I've been facing BSOD crashes for the past 3 months which occur mostly during browsing through flash content or pages with lots of data to load & sometimes even while the PC is in standby mode. Replacing memory modules & changing DIMM slots had provided some respite for a week or so, later on, the random BSODs started occurring more frequently. Apart from few instances where tdx.sys & ki1.sys have been displayed while BS memory dumping, most of the times no specific service has been identified. Attached the diagnostic ZIP file which includes screen shots of CPU-Z tabs & RAMMon HTML report. PC Config: MSI 890GXM-G65 mb, AMD Phenom II X2 550, 4GB(2x2GB) DDR3 1333Mhz RAM, Seagate 1TB Barracuda HDD, ATI HD4290 On-board graphic support. Kaspersky Internet Security Suite 11 & Malwarebytes Anti-Malware PRO 1.70 are the antivirus programs installed in my PC. Any help would be appreciated.
