System: Asus a8n sli deluxe nvidia 6800gt 2 corsair xms 512mb ram 200gb western digital caviar SE 7200rpm 500 watt fotron power supply. 12V. So the computer has been running fine for about a year now. I went on vacation for a week and when I got back I keep on get this stop exception. STOP: 0x0000009C (0x00000004, 0x00000000, 0xb2000000, 0x00020151). This behavior occurs because your computer processor detected and reported an unrecoverable hardware error to Windows XP. To do this, the processor used the Machine Check Exception (MCE) feature of Pentium processors or the Machine Check Architecture (MCA) feature of some Pentium Pro processors. The following factors may cause this error message: • System bus errors • Memory errors that may include parity or Error Correction Code (ECC) problems • Cache errors in the processor or hardware • Translation Lookaside Buffers (TLB) errors in the processor • Other CPU-vendor specific detected hardware problems • Vendor-specific detected hardware problems Yadayadayada. The memory is fine, the temperature is fine, I cleaned out all the dust, reseated RAM, default settings (no overclocking), updated BIOS, and it still crashes. I included the last couple of minidumps, any help is appreciated thanks. The really weird thing is that it worked perfectly fine a week before and now it just randomly crashes.
