Hello guys! I recently got 2 BSOD referring to Acpi.sys. I couldn't found out what were causing these BSOD's and I'm asking for Your support. Just before the BSOD appears, the PC is sluggish. My computer is a DELL PRECISION T5500, hex core processor XEON 5675, video card: Quadro 4000, 12GB RAM ECC, 1.5 TB HDD and Im running Windows 7-64 bit I have the latest drivers. Here's the link of the uploaded BSOD's. Minidump.rar If someone can detect the cause I'll be very grateful! Thank You very much!
