Hi everyone think this may be my first post here but anyway I recently built a pc and am having an odd issue anytime it gets bumped no matter how slight it shuts off and reboots .even walking past it can make it do this. Isuspect the psu but would like some more in put on it

now to the hardware 350w psu , ecs 671t-m v1.0 modo ,1gb crucial ddr2 667mhz , 80 gb western digital sata hdd , 320 gb wd ide hdd , ATI radeon x1300 pro pci-e vid card , sony dvd rw drive , 3.33ghz celeron d processor think thats about it if anymore infos needed let me know
 
Before replacing the CPU, I would open up the case and double check *every* connection inside the system, as well as making sure the power feed to the PSU is snug. It's possible something is just loose.
 
Wasnt planning to replace cpu was the psu i was talking about .

ive checked all connections numerous times tried different outlets power cords all with the same results i believe theres a bad solder in my psu everything else in was purchased new less than a month ago except for the cpu and cooling fan
 
could anyone recommend what wattage psu i should get im thinking 5-600w might be over kill just looking at future upgrades
 
Ok just try and diagnose this further i pulled out another 350w that i know has never had any issues and was running a very similar setup just fine for months and still have the same issue any kind of shock no matter how slight will make it shut off and restart does anyone have any other sugestions on what could be causing this

its realy driving me nuts i sneezed last night and just my body jarring from the sneeze near it restarted it. It did stop for about a day after leaning it on the side while it was running and wiggling all connections nothing happened till my finger ot hit by the cpu fan after the fan splitting my finger nail it wouldnt shut off for a day or 2 then it went right back

maybe irelavent info just stating what i know so far so maybe itll help me get some help
 
3 things come to mind here,
1 was the case previously used with a different mobo? If so, there is always the possibility that there is an unused standoff behind the motherboard that's making an intermittent short .
2 Are the screws on the mobo tight? Some of em need to ground.
3 I've seen some weird stuff happen with ecs (pcchips) mobos that just defied all logic.

yes to 1 and 2 im kinda leaning towards what you said in number 3 guess next thing to try is my other case ill get back with yall after i have a chance
 
Have you looked under the board itself to see if an extra stand off is toughing underneath? A slight tap or walking by would see shock or vibration to some degree where the board itself would like see an up and down movement where a lead could be touching a midsplaced standoff.

Anotther thing to consider would be a cold solder point on the board or connector somewhere(loose contact inside plug?) being intermittent with any shock or vibration.
 
This is the key idea im playing with now last night i layed it on my lap booted it up and started wiggling and tapping everything nothing happened so i believe it has to mobo related. guess my next step will be removing mobo and attempt to freshen up an solder points i can get to . If that dont work i believe yet another new mobo will be next step

On the last build when going to swap out a 480w supply for a 550w model nothing was seen at first giving me the impression of a bad supply. Upon seeing I had the suspicion to try unplugging the 12v cpu plug and then ever lightly replugging that back in. The problem turned out to be not the supply itself but simply a loose contact in the 4wire 12v plug. http://www.computerforum.com/80790-bad-board-simply-need-replug.html

Going in and trying to resolder connections may make more of a mess then using a multimeter to check voltages from the supply itself. Most meters also have a continuity tester built into them for touching leads barely inside a plug and any you can get at around the sockets on the board sometimes by tracing leads around for a short distance.
 
I may actualy be able to get this board replaced under warrenty (its only 3 months old but was purchased on ebay original sealed pckage) the power cord and psu im ruling out ive tried 2 diff psu's and 3 different cords all with the same result ive wiggled all wires inside while pc was running nothing happened also did the same with vid card. mem, cooling fans ,drives,even cmos battery nothing happens so im assuming its a problem with the mobo im gonna see about the warenty thing if i cant get it im just gonna buy a new board
 
It will probably turn out to be some cap on the board itself arching out seeing the system simply restart or shut off at that moment. Locating the exact source of the problem would likely mean using an oscilliscope to go over the entire board while power was applied.

For buying a board off of EBay oops! on the warranty part! That will depend more on just who the seller was there.
 
Even if i cant get the warrenty its not a huge deal only paid 32 bucks for it it was a spur of the moment decision .i was running a geforce 6100m with issues before hand .it would cut off to but was completely at random think the onboard gpu has over heating problems seems to be common with that board . I had 3.33ghz cpu layin around doin nothing so i just got what was cheap so i could use it
 
At this point you may want to consider moving out of that range to see something newer as the means of an upgrade. One old cpu went on one board seeing the mb toast there and then ruined a second one later when it was thought the first board alone was the problem. 1 cpu, 2 MBs all doa!
