weird problems while booting Windows 7

[superhans123]

I have no clue what is going on with my computer...
Here is what's happening:
every morning I get up I start up my computer. I always get a bluescreen during boot process..sosomehow I was playing around with it and I figured out that when I turn the computer off (and therefore stop it from rebooting over and over again) and switch the two SATA cables that are connected to my 2.5" SATA drive, there won't be any problems on booting when I try to start it up again. this seems really random, because there is no right or wrong cable I am supposed to attach, seems like all I need to do is get on bluescreen on first boot, shut it down, switch the SATA cable connected to my harddrive and start it back up.
what's the point to that?! another weird point to this is: It only happens on the first boot of the day...I can reboot as much as I want after booting it in the morning, but once I go to bed and shut it down for the night, it won't come back on in the morning.
I don't even think it has anything to do with windows 7.

My hardware (in case this matters):

Intel Core i5-750
Western Digital Scorpio Blue 500GB SATA II 2,5"
Club 3D HD5750 Noiseless Edition 1024MB
Be Quiet! Pure Power 530 Watt (BQT L7)
Arctic Freezer Rev 2.0
ASUS P7P55D, ATX, DDR3 (Mainboard)
4GB G-Skill Ripjaws

I am going nuts on this, I simply don't get it..

The better way for that is that you should first analyze the problem and know where it comes from. For that the best way is to read the message that appears when the blue screen and analyze the file. Second major reason behind blue screen is incompatible RAM. That is also a major fault. You can swap your ram to a different slot and check back.

I think that it might be a power problem related to your Power Supply, so check the Volts or something by entering into BIOS, whether it is below the framerate or not. In my past, I also used to get similar kinda of problem, but after changing the Power Supply, all went right. Also it would be nice if you can post the blue screen error codes here, so that we can come to know about the problem. Thanks
