Updating my graphics card
Very often we are required to update our Graphic Drivers manually.
While Windows Update will update your computer system including the Device Drivers automatically, or the software updaters of your graphic hardware will inform you when updates are available, there may be a time when you may have to on you own update your systems video and graphic drivers, if you are facing issues like Laptop screen brightness flickering or if you wish to get better performance out of your system.
If it has, boot to Safe Mode, then disable the integrated card and enable the n Vidia card.
Of course, your computer may not have an integrated card, but it's worth a check.
Some readers have found that a locked-down BIOS means that even though the fans will spin up on a new graphics card, nothing will appear on the screen. Before you order anything, look inside your case to check whether your current PSU is capable of running a new graphics card.
Remove the side panel and look at the ‘Total continuous power’ figure. If you're going for a top-end card, you may even need 650- or 700W.
Check in Device Manager and see if you have an integrated card and see if it's been enabled.Warning: Even if a graphics card will physically fit and your power supply has enough power (and the right connectors), it may not work.
