ACK!! Please help, computer won't start!!!

post #1 of 16
Thread Starter 
I have an old HP Pavilion 503n that I use as a server, it's specs are P4 Northwood 2.5GHz, 1GB RAM, 80GB hard drive 7200rpm (ide), onboard graphics and sound, etc...

It had a total of two fans in it, the one on the CPU cooler and the one in the PSU. I just replaced them with very quiet fans. Now, when I try to power it on, both fans spin -- I get no error beeps, the hard drive spins up, and then it just shuts off. I can try again and again to power it on but it just will shut off with out any kind of error. I thought something might be overheating, but the CPU heatsink doesn't even get warm, and the air coming out of the power supply is room temperature. I've checked and triple checked to make sure all connections were tight and secure -- they all are.

I have not the slightest clue as to why it won't work. The only thing I can possibly think of, is that when I had to replace the fan in the PSU, the fan wires were directly soldered to the PSU board. So I cut them and put electrical tape around each end to insulate them. This was all done with the psu OFF, unplugged, disconnected from everything and discharged. I power the PSU fan now by routing it's cable out through the opening where all the cables come out, and I hook it up to a 4-pin molex connector with a 3-pin to 4-pin adapter. The only problem I could see here, is the PSU will not work if there is no "load" on it's internal fan wires. Would that even be possible? It's stock fan had a power draw of 0.23a on the 12v rail, would there be any way for me to put a dummy load on the internal fan wires?

Does anybody have any other ides what the heck is wrong here?

Well seeing as its so old, there isnt 20 pounds of dust in there that are caused it to overheat, is there?

I'm assuming theres only 1 stick of ram?

Theres really not much to test when all you have is a CPU and 1 stick of ram, and your motherboard (and a PSU and hard-drive of course). I'm assume that something bit the dust. :/

The fact that it spins up alittle makes me think that its not the PSU, the ram might of died, or the processor.

Are you positive that you didn't bump the heatsink to hard while replacing the fans? You could try reseating the heatsink and processor...

Its possible, but kind of rare, that if you had a shock built up in your hand, and you went to touch something (like your motherboard) it could fry your motherboard.

Ok, I just took the PSU out, and jumpered the black and green wires on the 20pin connector, and stripped the fan wires and hooked the fan directly up to the internal fan connection, and turned it on. The fan gave a little "jump", but didn't move, however I manually pushed the blades in their proper direction and it started going by itself (I think it was off because the it was not hot enough?). I measured the rails with a multimeter and the +12v rail was fine, the +5v rail was fine, the +3.3v rail was fine as well. What could be the problem? This system has no dust in it.

EDIT:
It uses two ram sticks, 512mb each, pc2100.

cut out one stick of RAM, and if i understand correctly you soldered in these fans nto your PSU? or are they simple three/ATX pins that you added... if you added, then remove and check, you you soldered/wired, then make sure you have the correct jumper setup and your solders are correct

The stock fan was soldered to the PSU board. I cut it, and put electrical tape around the cut wires to prevent a possible short. Originally, I had the new fan powered by running it's cable out the PSU through the hole where all the other wires come out, and using a 3-pin to 4-pin adapter to hok it up to a molex plug. With this setup, when I powered on the PC, the PSU fan came on full speed right away, but it shut off like I explained in the first post. Then I tried cutting the plug off the fan wires, and stripping them (the black and red ones, yellow left unstripped and out of the way). Then I took the electrical tape off the PSU fan wires, stripped them and hooked them up to the wires on the actual fan. This time when I power on the PC, the PSU fan gives a small "jerk" (CPU fan spins normal), and then it still shut off like it did before. So I took out the PSU, jumpered the green and black wires, plugged it in and turned it on. The fan gave the usual "jerK", and when I gave it a nudge it got going. I measured the rails with a multimeter (for voltage), and they were all fine. That is where I am now.

I will try pulling a RAM stick, but I highly doubt that is the issue, they are out of the way of anything I did and were never touched, and the RAM was bought maybe 3 years ago, Crucial. They are matched sticks.

did u try putting everything back as it was and trying ti boot (with no mods)
post #9 of 16
i seriously dont know what to tell you. everything you are doing to attempt to solve the problem is correct...

maybe you can try putting a big resistor on the power wire that you cut and the other side hooked to gnd that may prove whether or not its a 'load' problem....

also, just For my curiosity, why would you cut a PSU fan off its internal connector? more voltage? i thought PSU fans get 12V already anyway...and that any more voltage would ruin the motor.

I cut it off the PSU because I was installing a quieter fan. And the stock one was soldered to the board, no way to remove it without soldering or cutting. This is driving me nuts, I need to get this back up and running.

I just tried powering it all on again, same thing. CPU fan spins up like normal, hard drive spins up and I hear clicking, netword LED on the back of the ethernet port blinks, and then... it shuts off. Something that is a little odd, some times it stays on longer or shorter. Its not always the exact same time. Sometimes it shuts off after 5 seconds, sometimes after 7 or 10, but it is not consistent.
