Hello everyone. I have a Sony Vaio VGC-RB38G desktop purchased about 6 years ago. I am looking to upgrade my video card which is a X300 with 128 MB to a newer HD 512MB or 1 GB. Any help or suggestions will be greatly appreciated.
Note : Recently I tried installing a Sapphire HD 5450 , 1GB memory, (P.N. 1000292DDR3L) but no video signal was detected. I also upgraded my motherboard BIOS and uninstalled the old drivers. Still no video signal.
Thanks
