Why your CPU fan goes loud sometimes and goes back to normal by itself what could be the problem?
Your computer adjusts the fan speed depending on the workload it is receiving, this can be due to applications running in the background and operating system tasks that you may not realize are happening but still cause a spike in CPU activity. so to compensate for the extra heat created by the increase in activity the fan runs faster for a short time. if this seems to be happening a lot with little or no visual load on the computer then look for unwanted applications in the start up tasks by typing"msconfig" in the run window. if that still doesn't work consider buying quieter CPU and case fans if you are comfortable installing them yourself.
you should also check to see if you have enough RAM, computers with not enough ram spend a lot of time swapping memory between the hard drive and RAM thus further adding to their workload when multitasking. to check if ram an issue then hit ctrl-Alt-Del next time the fans start to become a problem and look under the performance tab to see if the page file history has had any recent spikes.
hope this helps.

A lot of software does not support many core systems, sony Vegas is one of them. These softwares are single threaded softwares and use only one core.
What does refurbished CPU mean?
maybe good maybe not i brought one from geeks it fried my motherboard they refunded the CPU price. i lost my motherboard and the cost of returning the CPU.

Refurbished = repaired. like any refurbished item there was a problem that the manufacture has attempted to repair and they are re selling the item at a reduced price. Occasionally the problem is not fixed and it can occasionally be responsible for further damage to related systems. Personally I estimate about 10-15% of refurbished items I have purchased have failed to preforms properly. Of these I have not personally had any damage other components, but know others that have had this problem.
Purchasing a refurbished item is a low risk method of getting something on the cheap.
Good Luck, hope this helped.
Unfortunately, in the US, the term "refurbished" does not have a set meaning. Businesses can legitimately use the term to cover any of the following conditions:
Returned - items which were shipped to the customer or bought at retail, and then the customer returned them, for any reason. This may include "open-box" returns - where the customer merely opens the box, discovers that item wasn't the one they wanted for whatever reason, or perhaps was missing something - "DOA" returns - where the item did not function immediately - or "malfunction" returns - where the item worked for some period of time before dying.
Repaired - items which either were sold to a customer who returned it for malfunction/non-function, or items which did not pass the seller's internal QA process. Generally, any item which fit under one of the other categories here which needed some sort of technical repair before becoming operational again.
Refused - technically returned items, this tends to be a special category to indicated that the customer didn't even open the item - it was either immediately returned (still in shrink-wrap or with unbroken shipping seals) or the shipper indicated that the customer refused to accept the item, usually because of obvious damage during shipment. Some jurisdictions allow the seller to re-sell the item as "new" if it was returned still sealed, but many others do not.
Used - this can cover a variety of cases, usually one where a customer has purchased the product and satisfactorily used it for some time then either sold it to another or returned it in exchange for some consideration (usually, a trade-in upgrade). It also covers "Display Model" items, which were new items being used by the seller to show off the features of the item, or items which the seller had been using for any other internal purpose. Many sellers use the term "reconditioned" to indicate used items which have had a "sprucing-up" cleanup and checkup performed on them. In the car world, the equivalent of "reconditioned" is "certified pre-owned".
The key here is that the customer has bought AND touched the merchandise - as soon as the merchandise leaves the possession of the seller (including being shipped), it can no longer be sold as "new".
If the seller is indicating an item is "refurbished", it is allowed to have some cosmetic flaws (dents, scratches, signs of wear). However, unless the seller specifically states that the item is sold "AS-IS" (it must be the exact phrase "AS IS") or explicitly lists known flaws in the item, the item must function identically to one which is new.
In the case of CPUs, repairing them is really not possible - even if it's just a broken pin. Also, absent specific manufacturing DESIGN flaws (such as the fdiv bug in 1st generation Pentiums), CPUs either work as designed, or fail completely. So, a "refurbished" CPU being sold is almost certainly either a returned "open-box", a refused item, or a used item having been pulled from a functioning system. You should be able to tell by looking at the item which is the case (the first two will look like brand-new, the last, even after cleanup, should still be obviously used).
Note that even if you are buying it as "refurbished", you have the same rights as buying it new, with the "AS IS" exception noted above. "AS IS" is the legal term for buying junk items; the seller makes no claim that they work in any manner, and the price should reflect that risk (i.e. any item sold AS IS should be priced at a fraction of a current, working USED equivalent). Otherwise, you have the right to return the item immediately (i.e. within a few days) after discovery that the item was Dead or malfunctioning. Sellers MUST refund your money (less shipping, but NO RESTOCKING FEE) for D-O-A/broken items returned immediately. Depending on the seller's policies, they may or may not accept returns for items which are functioning as advertised (and may charge a restocking fee). In the case of malfunctioning items, the seller usually has the option to repair, replace with an equivalent item, or refund your money, at the seller's discretion. For DOA items, the same choice applies, but at the customer's option, not the seller's.
What is clock speed of i7 processors?
The clock speed of an i7 processor can range anywhere from 1.70 GHz to 2.90 GHz depending on the quality and brand. Some processors are built better than others resulting in better clock speeds.
Is multi core and dual core the same thing?
Multi-core means any number of cores greater than one.
Dual-core is a multi-core with exactly two cores.
Is it better to use one more powerful processor or multiple less powerful processors for my PC?
It is better to use one more powerful processor for responsiveness. Consider this: you have two processors that process some transaction at a rate 1 transaction per second. They would process two transaction in one second each resulting in 1 second average response time and throughput of 2 transactions/sec. Now if you have another single processor that is twice as fast as the other two and it has to process the same two transactions then results will be a little different. It would finish the first transaction in 0.5 second and the the second in another 0.5 second resulting in the same throughput - 2 transaction/sec but 0.75 average response time.

What is STA 3000H in microprocessor?
STA 3000H is an 8085 instruction that says to store the accumulator at memory location 3000H.
Can i upgrade emachines e627 with amd phenom processors?
No. The eMachines e627 will only physically accept an S1 socket processor. The Athlon X2 is an AM2 socket processor. You will need to go with an AMD Turion X2. And even then some Turion X2 processors may not be supported by the BIOS. The AMD Turion X2 TL-50 should be supported and should be free of heat issues as the dual core version of this laptop was shipped with this processor. I have read of users successfully upgrading to the AMD Turion X2 TL-58 and TL-64 without issue. However, that is not first hand knowledge on my part. I have the same laptop with the single core TL-20 and am about to upgrade to the TL-64.
What you used with the CPU heat sink or fan and what is the difference between them?
Heatsinks and fans are used on CPUs to help cool them down so that they are not destroyed. A heatsink is a piece of metal placed on the CPU to distribute heat away from the CPU itself.
What is a cache outside the processor called?
L2 cache.
Today's processors all have some memory on the processor chip (called a die). Memory on the processor die is called Level 1 cache (L1 cache). Memory in the processor package, but not on the processor die, is called Level 2 cache (L2 cache). Some processors use a third cache farther from the processor core, but still in the processor package, which is called Level 3 cache (L3 cache).
Is the Intel celeron 900 at least SSE2?
No. SSE2 was introduced with the pentuim 4, and no pentuim 3 type CPU (which the celeron 900 is) supported SSE2
Parity bits are used as a form of error checking during the transmission of information. When old modems transmitted data over a network or communications device, the data was encoded into a series of ones and zeros called bits (modern modems send information in packets and check for errors in different ways, so a parity bit is unnecessary). A single bit can describe only two possible states, 0 (off) or 1 (on). Several bits are thus needed to describe a letter or number. A total of seven bits are used to describe the set of ASCII characters, which include the letters and numbers that compose this document. The letter "A", for example, has ASCII code 65, which in binary is 1000001. Note that each binary digit corresponds to a power of two, and 65, which is two to the sixth power plus two to the zeroth power, has ones in only the sixth and zeroth columns of its binary representation. The letter C, with code value 67, has the binary sequence 1000011. Because noise or electrical interference may sometimes interfere with the transmission of data, it is useful to have some way to easily detect errors in information as it is exchanged. One way to do this is to add an eighth bit to characters that are transmitted, called a parity bit. The parity bit is chosen such that all correctly transmitted characters will have either an even or odd number of ones. Thus, if a zero were placed at the start of the code for the letter A, producing 01000001, a one would be placed before the code for C, producing 11000011. The prefixes shown here produce binary codes with an even number of ones (and zeros), and the added bit is thus called an even parity bit. The leading ones and zeros could also be chosen to always produce odd numbers of ones and zeros, and this scheme is called odd parity. Familiar settings in communications programs are E7, which uses one even parity bit and seven data bits, and N8, which indicates no parity bit and the use of all eight bits for transmitting data. Use of the wrong parity setting in a communications program may produce screens full of garbage characters. If this happens, check to see what parity settings the computer to which you are connecting expects. If you do not have this information, try connecting with a different parity setting and see if this produces legible text.
How is the brain and a CPU alike?
A brain is one of the important things in the body (the other is the heart), without your brain, you cannot do even the simplest things that you have to do as being. (An example of this could be breathing. You know how and when to breathe because you have a brain. Without it, people will not know how to act properly).
A CPU, on the other hand, is somewhat the same as a brain to computers or any other devices.
But it is very obvious that as an organism or a living being, you cannot have a CPU for a brain.
What is a CPU and what is its purpose?
CPU (Central Processing Unit)The CPU, also called the processor or microprocessor, is the most important component in a PC. The CPU receives data input by the user, processes information and executes commands. In a PC, the CPU is housed in a single chip called a microprocessor.
1- The main purpose of the CPU is to execute programs. It does this by doing three basic steps.
a) The CPU uses it ALU (Arithmetic/Logic Unit) to perform mathematical operations like addition, subtraction, multiplication and division.
b) Moving data from one location in memory to another.
c) Making decisions and jumping to a new set of instructions based on those decisions.
2- It's works as brain of your computer...
3- CPU purpose is to quick reading data
4- Its give the instruction to your computer.its the hard of your computer
5- it is the main processor in a computer that processes all the logic statements put to it.

What is 3 byte instruction in microprocessor?
A two-byte instruction gives the specific function instruction in two bytes, or two words. The first specifies the opcode, which tells the microprocessor what operation will occur. The second specifies the operand, or the data that the operation is done on.
