Good catch by and thanks to 's followup — this is a classic small-BIOS-setting change rather than a faulty stick. A few quick, practical checks help avoid head-scratching if the displayed RAM changes again.

Open the firmware/BIOS first and note any entries named "Integrated/Onboard Video", "UMA Frame Buffer", or "IGD/Shared Memory" so the reserved GPU amount is visible. In Windows use System Information (run msinfo32) and Task Manager -> Performance -> Memory to compare "Installed" vs "Hardware reserved" values. For per‑module detail use a tool such as CPU‑Z or check the labels on the DIMMs. If the numbers still look wrong, reseat modules, test one stick at a time, and run Windows Memory Diagnostic or a bootable memtest to rule out faults.

Two quick causes to keep in mind: a cleared CMOS (dead CMOS battery or a firmware reset) can restore default video-memory reservations, and manufacturers/OSes use different MB/GiB math so small discrepancies are normal. If an integrated GPU is unwanted, installing a discrete card or lowering the shared buffer in BIOS will free more system RAM for Windows.

maybe you have onboard video sharing the ram ,and the amount of ram to use for video is set in the bios and maybe the bios got reset to defaults and the default amount setting was lower than a custom setting amount !!
Also maybe you have onboard shared video and you added a pci or agp video card ,tell us more !!
