I've had this desktop computer for nearly 2 years and it runs fine most of the time. But when it's been off for a while and is turned back on it regularly freezes a different stages of booting. Sometimes it freezes at the BIOS boot screen. Other times it makes it all the way to the graphical desktop. But it typically takes half a dozen attempts until it's fully operational.
On rare occasions there is a clear video card failure. It's obvious because the screen will suddenly change colors or display random noise. The video card is an Nvidia GTX 760.
I'm not sure if the boot problem is video card related because it often stalls on the ASUS logo. I'm running Arch Linux and have had stability problems with both the Nouveau and Nvidia drivers (currently I'm running Nouveau).
