STOP: 0x0000009c BSOD ( Ac 97 Realtek ? ) Hi guys and thanx for your time . I am getting these random BSOD screens 0x0000009c ( 0x00000004 0x8054D5F0 0xB2000000 0x00070F0F ), i noticed these started to happen POSSIBLY after a house power surge during a local storm , before that everything was running smoothly . I suspect it is the motherboard's audio card, AC 97 Realtek but I am not sure since I dont know how to read minidump files. I say so because when i do a 3D audio check m the system starts to lag and cough a bit Things I did : 1)Full chkdsk on primary C: . Clean. 2)New updated drivers for Ac 97 Realtek , according to motherboard model . Problem remained. 3) opened case and cleaned with air spray . Problem remained . 4) checked voltage and thermals with Everest and System Information for Windows (SIW) . All seem fine ( I think ) . I dont want to format yet or reinstall chipset , audio, video drivers yet before i got your opinion on the matter . I include 3 minidumps ( since i had overwrite checked and had none before ) and if u so want i can include any report from Everest or Hijack this .
