Windows 7 White Screen On Boot

I have found at least one other person that had a similar problem, but the information you provided for that problem doesn't seem to fit my symptoms. That person was seeing the message "please wait while connection is being established", I am not getting any messages, just a flashing black to white screen that stays white.

When booting, my screen will flash white. If the boot is successful, which is less than 50% of the time,I then see the loading windows screen and the computer goes ahead and boots normally. But, more often than not, I never see the booting windows screen and the monitor will just flash from black to white, several times, and then stays white. I do get the windows music to indicate that the boot was successful,but I can only see a blank white screen, no icons or mouse cursor. If I press the power button a couple of times, the system will usually eventually give me a screen that looks like the system was paused and is waiting for a user to be selected and a password to be entered. Once I am able to access the system, it seems to work normally. I have waited as long as 15 minutes or so to see if the boot will complete once I get the white screen, but it never seems to go any further.

I have checked for a virus using my virus checker, Viper antivirus, and checked for malware using malware bytes, but can find nothing. I even started a boot log to see if I could see any indication in the log file, but I can see nothing.
