I suddenly have many reboots. It appears to be electirical. It may not boot the first time but starts and runs for varying amounts of time before it gets a black screen and reboots. Often before it reboots, it creates an alarm on my APC backup ups 550 battery. The computer is 9 years old, 16 g ram, runs at a good 3.4 mhz, i7 and widows 10. If I know the component that’s causing the Whea_uncorrectable error,if it’s replaceable, I can do it my self and the cost is less than $50 I will keep it. But if not, I will dread spending money on a new PC, but I won’t have a choice. Any suggestions are appreciated. Thank you

If I had to offer a guess, you probably have a defective power supply. However, first thing to try is to access your power supply and thoroughly blow out all the dust and crap. And while you are at it, do the same for the rest of your internal desktop chassis. Also, remove your RAM, blow out the RAM slots, and reseat properly (snap-snap). Check all other electrical components as well for proper connections.
Once you're done with this, try the renowned PSU hair dryer trick. No, I kid you not: https://www.instructables.com/Fix-a-dead-power-supply-using-a-Hair-Dryer-Reflow/.
If the above fails to fix your issue, we are probably back to a faulty power supply.
[EDIT:] Lest I forget, check your motherboard for bulging/leaky capacitors, like this:
If this happens to be the case, you'll need to replace capacitors -which to be honest, is more trouble than it is worth in my opinion.
Anyway, according to https://partsurfer.hp.com/partsurfer?searchtext=E3W49AV, your power supply unit is a 600 watt unit, p/n: 633186-002. It so happens you can buy them fairly cheaply via EBay, for example: https://www.ebay.com/itm/354033498060?hash=item526e0a77cc%3Ag%3A05UAAOSwFNZiatJi&LH_BIN=1.
Hope this helps.
