I had a couple BSODs in windows 7 that caused me to suspect a hardware failure. I did some testing including harddrive and RAM. I've determined that I have one bad stick of RAM. However, my Seagate 7200 drive came back with an error on a Long test using the proprietary Seatools test (must use to RMA with Seagate). That was before I eliminated the bad stick of RAM. Since then, testing hasn't produced an error. Logic would tell me that the RAM must have caused the single test error. However, I want to get some opinions from others who may have more experience. After all, last thing I need is a hard-drive failure three weeks from now.
