As the title says, I recently got a PCChips M577 w/ a Cyrix MII-333GP that exhibits the following symptoms:
- connecting an ATX PSU results in the board not turning on if I short the SUS-SW pins on the front panel (these act as the PW_ON pins too.)
- connecting an AT PSU will result in the board turning on, but after that, nothing happens. CPU does heat up normally which means I do have v_core
- will not beep regardless if I have RAM or not, same goes if I don't have a GPU plugged in.
What I have done:
- measured all surounding caps of the CPU - I get 2.9v, which is the voltage for MII-333GP and P233MMX (currently have a P 233MMX in place of the Cyrix)
- have recapped the mobo, thinking that the original caps were long gone - used Rubycons in place of G-Luxons
- tried any RAM and GPU combo I could think of
Any help on what should I try next?
