Hi. I recently bought a powercolor ati radeon HD 5450. I plugged it into my motherboard and placed it into my pci express x16 slot. it was placed perfectly..(made a 'click' sound). but when i connected my VGA cable to the card, there was no display. Also,there were no error beeping. the computer booted fine,but it didnt take signal from the external card. i plugged it into the onboard graphics slot and it worked fine.
* I tried disabling the onboard graphics and then connecting the cable to the card.....no joy.:pfff: 
* booting the computer in 640x800 resolution and disabling the onboard graphics...no joy.:( 
* inserting the card, clearing CMOS....still wont take any signal from the card.
The card is not faulty as i took it to the service center and there it worked fine.:ouch: 
* i have a 450 watt local PSU. I know,sometimes local PSUs do not deliver the expected power but my friend has the exact same PSU and it runs a HD 7750 smoothly.
MY motherboard is a bit old,having the intel 945G chipset.i dont know the manufacturer of the board,probably some local vendor.
i also set the 'init graphic adapter' in my BIOS to 'peg/pci'.still,nothing.:??: 
these are details of my BIOS
vendor = American Megatrends Inc.
version = 080014
date = 01/14/2011
ROM size = 512 KB
PLEASE HELP.

Is there a legacy mode that can be enabled?

so you took your card and put it on your friends machine and/or your friend loaned you his to try on yours?.............. something like that would eliminate the pci-e slot as being bad.


also......... exactly what power supply do you have and exactly what power supply does your friend have.................. and don't say 400watt but be specific. they're all not made equal.

The Pci-e slot is fine. I inserted a nvidia 9400 GT and it was detected. regarding PSU,this is what i have:

CIL-ODYSSEY 2012 450W
this is what i found on the side of the PSU:
+5v 34A
+12v 14A
-5v 0.5a
-12v 0.8A
+3.3v 28a
+5vsb 2A
Total 450w..

doesn't matter if your friend has the same PS or not. you should think about trying his.................... but I think yours is a POS and extremely underpowered and should be replaced.

screw the service center where you had it checked. put your card on your friends machine. if it doesn't work the card is bad. return it.

you should take your case to your friends house and try his power supply in your case. try the card again.
