Hi:
I recently acquired an old ASUS TUSL2-C (PIII-Tualatin) motherboard but can't get it to POST - I've already pretty much everything that most PC experts would do (including clearing the CMOS), and even removed the memory. Normally I'm supposed to get an error from the case buzzer if I remove the memory, but unfortunately that doesn't happen. So is the motherboard dead?
I don't know, but I also tried an older ASUS P2B (PII) board and it didn't work either (tried the same procedure), so I had to rule out that there may be an issue with my power supply. I noticed that the power supply that I'm using (430 watt, ATX 2.2 spec) DOES NOT have the -5V wire (despite the fact that the power supply label claims to have a -5V rail capable of supplying 0.3A).
So my question - would this be hindering my board(s) from booting? As far as I recall, the -5V rail was used for ISA systems - make sense for my P2B board, but my TUSL2 doesn't have any ISA slots. I don't have any older power supplies (that contain the -5V wire) at my disposal so I need some answers before shelling out some more $.
Thanks in advance
