I just built a new computer for my inlaws and had several BSODs with different bccodes (1, 1a, a). I formatted and reinstalled the OS, updates, as well as clean installs of all recent drivers downloaded from the manufacturer websites. I have had several BSODs after this and I am worried that it may be related to the memory I have installed. I ran a full disk scan, as well as SeaTools short and long tests. These were all passed with no errors. Also, I have updated the bios to the most recent, reseated ram, unplugged/replugged all sata and power cables inside. Specs are as follows: Windows 7 Home Premium x64 CPU: AMD Phenom II 555 3.2Ghz Quad Core Motherboard: Asus M4A785-M onboard sound, video, wired lan Memory: G.Skill 4GB DDR2-800 (2x2gb) F2-6400CL5D-4GBNT HDD: Seagate Barracuda 320gb SATA2 Thank you in advance for any help provided!
