If I had all these problems with the system ive just sent back then whats to say I don't get it again with another sandybridge system.
A consumer magazine created minor problems to PCs. Most computer shops never fixed the problem But they did get a lot of perfectly good parts replaced. It is called shotgunning. It is performed when a tech has no idea what the problem is.
Solutions are a two step process. First all facts are collected so that the problems (suspects) are known. The fixing / replading something comes a line time later.
This is, for example, why more responsible computer manufacturers provide comprehensisve hardware diagnostics for free. All have them. Only the more responsible provide them to techs and you.
So, you must work with lesser information. Do you also automatically plane all doors when they become sticky or disloddged? Of course not. You first inspect the foundation. Identify why that unacceptable failure exists before fiixing anything. An informed tech does same for you computer. That foundataion is its power supply system. Informe techs know a PSU is only one component of that system. And the entire system can be confirmed in one minute using a multimeter when the computer is accessing (multitasking to) all peripherals simultaneously. Numbers from six wires are provided by a tech who is doing his job. You can do same with a multimeter sold to 13 year olds in Kmart. Also sold in most any store that sells hammers because it is that dumb simple. Best purchased in some stores for $5 or $17.
Once those numbers are provided here, then fundamental system functions are identified definitely good or definitely bad. Any other answer means no useful information. Once the answer is definitive, then either the suspect to replace has been identified. Or we more on to the other known suspects.
You will discover large numbers of 'experts' are hearing this for the first time. Had no idea that he power system is more than a PSU. Have no idea what those numbers are reporting. In part, because an A+ Certified Computer tech need not learn how electricity works to pass the test. Which is why that consumer magazine had so much trouble finding anyone who could actually fix the problem
Welcome to the whys your problem (including no comprehensive hardware diagnostic) and why you have so little reason to believe a solution will be implemented. Too much "it could be that or might be this" thinking. Too little facts with numbers that define a problem before it is fixed.
Let's address some other popular myths up front. Neither a UPS nor protector will solve dirty power. In fact, your incandescent lamps must dim to 40% intensity. Even that is perfectly ideal power for all computers. Any 'cleaning' done on AC mains is completely undone inside every power supply. First the supply makes that voltage much higher (well over 300 volts) and converts it to very dirty radio waves. Clean power is created by first making power dirter. But that is not understood by many who have no idea what a power supply does.
Dirty mains or 'cleaning' power with a UPS are just myths created when one has no idea how electricity works and how computer power supplies work. In fact, those suggestions are identifying the techs with least technical knowledge. 'Dirty or cleaner' AC power quickly identifies which techs to keep your hardware away from.
