Hi, need a bit of help with your Windows 10 setup. You have a GTX 1060, an i7-4770, 8GB RAM, 2 SSDs, and a 450W power supply. Your friend recently swapped the CPU from i3-4150 to i7-4770 and started experiencing random freezes. You don’t have time for extensive tests like MemTest86 or stress tests. In the system logs, it mentions crashes and low power supply issues. Could your PSU be insufficient for the i7-4770? If it was a RAM issue, you might see blue screens. I’m wondering what to check if the PSU isn’t enough for that CPU. After reinstalling Windows, if the problem persists, you could give your friend’s PSU a try for a few days. Or maybe the CPU itself is faulty, especially since you bought it secondhand from a long time ago.
Did you reset the CMOS before putting in the new CPU? Also, when you removed the CMOS battery and reinserted it, then placed the RAM in slot A2 B2 and the GPU, the PSU should suffice. I think there might be another issue. It might be that the old HDD is failing or the SSD isn’t working properly.
Ensure the 4 wire CPU connection to the motherboard is correct. The i7 has a higher TDP (84W) than the i3 (54W). Your PSU should function properly if it meets specifications and operates correctly.
I performed a CMOS reset but still experienced a freeze screen. Then I decided to reinstall the operating system again. As you mentioned, I received a new error about the HDD... but something else caught my attention. The Intel stock cooler appears to be poor quality, running at 2200APM without any noise. During the stress test, the CPU reached 99°C. With HDTune in quick mode, the HDD showed 50% very slow scanning, then it switched to fast scanning afterward. The HDD Reg SSDs worked fine. Still, I can't figure out why the HDD didn't produce errors under I3 but did with the I7 CPU. After unplugging the HDD, we checked again and it didn't crash again without it. We proceeded to order a new cooler—we selected the Arctic Freezer 7X, which was quite affordable (around $17). Here are a few screenshots for reference.
The critical issue occurs when I press the power button to shut down the PC, indicating the problem isn't with the PSU. The new cooler (Arctic Freezer 7x) significantly reduced the temperature to 60°C, which is excellent for its price. I’m now asking him to purchase second-hand RAM, giving him 16GB. After a random download of the Kingston health checker, please show me which main SSD (OS) has an available firmware update. The problem might be related to that update, or it could be something else. Since the i3 never caused issues before, I’m unsure how exactly it works—possibly the i7 is forcing the SSD to operate faster. After the update, there were no freeze screens, but the PC still didn’t restart properly. I’m too lazy to check again until next time when I visit him.
