Thanks ... I checked the current rating on the 5v line of the new PSU and it's the same as the old PSU. I just pulled the RAM and I see that one module is a crucial pc3200 512 ddr (I think 400MHz) and the other is a crucial (I think pc2700) 512 ddr 333MHz. I think I have mis-matched RAM?

Thanks for the replies! I checked the temperature using a Asus utility that came on the CD when this board was purchased. All the temperatures are within threshold ... assuming the software utility is accurate. Thanks for the explanation on the multiplier * external frequency = speed. I did not know …

Hello ... I have an ASUS A7V333-X motherboard with a AMD Athlon XP 2800+ 333FSB, 512KB (2.083GHz) CPU installed. The AwardBIOS version is 1003. The BIOS is confusing me. I believe the BIOS CPU Speed should be 2.083GHz, CPU Frequency Multiple 12.5x, CPU External Frequency (MHz) 166/333, Memory …

Just wanted to thank everyone for their assistance. I ended up buying the suggested Startech PSU ... plugged it into this older ASUS motherboard ... and all seems to be OK. The Startech PSU is very quiet ... compared to the original PSU that came with this board (I remember it used to be loud!). …

Typically a server -- at least one in production, at a business where somebody gives a crap about IT -- will have a service contract. When the PSU fails, you call Dell / HP / IBM / Cisco and say "I lost a PSU, please have another here by EOB today." Then you go to lunch, and by the time you get …

OK ... thanks for the info. and reply. And the link. I had no idea PSU's could be so expensive. But I get that the PSU is a such a critical part of the computer. I remember replacing a server PSU back in the day. What a hectic day that was ... trying to find a replacement and install it within a …

OK ... thank you for the replies and assistance. I think I'm inclined to just replace the PSU. One last question ... this PSU/mobo have 20 pin connectors. I believe ATX PSU's are now standard 24 pin. So my main criteria for buying a new or used PSU would be to find one that is a ATX 20 pin 350W PSU …

Thanks for the quick reply Nvm1. What would normally cause PSU caps to blow like that? And/or what else might I check to understand WHY they blew ... before I go to the trouble of buying replacement caps to install myself? Or do PSU caps commonly fail in computer PSU's because the original caps were …

Hello ... while I wait for some jumper wire I just ordered ... I thought I’d start another project. I have a power supply unit (PSU) that when I turn on the PSU power switch ... the PSU fan momentary spins (with no noise .. it spins so briefly) and then stops spinning. This is when the PSU is not …

Thanks Tiido ... so literally run a wire from the negative battery terminal to your red dot? Sorry ... I may be over my head with this project :-) Some of the jumper wires I've seen are soldered to the underside of the motherboard. But locating traces from one side of the board to the other I find …

OK ... I checked the diode and it looks to be OK (thanks Tiido!). But I don't see how I can repair the trace.

Thanks for all the replies! The negative lead trace is the one that looks bad to me (darkened around the trace with some bright metal showing within trace). So that bad trace looks like it terminates under where the battery goes. The positive lead trace goes to D5 which I believe I mistakenly called …
