I have bought a new Sapphire Radeon 5450 512Mb graphics card for my pc that i have just upgraded. However when I install it into the PCIE2 slot on the mobo the computer fails to boot. Instead the CPU and case fan go to maximum and stay like that without any output. The computer has a 250w PSU with 12v-14a but when i tried it on an acer pc with a 250w 12v-15a PSU with a PCI X16 slot it worked perfectly. Could someone please say why the pc fails to boot windows.
Cheers everyone.
