ever since i got a 27" monitor, things take longer to execute. i guess i need more memory, but i'd like to ask if you all think that's where my problem lies.

windows xp home
2.8ghz celeron
1.25 gb ram
virtual memory 5000min/5000max
__________________________
nvidia 8600gt with core clock....540/memory clock....700/shader clock....1190

the computer accepts 2gb ram. should i upgrade the memory and vid card,,,or is the processor not strong enough?

thx

Exponential. The word.

The word that we need to use here is exponential. You didn't reveal what your old display was but let me guess it was set to 1024x768.

At new 27 inch could be (you didn't say) at 1920x1080 so lets see how many pixels the computer used to manage and how many now.

There actually 3 dots for each pixel and in 32-bit color that means that each pixel of RGP uses 32 bits or 4 bytes. We're ready to figure out the numbers before and after.

How much video memory would have to be cleared for a clear screen before and after?

Before: 3,145,768 bytes (1024x768x4)
After: 8,294,400 bytes (1920x1080x4)

Your video card and possibly the CPU has more than double the video to manage now so it could feel slower.

More RAM will not increase the speed of the CPU or the GPU.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
