Hi, my sister's old laptop Toshiba (Can't remember what model but she bought it in 2012) has a problem where it will heat up quickly, has a long period of time to turn it on and bypass the boot-up sequence, and will never get into windows as it pops up a BSOD everytime i turned it on after the boot-up sequence.It has history before all that happens where my sister would complained that everytime she would use the web browser or do schoolwork it would turn off unexpectedly on a random occasion, overheating quickly.Thus, the problem just gotten worse from there to the point the problem ended up resulting the 1st problem I've mention earlier. Now the laptop is sitting in the storage room, untouched for 1 year plus now that she've bought a new Asus laptop. I just wanted to resurrect it from the dead because my dad told me that if it can be fixed he might wanted that laptop. Also, I've done a few diagnose but i suspected either the motherboard or the Harddrive? What are your suggestion guys?
