I have a problem starting up my Vista. It's a vista ultimate and I've never had a problem like this till fairly recently, I turn on my PC then it proceeds to the loading screen. One second later it gets a blue screen and restarts. Then it shows, Windows is unable to load with options of starting it on Safe Mode, With Last Known Configuration and Normally. I choose normally and it did the same thing, then I did a repair with the Vista CD, it started up normally after then.
But when I turned it on the following day, it does exactly the same thing. But this time, I choose to load it up on normal and I repeat it like 3 times before it finally boots up. Then after signing it, sometimes I get the same blue screen and it reboots again. This has been going on for 3 days now and frankly it's gotten quite irritating and I worry constantly that it might crash permanently and wipe out all my data.
Is there something wrong with the hardware or the software?
