Why will my fan not run during use but i hear it when the computer powers up?


Fans, mainly the CPU fan, have a speed control which slows the fan down. This is usually controlled by the BIOS. The speed is based on temperature of the CPU. If it's cool with little load the CPU fan will run very slowly and you won't be able to hear it. On startup all fans ramp up to 100% until the BIOS takes over and slows the fan down.

Tip

Computer CPU/Processor maxed 100%


Is your computer experiencing a CPU that is running at 100% Is your computer experiencing slow performance?

You can view your CPU utilization and other performance stats using Windows Task Manager. Press Ctrl + Alt + Delete and bring up Task Manager. Go to the performance tab.

The top of this screen should show your CPU stats.

In Linux you can use the TOP command,
Type the top command:
$ top

A CPU that is running at 100% utilization is not necessarily a problem. When the computer is booting up, or coming out of sleep mode, it may max out the CPU which is normal. The CPU will be utilized fully in order to bring the computer up as fast as possible. Some computers will even utilize the CPU while it is idle, to complete background task such as disk cleanup and file reallocation.

A problem will occur if the CPU stays maxed out. If it stays at 100% for more than a couple of minutes, you may be experiencing degraded computer performance.

Steps to reduce performance degradation.

-In a limited number of cases, software bugs can cause CPU utilization to spike. You will know this is the case if you are using a computer program(that is not hardware intensive like photo/video editors) and notice degraded computer performance. Check your CPU stats while running the program. If this is the case, check online for solutions and possible upgrades which resolve bugs in the software.

-You can reduce Windows start up programs, which will speed up the boot/wakeup process. You can do this from the MSCONFIG window. Go to Start > and in the run box type "msconfig". Go to the "startup" tab and you can uncheck which programs you do not want to start with Windows.

-A majority of the time a computer will get to a point were the hardware will need to be upgraded in order to handle the work you are doing. Common computer upgrades are memory, cpu, motherboard and hard drive.

100% cpu usage


In Task Manager, go to the Processes tab and sort by the CPU column. See what is hogging up all your CPU. It may be a virus, if so, I recommend downloading Malware Bytes and doing a full scan. Warning, it could take several hours to scan depending on the size of your machine. Good luck!

My Toshiba satellite pro M10 very slow.


check your system performance thru task manager. check for CPU usage. usually COU usage is 1% to 10%. if your CPU usage would peak from 10% to 100% there is a huge possibility that there is program running on your computer that eats up your memory. Or it could be spyware/malware

My computer moves slow from outta nowhere


Completely remove avg and re-install 8.5 see if that fixes the issue. Speed almost always has something to do with how much Ram you're running. Check your cashe' to be sure it's set high enough. Many anti virus programs are very comsuming of memory.

Good Luck

Advance Bios Set up (CPU frequency (MHz) setting)


Your computer is telling you there is a problem with either the memory or the interface between the motherboard and the memory. There is a utility you can use called memtest. I would run that and see if you get errors. Often it is easier to simply try a different piece of memory in the slot, because even if you detect errors it could be due to the interface and not the memory itself.

But the first thing you should try is power off the computer, remove the cover, blow all the dust from inside the case, remove the memory and blow all dust from the memory sticks and slots, then put it back together and try again. This is free and solves the problem about 20% of the time.

Good luck.

Slow


Hey
There can be many things that can cause your computer to slow down.
First of all Viruses .. some viruses once in the computer are difficult to be recognized by normal anit-viruses they generally make your computer go slow, such a problem can be solved either by getting a better anti virus or by formatting your system
There can be another reason... have you check how many processes are running on your comp?
ctrl + alt + delete go to processes... now a normal XP os needs only 17-20 applications to run properly ... so anything in excess to it is being run on your computer to provide some sort of service to you(you must not start stopping those extra processes w/o knows what they are doing).Try closing some of the applications this should make your computer work faster
There can be another reason... the drive space in your OS drive Say Drive C is very less ... should be above 500 Mb for smooth functioning.. in such a case delete unwanted files..
for further assistance feel free to mail me at
