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
CPU
Intel Core 2 Duo E6300 @ 1.86GHz 46 °C
Conroe 65nm Technology
RAM
2.0GB Single-Channel DDR2 @ 333MHz (5-5-5-15)
Motherboard
http://www.abit.com.tw/ FP-IN9 SLI(C55-MCP51) (Socket 775)
Graphics
SyncMaster @ 1680x1050
320MB GeForce 8800 GTS (BFG Tech) 53 °C
Hard Drives
156GB Seagate ST316081 2AS SCSI Disk Device (SCSI)
Optical Drives
PHILIPS DVD8801 ATA Device
Audio
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.

Does your motherboard support that CPU?

Jumping in to see if I can assist here.

I have downloaded the manual to this motherboard and have researched what the board supports for a CPU.

Below is information from your motherboard manual.

CPU
• Designed for Intel LGA775 processor
with 1066MHz FSB
• Support Intel Core 2 Extreme, Core 2
Quad, Core 2 Duo, Pentium D, Pentium
Dual Core, and Pentium 4 Processor

Chipset
• NB: NVIDIA nForce 650i SLI
• SB: NVIDIA nForce 430 SLI MCP

Memory
• 4x 240-pin DIMM slots support
maximum memory capacity up to 32GB
• Supports Dual Channel DDR2 800
Un-buffered Non-ECC memory

If this link is willing to link correctly, this URL brings us to a downloadable zip file containing the pdf version of the owners manual.

http://www.abit.com.tw/page/en/download/do...KET_TYPE=LGA775

On page 2-1 of this manual is your BIOS setup utility user guide.

Please check that page for the BIOS setup.

Excerpt from the manual.

CPU Operating Speed
This item displays the CPU operating speed according to the type and speed of your CPU. Select
the [Linked] or [Unlinked] mode to enter the manual option.
Manual Option:
※ The wrong settings of the multiplier and external clock in certain
circumstances may cause CPU damage. Setting the working frequency higher
than the PCI chipset or processor specs, may cause abnormal memory module
functioning, system hangs, hard disk drive data lose, abnormal functioning of
the VGA card, or abnormal functioning with other add-on cards. Using
non-specification settings for your CPU is not the intention of this explanation.
These should be used for engineering testing, not for normal applications.
※ There will be no guaranty for the settings beyond specification. Any damage of
any component on this motherboard or peripherals resulting therein is not our
responsibility.

- FSB:Memory Ratio
This item selects the CPU-to-DRAM ratio.
Options: [Auto], [1:1], [5:4], [3:2], [Sync Mode].
- FSB (QDR)
This item selects the front side bus frequency.
※ Due to the specification limit of the CPU you installed, the speed you set over
its standard bus speed is supported, but not guaranteed.
- Estimated New FSB (QDR)
This item displays the estimated new front side bus frequency.
- Estimated New CPU Clock
This item displays the estimated new CPU processor speed.
- MEM (DDR2)
This item determines the DRAM frequency.
- Estimated DDR2 Data Rate
This item displays the estimated DRAM frequency.
- Multiplier Factor
This item displays the multiplier factor for the CPU you installed.
NB PCIe X16 Clock
This item determines the PCI Express slot frequency (slot PCIEXP1).
Voltages Control
This option allows you to switch between the default and user-defined voltages. Leave this
setting at default unless the current voltage setting cannot be detected or is not correct. The
option “User Define” enables you to select the following voltages manually.
- CPU Core Voltage
- DDR2 Voltage
- DDR2 REF Voltage
- CPU VTT Voltage
- NB Voltage


You could also try F6 for fail-safe defaults

Or F7 for optimized defaults to see if the BIOS will automatically work with your processor.

Please post back any questions you have if you are confused or please post back the results.

I do not know what BIOS update you used to flash your EPROM with, if you could post the revision that too would be helpful as well.
