Users complaints are minimal when new Personal Computers are rolled out, they start up quick, shut down fast and programs seems to open in a snap but in time, users begin to notice that the system is slow or that it hangs up often, where the possibilities for system slowdowns are endless.
For me when computer started slowing do, I feel like crashing the computer and destroy the whole thing, cause it wont let me do all what i want in a snap, slow loading files, slow opening files, slow shut-down, slow boot up, slow in everything, you get embarrassed by your computer when you are at work or when you are doing something important for somebody.
I have identified these problems and narrowed them down to 4 lesser problems that cause systems slowdown.
PROCESSOR OVER HEATING
Modern processors generate a lot of heat that’s why all processor require some sort of cooling elements, typically a fan of some type. When the processor temperature goes over spec. the system can slow-down or run erratically.
The processor fan may fail for several reasons:
- Dust is preventing the fan from spinning smoothly
- Fan motor has failed
- Fan bearings are loose and “jiggling”
When a PC gets low on memory, Windows relies on a process called paging to move page of memory (Not currently being used) from physical RAM to a swap file (virtual memory). The page is stored in the swap file until its needed again, at which time the page is moved back to the physical RAM. Not every memory page can be swapped, though. Some pages that contain critical operating system data must remain in RAM. Like wise some RAM is consumed by the swapping process itself. This means that at any given time, less memory is available for data than you might think. Although swapping is a normal process, excessive swapping called trashing is a big problem. Trashing occurs when data is constantly moved between RAM and virtual memory. The biggest symptom of trashing is that the PC runs very slowly and the hard disk is constantly running. The best way to stop thrashing is to simply add more memory to the PC.
One often ignored culprit of system slow down is the machine’s BIOS settings. Most people accept the BIOS settings as they were configured in the factory and leave them as it is. However, slowdowns may occur if the BIOS settings do not match the optimal machine configuration. Often you can improve machine performance by researching you mother board’s optimal BIOS settings-which may not be the same as the factory defaults. There is no centralized database of optimal BIOS settings, but you can employ a search engine such as Google and use your mother board name and BIOS as key words to find the correct settings.

HARD DISKS FAILURE
There are many signs of imminent failure before a hard disk finally gives up. Some of these signs include.
- Slow access times on the affected drive.
- An increasing number of bad sectors when running ScanDisk and chkdsk.
- Unexplained Blue screens
- Intermittent Boot failures
Detecting a failing hard disk can be tricky because the early signs are subtle. Experienced computer professionals can often hear a change in the normal disk spin. After the disk deteriorates further, you’ll see the system crawl to a standstill.
When you notice the system slow down, run ScanDisk or chkdsk, depending on your operating system, if you notice a bad sector where a good sector existed earlier, that’s a clue that the disk is going bad. Back up the data on the disk and prepare for it to fail soon. some of this write up may be found at TechRepublic
