I don't know what is going on with my pc, it randomly restarted while I was attempting to check my email and upon said restart I got my first bsod. Now it always goes to bsod when I try to boot it. Safe mode either gets hung up on crcdisc.sys or loads and then crashes with the same bsod within a minute or so. The bsod I am getting says, ci.dll page fault in nonpaged area stop: 0x00000050 ci.dll - address collecting data for crash dump... I'm running vista ultimate x64 my mb is a gigabyte ga-ep45-ud3p I have a sapphire ati radeon 4870 and 2 sticks of ocz reaper ram (2 gigs each) a ucp 700w power supply and western digital 6400 aaks hard drive I've tried booting into ubuntu from a usb stick, that doesnt work either. I was able to use ubuntu to run memtest and my ram passed with no errors. I'm pretty sure this must be a hardware problem, I have not recently downloaded any programs, udpated drivers or anything like that. Any advice on this is much much much appreciated as I take online classes, the semester just started and I loathe this laptop I am using. Oh and I cleared the cmos and flashed the bios as well.
