Hi Everyone, I'm a Newb here so maybe humor me a little...Here's my dilema

I bought a GeForce Nvidia 7600gs PCI - Express Video card for my dell 4700 b/c I'm tired of the crappy intregrated video that comes with this dell. Before I installed the actual card I installed the drivers from the CD that came with it.

I also made sure my BIOS video setting was set at "AUTO" rather than "INTREGRATED."

I then installed my actual video card into the PCI Express slot. I then plugged my 17 in LCD monitor into the card itself and turned on the computer.

The computer turns on and loads up BUT I'M NOT GETTING A SIGNAL TO MY MONITOR. It's just a blank screen. I can hear the card working too b/c the fan is on.

Why isn't my card sending a signal to my monitor to turn on?


Things I've done:
- Plugged the monitor into the integrated while card was installed - it told me to new video card detect and please shut down and plug monitor into card.

- I did so and computer loads up shut monitor doesnt get a signal so I cant see anything

- Disabled integrated drivers but still nothing



What is my cards problem. It turns on(I can hear the fan) but it doesnt send a signal to my monitor.

Maybe my power supply is strong enough? Do I have a bad card? Am I not doing something?

First – Try reseating Video Card – Sometimes all of the pins/contacts are not all aligned properly –

Secondly – Verify that you are using the correct PCI Express Slot –

The Power Supply appears to be marginal – See Specifications below – SEE – Proprietary Manufacturer – NOTE below -

That depends on what 7600gs PCI - Express Video card are you using – there are several models – It is probably marginal -
http://www.evga.com/...7 Series Family


(1) – Dell 4700 – Stock Power Supply - Specification
The 305-W power supply can operate from an AC power source of 115 VAC or 230 VAC at 50 - 60 Hz. The power supply provides
+12A VDC @ 18.0 AMPS*
+12B VDC @ 18.0 AMPS*

* Maximum +12A and +12B VDC output (up to 19.0 A) will not exceed 15 seconds in duration. Under this condition, tolerance on the +12A and +12B VDC output, may be +/- 10%

(2) – GeForce Nvidia 7600gs PCI Express Video Card Specification

http://www.evga.com/...7 Series Family

Depending on what 7600gs Video Card Model you are using – whether Dell Power Supply is sufficient [??]
I believe that it is probably marginal -

NOTE – Dell is a – Proprietary Manufacturer – Which means they do not follow – The PC Standards – The Dell Power Supply & Motherboard – Do not follow PC Standard Wiring – Therefore you must use a – Dell Certified Replacement Power Supply – whenever replacing.

I do not know if Dell Motherboard is a – PCI Expressฎ compliant motherboard. The power track wiring may not be PCI Standard – Dell is a – Proprietary Manufacturer – Chances are – It is not –

Ok so I probably found out what it is....my Dell 4700 stock power supply is 305 watts.

My EVGA nVidia 7600 GS w/ fan requires minimum of 350 watts.

New Problem....DOES ANYONE KNOW A POWER SUPPLY STRONG ENOUGH THAT IS COMPATIBLE WITH MY DELL 4700?????

The only place you can buy a dell specific power supply is from dell. I ran into the same problem with my old Dell dimension 8100, I upgraded everything I could cpu,ram,hdd, video card, sound card. Started having problems found out my power supply is insufficient, found out it was a proprietary power supply. Went to the dell website a new dell PSU with enough power to supply what i needed it to do was like $300+. [bleep] Dell, after i did all that, spent all that money and I cant upgrade the most simple part of a computer, pissed me right off, so much Ill never recommend another dell to anyone. You HAVE to buy a DELL PSU. Unless, youre very good with electrical stuff then you could buy a regular ATX PSU, cut the connectors off of your dell unit and painstakingly rewire the connectors to work. And then it still might not work properly. Just my insight into Dell products.

Here's a 470 watt power supply that claims to be compatible with the Dell 4700.

http://www.pcpoweran...l.htm?show=S47D

I am keenly interested in whether the power supply upgrade works for you. I have a similar problem with a 4700 and an ATI Radeon X700. I eventually discovered that if I start from a cold machine, then cycle the power switch every few seconds, I can tell when the card is recognized. The GPU fan starts out full speed and then quickly drops down in pitch when it's successful. It sometimes takes 20 cycles to work. Needless to say, this is unsatisfactory, and I leave the system on around the clock.

Best thing to do is to go to the Dell website and look there for a compatible power supply :whistling:
