Question
A user, Joe, has just finished upgrading his computer with a wireless keyboard/mouse combination, additional memory, installed new speakers, and replaced his 15 inch flat screen with a 24 inch flat screen. When he boots the computer it immediately starts making a loud beeping noise and will go no further in the boot process. Which of Joe's system upgrades is the cause of the problem?
Options
- AThe DVI cable is not properly seated
- BSpeakers are not properly connected
- CBattery low on wireless mouse
- DMemory is mismatched

Explanation
Loud beeping at startup that prevents the system from booting is a POST (Power-On Self-Test) beep code - the BIOS's way of signaling a critical hardware failure before video is initialized. Of all the upgrades Joe performed, mismatched memory (wrong type, incompatible speeds, or mixing DDR generations) is the classic cause of POST beep failures. A loose DVI cable would typically allow boot to continue (just with no display). Speakers not connected are irrelevant to POST. A low wireless mouse battery would not halt the boot process. Only a RAM incompatibility rises to the level of stopping POST entirely.
