Yesterday my computer suddenly froze and then BSOD. After restarting, it was very slow and trying to open any programs or task manager took a couple of minutes. Few minutes later some programs report that they have stopped responding until Windows explorer stops responding and I get another BSOD. This happens if I boot windows normally. The first BSOD error code was 7a, the second was f4. After googling for a while and asking a couple of friends, it looked like it might be either HDD or memory. I ran memtest86 for 4 passes without any errors. I the ran HD Tune and it found a few damaged blocks. Here is what HD tune and CrystalDiskInfo say: http://imgur.com/FBvrOeC Is the disk going bad? It is still under warranty, so should I try to RMA it?
