Good day, a friend has a weird problem. Her laptop is continuously booting. HDD checked; everything is fine. The machine came with Windows 7 Starter, but someone decided to upgrade to Win 7 Pro. Another techi says the motherboard needs to be replaced. When I opened up, I couldn't find any blown fuses or capacitors. There was fresh heat paste but a LOT of dust and grime on the fan. So much for work ethic.

I've transferred all her data to my external HDD and proceeded with a new install, hoping that Win 7 Starter would resolve the boot looping. Now here's the weird part: when the installation was finished, the Toshiba came on with an LG screen. And the OS disk is an original. When I restarted, the looping resumed. According to Speccy there is a Sandy Bridge motherboard but I couldn't get the exact model number before the machine reset itself.

Please advise.

What is the boot order set to? Reset the BIOS to defaults. Is it attempting to boot, then not going to a bootable device and restarting?
