Crazy Motherboard Problem!

post #1 of 6
Thread Starter 
Hi,
My PC kept shutting down after 10-30 seconds of switching it on, when I removed everything and just used the MB, CPU and GPU and PSU, i found out that when my MB was lying down horizontally, it used to work but when it was in a vertical/upright position it switched off. I removed the pins from the case to see if this was shorting but i still had the same problem. Eventually, I removed the GPU as well and just had the MB, 1 stick of RAM and the cpu attached to the PSU but i still have got the same problem.
Im totally stuck so any help/any ideas on what the problem is appreciated.
Thanks

yeah its not an overheating problem, because the PC still works with the case closed, just in a horizontal position

It actually could be. Some heavy heatsinks pull like hell in a vertical position, and sometimes there is no proper connection between the CPU and heatsink if it isn't mounted properly. Just try reseating.

Same problem on an old computer, the PC wouldn't start if it was laying on the side, otherwise an awful alarm would go off until manual shut off. So PC never goes on shutdown.

As soon as I move my PC upright it just switches off. Ive also reseated my HSF a couple of times but i do agree that the new Intel ones with the C2Ds are quite flimsy and easy to remove.
Perhaps I shoud RMA my motherboard?
