Futzinfind " I don't want to get off of the subject, but the power switch can be tested by powering on the computer then pulling the Power switch plug off of the motherboard. If it is a switch problem it should run fine until you shut it down. then you will have to plug the switch back into the Motherboard until it starts then pull it back off again. Its a temporary work around. Serving the Community one Computer at a time www.therushvillecomputerguy.com Please post a response to let us know whether our answer helped or not." Hi C Guy!I don't either sooo.. should we start a new thread?? LOL But since we're on the subject, Here's what happens:And this has happend to a lessor degree earlier. I hit (or press) the power button, earlier sometimes the fans would briefly come on then turn off, a few seconds would go by and they/all would startup just fine. now the fans just barely start to go and then shut down?? If I turn off the switch to the power supply for say 20 or 30 seconds (no LESS) then the fans would/will do the same... go on then turn off. If I press the switch again, nothing? only if I unplug or turn off the power supply for an extended period will the fans try to start. I thought I might take a switch out of one of the many older non-working computers I have and try one of those. After that and if that doesn't work, then i figure it could either be the power supply or the motherboard or???I sure hope it isn't in the motherboard!! A bad power supply would give me a good reason to jump up to a 750W or whatever. ____, it's like buying a new gun, I need a reason....NOT, hahaIf you have any thoughts on it I sure would appreciate hearing themYou're a good person and I think it is commendable that even though you are in the business to earn a living, you still manage to come here and help out us pO' folk.Thanks, a lot!P.S. I have checked all th e connections from the switches and LEDs via the manual and they are correct. 1 person needs an answerI do too

Ok, try this If you have the power supply cord unplugged and as soon as you plug the cord in the fans start to turn. A few seconds later the entire machine shuts down. Then you have to unplug and wait then plug it back in and the same thing happens again. Am I on the right track.

HiNo. not exactly. nothing happens until I press the "on" botton. That's when the fans start to turn. But the unplugging or turning off the power supply switch (at the back) just decreases the amount of time it takes to get the switch to turn on the fans for the short period that they do. If I wait, say all night (or maybe hours??) without turning off the power supply switch OR unplugging it, then the fans will react the same way. Note that the fans are the only indication I get that ANY power is happening when I press the switch.Also, a few, very few times, the switch HAS started the fans after a couple of tries but that was toward the start of all this go-no go stuff. That's what has me confused.The computer and motherboard were assembled in 2007 by the now defunk Awsome Computer Co in Salt Lake. But that shouldn't have any bearing on it other then the fact that it is not THAT old and the motherbord Co is MSI, which is from all i've seen and read is a pretty good company and the board has a lot of good features and should be upgradable for a couple more years.Well that's the scoop. I'm sure you know more then I do. Hope you can help and Thanks!

Did you say that you did try another power supply. You mentioned that you had old stuff laying around, try another power supply even if it is a lower wattage. You have to start somewhere given the fact that you don't have all the tools necessary. "If I wait, say all night (or maybe hours??) without turning off the power supply switch OR unplugging it, then the fans will react the same way. " What do you mean by this. They stay on all night if you don't touch anything after powering up the computer. If you are getting this then the POST is hanging somewhere. Are you getting any beeps at all. Count them if so and post back. If the fans are running and you are not getting any beeps it just sits there and runs the fans, then you may have a corrupt BIOS. Given that it never powers itself down until you do it yourself.Serving the Community one Computer at a time www.therushvillecomputerguy.com Please post a response to let us know whether our answer helped or not.

HI againFirst, first. No, I have left it disconnected since the startup failures started other then attempts to cure, then disconnect this one and try again. e.g. making sure all connection were correct. Keep in mind that this thing will not even get to POST. The fans only turn on for maybe one second then off. h*#l it might even be less then a second?I have a multi tester so maybe I'll disconnect everything and test whether or not I am getting any power at all to the respective plugs i.e. motherboard etc. +'s and -'s. This is a first but with the small plugs I hope my probe(s) are small enough! LOLLet me try that tomorrow and I'll let you knowThanks, AGAIN!Let me add. I am dumb on, well, quite a few things, however and I don't at all mean ANY disrespect but I have built up a few computers and built a couple from scratch. I know BIOS' and have flashed a few and set them up and ovrclocked etc etc. Just chatting sometimes makes one go "AH Ha!" and that I believe is what this is all about other then just plain not knowing anything about what CAN be done. I sure wish You lived in this neck-o-the-woods 'cause you seem a lot brighter then those I got this system from. You know the questions to ask.....and that is good.I'll get back tomorrow after I do a few tests

One question for you, Does the computer automatically startup when you plug the power cord in without you pushing the power button. After the computer is on it turns right back off and stays off until you pull the power plug and let the capacitors drain. After this you can plug the cord back in and repeat the above statement automatically starts when you plug the power cord in without you pushing the power button. After the computer is on it turns right back off and stays off Just trying to help Please answer for meServing the Community one Computer at a time www.therushvillecomputerguy.com Please post a response to let us know whether our answer helped or not.

No I have to push the button and the fans momentarily turn then they stop.

Ok, definately Power Supply or Mother board is the issue.Serving the Community one Computer at a time www.therushvillecomputerguy.com Please post a response to let us know whether our answer helped or not.

I took everything out. I even took out the motherboard and inspected it and cleaned it. I was going to do a bench test but got lazy and decided to put it all back together. First off I noticed the processor heatsink was ajar and thought this might have been from disassembly. Not. Apparently it was loose when all this happened. Anyway that's what I S.W.A.G.ed it. I got some heat sink paste and put it all together correctly. One note: Earlier I had changed (reduced) the max. temp of the processor, in the BIOS and reduced the tolerance spread. The processor down 2 degrees and the tolerance to + or- 1 degree. Guess what that did?(I think?) Since the heat sink was loose the processor shut the system off because it was outside the tolerance setting. I actually saved it all by making these settings and I didn't know it.I again shorted the "on sw." plugs( 20pin plug) from the power supply, then I tested each plug before I put it all together. All plugs tested ok and power supply kept running. Then I plugged the four prong back into the MOBO and turned it on again. Wa La! the processor fan kept running. So I turned it off and began to plug in one thing at a time each time turning the power supply off at its' switch. I eventually heard the old familiar single "beep" and new the system was trying to start.I hooked up the HDD, monitor, mouse and keyboard and good ole XP fired up!So, This just goes to show that we shouldn't give up until we have looked at everything. One little loose heat sink caused it all. I'm just glad the P4 processor had the capability to shutdown things down before it fried itself, or the motherboard.So here I am on that computer and all has been running great with no hitches for three days now.Thanks for all your help and interest. If not for that I probably could have spent a lot on who knows what, power supply? motherboard? At least it kept me looking/Futzing!Again, Thank YOUP.S. Then again...I could be just CHEAP! haha

I am glad that your system is up and going now.Serving the Community one Computer at a time www.therushvillecomputerguy.com Please post a response to let us know whether our answer helped or not.
