Simple hardware problem, my pc doesn't start and I believe it's the jumpers so I'm gonna have to buy a new motherboard.
It worked for an hour but white smoke came out of the jumpers and now it doesn't start and when it did I had to unplug the computer and after numerous tries it turned on.
Tried another PSU and case but same thing, so I imagine it is the mobo but I want to hear what H thinks before I make a dumb purchase.

Oh yeah and any recommendations on a cheap reliable mobo, I just needed to work on my x2 3800xy, g.skill 2gb and 7600gt, money is tight.

Thanks
 
what? :confused: Did you change any jumpers? If not, then what makes you think its the jumpers? Does your board even require jumper configs to startup? Jumpers shouldn't smoke -- its a bad habit. :p Do you see any burn marks on the motherboard anywhere? If it turns on, whats the problem?
 
Took my mobo on a trip and when I tried to set it up it didn't work, stupidly I put the jumpers incorrectly on the mobo and nothing happened, read the manual and now everything was peachy sorta (white smoke from jumpers) and it boot up. After an hour it powered down. Tried a second time but had to unplug the Psu numerous times in order for it to turn on (after 2 hours power down). The only thing that happens when I press the power button is it tries to boot up and the fan on the processor starts moving for a second but it stops and that's the only thing that happens, no sound or beeps.
And now it doesn't start so I guess the little pins on the mobo are screwed, gonna check if I see any burn marks. What else could it be, all other components are working and even tried another PSU. Tried removing the videocard and RAM but still it doesn't start.

In a Nutshell: Press power = dead
 
It could be a dead/dying PSU, so try another one. It could also be a short, so put your mobo on its cardboard box and do a barebones bench test. See the troubleshooting guide sticky for more info.

Tried 2 PSU's and both work (one works on another motherboard)
Will do the cardboard box thingy, thanks for the advice.

Ok so I did the troubleshooting found on the sticky and still have the same problem?
So what do you guys think?

Thanks
 
Solution to my problem

Bought a new mobo and same problem, tried another house just to make sure it wasn't my house. So I thought it was the CPU at this point since that's the only thing that would make sense. Tried the "old" mobo on a cardboard box and it booted (sometimes it's normal for my pc to boot). I remembered the last time it boot on a cardboard box with out a hitch.

Solution: Run mobo on a cardboard box. Been hitting my head for weeks now and this is the stupid solution.
 
LOL!

Well time to look over your case. Look for a loose screw, wire, cable, standoff, washer, etc.
 
This is a fun game... its called find the short. Too bad we can't play with you... but good luck!

Thank god I don't have to play that game, found out that the problem was the screws...yes the screws. Unscrewed the motherboard and is currently working and haven't had any problems.
At this point I don't care to understand, will just enjoy my pc and my new Left 4 dead game :)
 
lol, wha? :confused: so your mobo isn't screwed down? lift it out and look under... there may be a standoff you're not using causing the short.
