lately i have been having problems with my internet (it doesnt matter which browser i use because i have tried 3 internet explorer, google chrome and mozzila firefox) when i try to connect to some sites it comes up saying "this web page is not available" for example when i open google chrome it wont let me connect to google.com and as google has an intergrated search and web address bar it does the same thing.
i dont know how to fix this, which links perfectly to my corrupt files in windows 7, when i tried to play games like "ARMA 2" the sound wouldnt play, i checked my sound and program sound and it was not muted, so i then tried to update 'direct x' and showed me an error about the update not being trusted even though is downloaded it from microsofts site. i tried to run windows defender which stopped half way through because of an error and now says that it cant perform a scan anymore, i also tried to update windows defender which also stopped half way through aswell as when i tried to install norton or mcafee. I also tried to go on my computer and repair some microsoft components but that said that is doesn't trust the updater.
May I add that this all happend after my hard drive crashed and i had to pay £30 on a recovery disk from toshiba as windows 7 was pre-installed. i have also tried going on "CMD" and typing in commands like "regsvr32" and for some of the commands it would say could not complete the operation. hopefully someone can help me soon with minimal to near no cost because it is starting to annoy me alot. thankyou
