Computer Buying Tips


Tips in buying computers

1. What should I buy? Branded or non branded computer.
Branded computers are known as quality products. They are manufactured under certain standards and quality control methods. But the disadvantage is the high price. In the other hand non branded PCs are low in price but cannot guarantee the quality. Whether if you buy branded or non branded following details will be help you to make a decision easily.

2. Warranty

I consider this as the most important of all computer buying tips. Every new computer should carry minimum 1 year warranty for parts and labor. Please check the warranty period and conditions carefully before purchasing a computer. Some suppliers provide additional years of warranty with an additional charge. My personal advise is to go for this extended warranty. Its worth.

3. Supplier

Always buy from a reputed supplier. Don't buy from small shops just to save few dollars. Most of small computer shops are using cheap quality parts. Also you will be in trouble in getting warranty if they close down shops within one year.

4. Software license

You may get operating system and few additional software packages free with your computer. Please check whether they are licensed copies and you should get all documents related to license.

5. System configuration

Think what kind of work you are going to do with your computer. Most of the users are purchasing computers to browse Internet. Then an average PC with 256MB memory, Pentium IV CPU, 64MG graphic card, 20GB Hard drive will be enough. But if you are going to use powerful games etc then go for 1 GB memory, 128MB or more VGA, 88GB + HDD

6. Internet / Networking

How are you connecting to the Internet? If you're using a high speed Internet connection, such as cable broadband or DSL, you'll want to make sure you have a network card built into your system. If you have a wireless network at home or at the office, save money and installation time by buying the wireless card built right into the computer.

7. Monitor

Monitors have different sizes and types such as 17", 21", flat screen etc. Don't go for 21" screen unless you are a graphic designer or CAD operator. The price difference between 17" to 21" is very high. Flat (slim) monitors are easy to use and looks good. Don’t throw away your monitor if it's still working properly. Instead, keep it and save a chunk of money by just replacing your old CPU [computer tower]. Monitors last much longer than CPUs and the technology is usually compatible between your old monitor and the new CPU. However, if you’re dissatisfied, then monitors, keyboards and mouse are the three tools to spend extra money on, since you use them every day!

8. Operating System

Always ask for the latest Operating System

Unable to install a pci graphics card


Does your tower support PCI?   Is the card PCI, and not PCIe?  (There's a big difference)
If you've installed the drivers and software that came with the video card, and still get no picture, you may have a defective product.  However, try this, to rule that out.
Once in your PC, and your monitor's connected, try the "Source" button on your monitor. It's possible that your old video card used analog, and your new one uses digital, and your monitor just needs to look at the right input.
If that doesn't work, and you've installed the software, you may want to contact Radeon to replace the unit. Or, return it to the store to exchange for a new one, if you're within your return period.

More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected and connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card are inserted correctly and didn't "pop-up" due to vibration.
System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on. PROBABLE CAUSE DIAGNOSIS SOLUTION
Power cable is unplugged. Visually inspect power cable. Make sure power cable is securely plugged in.
Defective power cable. Visual inspection, try another cable. Replace cable.
Power supply failure. Power cable and wall socket are OK, but system is still dead. Contact technical support
Faulty wall outlet;circuit breaker or fuse blown. Plug device into socket know to work and test. Use different socket, repair outlet, reset circuit breaker or replace fuse.



System inoperative. Keyboard lights are on, power indicator lights are lit, and hard drive is spinning. PROBABLE CAUSE DIAGNOSIS SOLUTION
Expansion card is partially dislodged from expansion slot on the motherboard. Turn off computer. Take cover off system unit.
Check all expansion cards to ensure they are securely seated in slots. Using even pressure on both ends of the expansion card, press down firmly on expansion card.
Defective floppy disk drive or tape drive. Turn system off.
Disconnect the cables from one of the floppy drives. Turn on the system, check to see if the keyboard operates normally. Repeat until you have located defective unit. Contact Technical Support.
Defective expansion card. Turn computer off.
Remove an expansion card. Make sure expansion card is secure in expansion socket.



System does not boot from hard disk drive, can be booted from floppy disk drive. PROBABLE CAUSE DIAGNOSIS SOLUTION
Connector between hard drive and system board unplugged. When attempting to run the FDISK utility described in the HARD DISK section of the manual you get a message, INVALID DRIVE SPECIFICATION. Check cable running form disk to disk controller on the board. Make sure both ends are securely plugged in; check the drive type in the Standard CMOS Setup (in your motherboard manual).
Damaged Hard Disk or Disk Controller. Format hard disk; if unable to do so, the hard disk may be defective. Contact Technical Support.
Hard Disk directory or FAT is scrambled. Run the FDISK program, format the hard drive(See HARD DRIVE section of manual). Copy your backup data back onto hard drive. Backing up the hard drive is extremely important. All Hard Disks are capable of breaking down at any time.

Reformat the Hard Drive as described in the Hard Drive section of the manual. Re-install applications and data using backup disks.



Error message reading "SECTOR NOT FOUND" or other error messages indication certain data is not allowed to be retrieved. PROBABLE CAUSE DIAGNOSIS SOLUTION
A number of causes could be behind this. Use a file by file backup instead of an image backup to backup the Hard Disk. Back up any salvageable data. Then do a low level format, partition, and high level format of the hard drive( see Hard Disk section of your manual for instructions). Re-install all saved data when completed.



Disk formatted on IBM PS/2 will not operate with this system. PROBABLE CAUSE DIAGNOSIS SOLUTION
The IBM PS/2 uses a different format than other computers. IBM PS/2 disk format will not work in an AT type computer. Format disk in the AT type computer insert disk into the IBM PS/2 and copy the files you wish.



After install an expansion card (network card, tape drive card, etc.) the system no longer works properly. PROBABLE CAUSE DIAGNOSIS SOLUTION
No power to monitor. All or part of the system may be inoperable. The new card may work but a mouse or COM port may not work. Change the interrupt or RAM address on the new expansion card. See the documentation that came with the new card in order to change pin settings. many expansion devices come with proprietary software that will assist you in doing this.

    1. Check your Keyboard-Video-Mouse (KVM) switch. If the system is connected to a monitor, mouse, and keyboard through a Keyboard-Video-Mouse (KVM) switch, or console selector switch, then disconnect the switch and connect monitor, mouse, and keyboard directly to the system. If this solves the issue, please contact your switch manufacturer for support and compatibility on the switch. Some switches can have a firmware update applied to resolve common problems.

      Note: BladeCenter Telco chassis - The KVM module contains keyboard port, mouse port, Power LED, Location LED, Critical Telco Alarm LED, Major Telco Alarm LED, Minor Telco Alarm LED and a video port. The PS2 keyboard and mouse connectors are standard 6-pin Mini Din. The Telco alarms mirror the Telco alarms located on the front panel of the media tray because they use the same signal lines. The KVM module allows the connection of a VGA monitor for system maintenance and control. The video connector is a standard 15-pin VGA. The KVM module is hot-swappable. It is docked into an edge card connector located on the backplane:

      migr_40293_4.jpg

    2. If you have your system daisy chained for KVM capabilities using the C2T port (e.g. xSeries 330),
      then you must flash the C2T firmware after flashing the system BIOS, in order for the mouse and keyboard to work. Otherwise, after a BIOS flash, you will lose keyboard/mouse capabilities unless you walk up to each machine and push the select button.

    • If you are using NetBAY Advanced Connectivity Technology (ACT) CAT5 cabling in your rack server, instead of KVM cabling, click here for ACT information.

    1. Check for POST/startup errors. If you are getting a POST/startup error on the keyboard and/or mouse:

    2. Verify that all items are firmly connected to the correct ports, and that the cables are undamaged with no bent pins. The PS/2 style mouse and keyboard ports look identical, but are not interchangeable. The mouse and keyboard must be attached to the correct ports in order to be recognized by the system and to function correctly.
    3. Swap each item for known good units. If a new item works where the original did not, then the original component must be faulty.

    4. If the keyboard works during the POST/BIOS screens, but not in the operating system, check software logs for device driver errors. Contact your software vendor for more support in configuring the I/O devices.

    5. Check the F1 Setup error logs for system component failures or errors. These are found under Event/Error Logs. Troubleshoot suspect components further to determine if the hardware is faulty. If an IBM component is determined to be faulty, please contact your local IBM Support Center for warranty replacement of the part(s). Please have the Field Replacement Unit (FRU) / Customer Replacement Unit (CRU) part number and Machine Type, model and serial number ready.

    1. Run hardware diagnostics. Replace any parts found defective.

    1. fw.gif
    Download the latest diagnostics for your system
    1. If you can down the system, check the keyboard cable connector on the system unit for proper voltage.

    2. Power off the system.
    3. Disconect the keyboard cable form the system unit.
    4. Power on the system and check the keyboard cable connector on the system unit for the voltages shown:

      PIN Voltage (Vdc) 1 +5.0 2 Not used 3 Ground 4 +5.0 5 +5.0 6 Not used
    5. If the voltages are not correct, replace the system board. Otherwise, replace the keyboard.

    6. If these steps have not solved your problem:
