Alright I'm currently working on a Toshiba Satellite A305-S6857 Model # PSAG0U-02701V. It is using Windows Vista Home Premium. When it was brought to me it was freezing at boot up and saying that the windows was an unauthenticated version of windows. It would also give an occasional BSOD with error code 0x0000024. Alright I've ran CHKDSK to check the harddrive but it does not find a single error in the check. Also ran memory diagnostic on the HIREN boot cd it passes. So I got her recovery cd's and restored it to factory settings. It worked fine while I put some of her old documents back on it and her Webroot Antivirus. Well I call her and she shows up and I always like to check my work and show the customers. Unfortunately, when I boot it up it starts freezing when it boots up and start automatically running CHKDSK. Now I get an occasional BSOD with error code 0x000000F4. Any suggestions on what to do next?
