Edit AGAIN:Seller shipped me a new hard drive for this machine, and it's doing the same thing as before. Freezing within a couple hours of startup. Either the CPU or the motherboard is bad.I realize it's been quite some time since my purchase, but when you sell a computer, your customers expect it to actually work.EDIT - After fewer than 4 days of use, I'm changing my review for now pending seller response. Turns out the hard drive is faulty. The machine has suffered near constant catastrophic freezing requiring hard reboots, and now won't boot past the BIOS screen. Hardware Diagnostics indicates Long DST failure.************Hey, I couldn't have built this machine for the money I spent here. Great value for the money, perfect machine to get my small son set up with educational programs and homeschooling. Everything you need (except speakers) comes in the box, plug & play ready.
