Hey, I ran TDSSKiler and it detected no errors, however I then went on to run OCCT for 30 minutes, whilst it was testing it stopped and said there was an error in core 1. I then ran it again and it stopped again saying that there was an error in core 0. I have uploaded the graphs from both of these test for analysis. The minimum temperate ranged from about 26 - 29 degrees (Idle) and the maximum was ranged from 64 - 70 degrees.

Good news on the TDSSKiller.
What AV are you using?
Should run a full scan just to be sure.

Did you install the motherboard drivers from the CD or from the MSI site?
Check the MSI site for updated drivers: MSI B75MA-P45
Update all with newer dates.

Two OCCT errors blaming two different cores suggests it might be a settings issue, likely voltage.
D/L your motherboard manual: MSI B75MA-P45 manual
In your UEFI, post the Current CPU Core Voltage, Current DRAM Voltage.
Select the CPU Core Voltage and CPU-NB Voltage, tell us what the options are. Looking for a setting that will add to the voltage, so it's not locked in at a specified amount.

The voltage graphs aren't smooth like they should be, this could be due to the motherboard or PSU.
What model is the Corsair 600w PSU?

Those CPU temps are high, even with a stock CPU cooler.
Intel® Core™ i5-3550 Processor
TCASE 67.4°C add 5°C for the max core temps of 72.4°C.
Depending on your BIOS setting, it may be throttling down at these temps.
Check that the CPU cooler is tight, you may consider re-applying the thermal paste.

Do you have any MSI utilities installed?
Theses are known to cause instability, un-install them.

Which BIOS version do you have?
There is one dated 4 July '12 that states 'Improved memory compatibility'.

Im using Microsoft Security Essentials and have already ran a full scan without any errors coming up, and I installed the motherboard drivers from the cd that was given to me. I have not yet updated so will do that.

The PSU is a Corsair CX600w and I have found that the CPU Core Voltage is 1.0160v and the DRAM voltage is 1.5000v. Im not sure what you mean by CPU NB though as I cannot find it but the option for CPU voltage is on Auto but the options are +0.0200v, +0.0400v and +0.0600v.

I have checked the CPU cooler and all 4 screws have been clicked in place and do not move, however the thermal paste was already on the heatsink out of the box. Shall I still apply more thermal paste?

Regarding MSI features I do have some of the features that were on the disk such as supercharger for the usb slots, but I guess Ill be uninstalling them now. Also I tried to find the bios driver (1.2) but the only downloads are for 32bit.

Hi, I thought I would let my blue screen dumps build up before posting. Anyway there have been 6 more and Ive posted them for analysis.
Also I have updated the original post again to include all of these

Let us know when you have updated the drivers from the site linked above.

Did you download your motherboard manual from the link above?
If not, do it now.
CPU-NB Voltage is the voltage for your CPU Integrated Memory Controller, this can affect you system stability.

If the CPU cooler is tight then it's ok.
You can never add to existing thermal paste, you need to remove the old paste, clean the area and apply new thermal paste.

Remove all MSI utilities for testing.

Click this link for your BIOS site.
B75MA-P45 BIOS Update
BIOS allows your OS to boot with your hardware, It has nothing to do with 32/64 bit OS or drivers. Which means the same BIOS is for 32 and 64 bit OS.

Hi Dave, just thought Id let you know that I have updated the bios as you said, now I don't want to jinx it but so far it has not blue screened. However, it has only been a couple of hours and if it does, I will get back in touch. Thank you for the help so far.

I had hoped to have come back here, saying that it was fixed however, it has blue screened 3 times in the past half hour. However before that, the computer seemed to be running fine. I have uploaded the dumps. I did download a program called BTProx which whilst after setting up, blue screened with a "DE" error message. I then uninstalled this and then it came up twice with the classic "4E" blue screens I'm used to.
