I already cleaned everything. But, what about the fact that the machine only POST when it is cold? Regards, Ariel Thermal expansion or specs of some failing component change for worse when it gets warm and system doesn't work anymore. If cleaning didn't help, I'd also check the planar closely for …

A Period correct Enermax are built like a tank and would require capacitors to be changed only in rare cases I went to the vintage PSU route so that I don't need to think that much about the MB VRM or GPU and I can slap any board in the system if I want. I got Enermax EG365AX-VE(g) and slightly …

Sure, but it should POST anyway right? Even without the battery. Regards They should post without battery, but they throw 161 and 163 errors and you need to boot the system with setup/reference disk to update the configuration. This is every time you power on the system, if you don’t have battery. …

Goes a little bit offtopic, but I’m actually curious, how would you measure this kind of high voltage damper diode to find out if it is indeed genuine and what the stamping says? I’ve never had to do this, so I haven’t never needed to find information how. Oscilloscope, high voltage power supply …

[...] My recollection is that the first-gen Pentiums were just not that popular. The subsequent year's P54Cs were much better received... but even then, Pentiums remained quite expensive and a lot of people were still getting 486s... Indeed. The Socket 4 Pentiums were eye-wateringly expensive back …

there are socket A boards using 12V for cpu power, for example https://theretroweb.com/motherboards/s/msi-kt2-combo-l-ms-6764-v1 What I’ve gathered, it still varies how much those boards actually draw from 12V line for CPU. Many of them are still very heavy on 5V. In the end, I personally decided …
