I had a b450 Gigabyte for the last ~3 years until I tinkered in the BIOS with CSM/Secure Boot to see if my CPU/MB was new enough to meet Windows 11 requirements. Suffice to say, I bricked it just by trying to activate Secure Boot (no video signal, with any video card)! The first few times I could remove the CMOS battery, reset the BIOS, and it'd work again, but after a handful of tries, no dice...
A friend recommended Asus since I decided to upgrade everything (new MB, CPU, 32GB RAM total, new 1TB SSD, etc) and I wound up saving my Windows 7 partition/drive which could finally boot again (previously was lost to blue screen crash no matter what I tried)!!! I was really depressed I'd have to rebuild that desktop again, but enough persistence, money, trips to 2 MicroCenters paid off thankfully ($600).
So far so good, and quite the learning experience.
1) I'll never buy another Gigabyte MB again.
2) I'll never use the Microsoft Win10 Backup/Restore! What a false sense of security! I had a 2021 full system backup, but no matter what I did to restore, it'd give me a new error (i.e. "target disk too small to restore," so I buy a 2 TB HDD, then it'd say "element not found")
3) Make sure your video card is pressed firmly into the motherboard! The new ASUS MB has 4 LED lights to help you troubleshoot: RAM, VGA, CPU, BOOT. It'd get stuck at VGA I noticed, so I tried my old video card, then the lights made progress, green on BOOT, so I got a video signal!! When I tried the main video card again, I made sure to force it in well, and now it worked.
My first PC was Window 95, a Pentium 200Mhz MMX with integrated graphics, there's something to be said about that I guess instead of relying on a 3rd party expansion card for video output. I thought about switching to Intel since I've been with AMD since 2006, but everybody tells me Intel is lagging behind, so I stayed with AM4, etc.
Anyway, that's my quick story on why I'll stick with Asus! I really thought I lost that Win7 partition but it booted right up on the new MB once I took care of the video card problem.
