Wow. That "repair" shop is incompetent.
Obviously if components are randomly failing and you replace them and they CONTINUE failing... you don't need to replace them AGAIN.
Random Failure = POWER SUPPLY... almost always.
Especially if you replace the part and it still fails.
What you need to do is get a program like Motherboard Monitor and watch the voltage on the powersupply rails. Especially when the system is under heavy stress (like when playing a game).
There is no set range of tolerance that defines a PS as "bad", but if you are seeing significant variance along the 12V, 5V and 3.3V rails... replace the power supply, preferably with a larger one.
Make sure you get a PS big enough for all the parts of the system... if it's a gaming system I'm assuming it has a big video card like a Radeon 9500\9700\9800... those things instantly make your system need a very heavy duty powersupply.
Frankly, it may not be that your current powersupply is bad... just that it's being overdrawn. The topic of how to get the "right" size PS is a topic that one could write pages about, but it is always better to error on the side of overkill since PS's are fairly cheap components.
