I don't know much about the computer, since it is my sister's computer, but I can at least give you guys the basics. By the way, younger sister says there's no use in posting here, but I'm doing it anyway. So, my sister has a seagate HDD. Recently, a month or so ago, she started having problems with blue screens. The computer would be fine after for a few days, or even hours, until it happened again. It eventually devolved to where it'd ALWAYS want to perform a check disc. We allow it to do so, but a LOT of files would come up as corrupt. And even after that, the computer would still not work. We've done almost everything. We've done seatools multiple times, we've checked the RAM, and we even wiped the HDD to see if it were some kind of virus buried deep within the HDD. The last thing we're trying is using a spare power unit that has more wattage than the one she currently has. If that doesn't work, I'll post about the results here. But I would like instructions on what you guys need in case it doesn't work.
