I went to the toilet for 5 minutes and when I came back, my computer was off so I tried restarting it and this happened. Its my custom built PC. Its been fine for a few months but a few weeks ago, It said before start up: SATA3G_6 Hard Disk:S.M.A.R.T. Status BAD, backup and replace. I dunno whats happened. The bluescreen lasts for less than a second so I hardly have time to read it, there are lots of 0's and F's in the error code though. I ran start up repair and this is what it gave me: Problem Event Signature: StartupRepairOffline Problem Signature 01: 0.0.0.0 Problem signature 02: 0.0.0.0 Problem Signature 03: unknown Problem Signature 04: 0 Problem Signature 05: unknown Problem Signature 06: 01 Problem Signature 07: unknown OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Some one please help me. I've not created a back up or a disk image file so It better not wipe the memory.
