I recently received a "new" GPU, a BFG Tech GeForce GTS 250, replacing older 9600GT. After deleting drivers and installing the GTS 250, PC runs fine and I've installed latest drivers, after the normal restart PC boot normally, but after the Windows 7 loading screen the screen goes black and the "no signal" appears on the monitor and nothing else. I tried everything I can, replaced the PSU with 750W Chieftec, reseated all cables, RAM and video card, cleaned GPU heatsink, replaced thermal paste, installed older drivers, installed Windows 7 auto-driver, fresh Windows install, tried every BIOS settings linked with PCIe. Could be video card failure or motherboard compatibilty issue?

Current PC specs:
Mobo: ECS P4M900T-M2
CPU: Intel Core 2 Duo E7200
RAM: 1GB Geil + 2GB Kingston DDR2
HDD: 1TB Seagate + 320GB WD
GPU: current 9600GT
PSU: Chieftec Turbo CFT-750-14c

(1)
make sure your connetion cable is pugged into graphics card not mobo

(2)
start your computer in safe mode.
to do this keep tapping F8
if it asks you to choose a boot disk choose the one with windows installed on it hit enter
then quickly alternate between hitting f8 and the Esc keys

if the problem persists and doesn't go to safe mode go to number (3)

once your windows boots up it is in safe mode and should be displayed. log in and right click on the desk top click on screen resolution. then choose the display that you want to look at on boot up. then check the make this my my main display.

(3)
Take out the graphics card and re-seat it (i don't think this will do anything because the windows logo is showing up but least difficult and time consuming to most and all right)

(4)
put your windows installer disk in boot into mobo bios then choose that to as your boot up.
format your os partition and reinstall windows from scratch and then your updates then your drivers (have a long day if its windows 7 or older) and if this is not kewl because you didn't make proper partitions i'm sorry that you are losing your data

Thanks for answering, unfortunately none of this worked, I've tried it with 2 windows installs on each hard drive.
I'm thinking that:
1. the BIOS/Mobo is to old (latest version installed but it's from '08)
2. Video card BIOS is messed up somehow
3. Video card not sending analog signal after Windows loads, forgot to mention that I'm using DVI to VGA adapter because my monitor is VGA only (tried 3 different adapters)
