PC dead, trying to troubleshoot, help if you can please.

[FishDog3]

OK, well my pc is dead.

Problems I was experiancing leading up to death:

1. All of a sudden pc started locking up during boot, usualy durring the windows is starting screen of win 2k pro.

2. Also, at the same time, the pc would reset, instead of shut down, when I shut it down through windows.

3. CPU temp was getting extreemly high through the boot, getting up to about 61c, than droping way down to like 36c once win 2k booted up and my cooling program came online.

4. I took out one of my 2, 256mb crucial pc2100 chips to see if it was the problem, and I was getting the memory problem beep code on one of them, so i left that one out and the other worked fine.

The final straw:

I turned it on, went through POST and first phase of booting up, just before it got to windows is starting screen, it shut off like i had pulled the plugout of the wall. I did not notice any "burning circuits" smells. But it would not go back on.

Current status:

If I unplug it from the wall, than plug it back in and hit the power button the HSF would twitch a little like it got a spike of power. But other than that nothing.

So currently I am thinking that either the PSU went or the MOBO is dead, I am not sure how to verify either of those thoughts, but I dont think it is the mem or the cpu because I would think that I would get a beep code if they were bad but the mobo/psu were ok.

I am currently taking everyhting out of the box, dusting it off, reseating it all, trying to make sure it is not grounded out. See if that helps.

So post any ideas, any at all.

Thanks.

Some mobo refuse to start if the they can't "see" a good working CPU fan. The CPU fan may be dead or have a loose connection.

Try emptying the PSU from any current in it (leave it unplug overnight) and that might fix your problem. I had the same prob and that fixed it.

PS
for the windows screen bit , that might be an IRQ conflict. Windows usually refuse to start if there is any.

JMO though

Try using the Basic 5 parts needed for a Computer to Run POST

1. Powersupply

2.Motherboard

3.CPU

4.Memory

5.Video card



Only have them 5 in you computer and boot it up it will run through POST if you have no problems then you know that all of thies 5 parts are good.
Then start adding 1 part at a time.

Good luck bro

What does it do when you use another fan?

[FishDog3]

is there a way for me to take a ATX PSU and disconnect it, than link some of the plugs in the headder that supplies power to to the MOBO so I could hook a fan up to it to q. see if the PSU fan fires up, 2. see if it is dead or not, 3. see if my HSF is dead or not.??

Also, pfter talking to several people, I am thinking that my PSU died, which sucks, but I would much rather fork over the cash for a PSU than a new MOBO, or CPU.

So if anyone has ideas on how to check if my PSU is truely dead, let me know.

Thanks

make the loop after it's powered "on"

The PSU has a wire called Power On. Usually the PSU has a stick showing each wire signal. At the PSU plug short the Power On to any ground using, say, a paper clip and the PSU fan should start. If it does them you will know there is something that prevents your mobo from activating the Power On signal. Using the started PSU try to make a 12V connection to the CPU fan. The stick at the PSU will say wich color is 12V. The ground is usually black.

Don't be afraid to blame the wall plug either. Dirty power kills. See if you can get her hooked up to a different power grid and see if the behavior continues.

How old is your house? I lived in one where the power was installed in 1921. Bad, bad wiring in a house next to a smelting plant (i.e. blast furnaces draining the power grid). I had to put my rig behind a surge protector with an UPS with Pure Power plugged into the surge.

They really need to start making surge protectors for coaxial cable. Or do they?

Make sure you try Krome's suggestion for jumpering the PSU first. That way you should quickly be able to either prove or eliminate the PSU as the problem. You could very well have burned up your CPU. You don't always get beep codes from the mobo when that is the case.

APC has some for cable modems.

Ok guys, I shoted out the power-on (green on my PSU) wire, and tried 2 diffrent power cords on several outlets, one of them using a "Monster surge protector/power noise filter" for home audio equipment that my 27" TV + reciever are using just fine. The result: when I had it all powered on and I shorted the "power-on" line the PSU fan made the same little twitch and nothing else happened.

My conclusion: PSU dead, getting another one.

So hopefully that is the only peoblem as it is the least expensive to fix for me. And thank you all for helping out, I would of been a lot more screwed if not for you guys.

Down with cheep ass PSU's!!

I have a Magnavox Surge Protector that I purchased w/ my system in 1998, it has coaxial, and telephone jack in/outs as well as the powerstrip... Anybody have info on the Magnavox Surge Protectors... I can't find the box/directions for mine.
