HELP I need a new desktop PC

[Jos7000]

Well everyone else has said something and so far you've lucked out hardware wise, so...
My Win 8.1 laptop that ran classic shell and behaved like a win 7 machine, died earlier this year.
After a period of catchup I opted for a micro form factor. Ryzen 7 processor, 32Gb RAM, 1TB SSD running preinstalled Win 11.
Firstly, Win 11 is a terrible OS and spends most of its time trying to sell you Microsoft products that you don't want or need. I then looked into Linux OS and installed Linux Mint. Because Microsoft is so alien to me, switching actually made sense. You can download it for free and run it on a USB to trial it.
As for your screen issues, it's quite possible that your screen is struggling with the connection, hence staying dark. Older screens can have issues with newer display ports on PCs. My LG TV has a HDMI port but wont display anything if my new PC is in the BIOS and I'm connected via HDMI, but if I connect to my TV using a HDMI to VGA lead, all of a sudden the BIOS displays.

Anyway, I bought my micro PC direct from China on Aliexpress for £230 brand new and it does anything I ask of it, it'll run any OS and hopefully I'm future proof for at least another decade.

Here's what I did.
I built the computer I'm running now back in 2019 from reasonably medium spec components at the time and although technology has moved on since then, to be honest there's little need to upgrade this computer other than maybe add an extra hard/SSD drive and increase the capacity of the two SSD disks ( 250 & 500 Gb) and the regular 1tb drive due to getting toward their maximum capacity.
I could further add another 16gb of RAM to the already 16GB in there but that would be about it.
The processor is a 6 core Ryzen 5 2600X and the Graphix card is a GTX 1060. It has a regular CD/DVD drive and a multi-card reader.
It's a general purpose machine used for everything including music playing and even though I may be getting on in age, I'm quite heavily into daily online virtual gaming (Battle Tanks of WW2) against opponents of all ages from all parts of the World and it stands up very well against opponents who I've no doubt will have all the latest gear.

The operating system is Windows 10 which is good for about another year before Microsoft stops updates so I will transition to Windows 11 in the coming months.
I have a relatively cheap full HD 25" Iiyama 1ms gaming monitor and a 7.1 surround sound system which is superb.
I often have 20-30 window tabs open at once and I only use Windows Defender to protect my computer and have never had any issues.
I have it all housed in a decent sized gaming case and several fans to keep everything cool and the Gigabyte Mobo is excellent.
The Hyper X Alloy Core keyboard and mouse are excellent value and issue free and perfect for gaming.

Boot up time is getting slower as more software is added and where it once only took 7 or 8 seconds to boot up fully, now it maybe takes 20 or so seconds to be fully up and running but it's hardly deal breaking and I can clean it up if I really wish it to run faster.

Before building my first computer back in 2011, I used to buy computers from the likes Compaq or HP which were OK but they were constructed so that they only just did their job and it was difficult to properly upgrade them in order for them to sell you another machine therefore I'd advise building one for oneself or getting someone who knows how to and then if you want to upgrade later it can be done. It's sort of future proofing.

Again one of the failings of such as Compaq or HP machines in fact most mass produced pre-built machines is that power supplies (PSU) are barely adequate so that once again those machines are difficult to upgrade without replacing the PSU and PSU failure is quite common on mass produced computers.
This is why using better quality components gives more stability and fewer break downs.
