Good morning Cobra and welcome to CH
I do believe that Jason is getting you on the right road. In my past experiences that error you are getting ends up being a couple of different things. I am going to list these in the order of highest failure to least failure.
#1... PC's memory either 1 or multiple stick failure.
#2... Video card memory failure
#3... PCI card failure. This can be a modem, NIC, Sound card etc.
I would download and test your memory
http://www.memtest86.com/. Just download memtest and burn it to an ISO. Download memtest (
http://memtest.org/). Burn it to a cd using a dedicated .iso burning utility (
http://www.petri.co.il/how_to_write_iso_files_to_cd.htm), make sure the cd drive is at the top of the boot order in bios, then boot to the newly created cd and run the utility.
If the memory has even 1 error than the stick is no good. This can take hours to complete. If the memory pass then just like jason2074 stated I would remove all add-on cards to see if issue is gone.
Hope this helps you. Please let us know how you make out, Mike
