BSOD constantly happening on my Acer Aspire Timeline X 5820TG

Hi

My computer has been getting the BSOD frequently (sometimes once a week, sometimes once a day, sometimes more frequently) since I bought it new over 4 years ago. I've sent it back to the manufacturer twice within the warrantee period with no improvement. I'm hoping someone with more technical expertise can assist me. I've copied problem details on one of the reports below. Please Help me someone!!!

This is Intel Rapid Storage Technology driver (IRST) please update it from Acer if they have a more current version for your machine.

This is Bit Defender Firewall and could be the cause of a lot of the problems. You could try updating it from http://www.bitdefender.com/Downloads , but personally, I would uninstall it.

Code:

dlkmd

This is WDDM KMD Loader - DisplayLink Core Software it can be updated
USB to video download: http://www.displaylink.com/support/downloads.php but other portions of the program need to be downloaded from the OEM. This seems to be a pretty specific program and should be downloaded from where ever you got it from originally.

Try these out and get back to us and see how it worked out.
