Windows 7: Cant restore Win 7 without major problems!

Hello forum members!

Sorry if this is in the wrong place!

Sorry cant access System Info, I do know its running Win 7 HP-OEM with recovery disc, 4Gb Ram, ATI Radeon

My problem started with Internet Explorer needing to debug every time it was used, then Windows Explorer started doing same so it became very difficult to access things! Then things like Security centre was turned off, Event notification problems etc etc. I tried some things that were suggested for these problems eg running as Admin and changing settings, TDSS rootkiller, Malwarebytes to no avail.....so I tried recovery from d: no joy! I then tried booting from the disc - no joy, if anything its now worse...cant seem to update anything and it fails to find detection drivers!!

Any help appreciated, more info if I can provide it

thanks in advance

Mik
