What this value means
This indicates that the GPU wrote to a range of Accelerated Graphics Port (AGP) memory that had not previously been committed.
AGP_INVALID_ACCESS identifies a stop-code family. The four bug-check parameters and dump, if available, help distinguish the actual failure path.
| Code | 0x00000104 |
|---|---|
| Short hex form | 0x104 |
| Symbol | AGP_INVALID_ACCESS |
| Windows family | Blue screen and stop codes |
| Source level | Microsoft bug-check page |
Microsoft’s technical cause notes add: Typically, this bug check is caused by an unsigned or improperly tested video driver. It can also be caused by an old BIOS.
The linked debugger page also describes its parameters: Typically, this bug check is caused by an unsigned or improperly tested video driver. It can also be caused by an old BIOS.
Safe next steps
- For 0x00000104 (AGP_INVALID_ACCESS), record the exact stop code and parameters. Microsoft’s debugger reference may describe a kernel condition rather than a consumer fix.
- If crashes repeat, inspect the dump locally with official WinDbg and compare its parameters with this code’s Microsoft page.
- Do not enable Driver Verifier or change firmware as a generic first step; ask qualified support if the PC cannot start.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
