Machine shuts off after 1/2 a second

[MSgherzi]

This is continued from this thread:

Somehow now the machine only powers on for about 1/2 a second then shuts off. I tried taking off and re-applying the thermal compound on the processor, removing RAM, I/O Board, unplugging the cpu/cpu fan power, making sure all wires are snugly connected, and removing the HDD.

None of these have fixed the problem and the strange thing is that I've put the machine back together exactly the way I took it apart so nothing is missing or disconnected at all.

I can't test the psu since it's just an A/C adapter and not an actual unit like a desktop. However, I see that the led light on the mobo comes on and anything else in the outlet works fine.

I was thinking that the CPU is utilizing it's throttling technology but after unplugging the cpu that seems unlikely. I can't even see anything on the screen such as POST.

Any suggestions?

I also forgot to mention that it smelt like something burnt inside, specifically near the CPU.

... This must be a joke..

It's not a joke.

Also, if you can't contribute to this thread, please don't answer.

hey don't get offended, you have started a few threads recently that smell of .......... , you took apart a machine and screwed it up, you obviously have no idea how to deal with a virus infected image , and ......... (not to mention the networking thread) let's not continue.... don't get offended when people treat you like a big joke.

1. The thread had nothing to do with an image. I was trying to find a good "virtual machine." The image isn't even virus infected(as I stated that I cleaned up MOST of the malware) so I don't know what you're talking about.

2. The networking thread has nothing to do with this. I've already solved that issue permanently. But then, you'd know that if you actually took the time to ask instead of making speculations.

3. I took a machine apart and now it doesn't want to turn on. Could be a short, something fried, etc. Could happen to either one of us.

hey don't get offended, but before you go around shooting your mouth off, you should get the facts first.

Again, if you have nothing to contribute to this actual issue that I'm trying to get some feedback on, then kindly move along.

Sounds like a joke. Its like your answering your own question, but yet you still want input.

When you burn a pizza you dont look at the black cheese and smoke rolling off of it take a bite and say. Hmm,... Guys this pizza taste funny I wonder if that black stuff means its burnt!

Likewise I kindly shared my experience with you on WPA1 and WPA2 cracking. You let me know that you already know everything about WPA1 that "time" in cracking does not a factor, (even though I have first hand experience) and that my long post was a waste of your time. And even after you acknowledged that WPA 1 was acceptable form of security you continued to seek WPA2 solutions for your client which seemed screwy to me. But I declined to comment to each his own. (you want to save your client time and money, but yet invest in more unneeded technology)

I think people on to these forums catch these things, which is why you now double post your threads and now your re posting an unsolved issue. Sounds like you grounded or shorted something in a small case with no room probably popped a capacitor. etc.

This is a chat type forum its small, neat, and not all cluttered. A little bit of tact and patience goes a long way.

Just because I said I smelt it near the CPU doesn't mean I've officially solved the issue 100%, does it?

I'm not a hardware genius, so just because "I thought" it was coming from the CPU doesn't mean it was. I only re-posted this thread because the other thread was about something a little different I felt this was geared more toward a hardware forum, if not, then fine, sue me.

As far as you digging up almost 3 week old posts, then fine. You're the one, honda, that stated "Hello I dont know crap about networks." I feel that you also answered your own question. I stated that a 64 character random ASCII key cannot be broken, WPA1 or 2. Go ahead and show me and incident and I'll show you a flying pig. The fact that you even suggested MAC filtering also shows your lack of knowledge when it comes to networking, as does this post show my lack of knowledge in hardware. If we can come to understand that some on here are better in certain areas then others, then we can continue having a forum. If not, tell me what the point of these forums are?

I already figured out the problem with this PC not turning on. So thanks for nothing.

 

[abe]

it makes me happy to see you 2 getting at each other, just don't start throwing hot slices of cheese covered dough at each other.

 

[Bryce W]

Did you get beyond the video problems with it and this is a new problem? or are things just getting worse?

Beyond what the others have said and without looking into this any further. You could have toasted the CPU by not seating the heatsink correctly or something when you put it back together. That would explain a still working motherboard light but no post.

I have also seen machines power up then quickly shutdown when the 4 pin P4 connector isnt plugged in properly. I have also seen plugs getting hot and burning when they arent making proper contact such as this.

Again, without seeing the computer and spending time really researching this for you, I am just guessing at the moment.

@abe

That was clever. Must have taken all 3 brain cells to come up with. Good job!

Bryce,

This is a new problem. Hence the reason I moved it to the hardware forum.

It wasn't the heatsink as this problem took place before I took that apart.

Due to the responders, I don't feel that I need to contribute the solution that I found to this problem.

Thanks though, BW.

Gee, another one to add to my ignore list.

Even though you didn't like the responses here, why not tell the solution? Might be of use to someone else that comes along with the same problem. Seems to me that if one asks a question in these forums they should expect to be flamed. Just read through some of the forums, lots of people get flamed here you are not alone. I do have to say there is a wealth of knowledge here and this is a great forum, I just wish some of the flaming would stop.
I know it is frustrating to some when questions are asked that seem like a tech should know. Pizza tech comments start flying! I think they mean well and want to keep this forum for professionals in the business. No offense to you MSgherzi, I am not saying you are not a pro or in the business.

 

[hondablaster]

I would bet that the jumper was stuck in the clear CMOS or it was not inserted period. Or the 12 Volt Rail was loose or not installed.

Im just guessing. Just post the fix. Nobody flamed you that hard. It only makes it worse the next time you have a question.

I got criticized so I'm not telling what the problem was.

I tried remain silent and objective until that came up. If it got solved that quick I'll bet it was something pretty obvious. I've been following this from the beginning and maybe I should have said sooner as has been said 100 times on these forums. If you don't know how to take a particular machine apart, there is no shame in turning it over to someone who can. But there is shame in needlessly destroying someones personal property because you were trying to learn by trial and error with their equipment. Its a wonder if the machine will work properly in the future.

 

[MSgherzi]

I'll make you a deal. I will gladly fix your customers issues if you gladly pay my hourly consulting fee.

The bottom line here is you ask novice questions, we give you answers/opinions, and you straight up ignore them, and continue on with your fumbling and jumbling of a customers machine. The real big joke here is people like yourself get paid to do this stuff, and you come here for answers, disregard the answers, and get hell bent when someone tends to question your ability because of your inability to do even the most basic of tasks on your own.

One day you will fumble and jumble with the wrong persons equipment, and get in over your head, come here, and everyone will have you on ignore/not answer you, and you will be left in a mess. Hopefully the customer is smart enough to know their legal rights against your actions.

That's all I have to really say about that...

I challenge you to prove when I ever disregarded people's answers when they were actually legitimate and not something ridiculously stupid. It helps to read whats going on before you start opening your mouth and inserting your foot, pal.

And according to many of your threads, I can easily flame you for much fumbling and jumbling that you do as well. But I'll let enough of that be said. Again, opening a desktop case, which others also said looked tough according to the pictures I posted, and accidentally bumping something out of place and whatnot could have happened to anyone with such a small case, even you, mister so-called "professional."

@honda and anonymous mac, I don't care about the flaming. I feel that if you're not going to be respectful to me, then you will get the same treatment in return.

That being said, I'll post the solution, it was the 12V Rail, as honda suggested.

i challenge you to show me the threads where ACG fumbles and jumbles, and if he isn't "professional" then you aren't even an ape nevermind a human.

I don't have to prove anything to you. I don't have the time to go and look through posts several weeks back, like many of you do.

That being said, I'm finished here. If you'd like to continue responding like sheepole, then it'll only prove how childish you are. So go ahead.

the 12V Rail,

Thats a mistake that gets the most seasoned of PC builders/techs/gamers. Its like stalling your car because you forget to take off the handbrake.

Likewise Bryce made an article on that when he was at a gaming shop and had to school a bunch of gamers on basic repair essentials.

I agree. But, if you're like ACG, then you have to understand that you'd be completely wrong.

Was that the article where he was talking about the LAN party and the gamer had issues with his machine? Or am I thinking of something else?

Yes that one! Ive been guilty of taking apart a PC and forgetting about the 12v rail too. Not all PCs will shut off some will run and not do anything. I also have connected them and have had to connect them in and out several times because the PC is old. Im not sure if it cant make contact over time due to some very minor corrosion, dust, or just metal expansion.

Post like this are always good refreshers, even if we know something obvious, it does not mean that its not in the equation.
