What's happening?

[xcellerate]

So I just put my computer together and I press the power button, everything turns on for a second then turns off.

So I start unplugging stuff and the same thing happens, then I get it down to ram/mobo/processor and it does the same thing, and now it's just mobo/processor and it's still doing it. I then removed it out of the case and set it on one of the static-free bags and it still does it.

It's an MSI P35 Neo-F 775 R and INTEL Core 2 Duo E6400 2.13G LGA775. I've built maybe 8 computers and never had a problem before, and now I can't even get this one to post.

Anybody have any suggestions?

If your sure you''ve got it wired up properly, then grab a spare PSU and hook that up.

think it could be the power supply? I used the same one from my old computer, but that was a 20pin mobo and this one is 24pin; but the MSI manual does say it supports 20pin.

Could the heatsink not be flush with the surface of the CPU and therefore the CPU overheats and the system powers down?

That quickly though? I mean the heatsink has all 4 screws screwed in...unless somehow it's still not flush. Although I don't think that in the 1 second it's on it could already be overheating...

It takes about 10-15 seconds for CPU to overheat and destroy itself. So Yeah. BIOS may also follow the rapid heat buildup in the socket and shut it. There are many ways heat will make system shut itself.

These are all possibilities would not hurt to root it out and check it.

Yeah, don't do that.

I took it back to the place that I bought and and I was explained to how the anti-static bag will actually conduct electricity and that I fried the board. ...

Static can harm them, but you won't generate static or hurt anything by setting it on a desk. I wouldn't lay it on metal or carpet.

I'd bet it's improper grouding. You've got something touching something where it shouldn't. Remove everything including motherboard tray if you can then reinstall everything.

That happened to me before. I'm not sure what it was. To be honest I think it was something stupid like something not connected right.

haha yeah.
Opposite of static is conductive.

so I must have just blown up my old PSU, I went and bought an antec 650 and I'm installed windows right now.

I'm just happy I didn't blow up anything else...

*Looks slightly smug*

Don't worry to much, usually when a PSU is causing problems, its simply not providing enough power. Of course they can go dramatically bang with the smoke and the dead motherboard and the crying and the random violence that tends to follow, but its fairly rare.

 

[Asus]

Thankfully it is rare. hehe

That reminds me of a time when I was working at Compusa. A co-worker and I were looking at a case we had just got in and it came with a power supply. We decided to do a quick search online with the PSU model number to see about any feedback or reviews. And the very first google result linked to a forum post with the user exclaiming that it blew up on him etc. Was pretty funny at the time.

I actually had a Seasonic 600W blow up on me once, little flash out of the back to accompany the loud cracking sound ! Hehe

xD

Turned out to be a faulty batch and the replacement has been running happily for the past year and a half.

I've got a brand new PSU that I never used. Had it for about 6 months. I had left my sunroof open, and there was an inch of water sitting in my car; and the PSU was in the box on the floor.

The box acted like a napkin.


Anyway, Some water got in it, when I found it, I shook it out and 'hung it out to dry'. I know from experience, if something electronic gets wet, you should give it _plenty_ of time to air out. Like a week or more. Putting power through it when it's damp and it will probably damage/destroy it.

It should work, but, I don't have a use for it anyway.

anyone wanna buy a 'brand' new PSU? :naughty:

(i'm joking)

So that's why there were a number of low ratings for the Seasonic 600watt model @ newegg. hehe
