Hi, recently I decided to upgrade the motherboard and graphics card in my computer. I also got a new case because the new motherboard did not fit in the old one, so I transferred all the hardware from old to new, matching slot to slot. I have read all the manuals of the graphics card and motherboard, but no info on my problem.

My problem is, when I turn my computer on, all the LEDs and fans work and the HD seems to be whirring and everything seems to be working fine, and the LEDs on the back, appear to say (according to the guide in the manual) that the BIOS is up, which I think is perfectly normal.
But there is no display on the screen, it acts as if there is no input from the computer and goes into standby.

The screen works fine, I have tried it on a different comp, and tried a different screen on my comp, with the same result.
I have not had the oppurtunity to try the graphics card in a different computer yet though.
The fan on the graphics card is working fine, so power to the card seems to be OK.
I don't know what could be the problem, but it is (obviously) to do with the graphics card.
I have:

MSI 865PE Neo2-P Motherboard.

Radeon 9600 Pro 256MB (AGP8X) Graphics Card.

1 x stick of 256MB DDR PC2100 RAM and 1 x stick of 512MB DDR PC2100 RAM

a 40GB Hard Disk

a P4 2.1Ghz (Or thereabouts)

and an Antler Supercase and 330W ATX Power Supply

If anyone could solve my problem that would be great, but keep it simple, I don't understand alot of the computer language, and you'll just confuse me.
Thanks!

are you getting the LED array that means 'BIOS SIGN ON'?? 1=Green 2=Red 3=Red 4=Green?? As I understand it, whichever array the LED stays on, is where the problem is. So it could indicate a BIOS fault, if thats the array you are seeing. Go to the MSI UK page, then click support, and then go to the forums to see if anyone else has had the problem.

btw, is your cpu a northwood??

also you do you not hear beeps? they give you a rough idea of what the problem is. i have just done something similiar to you and i was getting no display. when i turned on machine i got a long beep then 3 short ones. apparently that refers to the graphics card. i got a cheap replacement and it has been fine ever since. the old card had been working so i presume i have done something to it while it was being stored.

I recently found out that I have a willamette CPU, an old model which is not compatible with my new mobo, looks like I better get out and buy another CPU and RAM.

Yeah, the cpu definatley wont work with that board, but your pc2100 ram is compatable with the board. if you really think the ram is a problem after youve got a new CPU, only then should you change it.
