Hello all, I have an older Gateway desktop that I am trying to use for my niece. It's been working great up, but tonight I tried reinstalling Windows. It froze at the "Windows will now check system settings" and I had to force a shutdown (holding power). When I rebooted, there was no VGA signal and the front power light was orange instead of green. The drives spin up and all fans work with the exception of the PSU fan. There are no audio beeps. It has a 3 pin connector that plugs into the motherboard, labeled Aux Power. If it's connected it will not spin, however, if I disconnect it from the mobo it appears to work fine. I tried different memory sticks, video card and power supply with same results. I know this is a vintage system by todays standard, but it has a ton of sentimental value for us. The motherboard is a Intel Fedora (Intel Solano 82815 chipset, 1Ghz PIII processor). Thanks in advance!

Could happen, that the reset switch is locked. Old pushbuttons do sometime get this problem.

"all fans work with the exception of the PSU fan" Do you mean the PowerSUpply fan or is it the CPU fan that does not spin? If you have tried with a known good powersupply then the next suspect is a failed CPU or faulty motherboard. I don't understand what you mean when you say "It has a 3 pin connector that plugs into the motherboard, labeled Aux Power. If it's connected it will not spin, however, if I disconnect it from the mobo it appears to work fine." What works fine when you disconnect it from the motherboard? Goin' Fishin' (Some day)

Thanks for the replies. I am sorry I wasn't very clear in my initial post. The following fans work: HSF/CPU, case fan and the fan on the video card. There is a three pin connector on this motherboard near the memory slots, marked on the motherboard as "aux power". It has a two-wire, purple and black wires coming from the PSU. If I disconnect the 3 pin wire, then the fan on my PSU runs fine. However, when I connect it back to the motherboard it will not even attempt to spin up? Maybe just a thermal feature? I have tried replacing with two working ATX power supplies, with the same results. Although neither of the two power supplies I tried had the 3 pin wire like the original above. Hopefully I made sense this time :) Thanks again!

The AUX power thing sounds like a proprietary "Gateway" feature. Since you get no beeps at all even when you use a different powersupply then I reiterate you are likely to have either a motherboard or CPU failure. It is up to you to decide whether it is worth investing any more time/money into something of that vintage. Goin' Fishin' (Some day)

Thank you for the follow up and info. I think a friend of mine has an older P3 I can try and if not that, I will be using the case decoratively I suppose. :) Thanks again!
