| Symptom | Most likely fix | |----------------------------------|---------------------------------------------------------------------------------| | No power, fans don’t spin | Check 24-pin + 4-pin power connectors; test PSU with paperclip trick. | | Beep code: continuous long beeps | Memory not detected – reseat RAM, clean gold contacts, test one stick at a time.| | 1 long, 2 short beeps | Graphics error – reseat GPU or switch to integrated video (remove discrete card).| | PC powers off after 2 seconds | CPU overheating or bent socket pin – check heatsink mounting, inspect CPU pins. | | USB keyboard not working in BIOS | Use PS/2 keyboard or enable “Legacy USB Support” in BIOS. | | Boot loop after BIOS change | Clear CMOS via JBAT1 jumper. | | SATA drive not detected | Switch BIOS SATA mode from IDE to AHCI (or vice versa). Also check cable. |
