Hi, I am currently about to buy a VisionTek - ATI RADEON HD3650 OC 1GB DDR2 PCI Express Graphics Card. Here is the bestbuy link: http://www.bestbuy.com/site/olspage.jsp?...
i know i have a 300w power supply on my comp. but it also says it requires a PCI Express x16 graphics card slot on the motherboard. (I believe my comp has PCI... but I don't get the x16 part)
My motherboard type is an Intel Pentium D 925. Can anyone tell me if this card is compatible with my computer? thanks in advance.
it is an HP Pavillon a1620n
Manufacturer: HP Pavilion 061
Model: RC655AA-ABA a1620n
Answer
Either come back with the computer manufacturer name and model number, or email me it. Have to look the computer up, to see if it has a PCI-Express x16 slot.
PCI, and PCI-Express are Two different technologies altogether.
Plus the slots used for them are physically different.
1.PCI
http://en.wikipedia.org/wiki/PCI_Local_Bus
(PCI slots are always Whitish in color)
2.PCI-Express
http://en.wikipedia.org/wiki/PCI_Express
This info may help explain PCI-Express a little better,
http://www.geeks.com/techtips/2006/techtips-16feb06.htm
EDIT: A PCI-EXPRESS x16 graphics card, WILL NOT work in a PCI SLOT!!
The technology is as different as Night and Day!
PCI is a shared -> PARALLEL Bus architecture, and PCI-Express is a -> Point to Point SERIAL link.

The BestBuy link doesn't work. (Typical of BestBuy! lol! But if you saved this on a wish list, or something like that, it won't let anyone else see it anyway. Or maybe the link just doesn't work for me)
I searched it down, http://www.bestbuy.com/site/olspage.jsp?skuId=8761878&type=product&id=1202650704648
300 watt Psu, an available PCI-Express x16 slot,
plus 1GB of ram memory, are the Minimum System Requirements.
This is the Minimum System Requirements.
Bear this is mind. Although HP indicates you have a 300 watt Psu, it is really only a 210 watt Psu. This is because in 2006, when this computer was made, the manufacturers of Psu's (Power Supply Unit's) didn't have to follow a standard.
Computer manufacturers tend to put in a cheap power supply. Cheap components making up the power supply = cheap cost. Therefore, saving the pre-built computer manufacturer money. This savings (?) is given to the consumer who bought the computer. This, is the bull the computer manufacturer states. In reality, it just saves the pre-built computer manufacturer money, and costs the consumer in the long run.
The power supply's made in 2006, only met 70 percent of the stated Maximum wattage rating. Now they must meet 80 percent, and most Psu's have a higher ratio. Some meet 90 percent of what is stated. SOME, EXCEED the Maximum wattage rating. (Certain after market units)
Not only this, but your Psu is two and a half years old.
(11-Aug-2006) As time goes by, Electrolytic Capacitors inside a Psu break down. This is a normal thing. Designers who use Electrolytic Capacitors know this, and take this into account. They use capacitors that are rated at 50 percent better than needed. As the capacitors break down, they are still at the level needed.
However, now you are going to add a graphics card, that exceeds what the designer of the computers system, has designed. More power than the original design is called for, and the Psu may not handle it, or at least not for very long.
At first everything may be chilly. Then as time goes by, weird things will happen when you play a game. You'll think it's software related, or something to do with your Windows operating system. It won't be. It can be traced right back to that weak Psu.
It is for this reason, that I recommend buying a better, more reliable Psu.
I also recommend, buying 1 more GB of ram. 2GB's of ram, will keep you smiling for a long time.
Games run very smooth with 2GB's of ram.
Now I'm probably gonna' sound like a real bummer, but depending on what games you wish to play, that HD 3650 isn't Even going to cut it!
Better to tell you straight up, then have you find all this out, and think, "I'll never listen, to those answerer's on Yahoo Answers again!"
I recommend an ATI HD 4670, with 1GB of graphics ram, at least.

After the $10 mail-in rebate, it's $85 bucks.
I also recommend this Psu,
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341001
Looks pricey, but after mail-in rebate it's $60 bucks.
Why this OCZ StealthXStream 600 watt Psu?
Because if you keep this Psu at around 118 degrees Fahrenheit, (47.9 degrees Celsius) it can put out 728.8 watts reliably! Your body temperature is 98.6 degress Fahrenheit.
Be aware, that a computer only uses the power it needs, and NO more. If it only needs 100 watts to surf the 'net, it only uses 100 watts. If it only needs 400 watts to play a game, and it is capable of 728.8 watts, it ONLY uses 400 watts!
This Psu has Four 12 volt rails, and 18 Amps (18A) for each rail. You can combine them to equal 72 Amps!
It has,
1.One ->20pin + 4pin ATX motherboard power cable.
2.One ->4pin ATX power cable. (P4 MB) (12 volt)
3.One ->8pin power cable (12 volt)
4.Six -> Peripheral power cables (4pin Molex connector)
5.Two -> 6pin PCI-Express power cables (12 volt) (2X PCI-E)
6.Six -> Sata power cables.
Your computer was made in August of 2006. PCI-Express 2.0 came out 15 January 2007.
Therefore the PCI-Express technology used on your computer is the PCI-Express 1.1 technology.
The HD graphics card you listed, and the one I listed, uses the PCI-E 2.0 technology.
IT'S OKAY!
PCI-E 2.0 is Backward Compatible with PCI-E 1.1!
You won't get the full capability of a PCI-E 2.0 graphics card.
You WON'T NOTICE either!
You may get a frame rate drop of 2 to 4 frame rates. You won't even be aware of it!
http://en.wikipedia.org/wiki/PCI-Express
PCI Express 2.0
"PCIe 2.0 motherboard slots are backward compatible with PCIe v1.x.
PCIe 2.0 cards have good backwards compatibility, new PCIe 2.0 graphics cards are compatible with PCIe 1.1 motherboards, meaning that they will run on them using the available bandwidth of PCI Express 1.1.
Overall, graphic cards or motherboards designed for v2.0 will be able to work with the other being v1.1 or v1.0."

Need computer storage info?
Abby
I've been searching forever for info on Optical, Magnetic, and Solid State storage, but can't seem to find any credible resources.
Here's what I'm looking for:
A definition and simple explanation of each type of storage
List of each type of storage media (not necessarily a LIST, but at least identified)
Typical transfer rates & access times for each storage type
Typical capacity range for each storage type
Typical lifespan of the different storage media
Can anyone provide a reliable source which I can use to find this information?
Wikipedia is not a credible source,
But thanks
Wikipedia is not a credible source,
But thanks
When was this thesis you speak of written? 1994?
Can you guarantee that none of the information within that text is outdated? Just reading the introduction suggests to me that it is.
Please excuse me if I seem lacking in experience; it is because I am.
Answer
you really looked hard huh?
http://en.wikipedia.org/wiki/Computer_data_storage
look at the works sited section for sources.
one links to a thesis by Ann Louise Chervenak who holds a B.S. from the University of Southern California and a M.S. from University of California at Berkeley
that thesis contains much of the information you are looking for. In the 'Magneto-optical Recording' section: "Lifetime of the material is estimated to be at least 8 years"
I'll leave it as an exercise for the reader to find the thesis, it will be good practice for you.
