Why does My Computer Freeze?

 

 When your computer freezes your first reaction is to move the mouse. Nothing happens .The cursor doesn't move . You continue moving the mouse in the hope that it will come back to life. It never does. What causes this ?. Well In most cases this is caused by overheating. The first thing to do is switch the computer off. Pull out the power lead and check the processor . When your computer freezes usually something is overheating .Often its the fan on top of the processor. Is the fan hot? Is the heat sink red hot ? Maybe the fan is ok but usually on a processor there is some paste called heat sink paste or cpc paste. This cools the processor down. A few months ago I had a call out form a client who had called 3 callout companies before pc callout he said none of the companies could fix his freezing problem .He had changed the hard drive , the memory and the motherboard !! . When I first got the computer I was overwhelmed as the computer was a Pentium 4 3.06 gighz. The computer was built like a Maclaren f1 . It was very powerful. Initially I dint check the fan as it wasn't that hot . But after checking everything else I thought hold on , It must be overheating . When I removed the fan there was no paste on the processor . I applied some cpc paste to the processor and bingo !. The client was very pleased and kept my number. So when your mouse freezes on the screen usually something's getting to hot. Processor ,hard drive, memory check them all .In some cases though freezing is caused by software .What was the last program you installed? If you uninstall it does this fix the problem? Try to let your computer breathe .I have seen computers  placed in cupboards with no breathing space and the hard drive was overheating .Allow it some space to breathe and hopefully your cursor will keep moving. Overheating can also cause a blue screen.

Why Does My Computer System Freeze Up !

                                            Home Page

 

 

 

Do you see a lot of messages like, "This program performed an illegal operation and will be shut down" ? Or do you find that your mouse often freezes and you have to reset your computer to regain control?

 

This is a very common complaint for many computer users. Why this happens can be due to a number of things. The most common causes of these troublesome problems will be covered here. They fall into the following general categories:

 

           . Adware/Spyware: These parasites rob your system of memory, corrupt files, hi-jack your

              browser settings and cause your system to lose speed and performance. These programs

              can affect your internet browsing by adding pop ups and making cyber space a nightmare.

 

 

Hardware: Defective or mismatched components in your computer.

 

 

Aluminum Migration & ESD: Premature ageing and “Electro Static Discharge” can make a computer very intermittent.

 

 

Operating System: Some versions of Windows have bugs that can cause these problems.

 

 

Drivers: Buggy or down-level drivers can cause many problems.

  

 

Software: Some programs have bugs in them that can cause these problems.

 

 

Memory Fragmentation: Do you often see the message, "System is dangerously low in resources" If so you are probably suffering Memory Fragmentation.

 

 

CMOS Settings: Improper CMOS settings can cause many problems. Changing CMOS settings can also be used to help diagnose some hardware problems.

 

 

Loading Order: The order in which the software components of your computer are loaded into memory, at startup each day, can cause a multitude of odd problems.

 

 

A Combination of the above: Defects in any of the above may only show up under specific circumstances.

Question I get all the time when people are in the market for a new computer. What is difference between a Intel® Celeron Processor verses and Intel® Pentium 4 processor? The easies way for me to explain this is to compare the processor with a car engine. Lets said the Intel® Celeron is the same as a 6 cylinder engine. The 6 cylinder will take you anywhere want to go. It's less expensive to buy, and very dependable. But there are times when you need extra power. Maybe for hauling a heavy load or for going up a steep hill. The six cylinder will do the job but, a V 8 will do it better. The P4 is the V8 engine, capable of doing computing tasks that require more power. P 4 are more expensive but more powerful, it offers you that extra boost if you need it. The question, what is Intel® Pentium 4 with Hyper Threading? The P4 with H/T Technology is a P4 that is supper charged. Allowing multiple threads of data to be process at the same time. In a system using Windows XP the OS thinks that the system is running 2 processor at the same time. This allows you the run multiple processor intensive programs at the same time with out slowing down the system. So you see the type of processor you choose should be based on what you plan to do with your computer. I hope that this information is helpful to you and it clears up these question I often get.

 

 

 

The Specs Explained

The vast majorities of people buy a PC to browse the Web, check and send e-mail, and perform word processing or spreadsheet work. Today, processor power has gone beyond what any of these tasks demand: Even the least-expensive, lowest-of-the-low-end PC can perform any of those jobs admirably. For less than $1000 you should be able to pick up a PC and monitor that, a year ago, would have resided at or near the top of our Top 10 Power PCs chart (click on the PC World's Top Rated PCs links in the left column for examples). The only reasons to exceed that price are if you want the latest doodads, if you're a gamer or you're interested in digital video and strain your PC for every iota of performance, or if you include additional peripherals like a printer or scanner.

Most vendors let you customize and upgrade their base-model PCs with a mind-boggling selection of features. Need extra storage? Pick a newer, larger hard drive. Want a bigger monitor, but don't want to pay extra? Trade down to a slower processor or opt for a shorter warranty period (PC parts are more reliable than ever) to compensate for the extra cost of the CRT. Take your time and pick only what you need. And be sure to check our various Top 15 PCs charts before making your purchase. Below is a rough breakdown of some of your configuration options.

Feature

Low End ($900 and below)

Recommended ($900 to $1500)

High End ($1750 and up)

Installed memory (RAM)

256MB

256MB to 512MB

768MB and up

An important consideration. The more installed memory your PC has, the more applications you can run at once, and the better the system will perform. Upgrading memory in a desktop is a snap. (Compare PCs with recommended amounts of RAM.)

Processor (CPU)

2.1-GHz Athlon XP 3000+ or 2.6-GHz Pentium 4

2.2-GHz Athlon 64 3400+ or 2.8-GHz Pentium 4

2.4-GHz Athlon 64 FX-53 or 3-GHz Pentium 4

An important consideration. Determines how quickly the PC runs applications and performs many tasks, with speed measured in millions (MHz) or billions (GHz) of operations per second. AMD Athlon processors perform some tasks faster than Intel Pentium 4 CPUs running at the same clock speed.

Warranty and service plan

90-day parts and labor warranty, phone support during business hours

One-year parts and labor warranty, 24-hour phone support

Two- to three-year-plus parts and more than one-year labor warranties, 24-hour phone support and on-site service

An important consideration. A service plan provides a valuable lifeline for busy professionals or novice users who may not be able to repair difficult problems themselves. Check PC World's annual Reliability & Service survey, where readers collectively determine which PC makers provide the best and worst technical support and warranty service.

Graphics board and graphics RAM

Integrated (onboard) graphics chip

128MB NVidia GeForceFX-based or ATI Radeon card

128MB or 256MB DDR NVidia GeForceFX-based or ATI Radeon 9800 XT card

Somewhat important. The graphics board or integrated graphics chip generates all images on the PC. Graphics boards come with variable amounts of on-board memory; only hardcore gamers need the speediest, most advanced models.

 

 

 

 

Monitor

17-inch CRT

19-inch CRT or 17-inch LCD

19-inch or larger CRT, or 17-inch or larger LCD

Somewhat important. Many people can get by just fine with a 17-inch CRT monitor, but the prices of larger screens are dropping. Once-expensive 17-inch LCD displays are the sweet spot, while 21-inch and larger CRTs are well within reach for people who like (or need) to work at the highest resolution. Buyers with generous budgets and limited desk space can opt for energy-thrifty 19- or 21-inch LCD displays.

Hard drive size

40G to 60GB

60GB to 120GB

120GB and up

Somewhat important. The larger the hard drive, the more data you can store. Most business users don't need a hard drive larger than 20GB, but for mixed use, you'll need at least 40GB. People who work with big databases; spreadsheets; or digital photo, music, or video files should think larger.

Optical (CD or DVD) drive

CD-RW

DVD-ROM/CD-RW combo drive

CD-RW/rewritable DVD combo drive

Somewhat important. All PCs need some kind of drive to read CDs, but more-advanced drives also let you back up files onto disc (with a CD-RW or writable-DVD drive) or watch movies (with a DVD-ROM drive).

Peripherals

102-key PS/2 keyboard and USB mouse

102-key USB keyboard and USB mouse or trackball

USB multimedia-enhanced keyboard and USB optical mouse or trackball

A minor consideration. Some users prefer the newest kinds of keyboards with special buttons for launching their Web browser or dialing up the Internet, or optical mice that never require cleaning, but they aren't essential.
