Bsod with new cpu

I just got a new cpu.. Core 2 Quad Processor Q8200 (bought brand new).

But keep getting a blue screen before windows loads.The main blue screen error is 'Clfs.sys'.

If i use my old processor it works fine.

Here are my specs..

Operating System
MS Windows 7 Ultimate 64-bit
Intel Core 2 Duo E6300 @ 1.86GHz 46 °C
Conroe 65nm Technology
2.0GB Single-Channel DDR2 @ 333MHz (5-5-5-15)
Motherboard FP-IN9 SLI(C55-MCP51) (Socket 775)
SyncMaster @ 1680x1050
320MB GeForce 8800 GTS (BFG Tech) 53 °C
Hard Drives
156GB Seagate ST316081 2AS SCSI Disk Device (SCSI)
Optical Drives
High Definition Audio Device
Power Supply

The bios has been flashed to support core 45nm.

The cpu is not overheating, and the cmos has been reset.

  1. I assume its a custom BIOS to support 45nm cpus?
  2. Also if I remember correctly some Nvidia chipsets for Socket 775 didn't like some 45nm or quad cores.
  3. Not sure your board supports that CPU. See here:

    I'm a bit confused as to what "Test" on that list means.
  4. I'll try a new motherboard, thanks.
