Windows 7: Random BSOD

Random BSOD

Hi,
I reinstalled windows 7 in an old pc of mine that had the system corrupted.
(W7 32bit, 2gb ram, pentium 4 3Ghz).
After I did that, I keep having random BSODs.
I thought it was the ram, so i ran Memtest for several times, without having any problems.
I consider it being the HDD, so I ran crystaldiskinfo, and it said "at risk". cause "reallocated sectors" are at the worst value possible (100). This is kinda old so it may be.
I also tought there was a video card problem, since besides the BSODs, I would sometimes get a total screen freze, without being able to move the mouse or typing anything (I had this kind of problem in another PC and it was the videocard)...so I unplugged it and started using the built in one.
Still random BSODs though.
I'll attach the files your tool provided me with thanks for the help!

Since you got reallocated sectors, that should be a sign that HDD failure is a very real possibility. Post a screencapture image of CrystalDiskInfo.

Backup your data, then run this diagnostic:

Running the the long test via .exe made it go into loop.
So I used the DOS version (as raccomended), and I ran both short and long test; both passed.

New update: after the pc got freezed during the defrag yesterday, it didn't boot at all.
When I pressed the power button the fans started working, but nothing else, not even a BIOS load (nor a beep). I've both tried the on board vga and the vga card, but it just didn't boot. I've tried that several times but I was losing hope.
After some hours I tried again to boot it, and this time it did. Funny thing, after the boot the HDD was of 76GB and not 83GB as it should have! I've tried installing other stuff, and it got freezed again.
I think the hdd is definitely *ucked up, also because it started doing very bad noises (and from what I know, once an HDD starts doing those noises, it's kinda gone).

I just finished running the check disk on boot, and at the end it said "0KB in bad sectors".

Hi, thanks for the answer!
I've tried to run it twice via W7 with elevated prompt, but during the scan the screen gets black and i've to turn the pc off manually.
After I do that and I turn the pc on again, I get the message "BOOTMGR image is corrupt. The system cannot boot". I've tried booting in safe mode and it worked the 1st time.
Now's the 2nd time and the BIOS isn't booting. I guess the HDD is kinda gone.
