Hey, I'm new to this forum. I would really appreciate your help. I have a Sony Vaio and have Windows Vista installed. I have been running into problems every week or 2 months if I'm lucky. After couple weeks or months (if im lucky as i said) my computer goes all haywire. After I shut it down and try to restart, it never loads up past the Vista loading screen and goes into this loop. Or sometimes, it starts up but the light that indicates that your computer is processing/loading something is solid as if something is loading up. If i try to open any folder/programs/etc etc it takes about 10 seconds for something to simple to open and the light still stays solid as if its doing something and computer keeps making the loading/processing sound. As i explained earlier sometimes it goes into a loop at startup and displays some x000008300 ( i chose a random number) file is missing. I have been reinstalling the OS over and over sometimes in 2 months or even after 2-3 weeks. Its always the same reason and problem. Someone told me it cant be the harddrive because it wont last as long. Im really fed up with this. Its time consuming and really annoying having to start fresh and lose files/programs etc etc. I have Bitdefender 2010 installed as my Anti-virus and it doesnt detect any viruses and deletes the ones it does. I hope someone understands what i explained and knows whats going on and can be of some help. if anyone needs more clarification, i can clarify. i'd apprecaite the help. thx!!!
