Technical Troubleshooting Guides
Step-by-step walkthroughs and command-line fixes for common hardware, OS, and network issues.
1. Fixing No-Display & Failed POST Boots
If your PC lights up but fans spin with no video output after installing new hardware or tuning settings:
- Disconnect the AC power cord from the back of the PSU.
- Remove the graphics card or access the lower motherboard section to locate the CR2032 coin battery.
- Pop the battery out for 5 minutes (or bridge the `CLR_CMOS` jumper pins) to reset system BIOS to default factory specs.
- Re-seat memory modules firmly into motherboard DIMM slots until both clips click.
2. Resolving IP Drops & DNS Resolution Errors
When pages fail to load or local network discovery drops, execute a network socket reset using Command Prompt:
ipconfig /flushdns
netsh winsock reset
netsh int ip reset
Note: Run Command Prompt or Windows Terminal as Administrator before executing these commands, then restart your PC.
3. Initializing & Partitioning New SSDs/HDDs
If a newly connected drive does not display in File Explorer:
- Press Win + R, type
diskmgmt.msc, and hit Enter to open Disk Management. - If prompted, initialize the target drive using GPT (GUID Partition Table).
- Right-click the box labeled Unallocated Space and select New Simple Volume.
- Format the partition as NTFS (for Windows environments) or exFAT (for cross-platform access) and assign a drive letter.
4. Scanning & Repairing Corrupted OS Files
To repair system crashes or corrupted core Windows system binaries:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
