Try a smc reset:
Will it safe boot?
Boot up holding left side shift, this will take a little longer, but will run only essenctial applications, letting you know if it could be a 3rd party application.
Boot from CD just hold C.
recovery boot command R
Tried the SMC reset, safe boot, CD boot, and Recovery boot all with no luck. Not sure why it's going on, but it's looking more and more like a hardware issue to me. It's a white screen (instead of a grey screen), so I'm worried that it's something with it. I'm going to try and see if I can remote into it using Screen Sharing to see if it's something with the display.
My wife used it last and she told me that it was slow on the internet with the mouse freezing up, so she held down the power to turn it off then it came up with the white screen which hasn't come back on since. I'm using an 3rd party SSD hard drive and replaced it with another SATA hard drive, but it didn't help.
