Hi there, First of all, english is not my native language, so, I appologist for mistakes in advance. PC: i5-2500 3.30GHz GA-P67A-D3-B3 Bios F6 (updated today, before, with same issue was F5) 2 x 4GB G.Skill RipjawsX DDR3-1600 1.5v Cooler Master GX 750w 80plus EVGA GTX 560 1GB (I tried with another one geForce ¿? same problem) WD Blue 1TB (I tried with another one Seagate Barracuda 1TB and another one and nothing) CM storm Tactics with 4 funs No OC never. I am having BSOD in my PC every time a try to install OS. Problem start some days ago, my PC was working ok for more than six months or nine, don't remember, no problems indeed. Theme is that I don't remember what I do to have my first BSOD, maybe VGA driver, not sure, first times I had some day between BSODs, last days, can't start OS. I tried reinstalling OS, one of that times I can use it for a couple of hours and same problem again. Tried changing HDD same problem, changing VGA same problem, but last time I get jump OS install everything was OK but when update VGA driver some mins after i got BSOD again, my guess is this driver, i found something in the web about similar problem with GTX 560 ti, in Nvidia forums recommend to use 314.22 driver... this is my next move, but now I can't install Win 7, in this moment HDD is IDE, I tried AHCI but same thing, I can't load OS in any mode, can't finish install... and my knowledge is over. Some help? Thanks in advance.
