Why is my comp not turning on?
I’ve been running a standard Acer machine with an i3 10th gen processor and no dedicated GPU. The Amazon listing shows a 2021 Acer Aspire XC-895 Desktop. Two days ago my system was extremely sluggish, struggling to run Val without noticeable lag. The following day it took ages to boot Windows, followed by a delay in processing passwords before freezing again. I looked into possible causes and changed the RAM slot, then tried restarting the PC. However, the fit was too tight, so I removed the CPU cooler to try a fix. I remembered that the cooler had thermal paste and I didn’t have any on my machine. After repositioning everything carefully, I put the cooler back in place. When I powered it up again, a high-pitched noise emerged and the system failed to respond at all. The HDMI cable and monitor worked fine with my MacBook. I found online that PSU coil whine could be the issue, especially near the CPU area, though it’s also possible the CPU itself was the culprit. Could the PSU be responsible for both the slow performance yesterday and the current failure? Let me know if you have more details. Thanks!
