Ive had the occasional blue screen for a while now. Event ID always suggests it's bad ram. Well they're starting to happen more often, so I checked again and sure enough the same error. But then i notice 3 from earlier in the day, which was about the same time I ran defrag: Event ID 7, bad sectors. So I run chkdsk. I knew I had 3kb in bad sectors, but now I have 24. WORD files are tending to give me corruption errors. Occasionally an application fails (like when I try to shut off the pc), or open tabs in my browser just shut off. The SMART data says it's ok, but the uncorrectable sector count and write error rate are iffy and they're getting worse.
