Impotent I FORGET MY DRIVER CD AND I FORMET MY PC plz tell me what is proses of instoll drivers by net

AS FAR AS I KNOW YOU HAVE TO HAVE A FACTORY DISC. MANUFACTURES OF THE COMPUTERS USED TO SULPPLY THIS START-UP DISC WHEN YOU BOUGHT YOUR NEW COMPUTER(WINDOWS XP PROVIDED)THIS WAS TO RECOVER WINDOWS ONLY ... ALL YOUR C:/ FILES WILL BE ERASED. HINT: TO SAVE DOCUMENTS SEND THEM TO YOURSELF BY E-MAIL AND CREATE FILES IN YOUR MAIL BOX. IF YOUR COMPUTER EVER LOSSES C:FILES. ALL YOUR FILES WILL BE SAVED ON eg> AOL MAIL. THIS MAY TAKE 2-3 UPDATES FROM AOL TO COMPLETE. NOW YOU HAVE TO GO TO A RETAIL OUTLET AND PAY $40-60 TO HAVE THEM REPROGRAM YPUR COMPUTER. SP-2 CAN BE DOWNLOADED ON LINE ONLY ONCE YOU HAVE WINDOWS INSTALLED ( THEY ARE JUST SECURITY UPDATES.) iT IS A GOOD IDEA TO GO TO "RUN" AND TYPE IN CHKDISK. OR GO TO "SEARCH" AND CLICK ON ALL FILES AND TYPE IN CHKDISK. IF IT APPEARS IN THE LIST CLICK ON IT AND SELECT RUN. LIKE I SAID IF ALL ELSE FAILS ... ALL RETAIL OUTLETS HAVE WINDOWS XP AND VISTA. YOU EITHER HAVE TO PAY THEM TO RELOAD IT OR BUY IT. THEY WILL NOT GIVE YOU A COPY.... YOU HAVE TO BUY IT. ALL YOU NEED IS THE TOWER AND B E SAFE AND TAKE YOUR OWN KEYBOARD. A $15 KEYBOARD CAN GO BAD AND RENDER YOUR COMPUTER USELESS. WINDOWS HAS A ON SCREEN KEYBOARD OPTION UNDER "ACCESORIES AND THEN CLICK "ACCESSABILITTIES" CLICK ON "ON-SCREEN KEYBOARD.' GO TO WHERE YOU BOUGHT YOUR PC IF ITS LESS THAN THE WARRANTY TIME AND THEY WILL DO THIS FOR FREE. OTHERWISE YOU PAY. GOOD LUCK
