Thankyou in advanced!

We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

If you are overclocking STOP

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

Memory corruption possibly Related to Lachesis.sys Lachesis USB Optical Mouse Driver from Razer (Asia-Pacific) Pte Ltd. I would update it to current and see if you still crash.

If you do we can run tests on your memory.

Ok Ima give it a try and update you! Thanks a alot man. Really grateful.

Straight after updating without restarting i received a bsod but after restarting it seems to be no problem so far.

Related to Lachesis.sys Lachesis USB Optical Mouse Driver from Razer (Asia-Pacific) Pte Ltd. Yours is from 2007 and desperately needs updating.

I would also stop using avckf.sys Active Virus Control Kernel Filtering driver from BitDefender AVC as it can cause BSOD's on some systems.
