Hi. I am having a problem with a brand new computer from day one. I ordered a new computer from a reputable manufacturer with an ASUS X99 motherboard, Samsung EVO 850 SSD hard drive, Geforce 980GTX and 16 MB of system memory. After the very first boot which was successful I am experiencing frequent freezes at the windows starting screen, either before the 4 orbs animation begins or during the animation. Only option is to hit power button and reboot. All drivers up to date, tech support has had me disable the "professional" overclock of the CPU (Intel I7 5930 at 3.5) and GPU, do a 5 and 1/2 hour memory check, run sfc /scannow as an administrator, chkdsk on reboot and no errors are found. they are shipping me a new hard drive to try. Any ideas? Have I done everything to ensure it's not a corrupt windows install? Sometimes it boots fine but never consistently. Thanks in advance.
