start with the simple stuff. power down...open the case and check for any lose cables or ram..most times in shipping thing can get bounced a bit. if your tech i would reset the ram. if you have an older pc in the house you can use a usb memtest and make memtest boot usb stick. there also http://www.hiren.info/pages/bootcd
that has a lot of those tools and hard drive tools on it. a virus wont stop you from runing a restore cd most time it bad ram or a bad part. one other tick with bad ram is take out 1 stick of ram if the error stops swap ram..if it happens on the new stick of ram..you know one of the sticks are bad. also chekc that the mb used on the builkd you bought has all the bios updates and fixes for it.
