4. Cek BIOS pada boot order.
5. Khusus Windows 2000/XP, jika konfigurasi hardware berubah, boot dengan boot disk. File boot ini mungkin perlu diedit. Read more…
User’s guide to avoiding virus infections
Keeping an eye out for viruses
Computer viruses are everywhere! This guide will show you how to stay alert and how to avoid getting infections on your computer. Having an updated virus scanner is only a small part of this, there are many ways that you can prevent having viruses other than a virus scanner, as it will not always save you.
Types of viruses
There are many type of viruses. Typical viruses are simply programs or scripts that will do various damage to your computer, such as corrupting files, copying itself into files, slowly deleting all your hard drive etc. This depends on the virus. Most viruses also mail themselves to other people in the address book. This way they spread really fast and appear at others’ inboxes as too many people still fall for these. Most viruses will try to convince you to open the attachment, but I have never got one that tricked me. In fact, I found myself emailing people just to make sure they really did send me something. It does not hurt to be safe. Read more…
If you don’t want to spend big bucks on a new PC, consider upgrading your old system’s motherboard and CPU. This can boost the machine’s performance and give you access to the latest technologies. It can also save you hundreds of dollars.
What you won’t get is a new hard drive, optical drive, or operating system, though the new motherboard gives you the option of upgrading these components later. When you do it yourself, you choose the make, model, and cost that serve you best, rather than settling for what’s preloaded in an off-the-shelf machine. Read more…
Beep Code Manual, Better Than Gold Techies, American Megatrends Int. & Phoenix
(I’m IT, I use these codes to trouble shoot hardware issues at my job. Enjoy) cold.gif
BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system’s hardware, checking to make sure that all of the system’s hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix. Read more…
10 reasons why PCs crash U must Know
Fatal error: the system has become unstable or is busy,” it says. “Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications.”
You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?
1 Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:
* Start-Settings-Control Panel-System-Device Manager. Read more…
