hello(sorry for my english),i try to upgrade a old system,i start with a old motherboard msi ms-7254 and i try to add 2 gb RAM,Intel pentium D 925(3.0Ghz),and a graphic card nvidia 8800gtx,my big question is if the graphics card is compatyble with moteherboard(for moment the system no want to start whit the graphic card,pc working but the monitor show me no signal,if i take of the graphics card,happy days,working,,,,,any answer?i try to swap the RAM,or with just 1Gb ,buth stil no working...many tanks

A couple possibilities...
1) the PSU is too weak or too cheap for the 8800 GTX. What is the model you have?
2) you forgot to move the monitor's cable from the integrated video port to the graphics card's port.

You really need more RAM than 1GB, so hopefully that isn't the problem. Try the computer again with just the original RAM.

the original RAM is 512RAM,,the psu is Alpine JSP-500P12P(500w 30 A) i buy special for this graphics card,and i connect the monitor whit dvi adaptor to hdmi

If a take of the graphic card,the system work perfect,,,

Does the computer start with the gfx card in and the new RAM removed?

 

[Bobosca]

no
I look on ebay to buy another motherboard,because i try to found on internet if the motherboard is compatyble with the graphic card but nothing

Do you know for sure that the old 8800 GTX is working? Maybe it is defective.

i dont now 100%,but the cooler working,and when i start the system is one long beep and 2 short(the cooler workin and if i dont plug the two 6pin socket have a strange noise so,i think working)

 

[clutchc]

Those beeps is an error code. If you have an Award BIOS...

1 short - System boot successfull
2 short - CMOS setting error
1 long 1 short - DRAM or M/B error
1 long 2 short - Monitor or display card error
1 long 3 short - Keyboard error
1 long 9 short - BIOS ROM error
*repeated beeps - DRAM error
*repeated short beeps - Power error
*Repeated high & low beeps - Processor is damaged/Overheated
