Graphics card not detected
My motherboard Intel dg31pr and my 450 watt power supply were replaced with the same models as there was no post and then later no power from the Power Supply
So I received a new motherboard and power-supply simultaneously
I installed the motherboard and power-supply. Now everything works, am able to use the computer as before with the exception that the XFX Nvidia Geforce 9400gt video card which was previously working in the older motherboard in the PCIE x16 slot is now not getting detected in the new motherboard PCIE x16 slot. I am using the internal graphics accelerator on the motherboard.
Troubleshooting I have tried -
Tested the graphics card at the XFX Nvidia service center. The card works.
Uninstalled the XFX Nvidia Geforce 9400gt video card driver from the O/S which was installed in the hard drive as I only replaced the motherboard. Restarted and inserted the XFX Nvidia Geforce 9400gt video card into the PCIE x16 slot. Still did not get any thing in device manager or new found hardware. I have two O/S - Windows Xp and Windows 7 both are 32 bit.
All my hardware gets detected -
2 internal hard drives SATA - 500gb and 1.5TB
2 internal DVD drives SATA
1 7.1 Creative sound card
Posts and boots to windows properly
The XFX Nvidia Geforce 9400gt video card gets warm. Power supply fans and Processor fans are running normally. Can anyone help me with on what could be wrong as there is no other DDR2 Video card that I have to check or am doubtful if it could be a power supply issue as all other devices are getting detected and the computer completes POST and boots properly?
