I just recently bought a 4670k and a Gigbyte z87m d3h mobo, i had a 670 prior to buying this setup and have had no problems the past 6 mnths or so with it. Ever since putting my new system together I get random video driver crashes , the performance is fine nothing is over heating everything is updated drivers and bios wise, I have run spyware and virus checks which have come back clean, I have run cpu,memory and gpu stress tests which dont cause any BSOD and I had no driver crashes while running these tests oddly enough... Anyone have any idea what could be causing the problem is it just nvidias drivers are not working properely with haswell atm ?
