1x PCIe x16 (for dedicated GPUs), 2x PCIe x1, 1x legacy PCI slot, and 1x mini-PCIe slot (often used for half-height Wi-Fi cards).
If you are working on repairing or analyzing this motherboard, tell me what it is exhibiting (e.g., no power, fans spin but no post, loop-cycling). I can help you locate the exact power rails or test points to check next on the HIG41UATX circuit. Share public link
: Four SATA II (3.0 Gb/s) connectors and integrated Intel Graphics Media Accelerator (GMA) X4500.
Integrated Intel GMA x4500 with one PCIe x16 slot for discrete GPU upgrades.
A typical configuration for a 3-pin jumper (like CLR_CMOS ) is:
: Located near the bottom right, containing pins for the power button, reset switch, and HDD/Power LEDs.
). If your board fails to POST (Power-On Self-Test) or turns on but displays no video, the schematic lets you trace the voltage pathway.
Often points toward an unpowered CPU Vcore rail, corrupted system BIOS code, or systemic hardware incompatibilities within the installed DDR3 memory sticks.
Ensure the CR2032 battery holds ~3V. A dead battery can cause boot loops on older LGA 775 boards. Scenario B: No Display (Black Screen)
Locate the 8-pin SPI flash chip near the ICH7 Southbridge. Check pin 8 for +3.3V_AUX . Use an oscilloscope or logic analyzer on pin 1 ( CS# Chip Select) and pin 2 ( DO Data Output) during startup. If there is no pulse activity right after CPURST# drops, the BIOS chip must be desoldered and reflashed using an external EEPROM programmer. Shorted MOSFETs on +12V Input
LGA 775, supporting Intel Core 2 Quad, Core 2 Duo, Pentium Dual-Core, and Celeron processors.
