troubleshoot support: New PC-Build hard reboots when CPU is under load
You're working on a PC setup that's showing instability. It seems issues could stem from the power supply, motherboard, CPU, or even the graphics card. The recent crashes during Windows installation and the problematic reboots suggest one of these components might be faulty. You've already tried different PSUs and found only one 8-pin connection worked, which hints at a possible power delivery issue. The fact that it only crashes under certain conditions points toward CPU or motherboard problems. To narrow things down, you could test each part individually—swap the PSU, check the motherboard connections, and monitor temperatures. If you can isolate one component, that would help you decide next steps.
Check both the CPU and motherboard for issues. If the problem persists despite a healthy PSU, focus on testing the CPU and motherboard components separately to identify the faulty part.
It might be related to RAM as well. Turn off XMP in the BIOS if it's active and test again. You can also lower the CPU clock speed to observe any changes—just set all cores down to the base frequency in BIOS. Consider setting a low power limit on the CPU within BIOS, aiming under 100 watts, to see if that helps. Reintroducing the 4070TI could help; running FurMark or another synthetic GPU load ensures it isn't due to PSU issues. Monitor temperatures closely—these CPUs tend to overheat and may have socket clamp design problems causing contact issues. If overheating is the concern, a contact frame or BCS is strongly advised.
I used the GPU with a furmark and it ran smoothly. The ram tested without xmp but crashes under stress. The oddest part is the CPU seems to work better when not cooled—performance and stability improve. During Windows install, it handled well at around 86°C. I’m wondering if you can run tests on individual cores separately. It makes me think there might be an issue with one core. I’ve taken apart the PC and plan to re-test with the core parts tomorrow, updating you on the results. If everything checks out, I’ll consider a return instead of repairing. I’m still unsure whether to send it back or have it repaired. There’s a return fee if it still functions after sending it back.
Socket problems can occur. The cooler can exert pressure that affects CPU contact quality. Always use a cooler when running it. A proper method for CPU cooking is recommended.
The performance drops consistently across multiple cores. I've restricted the CPU to 100 watts, keeping package power at 1 and setting DPDLs to 100 watts. Despite this, it stays cool under load. Other suggestions? Also notice crashes during Geekbench CPU tests.
Likely a faulty connection or weak power supply on the vintage board. Good to have resolved it.
