Bizzare Startup Problem

[splink82]

I have been using my computer for at least 6 months now, and have never run into the problem I ran into today.
This morning when I woke up, I unplugged everything from the back of my computer, flipped off the power switch (it was already off but I didn't want it starting on me), and proceeded to clean out the computer's insides with a can of duster.
After all this was done, and everything was plugged in and ready to go, I turned on my computer and it wouldn't boot in 64-bit.
Before I continue, it is good to know that my computer has a partitioned hard drive, and has options on boot-up to start in both 64 and 32 bit (Windows 7). My family primarily uses 32, while I use 64.
Anyway, I booted it up and chose 64. It went to the Loading Screen (the one with the windows logo) and after a few seconds of that, flashed a blue screen for a millisecond and then restarted. There are a few problems with this:
1) It doesn't even give me enough time to see what the error message is
2) I checked the BIOS and the boot order is correct
3) 64-bit was working fine yesterday, and I didn't download any malicious files.
4) I already tried Windows repair twice and it said that the problem could not be fixed

I could just access my important files from 32-bit, copy them, and reinstall 64-bit, but if possible I would rather take an easier way out (one that preferably does not involve me copying tons of files.)

Any help at all would be great. Thanks.

Yup. denis280 has it. I would also suggest reseating your cards.

Can you boot into safe mode? If you can, go into the system control panel, and go into the advanced tab, startup and recovery portion hit settings, and where it says system failure, click off Automatically Restart.

This will allow the blue screen to stay up without rebooting the system, and in some cases BSOD will say which driver (and then you know the component) that is failing. If its not listing which driver, then you should be able to google the stop message of the blue screen or the code "IRQ_NOT_LESS_OR_EQUAL" etc.

Edit - You can go into safe mode by hitting F8 i believe over and over right before the windows load screen appears.
