Slainte

Hi All....anudder newbie here. And like every other newbie, I'm looking for some help. Both my PC and laptop went down with a virus or malware. (unconfirmed):confused Ive tried the 8 step rebuild process with no luck, got some sucess retrieving lost data with Hirens boot CD on the PC... but it seems very slow.
Ive had to re-install xp on the dell inspiron laptop but now the screen goes wonky, like a fine wire mesh and freezes, tried altering colour/resolution etc but no luck. Is it a compatability error? any Major(or Minor):major Geeks available to help an unworthy biker?? BTW am I allowed to post our biker website here in Ireland??
