I just bought a nvidia geforce 7800GS OC, and can't seem to get it to work. I put it in and plug the power cable into it but when I turn the computer on nothing happens on my monitor. The fan and blue light come on but thats about it. Here are my specs.


Dell dimension 4600

Intel Pentium 4 CPU 2.40GHz
1.75GB RAM

Larry,

Make absolute sure the power is connected. Did you hear a double beep?


You may want to check how much of a power supply you need for the card. I noticed in my wanderings some cards require up to a 550 watt power supply. It should say on the box.

your power supply may not handle that card.
My 400watt ps would boot but hung in AH bad, You need a bunch of amps on the 12vdc rail for that card to work right. See this thread

I assume if you put the old video card back in, all is well?

It says it needs a minimum 400W. I just bought the power supply from dell. They have higher watts so I might just send it back and get a better one. Thing is that on the power supply itself it says max output is 385W. It also says I need a AGP 2.0 or higher but I dont know how to check if my motherboard has one. I get paid tuesday and wanted to get a new motherboard and hardrive anyways to complete my system upgrade.

So what do you guys think I should do? Another question what MB, PS, and HD do you guys think I shuld get?

I'm no expert, but I went with an Asus M2n and an AMD 6000. I also suggest at least a 600 watt power supply probably more. In the BBS I noticed that Western Digital got a nod. I bought one of those too. It was 70 bucks for a 250 gig drive and please I beg you to get an excellent heatsink and fan. Can't tell you how they work because they haven't arrived yet. I ordered them yesterday. The status is they have already shipped.

Okay I found the problem my MB only has 533MHz bus speed the card needs atleast 700. I'm going to just go ahead and buy a 600+W supply, but I need help finding a motherboard. I need one with a minimum 700MHz bus speed, with an AGP 2.0 slot or higher, and it has to be "AGP compliant" so the BFG card can fit in it. I'm looking to spend around 300 for it if anyone has any info thanks.

You can probably find an AGP but they are phasing out fast. PCI-e is the in thing.

I just purchased an Asus mb but I haven't received it yet. I'm anxiously tracking it ont the UPS website ......Every 15 mintutes. It hasn't been updated since Saturday morning (Darn it).

I've heard Abit is decent too.

btw, I'm stuck with an AGP 512 BFD card and waiting for an asus PCI-E card that is accompanying my mb.

I'm not sure how many options you'll have for an AGP VC anymore. I took a quick look on newegg. I might have missed something since I couldnt even search by AGP vs PCI-e anymore...

Here's the only one I saw that would seem to fit your needs...and thats just a guess based on what you typed.

I found this one:

http://www.l-trondirect.com/aimb-542ve-00a1e.html


It has 4x 184pin DDR slots and a AGP 8X slot that I need. Its just that the bus speed says 533/800MHz and I dont know what that means. I need 700MHz to run my card. I just dont know if its 533MHz or 800MHz. If its 800 them I think I found my new MB. Can anyone clear this up?

Just think of bus speed as MB ability to allow the processor to move data around..

Quote

 Front Side Bus (FSB) - The Front Side Bus is the most important bus to consider when you are talking about the performance of a computer. The FSB connects the processor (CPU) in your computer to the system memory. The faster the FSB is, the faster you can get data to your processor. The faster you get data to the processor, the faster your processor can do work on it. The speed of the front side bus depends on the processor and motherboard chipset you are using as well as the system clock. Read on for more information about the Front Side Bus later in this article.


Here is the link to the article which might clear things up for you...

http://www.directron.com/fsbguide.html

There is also a link on PCI-Express, that may be worth looking at as well...



Quote

If your processor has a ... FSB then the system clock speed should be:

66MHz (Various Celeron and older): 66MHz clock
100MHz (Pentium II / Pentium III / K6): 100MHz clock
133MHz (Pentium II / Pentium III / K6): 133MHz clock
200MHz (Athlon, Duron, Thunderbird): 100MHz clock
266MHz (Thunderbird, XP): 133MHz clock
333MHz (XP): 166MHz clock
400MHz (Pentium 4): 100MHz clock
400MHz (AMD XP): 200MHz clock
533MHz (Pentium 4): 133MHz clock
800MHz (Pentium 4): 200MHz clock
800MHz (AMD64): 200MHz clock
1066MHz (Pentium 4/LGA775): 266MHz clock
1333MHz (Pentium 4/LGA775): 333MHz clock


Now, remember what I said about the processor multiplier earlier in this article? (Processor speed = processor multiplier x system clock)

If you do not know the multiplier for your processor simply take the proper system clock speed for it and divide that into the rated processor speed and then round the dividend to the nearest .5. Examples: The Pentium4 3.06GHz processor has a FSB of 533MHz. Its system clock is 533 / 4 = ~133. The multiplier is 3,060 / 133 = ~23.

The AMD Athlon XP2700+ has a main clock speed of 2.17GHz and a FSB of 333MHz. Its system clock is 333 / 2 = ~166MHz. The multiplier is 2,170 / 166 = ~13

Where did you get that 700Mhz spec?


[EDIT]

also note that the Intel Pentium 4 CPU 2.40GHz you listed does not support an FSB of 800mhz so buying a new MB alone that supports an FSB of 800Mhz will not mean you will have 800Mhz FSB...

[EDIT2]  I would reexamine the power supply first before buying anything else.

Will I have to buy a new processer for that MB or can I just install it and start playing?

Here is the v card that I got.

Ok I see.... the processor speed needs to be 700Mhz or higher not the BUS speed....


Well according to those specs your system should be good, other than maybe the power supply...   I would take a closer look at the power supply before doing anything else.

[EDIT]
How old is your existing MB?

The specs also list this--->
>>An available AGP 2.0 slot or higher

Which your MB may not support ...
