Windows 7: Constant and Random BSOD even after Reformat

Hello Guys, I'm getting BSODs even after I reformatted. It was the ntoskrnl.exe file that was giving me problems so I followed advice and just reformatted my computer. However the BSODs are still happening. Could someone help me please. I've attached my dmp files here.



Thanks in advance.

Welcome

I see no antivirus listed. Can you tell me what antivirus you're using?

I'll post suggestions after seeing your answer

Hello! Thanks for the reply. I am currently not using any anti-virus software yet.

Why not
Anyway, run this tool How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)? let me know if it finds anything

Hey, I've done the scan but it shows no errors.

Alright

Your Ralink RT2870 series USB802.11n Wireless Adapter Driver needs to be updated.
Try getting it from here Driver Reference Table

Run the system file checker to repair any damaged files within windows:
SFC /SCANNOW Command - System File Checker

Then run disk check:
Disk Check

Hard drive test both short and long with:
SeaTools for Windows

* Additional:

One of your dumps indicate memory corruption.

Check your ram for errors for 8 passes (overnight):
RAM - Test with Memtest86+

For the USBPORT.sys errors, go though the tutorial below for a possible fix:
USB Driver - General Fix for Problems

Hey, so I've done everything you ask me to do, all yielding no error messages. Except the ram test, which I did and now my windows can't load anymore . It also tells me it can't be repaired.

I did some checks and realized my BIOSTAR motherboard doesnt seem to support (at least they didn't list down in their list of rams) Crosair rams. Could that be a possible cause of my random BSOD?

My motherboard is the Biostar H61MLV and my rams at the Crosair 4gb DDR3 (x2)

Updated your network drivers?
Did you get any bsods?

Hey yes i did. I followed all the steps above. So, I just reformatted my computer, checked my hard disk for any bad sectors and It all was clean. Nothing wrong could be identified.

So currently with my recently formatted computer, I installed
1. google chrome
2. My Belkin Wireless Driver
3. My Nvidia latest driver (Clean install)
4. Turned on my driver verifier

Then, while transferring some files over to my external Hard disk for backup, a BSOD appeared again. So i installed Whocrashed and did a check. This was the result:

I'm really lost here, I have no idea what is causing this problem. It always seems to be a different driver that is causing problems.

So I am wondering if its my Ram that is causing an issue as my motherboard H61MLV does not list my Crosair 4Gb DDR3 rams in its supported rams list.
