lacfiremx02 · 01-21-2008, 01:56 AM

I just bought a new motherboard and processor and video card today.
Everything works fine accept my pci-express video card. My pci ati radeon 9250 works fine but for some reason the geforce 7900 will not work when i put it in and turn the computer on.. It just says no signal on the screen.. Thanks if you can help it would be appreciated.

lacfiremx02 · 01-21-2008, 09:29 AM

yeap its plugged in

dai · 01-21-2008, 11:16 AM

it pull 3x the power of the ati,did you check you had enough power to run it before buying it
usually when you upgrade the video card you also upgrade the power supply

You need to cheak overheating.And mobo/vide combatibility it might not be the right PCI slot

Can you please post your specs too? Download and install PC Wizard from my sig. Open it and go to FILE, SAVE AS, and save the text file on your desktop. Then copy the contents of that file into this thread. cheers.

it says memory allocation error when i try and run that PC wizard program

**FreoHeaveho** · 01-22-2008, 02:40 PM

How much ram do you have installed?

lacfiremx02 · 01-22-2008, 03:12 PM

4 gigs

**FreoHeaveho** · 01-22-2008, 04:07 PM

Assuming your XP is 32 bit, you have 4GB of RAM plus the onboard ram on the graphics card. Take out 1GB or more and i am sure that will sort out the memory thing. A 32bit operating system (windows xp 32bit) can only address 3.2GB (including graphcis).

Take out 2GB to be sure (assuming it is 32Bit Windows)

Then restart your computer and post the PC Wizard text.

Im going to bed now, but in the meantime, (if PC Wizard works), try the 7900 card again. I think it will work with the ram removed. Remember, add up the graphics card and the ram memory capacity, and dont exceed 3.2gb for a 32 bit system.

I just had to go directly to the website and download PC Wizard and it worked

**FreoHeaveho** · 01-23-2008, 07:06 AM

As i said. Take out 2gb and try the card. I think that i will fix the issue.

lacfiremx02 · 01-23-2008, 08:17 PM

can i ask how though?

**FreoHeaveho** · 01-24-2008, 03:28 AM

Remove one stick of ram. Let me know if you need help, but essentially, there will be two white levers on either side of the ram modules, press firmly down on each side (with the computer off) and the ram will pop out. Leave the other one in and try the 7900.

lacfiremx02 · 01-24-2008, 04:59 AM

Still doesnt work

**FreoHeaveho** · 01-24-2008, 06:07 AM

Try the card in a different machine to ensure it works...

lacfiremx02 · 01-24-2008, 05:18 PM
