Few Useful Tips to Help you in day to Day Computer Work

Few Useful Tips to Help you in day to Day Computer Work


Protecting your Computer

(i) Before opening your CPU Box ground yourself by wearing anti-static wristband or by touching unpainted metal surface of power supply(CPU should be off) this way you can ground yourself of any static charge you are carrying.

(ii) Close all open drive bays , expansion slots and other opening in CPU to prevent dust from entering into your CPU.

(iii) Don't shake your computer CPU box while it is running , it can cause damage to hard disks or other components also it can cause electric shocks.

(iv) Try keeping your computer away from direct sunlight or places where there is large temperature change like direct path of air conditioner . Keeping computer in direct path of Air Conditioner can cool the computer so much that when computer is exposed to normal air dew might form resulting in short circuits. Also to avoid over heating check that CPU is well ventilated and CPU cabinet fan is working properly.

(v) Do not blow air at computer parts some saliva could inadvertently get into electronic parts and cause short circuit always use use a blower or soft brush to dust it off.

(vi) Check Hard Disk are properly mounted to prevent any data loss due to moving hard disk which can cause bad sectors to develop on hard disk.

(vii) Avoid extreme temperature changes , ensure the room where computer is kept is not susceptible to wide temperature changes , and if you move your PC from cold to Hot place give it time to acclimatize to new temperature before you start working on it.

How to Chose Password

1. While choosing password don't use real words , use both upper and lower case characters in passwords and avoid simple sequence of letters and words and don't use any data from your real life in passwords.

2. Don't use same lo gin id and password for every website you use ,use different passwords and lo gin id in different websites to prevent misuse if someone knows your password in a particular site.

3. Change password frequently , don't use same password for years instead change password every few months

4. Don't save password , most of web browser have feature of saving password if possible turn it off since anyone with access to your computer can log in into your websites with saved passwords .

5. Don't write your password in paper , slips or anything where others can read it , instead try memorizing it use mnemonic to remember passwords.

Uh, have you ever actually built a PC? Have you even taken off the lid and peered insides?

Sorry but I have to debunk some of these myths.I do build PC's and well, some of this is nonsense. Dust from entering onto your CPU? The CPU is covered by a heatsink assembly and fan, and a speck of dust isn't going to hurt it. Dust will accumulate steadily you can't stop that air needs to come into and out of the case to expell heat. In anycase leaving the drive bay open only gains access to the inside of the CD drive.You should always open your case every six months at least and get an air blower and blow some of that dust out you'd be amazed how much collects in there.

Don't shake your box? Why would anyone do that anyway? Hard drives when they're spinning have a gyroscopic effect and don't damage that easily. I've had them sitting on my desktop still connected with the cables and picked them up to move them to put my coffee cup down and you can feel them spinning. Doesn't hurt them at all. Possibly repeated shaking day in day out for months on end may increase the wear on the bearings slightly but who in their right mind would do that anyhow? As for electrical shocks, utter nonsense. The electrics are well and truly sealed in the PSU there are no trailing wires to come loose and short of poking a screwdriver through the ventilation slots of a live PSU you're not going to come to any harm.

You'd have to spit an awful lot of saliva to hurt anything much inside the PC and even then it's unlikely.

See hard drives above.

Unless your PC is already seriously overheating already temperature changes won't affect it, you should only start to worry if your CPU temperature rises above 60 degrees celsius, and graphics cards are usually safe to well over 100, the PC owner owner will be dead long before that becomes a problem.

Cheers.
