I have a hardware problem and would like to know if I have damaged my motherboard, whenever I try to switch my pc off it keeps restarting (windows closes down easily) and when I have switched it off at the psu switch it won't power up (motherboard lights up, acts like it's dead otherwise) until I tilt the pc over. I remember the white plastic clip bit of the pci express slot breaking off when I tried to fit a my nvidia 8800 gts graphics card, would it be because of this or the power supply?
I have an Antec 550w psu, an Abit motherboard with 2gb of DDR memory and a Athlon 3700 cpu running Vista Ultimate, I have no obvious problems with Vista.
Thanks for any help.

Would be the Power Supply being faulty. If the Antec PS is still Under Guarantee return it for replacement and that may cure the problem.

You are unlikely to have damaged the M'Board and the PS is unlikely to have allowed any power spikes through that would allow the M'Board to suffer damage either as these units work very hard to protect what's inside the case from harm. What normally happens when you have a faulty PS is that the computer will start to boot and reach the Windows Splash Screen and then restart before the Splash Screen disappears.

that this may be related to improper memory or the video card. How does it react if reseating the memory, and pulling the video card out?

Last time I had a system that needed to be physically altered to power on, it was due to a bad memory stick. What was funny about my exp. was if you tapped on the top of the unit, it would power upo fine.... Lol

Anyway, if the video/am does not help, it looks like the power supply or switch should be replaced.
