Introduction With the popularity of computer gaming video cards are becoming of of the most commonly upgraded components in a computer. However, purchasing a computer video card can sometimes be a very confusing and frustrating task. Before purchasing a video card, keep the below recommendations in mind. Connection Today there are three types of bus (slots) a video card is capable of connecting to. Although with most modern computers today it'll be either PCI-E or AGP. Before buying a new video card make sure you get a video card that will be compatible with the available slots in your computer. PCI-E or PCI-Express was approved as a standard on July 2002 and is the latest computer bus found in computers. PCI Express is designed to replace PCI and AGP and is available in several different formats: x1, x2, x4, x8, x12, x16 and x32. See our PCI Express definition for a full description and related links. AGP or Advanced Graphics Port, is a new standard available on Pentium II and later motherboards. Introduced in 1997, AGP is a 32-bit Bus designed for high demanding video cards. AGP has a direct line to the computer memory, which allows 3-D elements to be stored in the system memory instead of the video memory and is available in three different standards (1.0, 2.0, and 3.0). See our AGP definition for a full description and related links. PCI or Peripheral Component Interconnect, was first introduced in 1992. Although still in use most computers today will have an available AGP slot and should be used instead of PCI. See our PCI definition for a full description and related links.
See document CH000258 for additional information about determining the type of video card you're using including the BUS type.
Power supply Today's video cards are one of the must power hungry devices in your computer. Make sure that your power supply will meet the requirements of your video card. Many video cards will require a 500W or more power supply. If your computer doesn't meet the power requirements you'd need to upgrade the power supply before being able to install the new video card.
Additional information about determining what type of power supply you have and how many watts it has can be found on document CH000800.
Memory Another important consideration when purchasing a video card is the amount of video memory the card has. Like system memory, the more memory located on the computer video card in most cases the greater capability of the video card. Today we suggest at the minimum a video card with 256MB of video memory. Other considerations Below are some additional considerations you may want to think about when buying a video card. Ports - Many newer video cards will only have a DVI connection or both a VGA and DVI connection. If you're using a video card with a monitor that has a VGA connector it can still be used, but you'll need to also purchase a DVI to VGA converter if not included with your video card. Chipset - There are dozens of different video card manufacturers. However, there are only two major chipset manufacturers; Nvidia and ATI. Although both are great manufacturers there can be great big differences between the two as far as performance. Before buying any video card it's a good idea to look up a hardware review on the video card before purchasing it if you're concerned about it's performance. Size - If you have a smaller computer case fitting some of the new video cards in the computer many not be possible. Video cards today are much larger than older video cards because of their increased capabilities and need for cooling fans. Make sure your case is going to have room for a new video card. The only way to do this is to open the case and physically look. Warranty - How long is the warranty and what does it cover. Support - Is the technical support number a free number and is it open 24 hours, 7 days a week? You can find contact information for all major video card manufacturers on our video card contacts page.
Price range The price range can vary depending upon the type of video card purchased, amount of memory, the interface used, and the available options. In general prices can range from $100 to $500 USD. Where to purchase For best price we often recommend that users purchase all computer hardware online. You'll be able to look at other customer reviews and get a much lower price. If you're uncomfortable buying online or want to talk to a sales rep you can always visit a local retail store and then buy online. See listing of places to buy computer hardware.
Just make sure that the MAX OUTPUT that should be on a sticker with all the other information directly on your power supply is the minimum output that you require on your new purchase of an ATX power supply. Your options for replacement don't really rely on the brand of power supply, it's determined more by what your power consumption is - so a good rule is to at least get one as powerful as the one you're replacing. Also make sure that the new power supply has the appropriate power connections and the amount that you need, but the outlet in which you purchase your power supply will be more than happy to give you information about all the power supplies that they have for sale.
Most modern power supply units are of the ATX type. Brand should not matter. Your PC used a 300 watt power supply when new. You can purchase a power supply with more output (watts) if you like, but not less. You will have to purchase from a computer specialty store most likely - take the dead one in and compare it side by side with the new one before buying.
If you plug the supply in and press the wire leading into the plug you have just put into the Laptor in towards the plug does the power light come on
Or if you move the cable up and down or left to right does it come on.
Most time the wire breaks just as it enters the plug top and this can be repaired by a competant shop
You really need to have someone with a voltmeter check out if there is a supply at the computer plug before your buy a new one
The outer of the plug is negative and the inner positive , set the meter to read around 100vdc .
If you find there is no voltage then it will cost $20 from
I went to a local computer store and purchased a new mother board which is all I needed to begin with but no one was willing to tell me how to get one without a charging me for the information on how to purchase a mother board from your company. but thank you anyway.
Another option you have, would be to purchase an external enclosure for the hard drive and it would then connect via USB cable. These enclosures are usually about $30, and the device works quite well as an external drive as long as you have USB 2.0
This would enable you to access all the information on that drive *and* you could use it as a backup drive for your main hard drive as well.
Altec no longer makes the power supply. However you can find used ones on eBay for about $25. I went to my local electronics store and bought an 18V, 2 amp power supply for $14. It works great and charges the iPod just like the OEM power supply. The store I purchased it from is JK Electronics in Westminster, CA 714-890-4001.
