Hi Christine, been dredging my brain box - start again- If you have problems with pagefile that is a Virtual Memory - RAM function- you therefore have a faulty RAM chip, one installed wrong OR an incompatible chip? Hard drive bad sectors: are you able to check drive SMART status? If not, then for XP or Vista you need to ensure drives are ALL formatted for NTFS. As a physical check - try checking component dates - remember that most drives have a five year guarantee ( they should be dated) - to see if shop gave you all new parts or tried to palm you off. Power supply is unlikely to be source of the pagefile errors, but a blown/incompatible RAM chip is very likely to be your problem.
