Do not buy an Inspiron 3455 The system is quite slow compared to my 7 yr old HP it is not much faster... So I decided I was spoiled by the SSD that I had installed in my HP and would follow suite and install an SSD in this system to improve performance. It can not be done! For 3 weeks I have tried and even from Dells Community forum there is no solution. There is a lot of information and a lot of people with the problem... No Solution. Even Crucial failed me on this one as having no solution. With 37 years of experience this is my first NO-Solution could be found. And, Dell support what a joke. This is a bug in their system and the only response I got was "we would request you to please contact our Dell paid support for assistance on 8777903355" So, I can pay Dell, for me to help them figure out what is wrong with their system. No, I'll eat the $600 and use this as a target. A little tannerite and my 30-06 could maybe make this unit useful. For a minute. This is a really bad system don't waste you money. No way I can imagine the 90% approval rating shown here.... No way!!

Hard drive crashed within a year. Now repaired, it still runs slow as molasses--both keyboard as well as access to internet. So tired of waiting as the spinner icon goes round and round and round. As soon as possible, this piece of junk will be replaced with a more dependable and faster desktop. My Kindle runs faster than this computer. Bottom line: run as fast as you can away from this model.

I purchased this computer for Christmas after doing a lot of research.. 2 weeks after the return policy expires I get a blue screen of death. I have taken it in to best buy who sends it to whoever they send it to get it back and I have lost my 6months of virus protection which is the only thing that was on the computer since I hadn't had a chance to mess with it much. 1 week after I get it home set back up and want to get on it to pay a bill.. Well you guessed it crashed again... Save your $700!!

We bought this all in one due to limited space and the need to fit something under a 16" cabinet. This was perfect for that. The "pros" is that it's very attractive, has decent sound, and is a good price. The "cons" are many. First off, it takes this PC forever to boot up. I can literally go make breakfast while it starts. I've disabled all but the most essential startup items, cleaned the registry and temporary files, run various malware and virus scans, etc. No change. On top of that, sometimes it decides to not turn on or wake up, and to fix that I need to unplug the PC, hold down the power button for 10 seconds, then try again. Sometimes it starts (painfully slowly), and sometimes it doesn't. I thought a solution might be to put in a SSD, but I tried several cloning programs and none could create a bootable copy of the OS. Doing research, this is a well documented problem. So, I just went out and bought a Asus AIO that runs rings around this PC. Even the internet speed test is telling (same connection, same location) the Dell gets a 25mbps download, while the Asus does 180mbps. It's just staggering how something with decent specs like this can be so painfully slow.

I have a very high speed internet wireless system in my house, but this must be the slowest computer on the planet. I'm not a computer geek who expects lightening speed, but this computer is much slower than my last one when on the internet just browsing. When you initially get online, the homepage takes almost 45 seconds just to load up. Almost that slow on every page you move to after that. If I could return this, I would.

I purchased this all in one on August 5, 2016. The screen resolution is cloudy, not very clear at all. Windows Edge freezes up A LOT, daily. I had to download Google Chrome because the Windows Edge browser is not reliable at all. Photos don't show very nice with the poor resolution. I wouldn't buy this again.

On my 3rd computer. 1computer problem w/dvd reader, 2 computer constantly lost Wi-Fi conection, 3 computer power button doesnt always engage and wont stay in sleep mode it would always shut down & slow, all in four months, last Dell I'll ever buy . Impressed with Best Buy they have been great!

This is the slowest machine I have ever owned. Constant errors, constant losing WiFi connection, constant rebooting and taking forever to install updates. Don’t go with a Dell! It looks pretty but doesn’t function!

This is my second Dell All in One. My windows 7 lasted 5 years hopefully this one will exceed that.

I am a student and thought this would be perfect for what I needed it for. Aesthetically, it is a beautiful desktop computer. Saves space, the huge screen is useful when I need to do split screen it, sounds are great, but apart from that, it is sooooo slow. I have only had it for 7 days, exactly today, and it has crashed twice. The typing response is horrible, the touch screen function is delayed. and pages take eons to load. I set up the Trend Micro protection it came with and I am sure, this computer is not protected still. I keep getting those spam messages and a random page will load. Anyways, I would not recommend this and will be returning it this weekend.

This computer is incredibly slow. I bought it to replace an 8 year old desktop, thinking an 8 year newer computer would be faster than the old one. WRONG!! This computer is the slowest computer I've been on in years. I regret not returning it in the 15 day period Best Buy allows returns, but I kept thinking if I adjusted different things the computer would work at a normal speed. It hasn't. My 10 year old laptop is faster than this thing. I would not recommend this computer to anyone. I thought Best Buy sold good technology. I am disappointed in both Dell and Best Buy.

I've only had it for 24 hours so far, but everything seems to be great up to this point.

My wife and I purchased this computer from Best Buy in December 2017. Upon first using it we really liked it quite a bit. However, within the first two weeks of ownership we had a slew of issues. We got the blue screen of death, crackly sound coming from the speakers, driver installation issues, etc. We then brought the computer back and Best Buy replaced it with another one no questions asked. However, within two weeks, we had issues where the speakers were emitting a horrible crackly sound when playing music or watching YouTube videos. This computer is junk according to our experiences. The problem (that I've now learned) with all-in-one computers is that if you have an issue with say the sound or the screen, etc. then the entire computer is no good. Best Buy gave us store credit for the second one and refused to give us a refund to our credit card which was our original method of payment. It's not our fault that these Dells are junk and because of this situation, I will no longer purchase products from Best Buy. I now have $600 of store credit I do not intend on using, thanks a lot Best Buy.

I have had this All-in-One for about a year and a half and have had multiple issues. For starters, it crashed with one of the routine Dell recommended system upgrades. Wi-Fi is painfully slow (this was not an internet service provider issue as all other devices in the home work fine). Finally, system performance in general is slow. For example, I don't think this type of system is designed for movie maker software, i.e. Pinnacle. Touch screen is a nice to have, not need to have.

So far love my ALL IN ONE system. Learning a lot!!

I’m very disappointed with this computer as it did not last as long as I expected it to. I expected it to last as long as my HP laptop that was use 75% more than the all in one. I bought this all and one as a backup for my household the same day I purchased my HP laptop. We all have laptops 2 HP and 2 Macs so it got use for web browsing and scanning documents on the printer that was hooked up to it. The all in one have a black screen whenever powered on or it immediately shut off at powered on. I’ve taken it to two different Bestbuy geek squad and I’m being told I need to purchase a new computer because the monitor can’t be replaced being that it’s an all in one. Had I known this could be an issue, I would had purchased a desktop version.

This system is very slow and and after a year of very very light use the hard drive crashed I have been a dell fan for years now I’m not so sure. This was a very expensive unit when first released I am very unhappy lost all data

I bought this computer hesitantly as I'm not a fan of Dell or the all-in-one design. I should have listened to my intuition. This thing is a massive piece of junk. Right out of the box it took FOREVER to boot up which I figured to be normal. Once it was started it wouldn't open anything. It took several minutes to open Microsoft Edge alone and then wouldn't let me click on anything. It wouldn't let me download any apps or even click on them for that matter. I did try to download Google Chrome and it said the estimated time to download was 6 hours and the bar wasn't even moving. So after 3 hours of literally not getting anywhere with it I boxed it up and took it back. I exchanged it for a Lenovo which ran like a dream. Do NOT buy this computer. It has all the specs to be great but it is not.

keyboard and mouse don't work..........................

I am really disappointed in Dell. This computer is in my kitchen so it doesn’t see a lot of use but the screen went out after 14 months. I expected a little bit more?? I have always been an advocate for Dell because I use them at work but now I am in a position were it is cheaper to replace then repair. My expectations for a computer to work is only about 3 years since I so upgrade in about that time so I think it’s time to try something else.
