Constant Bluescreen Errors

Yep the flash drive was what I was wondering about and maybe it is corrupted and maybe you need to make a fresh ISO stick with this to eliminate that possibility.
Clean Reinstall - Factory OEM Windows 7 < just make sure to pick the right version for your activation code plus of course the language etc .

The hard drive it might be worth running a test over it using this
SeaTools for Windows | Seagate

and even a surface test with this Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition. (see pic)

Mind you might need access to another machine if the BSOD problem is there on that one.

I have already checked the flash drive issue and double checked and hence ruled it out.

I totally forgot to mention my SMPS makes a screeching noise before the whole system freezes. The screeching can last for 5-15 seconds. Sometimes it just goes on and on and I have to smack the cabinet part where the SMPS is located.
Probably should've mentioned this first

btw, here is the surface test result

This sounds very much like the PSU is on it's last legs Prince that screeching sound seems awfully like the sound of a capacitor about to destruct. I would have a close look at it but DO NOT try to take it apart and if you can have a virtual sniff around the smell of this happening is quite distinct as is any overheating on a circuit board too.

The PSU letting go would certainly produce some of the crashes you are getting. If I haven't mentioned it before run this and see what the volts are on the PSU.

HWiNFO, HWiNFO32/64 - Download < get the right bit version.

The pic I ma sending is on my laptop so it doesn't have the volts as such yours as a desktop will have the volts displayed.

Sounds like the whole machine needs a good overhaul Prince I don't know what CPU you have exactly but that temp is way out of whack and generally speaking 45C would be a good average.
