I just built a new machine because the one I had for years quit working properly. It would start up run for a while and then as soon as I installed a program downloaded something tried to uninstall something. It would freeze up, still allowing me to use the mouse click on certain things but ultimately I would have to reboot because I was unable to do anything else. Once I reboot I immediately get a bsod. Safe mode nothing else would work so I would have to re install windows thought it might be the hard drive replaced it had the se issue. Was older components so I decided to upgrade. Upgraded to a i7 4771 don't do any over clocking, so wasn't interested in the k model. So I have kingston hyper x 1866 2x8 gig ram, asus 280x graphics card, antec 850 true power quatro psu, asus z87 pro motherboard, samsung 840 evo ssd, western digital black 1 tb hard drive, and an antec 1200 case. Got everything installed set up and rocking and it is doing the exact same thing. Have tried using the western digital and the ssd both as the primary boot drives and get the exact same problem. the power supply is a refurbished one I got from amazon other than that everything else is brand new. Any ideas?
