The machine: HP Pavilion a465c / P4 3ghz-512mb ram(there's one problem!)-160gb hdd-Winxp Home Edition-NOT SURE WHAT SERVICE PACK
The INITIAL ISSUE: computer keeps going thru a REBOOT CYCLE after POST and just when it hits SPLASH SCREEN.Will not go into SAFE MODE. If selected it reboots there as well.
What i did FIRST: Ran a CHKDSK using Winxp Home cd(NOT ORIGINAL cd that came with pc).It found and fixed some issues but it didnt say WHICH. Tried to boot pc again.NO CHANGE.Same rebooting issue like before.
WHAT I DID NEXT: Did a REPAIR INSTALL using a cd i had(WINDOWS XP HOME EDITION SP3).I dont know if the person had this install on SP3 with all the latest updates.It MAY have just been on SP2 or earlier.Afterwards pc came up BUT it said it MUST BE ACTIVATED. OK and CANCEL only options.I hit OK.It came up to desktop but the desktop is BLANK and remained blank even after 20 minutes! It does the same thing in SAFE MODE.
WHAT CAN I TRY NEXT?
