Hi, I have a HP Laptop dv1326ap pre-installed with XP Home. Week back my father switched it off normally & after that Windows is not booting up. On pressing the power button, the HP Logo comes up & then screen goes black. Tried starting windows to 'Last Known Good Configuration' by pressing F8, but no luck. Ironically, it did not come with any XP Disk & the restore disks have also not been created. Have tested the RAM as one of the doubts but its okay. Please assist.
