Sorry about your Mac! Attempt to first update your OS, as his may well be a bug. When you had your computer plugged to a monitor, did the flickering carry over to it? Or was it only on the Mac’s built-in display?
Well, the good news is OWC has a great customer service. So presumably, they could provide you with a replacement SSD— which would suck— but at the same time at least that’s a free solution. So I’d likely start there. It’s also possible that the Logic Board is failing. If that is the case, that sucks. But for now, I’d stick with contacting OWC. While I trust them, I’ve had my share of bad apples (pun intended) from them.
Given your computer’s age, I would guess that your SSD (Solid State Drive) is slowly but surely degrading in quality— which is to be expected. I highly recommend you first back up all your data. You may then attempt to inspect the SSD module: see if there are any signs of spills that might have taken place. If all seems fine, I’d recommend you replace the SSD. Good luck!
Hello, sorry to hear about your phone. Please attempt the following: https://help.ifixit.com/article/108-dfu-restore PLEASE NOTE that this procedure will erase all the data on your device if it works. In case you aren’t able to perform this process, or if it fails midway, you will likely need to replace the device, as this would be a motherboard issue. Good luck!
Hey! Sorry to hear about your Mac mini. So, as is with most Macs, the SD slot is part of the Logic Board. You optical drive also connect to the Logic Board, but is a modular part, meaning: it can be replaced somewhat easily, unlike the SD slot which is soldered to the board to my knowledge. Are your other ports working (USB/FireWire)? If both the SD and Optical drives not working it is likely a coincidence, but as a whole what they share in common is the Logic Board, which on your model Mac mini I would NOT recommend you replace because it isn’t very cost effective.
Hello! The three beeps likely signify a RAM issue. On your model Mac, the RAM is soldered the logic board. So, I would start by performing an NVRAM reset (Command-Option-P-R) and see if this fixes the issue. If not, its possible you will need to replace the logic board on your machine. Ensure that everything is properly seated, attempt to reset the NVRAM, and take it from there.
