In some games like GTA IV, BioShock, Splinter Cell Conviction, Sniper Ghost Warrior 2 I get bluescreen after some time. My specs are the following. G3258 @ 4.5GHz, ASUS Z97-K, Sapphire R9 270 Dual-x OC 2GB (overclocked at 1050 MHz with MSI Afterburner), HyperX Blue 4GB DDR3 1600MHz, Seasonic S12II-430W Bronze, WD 1TB Caviar Blue. Now, I have the latest BIOS and GPU drivers, at first I thought it was the CPU but right now it's running with 1.375 v and I ran a lot of stress tests and there were no problems but in gaming, as I said, I get bluescreen. Can the GPU be the problem ?? How can I find where's the problem ?
