It may be a number of things, including the disk controller. However, if you have one disk which is a good one (probably the new one) which has a complete copy of everything, then disconnect it from the computer and put it off to one side securely.
You can then experiment safely.
Problem is, it may be a number of things, including the power supply.
If I was you and I intended to buy a new machine anyway, and if I knew I had a complete set of everything safe, then I'd just live with it and keep using it until it blows. Hopefully you'll have a new machine by then, but if not you'll just have to go and buy one. At least you won't have lost anything.
Probably not a lot of point in complex problem solving on something that you don't care about for more than a few weeks.
