computer won't power on

[roblob]

I opened my case today to clean out some dust from inside my computer. After finishing cleaning it out I turned the computer on before putting the side to the case back on. As I was putting the side of the case on the computer suddenly shuts off and starts back up within a couple seconds. I continue to put the side on but again the computer shuts off and starts back up. This time I turn the computer off my self and secure the side of case on. I now go to turn the computer back on except, nothing happens now. I check to make sure everything is plugged in, but still nothing happens when the power button is pressed except sometimes a light on my videocard will turn on for almost a second and then go out. What could be the problem?

I have a Gigabyte P35-DS3L, core 2 duo e4400, hd 2900xt, ocz platinum revision 2 (2Gb) memory, and Abs Tagan ITZ series 700w.

Thanks

short somewhere in the case.

Could've been static off your hand killed something inside. Probably the Power supply. Do you have any other PC's or power supplies at hand to use for comparison? I would take out the PSU, and try running the system with a different one, just to see if it will boot.

that was one of my first thoughts but the only other power supply that I have right now is one from a 250 watt one from a 5 year old dell. I thought dell didn't use standard parts and everything so I won't be able to run it off that?

It's not the power supply, someone on Tom's Hardware told me to start the power supply without the computer and the power supply started fine so it's not that

so I put the psu back in now and tried to start it now with cdrom and hard drives unplugged, unplugged all peripherals, took out all pci cards and my video card. Basically all that happened is the fan moved a tiny bit and then it stopped. what do I do now?

 

[robisbell]

get a new case, migrate to it and test, if no joy, the boards dead.

 

[roblob]

what would using a new case do?

 

[Dillybob]

I'm not really sure, but the case has been a problems in several similar situations....

hopefully you get one without a shorting problem and then you can reliably test the hardware.
