I'm having the biggest downswing with my gaming PC now. I had a really old CPU, the 7700k - so 7 years old. The 3080 has carried more than its weight so it hasn't been a problem but as CP2077 has been patched my FPS has decreased since the 1.5 release and with the last DLC it's been unbearable with CPU at 100% and GPU at 20-30% so it was time for an upgrade.
Landed on the AMD 7600X a new mobo and RAM. When I got the parts and started the heart surgery, I realized that I've thrown away the AMD brackets for my CPU cooler. It only cost like £5 on
amazon.co.uk but freight was £15 and then 25% tax on top of that, yay. Then I got the backets but there were no screws. So talked to my friend and he had lots at his work and they use Intel so I could get some from there. That in place, I continue the surgery only to discover that my PSU only has 1xCPU power outlet (it was also 7 years old) and AM5 cards needs 2. No worries, I could get a used one from my friends work so next day I get that and hook it up. Turn it on and *poff*. Also smoke from the mobo. Yay. Dissemble everything again, get the mobo out and it's fried on the underside.
The PSU is rarely faulty so I'm not sure if it was just an unlucky mobo but they usually test those before shipping so I'm not sure what's going on. Also the PSU was from the "tested - ok" pile from my friend's work so I test the "new" PSU with the old intel mobo and it loudly objected as well so it was the PSU. Sent the mobo back as RMA (although it was the PSU's fault) but forgot to remove the M.2 bootdisk that holds everything including all my TD files. Sent a mail and told them I want the M.2 back but I still have to wait for the RMA to processed and then returned to me. Yay.
Ordered a new mobo while waiting for the repair as well as a new PSU. Got the new mobo and PSU and hooked everything up again, powered it up and the self-test indicates "CPU fail or not detected" and "RAM fail or not detect". Great so both cpu and ram got fried as well. Yay.
Finally today I sent in cpu and ram for rma and I managed to use the same freightlabel as I used on the mobo so God knows what will happen to that package. Yay.
