hi. i hope someone can help with this. various problems with my pc. i use windows xp. running slow. very often it totaly freezes and theres no response from anything i click on. sometimes it just switches itself off then on again. also i keep getting pop ups instead of web pages that i click on that i never used to get. i did virus check and some viruses are locked and cant be deleted. they are in system 32 folder, but when i open system 32 folder it is completely empty. also iv got a strange folder called bho_n2_log in 'my documents', and when i delete it it just keeps re appearing even after i empty recicle bin. when i start computer i get the message 'there is no disc in drive d, please insert a disk', then i get a message saying 'specified module could not be found', then i get another one that i cant remember. finally a couple of times my screen has turned blue and i got a message saying windows has to shut down. hope you can help.
