GX270 shutting off
Computer Suddenly Turning Off

This series has had a major known problem with bad capacitors supplied from the far east on Killer Bee and Jazz motherboards, causing power downs or lost video. Look at the top of the capacitors, those tall can-looking components on the mother board. They should be flat, scored with a K, a T, or an X, and should NOT be leaking brown goo, bulging, or domed at the top. I've recently replaced over 200 motherboards for this problem - 270s made in the early to mid 2000s.

PC SHUTS DOWN
Computer Suddenly Turning Off

Ive had my pc for almost 4 years now and at the start was working brilliant.My pc is from aldi superstore.It has been switching off on it's own for some time now.Before it was doing it regular so I contacted medion who sent an ( expert ) who replaced the power supply a new graphics card and new motherboard.It took him a while to get the pc to boot but eventually everything was as normal and no shutting down.Now I have tried to burn discs and it gets to about 30% then the pc shuts down.Sometimes playing games it shuts off and looking at video on intenet.This is guiding me to either overheating which I do not know what to do or the graphics card or finally something wrong with the processor.Other ideas I have had are too many plugs in one circuit breaker,memory cards not fast enough only have 512mb ram.Please can someone help
