Moving from 32-bit to 64-bit Windows also entails upgrading to 64-bit versions of your applications--and most programs won't work any better afterward. The main reasons to upgrade from 32-bit to 64-bit Windows are to take advantage of a 64-bit processor (which most modern PCs have) and to use more than 4GB of RAM. If you don't have that much RAM, upgrading to 64-bit Windows may not be worth the hassle.

Why won't my motherboard beep as my PC boots up?
Most motherboards emit a loud beep when you power on the PC to let you know that they're working properly. If something goes wrong, they'll emit a specific sequence of beeps that you can look up in your motherboard's manual to troubleshoot the problem.
If your motherboard doesn't emit any beeps, and your PC isn't booting properly, the board may be dead. Verify that it is plugged in properly and try booting up again; if you still don't hear any beeps and your PC doesn't power on, you may need a new motherboard.
Alternatively, the motherboard may use on-screen notifications during the boot sequence, and LEDs on the motherboard itself, in place of beeps.
What is IPS, and why is it desirable?
When shopping for a new monitor, you may be puzzled about the difference between displays that employ Twisted Nematic panels and displays that contain newer In-Plane Switching panels.
IPS panels are superior to older TN panels because they can display images with a broader range of color and brightness values, and because they offer a wider range of good viewing angles than TN displays do. In addition, IPS panels don't react as strongly to touch as TN displays (which tend to lighten and blur under pressure), making them ideal for use as touchscreens. Though IPS was initially developed in 1996, the technology is still not standard; thus, when you compare monitor models, you may see displays that offer TN panels and such IPS-panel variants as Super IPS and IPS Pro.
Most IPS variants offer improvements over the basic IPS-panel technology. Nevertheless, a few good reasons remain for preferring an older TN-panel display to an IPS-panel display. Because TN panels are cheaper to produce, monitors that incorporate them tend to cost less. Also, TN panels can achieve greater brightness levels than most IPS variants, and they have much faster refresh rates, which makes them better for stereoscopic 3D applications.
