** Please see edit at bottom**It is very, very possible that I just got a lemon. It's a risk one takes when you buy a refurbished computer, especially a potentially older model.For a little over six months I had an awesome running machine. As advertised. Speedy Gonzalez style.But there were signs. Sometimes when I powered down to restart it didn't want to boot back up and would throw a little fit, and it would take multiple attempts to get it to boot. It was that one little teeny, tiny nag in an otherwise perfect symbiosis between me and my beloved machine. Because unlike my laptop, this desktop didn't lag. It didn't freeze up on me mid program. Not that I was doing anything majorly taxing to begin with! But still. This beauty was a workhorse. It would run souch more than my laptop could dream of and with such ease.And then there was THAT morning three weeks ago. The morning I tried to boot it and ... nothing. Nothing.Six months.Outside of the limited warranty given to refurbished products, of course.Like I said. There had been signs. Had I heeded them, perhaps I'd have known there was some issue with this computer's power supply.Now six months later I am shopping again. I won't take a chance on another Dell. Research in forums shows me that this line is somewhat known for that issue and it is hit and miss.Instead, I'll take the loss. I'll keep what's left of it and gut it for parts since my daughter is unhappy with her sluggish laptop and since I'm looking into two computers, and the one I might be getting for myself might be semi-barebones without a hard drive, between the two this one might just be the perfect organ donor.That said. If you take the chance on this computer and experience power issues out of the box, I highly recommend contacting the seller right away. It's possible that you simply have what I had - a ticking time bomb. Because otherwise, this was an amazing computer worthy of a much higher rating. But with only six months of use, I can't give it more.For six months ... it was a five-star machine.Now. It's dead. Rest in peace.*EDIT TO ADD, July 3 2022:*I've changed the rating to four stars. I did indeed have an issue, however, it was a relatively easy fix. Turns out it was a dead power supply, I purchased a new one off of Amazon and installed it into this computer in the hopes that a $50ish part would breathe some life back into Speedy. And it did. However, I did wind up purchasing another computer for myself in that time frame that outpaces this one by miles (92 GB of RAM ... need I say more?) Anyway. I repurposed this one and gave it to my teenager, who has now been using it since April of this year and hasn't had a problem since except that the wifi dongle and our internet decided to stop communicating together. Problem solved by hardwiring to the router. But it's still a kind of buyer know what you're getting into the situation. Yes, this computer will be a speedy Gonzales, it will do all you ask of it, but beware that you ARE buying a used machine. One that isn't capable of upgrading to Windows 11. Not sure why, but it won't. This means that eventually, the lack of support for Windows 10 is going to leave it open to potential security risks. Know what you're buying. A good computer, but one that's got miles on it, that may need some replacement parts sooner than you think, but that with proper maintenance might last you for quite some time down the road.
