Steps taken to try and troubleshoot the errors. 1. Air compressed computer. 2. Reformatted 3. Bios flash corrupted Bios. Thankfully managed to upgrade it. 4. Disk checks and defrags. 5. Updated software, e.g. windows, virus, firewall etc. 6. Made sure memory was at its recommended 2.1 4-4-4-12 timings. Last time I tested each memory stick 1 at a time with memtest86. They were fine. Can test again if you think thats best. In the past I have had bug checks caused by Trend anti virus and my memory being under utilized by voltage. Any ideas on what else to try? Thanks for any feedback regarding this. Much appreciated.
