Have you considered just having a new drive installed if everything else is working? Not a very difficult item to replace. It being an all in one makes it a tighter space and maybe not a do it yourself project but an easy fix for a shop. Then the operating system can be reinstalled. You should have a copy or at least the license number off your computer to allow the OS to be legally reinstalled from a disc.

I agree that replacing the hard drive is a good, low cost option. But considering that it is 5 years old, the remaining electronics may have 1000s of hours on those, therefore, a complete replacement may be best. If it has low on-time, say less than 10 hr per week, a hard drive replacement is good; If it was on for many hours per week, then I'd advise complete replacement. Power supplies and the rechargeable 'keep alive' battery do have limited lives.

The company I worked for replaced their engineer's desktop computers every three years. Sometimes, the case was re-used, but most often it was a completely new computer.

The brands I would look at that have all in one options are HP, Lenovo, Asus, MSI and of course Apple if you want to go there.

It depends on how much you want to spend, if you want touchscreen technology, which OS, there are now Chromebook options too, and you might consider looking at the new portable desktops not portable as a laptop but considered as portables.

I would still have the hard drive replaced in the other one personally. Home computers see much less heavy use than office units.

Thank you all for your replies. I have a computer techy person who lives in our community and he told me he could put in a used hard drive or a new one. I have decided to get a new comp and this time maybe not an all in one. I guess they are much more difficult to take apart and fix. Anyway....he suggested the same brands of comps to consider...except the Lenovo which he says it has been found to have some type of spyware in it? Not sure what he meant, but looking at HP, Asus, or maybe another Dell. Thanks again!

Oh....I forgot to say I need a large monitor. Not because I can't see, but I got so used to it! I am looking at 23".
Right now I am on my husbands laptop and can't stand the small screen, lol.

I have a HP all-in-one and really like it. Can't remember how old it is but at least 3 years, and I got it on sale because it still had Windows 7 and that was what I wanted. :)

I have an HP desktop with a 25" HP monitor, I personally have been very happy with all of the HP computers I have had. I don't think he is correct about Lenovo, that's a major brand they took over IBM. They sell a lot of computers. So I would not let that deter you.

My husband is an IT guy (who is a Dell Employee) as is my SIL, they always lean towards HP. I have a Levano Laptop for work and they are "ok" but a little flimsy IMHO.

Lenovo is a Chinese company that bought IBM's PC business what must be 10 years ago. I haven't looked at PCs in the market lately, but at one time there remained a semblance of two product lines, PCs and laptops (ThinkPad line) of IBM derivation, and others coming from Lenovo's legacy business. Both were good but the IBM derivative ThinkPad models have long been innovative and highly rated.

I personally don't think much of Dell or HP products, I think you'd do better with some of the others mentioned, including Lenovo. I've bought maybe a half dozen Lenovo products over the last 10 years (for different users in my family) and all have been terrific, so I guess that brand is my own preference.

(Edit to say - Lenovo also now owns Motorola Mobility, developer and manufacturer of Motorola Android phones. Lenovo bought this business from Google last year.)

You're right, jasdip. All new PCs come with pre-loaded promotional material. Because the market has become more price than quality driven, it's a way for the PC manufacturers to earn a slightly higher margin than the hardware sales provide.

The story I'd heard was that in striking what seemed like a normal deal for the promotion, the Superfish provider had misrepresented to Lenovo how the software would behave. Once the buyer noise became loud enough, the deal was cancelled and Lenovo provided guidance on how it could be removed. No company would risk tarnishing its reputation among customers by doing something so unacceptable in a promotion that that alone could hinder sales.
