ASUS AH4650 graphics card help

Specs: Windows 7, 2GB RAM 3GHz Processor
For Christmas I got a new computer, along with a ASUS AH4650 graphics card. My computer runs fine without it in, but when I put it in, the fan doesn't spin on the GFX card and my screen stays blank. My motherboard is a G31TM-P21.


1. I was wondering if the fan should spin (It says it requires 400w and I have 350w, but would that make it not spin, or is it just I need the drivers)??

2. There are no Windows 7 Drivers for my graphics card so I tried the XP ones, will it still work with the XP ones, and do you think this is the main problem or Question 1 is the main problem??

It seems to me that you don't have the card seated properly. Reseat it and make sure you fasten it in place with the screw in the bracket. Make sure the 4 pin connector on the card that feeds the fan is plugged in tightly. The 4650 gets it's power form the pci slot itself. Attatch your monitor cable to the outlet of your choice and boot up. The drivers are on the ATI site.

These are for Win 7 32 bit. If your system is different, go to the site and select the correct drivers. Good Luck. Your psu should be ok. It does require 24 amps on the 12 volt rail, but without knowing the specs of your psu, it's a crap shoot.

The HD 4650 is a very energy efficient card. Card manufacturer's tend to go a little overboard with the wattage requirements - better safe than sorry? The HD 4650 only draws about 55W total under full load. That's 20W less than the PCIe slot can supply & only about 4A on the +12v rail. Unless your 350W PSU is complete crap, you shouldn't have any problems.

Make sure the card is fully seated in it's slot. Were there any beeps when you tried it the 1st time?

BTW, you should NOT install any drivers until the card is recognized. And why is it that you don't have the proper drivers if it's a new card? Do NOT use XP drivers with Win7. Download them from the link provided in grasshopper's response.

Thanks guys.

@grasshoper. Thanks, should the fan spin even if I don't have the drivers?

@mickliq. Nope it doesn't beep at all, and the disc I got with my graphics card for drivers doesn't have Windows 7 ones. But I think i've just a found a site with them on

Yes, the drivers have nothing to do with it. It should spin right away to cool the gpu. The drivers are on the link I gave you.

I have 64 bit Windows 7, but the fan still won't spin anyway :( Testing my friends 512 PSU to see if it works with that
