PC power Failure

[gnostic57]

After installing a new graphic and sound card my PC suffered a power failure and the video card, power supply and hard drive had to be replaced. What caused this power failure?

What are your computer specs? And are you sure there is nothing else that could have shorted the PC? Ive had this happen to me once, it was with a graphics card that needed extra power directly from the power box, and somehow I did something wrong and I had to replace my graphics card... Never figured out what though. I probably gave it too much power.
