Thanks for your reply TriggerFinger, have tried known good ram without any success also dont get any video to external monitor. I can hear the fan spinning and a slight bit of activity from the cdrom drive when i first turn laptop on. I have removed cdrom & hard drive in the hope of getting something to display on screen, still no luck. I have tried the steps you listed without any luck. On one boot up before the failure I recieved a resource conflict relating to Serial bus controller & pci mass storage device on motherboard, I was able to boot into the bios where I reset the bios defaults, would then get xp attempting to load but laptop would shut down fairly early into the boot process, I have just checked the fan and it is running normally, no dust or obstruction, everthing fine with all internal connections. ( I took precautions to protect against static damage), thanks again.
