MBPro Win 7 x64 Errors

Hi, I have recently bought a MacBook Pro 2009 from a mate who sold it as faulty. The Apple store said it was a faulty Logic Board but couldn't say for certain what the problem was. Having experience with PCs I tried putting an old HDD in to test if it would work and it did. So I bought an SSD and installed Win 7 via Bootcamp.

Last night I upgraded OSX to 10.9.4 Mavericks which installed okay, then I installed the upgrade to 10.9.5 and left it running when I went to work. When I got home I found the Mac had frozen at the login screen with a spinning multi-coloured wheel in the top left corner but the machine was unresponsive so I had to hold the power button down for 4 seconds to turn it off. After I restarted the update installed (again) successfully.

In Win 7 here is the hardware specs of my Mac:

System Manufacturer Apple Inc.

System Model MacBookPro5,5

System Type x64-based PC

Processor Intel(R) Core(TM)2 Duo CPU P7550 @ 2.26GHz, 2261 Mhz, 2 Core(s), 2 Logical Processor(s)

BIOS Version/Date Apple Inc. MBP55.88Z.00AC.B03.0906151708, 15/06/2009

Having heard OSX was rock solid I booted into Win 7 x64 and looked through the event logs and found these 2 errors which seem to be hardware related:

could somebody point me in the right direction as to how to resolve these issues? My Machine has been upgraded to 8gb ddr3 1333mhz and a 240gb Kingston SSD 6Gbps. I think this version of the Mac only supports 1.5Gbps sata bus, I have downloaded a driver from apple to upgrade the EFI to install faster storage to the 3.0Gbps but they do not support it so I am unsure if installing it will be a good idea.

Thanks for reading.
