PC may become unresponsive?
PC may become unresponsive?
Hello,
My computer is around four years old and has been stable until recently when it began freezing. A few weeks ago it froze and wouldn’t boot past POST. When I pressed the power button, fans spun, lights came on, but there was no keyboard or display, then it shut down repeatedly. I reset the CMOS a couple of times before it worked again.
Last week, the same issue occurred except resetting the CMOS didn’t help. I disconnected everything from the motherboard and it kept looping. Only after switching to a different power socket did it start working. I managed to reset my PC and reinstall Windows.
Now it runs for about 10–20 minutes before freezing consistently each time. Could you help identify which component might be faulty so I can address the problem? Thanks in advance.
My specifications:
ASROCK Z390 Phantom Gaming 4
Intel® Core i7-9700F | 4.7 GHZ | 8 cores
NVIDIA GEFORCE RTX 2070 SUPER 8GB GDDR6
16GB DDR4 3200 Mhz Memory (2x8GB | Dual Channel)
600W FSP / EVGA PSU
Replace the CMOS battery. A low or dead battery can lead to unexpected restarts and booting issues.
I would likely suspect the PSU first.
600/700w was standard a long time ago, and more recent models range from 650w to 750w...
The best way to confirm is to swap it with a reliable PSU that meets the required capacity.
Try borrowing one if possible to test.
If not, order a replacement from a store offering a solid return policy.
Be prepared for a 15% return charge if necessary.
Consider purchasing a 750/850w unit, which is suitable for future GPU upgrades or builds.
A high-quality replacement should come with at least a 7-year warranty.
Hello, your recent PSU change might be contributing to the issue. There could be other factors at play. Additionally, adjusting the SATA ports helped you get a boot, but you still didn't progress beyond the loading screen.
