Hi, I got Windows Vista Business 64 bit edition. Been running it for like 2 months now and its been fine. However, now when I turn on my computer it doesn't get past the windows load screen. The bar just keeps going and going. I thought Windows might need to be repaired so I put the Vista disc, but it does the same thing when I boot from the DVD, it just stays at the load screen. Starting a couple weeks ago I got a SMART error on the POST. I backed up my data, but just kept using my computer anyway cause I didn't notice any problems with it. Even if my HDD is messed up now, I'd think that the Vista disc would at least get to the repair/installation screen. Please post any comments on what might be wrong, or how I can fix it. Thanks.
