Over the past week I've had five random blue screens that don't seem to have anything in common. For example, the latest one that I had today occured when I made a flash video on Tested fullscreen I got an instant blue screen and a strange sound coming through the speakers. I haven't had a chance to dust out my computer, reseat the ram, or run memtest86, and I'm unable to attach minidumps because they're over 200kb in size. If anyone has any ideas of what might be wrong I'll be very grateful. CPU: AMD Phenom II X4 955 at stock 3.2GHZ Motherboard: Asus M4A79XTD EVO Ram: Two sticks of 2GB Patriot DDR3 running at 1600Mhz GPU: Sapphire 5770 Vapor-x at stock clocks PSU: Sunbeam PSU-ECO750 OS: Windows 7 64-bit I'll run memtest tonight if I have a chance. Thanks for the help! Also, the computer was set to restart automatically on system failures so I changed that. If I encounter any more blue screens I'll be sure to post the error codes. Found the error code, it is 0xc000001d I also found an event called "BugCheck" with the message: "The computer has rebooted from a bugcheck. The bugcheck was: 0x0000003b (0x00000000c000001d, 0xfffff880044d417c, 0xfffff8800b37b040, 0x0000000000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 081710-52291-01."
