Fix all BSoD events and keep computer safe and clean:
Fortect will find the cause of BSoD and fix it. Here is how to do it with 3 easy steps:
TheINVALID_REGION_OR_SEGMENTblue screen error, with code0x00000099, is encountered at boot and generally arises due to problems at the system level. According to Microsoft, the BSOD appears when theExInitializeRegionorExInterlockedExtendRegionfunctions are called with invalid parameters!
The primary causes ofInvalid Region Or SegmentBSOD include issues with the RAM modules, low or unstable power supply, problematic device drivers, corrupt system files, outdated BIOS, and hardware malfunction.
Before we start troubleshooting, install all pending Windows updates, disconnect the non-critical peripherals, remove any overclocking, andfix overheating issues.
How can I fix the INVALID_REGION_OR_SEGMENT blue screen error?
1. Install/update the drivers
When you areupdating the drivers, only devices that have a dedicated driver installed are listed. As for the ones that don’t have a driver, especially any recently connected devices, you must visit the manufacturer’s website, locate the new releases, and thenmanually install the latest driver.
2. Repair the corrupt system files
Corrupted system filescan affect the PC’s core functioning and are a commoncause behind BSODs. To get rid of them, you must run SFC(System File Checker)andDISM(Deployment Image Servicing and Management)scans to replace all protected system files with their cached copies stored on the PC.
3. Uninstall conflicting apps
Sometimes, programs leave behind files that can trigger BSODs even after uninstallation. In such cases, it’s best to use atop-rated software uninstallerto get rid of all leftover files and Registry entries.
4. Uninstall recent Windows updates
5. Check/repair RAM and disk
5.1 Repair the disk
The built-inCheck Diskutilitycan fix common hard drive errors, which often result in theINVALID_REGION_OR_SEGMENTBSOD. As for the complex errors, you will need anadvanced disk repair tool.
5.2 Inspect the RAM
If no problems are found, I recommend you useMemtest86+, an advanced open-source memory testing tool that will run a series of tests on individual RAM modules and identify even the smallest of the issues.
6. Update the BIOS
BSOD errors likeINVALID_REGION_OR_SEGMENTandAGP_INVALID_ACCESSappearing at boot often indicate issues with the BIOS. In this case,updating the BIOSis the best solution!
Since the process to update the BIOS slightly differs for each manufacturer, I recommend you check the OEM’s website for the exact steps and follow them. The update process is critical and any mistakes during it can render the PC unusable.
7. Reinstall Windows
As a last resort, you can alwaysreinstall Windowsto eliminate all software-based conflicts!
To do that > connect a flash drive to another PC > go toMicrosoft’s official website> download theMedia Creation Tool> use it tocreate a bootable Windows USB> plug into into the affected PC >change the boot orderto the USB > load the Windows setup > install Windows.
If you still encounter theINVALID_REGION_OR_SEGMENTblue screen after a reinstall, it’s a hardware issue to blame and you must visit a local repair shop to get the PC inspected!
Advanced users can, however,check the BSOD crash logs, identify the problematic component(s), and take the necessary steps for resolvingINVALID_REGION_OR_SEGMENT.
