I run a Windows backup to an external drive or network drive, and then pick up a new drive along with an external enclosure. Then I pull the old drive and put it in the new enclosure, and install the new drive in its place. Then use MS's Media Creation Tool to create new installation media on a USB thumb drive, install the new motherboard and new drive, and install W11 on the new drive. Then restore from the backup made to the new drive/W11 installation.

Keep the old drive in the new enclosure (or old enclosure if you have one laying around) around for a bit until you're satisfied everything was successfully restored from the backup. The old drive in the enclosure can be connected to the computer if you feel like something was missed from the backup (nothing should be missing if your backup was successful), and search the old drive for the missing file.

Once you're happy you have everything, repurpose the old drive in the enclosure as a backup target for the new installation.

PCIe 4.0 x16 Slot for the GPU may improve performance but only slightly depending on the rest of your specs. Doesn't look like there's RGB headers on the board, so be aware of that if you need them.

I bought this for $80 from the previous Slickdeal and can confirm there are no RGB headers despite the description showing "Supports Addressable LED and RGB LED Strips". I ended up buying a fan bundle that included a fan controller [amazon.com] to get RGB effects. This controller is able to get PWM speed information from the motherboard's SYS_FAN header.

Personally, at this point, I would put the money toward a full platform upgrade. Yes it's a lot more money at once, but the upgrades will be much more meaningful compared to spending smaller amounts frequently for insignificant upgrades.

Yeah that's what I should do...
but if I'm gonna do all that I might as well save up for the 9600X bundle from microcenter [img]https://i.slickdeals.net/images/smilies/biggrin.gif[/img] the only thing I'd be missing with that is a new SSD and then I'll have two PC's
My only real complaint with my current system is that one of my RAM slots is messed up, when I first built it I would get BSOD's constantly and then it just stopped, it turned out windows had disabled my 2nd slot so I was only running on 8gb for like a year. I ended up upgrading to a single 16gb instead but it's just not enough™️

Short of physical damage to the RAM slot, I find that RAM sticks can be finicky - sometimes playing "musical chairs" with them in different slots and combinations can flush out whether it's the slot or the stick. I've personally never had a problem with a slot, only the RAM sticks themselves, but I also know someone who "brute forced" a RAM upgrade disregarding the notch, and had to have a motherboard overnighted to recover (a business PC).

Try booting in to the BIOS with a RAM stick installed in the "bad" slot and see if the BIOS(UEFI) sees it - Windows won't disable it, but if the BIOS doesn't see it, neither will Windows. Try a couple different sticks in the "bad" slot to isolate if it's the slot or the RAM.

Yeah, I tried swapping them, even got a different set (that's why this board is appealing, I have 4x8gb sitting on a shelf)
The worst part is that it's my #4 slot IIRC, so I can't load up all 3 of the other slots. I tried again recently to go back to 2, thinking maybe it was the memory controller on my old CPU that could have been causing issues but it won't even POST with 2 sticks installed anymore

Ugh - frustrating. I am trying to talk myself out of this board along with the 5500 CPU on sale for $62. ~$129 for a motherboard and CPU is pretty compelling. This motherboard has 2 NVMe slots, so an OS drive and a game storage/data drive - makes for a nice clean install with no SATA or power cables needed. I may be weakening...😆

It sounds good on paper, but the 9600X combo is $260 at microcenter and comes with DDR5, hard to beat
