Power Supply or Motherboard issue?

[Capn Stabby]

Hello,
I bought a PC from buyxg/cyberpower in December after my Monarch Computers debacle.
I just got the case, motherboard, cpu, PSU and one stick of RAM. I installed everything else from salvaged parts from my old computer.

I noticed that the tower was super sensitive. Any nudge, even if it's closing the front panel would turn the whole thing off. I wouldn't be able to restart it until the 6-7th time turning the power supply on and off.

I finally had enough and did that paperclip trick with the power supply each tiem it happened, and reconnected it to the mobo. It would work fine - only massive-tip-the-tower bumps would shut it off.

But the biggest problem now is that it doesn't start up easily. I wake up, go to turn it on, and the LED fans flash for a second and nothing happens. I do that power supply flicking deal about 7 times, and it starts up with no problem.

Could this be the power supply? I asked buyxg (after 2 months of no response from them), and they said for me to send the motherboard in. The thing is, I'm in the middle of finals and I can't afford to be without a computer. That, and the only reason I bought from them was because I didn't want to deal with installing the CPU/mobo into the case.

Here are my specs:

AMD Athlon™64 X2 4200+

Socket AM2)GigaByte GA-M55SLI-S4 nForce4 SLI Chipset DDR2/800 SATA 16x PCI-Express MBoard w/GbLAN,IEEE1394,USB2.0,&7.1Audio

NZXT PF-500 500Watt Power Supply

Any ideas? Thanks!

you might want to unplug EVERYTHING inside your computer and reseed all your cards. Something seems very loose in your computer. Your power button may have a short of sorts so I would look carefully at your power switch between the button and your mb/ps.

Hmm, my 8800GTS is screwed in pretty nicely. That's the only expansion card I have.

I assumed the loose part was that mega (20 + 4?) pin power connector, so that's where I usually focused my attention.

Do you mean look at my power switch as in the connection between the case button and the motherboard? Those small rectangular headers?

yes..and the actual button itself. there might be something messed up with the switch itself.

I would also place some washers inbetween the motherboard and the case to rid of the statics that is sent thru your case.

Hmm, okay. I'll crack this open on the weekend and tweak everything.
Thanks!

I had this happen, it was a cheap PSU, and it ended up burning itself and a stick of RAM out. Not saying this is your problem, just sharing mine, after that I bought an ANTEC 480watt and its working great!

let us know, I also think that it's probably something loose in there. Might be a short.

Hi everyone,
I just wanted to give you guys an update. Sorry for taking so long, finals started this week and I was too busy studying this weekend to open the tower up.

I was fairly worried that if I turned it off, it wouldn't turn back on so I just left it off. That wouldn't be good :(

I reached the point today where studying wasn't worth it anymore, so I checked all the connections, blasted the dust off and reseated anything I could, including the power switch headers. I was wondering why the motherboard was loose on the upper right hand side, where the power connector is, and I found that they didn't put a screw in one of the holes connecting it to the case. I plugged a screw in, and the computer turned on on the first attempt!

That hasn't happened for weeks! Now I can sleep without being bathed in a blue LED light.

Now to see if it turns off if I accidentally jolt it. I'd rather not dropkick it to see if the power is still screwy, so I'll let you guys know in a little bit.

Thanks for all the advice!
