IOk so I will try to explain this as best I can. For a while now. My pc would shut down randomly without warning. The power would just cut out. I lived with this bevauas I could not solve it. Now the othwe day the pc froze. I got horizontal crazy lines everywhere and it crashed. I havent been able to boot up since. I instantly put this down to the gpu but I have been trouble shooting and discovered some odd things. If I run windows memory diahnkstic it says I have hardware problems with memory. I have tried booting with each ram module individually and no difference. Does the widows diagnostic test video card ram. And is this what it has found problems with? Also. how I haveit set up cable wise originally it loads but then I get artifacts everywhere and have tk restart. I switched the 8 and 6 pin power connectors for the gpu. I moved them at the psu end to the 8 abd 6 pin modular bits beneath the rail they were on. And if I do this. The system tries to power up but then powers off straight after and cycles through this. What is myproblem? Will a new graphics cars fix this?
