Hi folks...

Been trying to fix this laptop for a week now and I cant seem to pinpoint what the problem is at all..Here goes...

Its an advent 9415 UKT Support - Advent 9415 Laptop

Had vista installed when I got it. Wouldnt even turn on, power light would come on then cd drive would make access noise then HD would spin up and light would come on then HD would cut off and spin down. This continued in a loop for a while so I unplugged and pulled out the hd and tried to boot again. Same deal with the power off loop.

I pulled out the cmos battery and the ram thinking perhaps this might reset something. Bingo got it to boot again and I reformatted and installed windows 7. Logged on then froze again. Then rebooted got in again and all seemed well, installed chipset, video, sound, WLAN, LAN drivers. All good for 1 night!! Then the power off loop again!!

I ran spin-right boot disk and ran several tests on the HD without a single error. I then ran memtest 4.0 bootdisk and done several passes comprimising all tests over several hours with no errors!! (memtest stopped responding at one point and I had to reboot and rerun the test, but I got no errors from the program)

Motherboard??CPU??

If anybody could help it would be greatly appreciated!!

Cheers
