So the issue is that I had bought the PC is Australia and set it up there. All worked fine with no issues at all. Last month I had to come back and so I pulled everything out to take with me on the plane and then reassembled where I live in Spain with a new case.
This is where the issues start and Ive spent 2 days troubleshooting to no avail.
The PC turns on and then turns off again 3 secs later and repeats this until I turn the PSU off. When this happens:
All the case lights come on and I can modify lights and speed.
CPU, and GPU start up
HDD boots up
Once I got it to boot up and start booted up but I had no signal from the graphics card. This was when the card was not quite seated properly so I turned it off and screwed it in. Once this was done the same turn on/off issue returned.
Side note: I have the modular toughpower but left the module for SATA power for the HDD in Australia and am using a molex converter, could this be the issue? I dont think so but its worth covering that as well.
Any help would be great as Im running out of ideas.
Thanks for the quick response, Ive narrowed it down the GPU, if I take the grahics card out then the pc stays on. What should I look at barring checking another card as I do not have one available. Thanks again, don´t know what I do would do without PC forums!!
OK so narrowed it down further, if I take the guts out the case and try it it works fine. As soon as I put it back in the case the problem persists. I´ve checked the case over and over to see if there is anything that could short it and cannot see anything so stumped.
Any suggestions helpful as I´m trying everything at the moment.
OK so for those that may have the same problem the GTX 275 for some reason was shorting the board. Stuck cardboard on the bottom pegs that hug the mobo and on the top where you screw it to the case and whoohoo PC is back up and running. Took about 10 hours of trial and error but finally got it.
