Run speedfan, and see if you see a Temp go up and up and reach a certain point, then the computers shuts off!! http://techvividglobalservices.com/solved-computer/solved-computer-power-won-t-say-on.html

Sometimes, the only way to diagnose a problem is to disassemble the computer outside the case or remove components one by one. This complexity is only defined with respect to a probability distribution over the inputs. Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply. This means an algorithm for multiplying two integers can be used to square an integer.

I'll be home in about 2 hours or so, and I'll definitely post my SPECS on here. If its running time is, say, n15, it is unreasonable to consider it efficient and it is still useless except on small instances. The card works hard on Ultimate Settings and works super hard to maintain smooth play, but mine stayed in operable temperatures, I suggest you stay at high/med just so that the

- You can see pictures from this wikipedia article.
- An important unsolved problem in complexity theory is whether the graph isomorphism problem is in P, NP-complete, or NP-intermediate.
- Turing machines are not intended as a practical computing technology, but rather as a thought experiment representing a computing machine—anything from an advanced supercomputer to a mathematician with a pencil and
- If keeping that power supply in there, then you need to find the trigger.
- This means that the reduction process takes polynomial time.
- For this reason, complexity theory addresses computational problems and not particular problem instances.

You can also run a Memory tester (I use http://www.memtest.org/). If shaking the case can temporarily fix it, it might be a bad cable, or a cable that isn't solidly plugged in. A CCM membership gives you access to additional options.

Since complexity theory is interested in classifying problems based on their difficulty, one defines sets of problems based on some criteria.

Although time and space are the most well-known complexity resources, any complexity measure can be viewed as a computational resource.

XFX Pro 650W Power Supply Unit (Core Edition) solved PSU: What size power supply unit do i need? check my blog It is believed that if a problem can be solved by an algorithm, there exists a Turing machine that solves the problem. I asked them to do a diagnostic test and left it with them. make sure it's properly plugged in.

Sometimes it works perfectly fine and never turns off. The boss of my boss invited me for lunch, should I let my boss and colleagues know? These include various types of integer programming problems in operations research, many problems in logistics, protein structure prediction in biology,[4] and the ability to find formal proofs of pure mathematics theorems.[5] this content A problem X is hard for a class of problems C if every problem in C can be reduced to X.

Important complexity classes[edit] A representation of the relation among complexity classes Many important complexity classes can be defined by bounding the time or space used by the algorithm. it could be the power button if your power supply is working. when I press the power button, absolutely nothing happens (i.e., no fan, no power, nothing).

They are some of the very few NP problems not known to be in P or to be NP-complete. I do not have a spare power supply to test, will try to get one from somewhere. –Felix Sep 20 '10 at 16:15 @Felix You could try putting that All Rights Reserved Tom's Hardware Guide ™ Ad choices Articles & News Forum Graphics & Displays CPU Components Motherboards Games Storage Overclocking Tutorials All categories Chart For IT Pros Get solved Question about Power Supply and New Computer Parts solved Is My PSU (Power Supply Unit) Is Good ?

Is a Red Court Vampire's addictive saliva useless in combat, or am I missing something? There are many different types of reductions, based on the method of reduction, such as Cook reductions, Karp reductions and Levin reductions, and the bound on the complexity of reductions, such The input string for a computational problem is referred to as a problem instance, and should not be confused with the problem itself. have a peek at these guys Hardware Printed circuit board Peripheral Integrated circuit Very-large-scale integration Energy consumption Electronic design automation Computer systems organization Computer architecture Embedded system Real-time computing Dependability Networks Network architecture Network protocol Network components

Other machine models[edit] Many machine models different from the standard multi-tape Turing machines have been proposed in the literature, for example random access machines. When the CPU reaches a certain degree, the computer powers off immediately. Written as an accompanying text for courses on network protocols, it also provides a basic tutorial for those whose livelihood is dependent upon secure systems.

Since the time taken on different inputs of the same size can be different, the worst-case time complexity T(n) is defined to be the maximum time taken over all inputs of
