Boot Issue due to Using D drive full capacity

Question

I have a Rack mounted personal computer with windows 10, I was running a software which store data in D drive, during data recording my D drive get full and system showed notification that "connection lost with data folder", then I free some space in D drive but software doesn't work. I tried restarting the pc, the PC started once but software doesn't operate then Tried restarting again but the PC doesn't start. On clicking power button just fan start and then turn off in 3 to 4 second. I want to know that D drive can cause this issue or not. If yes, then how?

Answer 1

Filling the D: drive to 100% can cause application failures and sometimes Windows instability, but it cannot by itself cause the symptom where pressing the power button makes the fans spin for a few seconds and then the PC powers off before Windows even starts. That behavior indicates a hardware or firmware/power issue, not a data‑disk space issue.

How D: being full can cause problems:

• Applications that write data to D: can crash or lose connection to their data folder when there is no free space.
• If D: hosts paging files, temp folders, or application databases, running out of space can cause errors, hangs, or even a blue screen while Windows is running.
• In some cases, if the system drive (usually C:) is also very low on space, Windows can become unstable or fail to boot with errors such as INACCESSIBLE_BOOT_DEVICE or other stop codes. In that case, freeing space and running tools like Check Disk or System File Checker can help, as described in the references.

However, in the described scenario the system now fails before Windows loads (fans spin briefly, then power off). That is earlier than any Windows disk or file‑system issue. Likely causes include:

• Power supply problems
• Motherboard, CPU, or RAM faults
• Short circuits or loose connections
• Overheating or hardware protection triggering an immediate shutdown

So:

• D: being full explains why the software stopped working and lost connection to its data folder.
• D: being full does not explain the current power‑on/power‑off behavior; that points to hardware or BIOS/UEFI‑level issues, not to the D: volume contents.

If Windows could still boot but showed a blue screen such as INACCESSIBLE_BOOT_DEVICE (0x7B), then storage configuration, drivers, or disk failure would be relevant, and the troubleshooting steps in the references (Safe Mode, disk checks, SFC, Event Viewer, hardware diagnostics) would apply.
