Error code: 0x490 Windows 7 freezes at startup.
Original Title: Start Up Windows Freezes, only works on the third time starting CPU.
I am having problems with my PC booting up properly.
I get to the screen where it says starting windows and it will get stuck with a small red dot above the words.
I will then have to hard shutdown and it won't recognize my keyboard on the next startup
so then I have to hard restart again and then I can get it to the log in screen and use the PC normally.
I have done a system restore from a date before I had the issue and that did not work.
If I run the system repair it fails and it says there is 1 root
cause and gives me the error of 0x490.
Sometimes it will tell me that a driver I recently installed may be causing the issue, but then I went through all my drivers and checked for updates and still have the problem.
I am currently running
the Seagate disk checker utility to check hard drive functionality.
My question is how do I get my computer to actually work right?
