Hey guys, I've been getting alot of blue screens. My blue screens are usually caused by ntoskrnl.exe. Computer start-up time is also slowed down drastically. I tried to reinstall windows but it usually gives me a BSOD during the reinstall or saying that the Windows installation disk cannot be read with a error code 0x00000c5. I have ran memtest for 13 passes and got no errors. I hope you guys can help me out.
