prob isn't the drivers but it won't do any harm to give them a go anyway.

If you haven't overclocked the card don't bother underclocking it as it shouldn't need it.

Take it back to the shop if you have a warranty on it.

if the under clock helps............ rma the card or return to point of purchase for a new card.


before you do anything.......... please list all hardware in the case. include the power supply........... and monitor resolution.


Monitor resolution is 1920x1080.
PSU is a Corsair 650W.
CPU is an i5 4650k, overclocked to 4.1GHz.
8GB of Corsair 1333 mhz RAM.
Mobo is a Gigabyte model, can't remember the exact model name.
Got a 1TB Seagate HD and a 120GB Intel (I believe) SSD, where my OS and drivers are installed.
The card was/is NOT overclocked at all.

Tried re-installing drivers from nvidia.co.uk and the disc provided to me by the manufacturer multiple times to absolutely no effect.

I got this rig from DinoPC.com. I know I have a warranty, but I'm not EXACTLY sure what to do with it, since I can't just 'take it back to the shop'. I've complained on their forums, no reply as of yet.

forgot to mention............ go to windows update. sometimes people who build machines get lazy............ look for netframework updates and patches............ but install other stuff that is there............ then do a reboot and go back to see if there are anymore updates.

UDG............ under-clocking will help determine the health of the card. I think the zotac comes over clocked doesn't it?

also, try an SSD firmware update.

I had to completely re-install the OS for several reasons related to start-up when I first got the PC, so the manufacturer isn't really to blame in case it's the OS' fault. However, I consider my installation of the OS a success; this problem doesn't ALWAYS happen, most of the it's well behaved and acts like a regular PC, but 5-10 times a day it will crash and/or the display will become mostly unusable.

regular healthy PC's don't crash at all.
