Hi, recently i have installed a Zotac Geforce GTS 450 into my HP hpe-490uk. After installing all of the necessary drivers i restarted the computer as prompted to and can now no longer access my desktop. After the 'starting windows' screen after the first bootup screen nothing happens and my monitor just loses connection with the PC. I also managed to wipe the computer and put the PC back onto its factory defaults with no help but being unable to access the PC as soon as I restarted again. I think it would also help if I mentioned that the screen only shows up in the middle of the screen on a small box. Thanks Shabazz

check in the bios what the first boot device is. it may be that the windows is switching over to the oboard video as the first video device. also as you can see here with the almost same card make sure the 6 pin pci power plug is plugged in you may have to use the 6 pin to molex adaptor on your old power supply.

the other issue is the card may be pulling more power then the 12v line can give.

Hey, well i've recently uninstalled the drivers for the card and the pc seems to turn on now and boot up to desktop. Albeit the ugly graphics. Ive also checked the 6 pin and that's plugged in. Ill give BIOS a check now :)

Also checked the BIOS and the Primary video adaptor is set to pci-e

check to see if there any mb bios updates..i tried to find some and did not. i would try another brand of video cards...it may be your card is bad or the mb and that card may not want to work together or the card pulling more power then the power supply can output. look at the wattage of the ps (max) and 12v line. you may have to drop in a 620-650 video card if it a 300w unit. or a low end amd card.
