after i ran the memtest this night (10 passes 0 errors) my monitor would get no signal at all, i rebooted at least 15 times and then opened my pc up to check if there was something wrong, i found some major dust all over the motherboard (including pci-e slot) and a little bit on my card, cleaned it all off and it started normally again. im gonna try see what happens today
i forgive you ivan :0
