To fix various driver issues on your PC, you will need a dedicated tool to find the freshest and the original drivers. You can use PC HelpSoft Driver Updater to do it in 3 easy steps:
TheOS_DATA_TAMPERINGBSoD, with error code0x00000155, appears when Windows detects an attempt to tamper or modify critical system files. Subsequently, the PC automatically shuts down to prevent data integrity.
The underlying causes forOS Data Tamperinginclude outdated drivers, malware infection, corrupted system files, applications that compromise the security of Windows, and hardware malfunction.
Before you proceed, restart the computer, install any pending Windows updates, and disconnect all non-critical peripherals and hardware. For most of you, these basic fixes should do the trick!
How can I fix the OS_DATA_TAMPERING blue screen error?
1. Update all the drivers
Outdated or corrupt drivers may give Windows the impression of data tampering, triggering theOS_DATA_TAMPERINGblue screen. In this case,updating the driversshould quickly fix things!
If Windows can’t find a better version, I recommend going to the manufacturer’s official website, looking for the new releases, and thenmanually installing the latest driver.
2. Scan the PC for malware
If the built-in Windows Security can’t detect any malware behind theOS_DATA_TAMPERINGcrash, you may consider using anadvanced antivirus solutionto run a series of scans and eliminate the active threats.
3. Uninstall recently added programs
4. Repair corrupted system files
Ifcorrupted system filesare triggering theOS_DATA_TAMPERINGBSoD, running theDISM(Deployment Image Servicing and Management)and SFC(System File Checker)scans will replace all such files with their cached copies, fixing the error.
5. Perform a clean boot
Aclean bootloads Windows with only the required programs, services, and drivers. If, upon reboot, theOS_DATA_TAMPERINGerror is fixed, re-enable the services and programs disabled earlier individually. When the BSoD reappears, the component enabled last is problematic and must be removed.
6. Inspect the Disk and RAM for issues
TheCheck Disk(CHKDSK)utility allows you to repair minor issues with the hard drive, including bad sectors, which may be responsible for theOS_DATA_TAMPERINGblue screen.
IfWindows Memory Diagnosticcan’t find any problems, I recommend usingMemtest86+, an advanced open-source RAM testing tool that will run a series of scans on individual RAM modules and detect even the smallest of issues. In case any problems are found, replace the malfunctioning module!
7. Reinstall Windows
When nothing else works againstOS_DATA_TAMPERING, the last option is toreinstall Windows. Since this may lead to data loss, you should move any critical files to external storage beforehand.
To reinstall Windows, connect a formatted USB flash drive to another working PC > go toMicrosoft’s official website> download theMedia Creation Tool> use it to create a bootable Windows USB > plug in the flash drive to the affected PC >change the boot orderto the flash drive > load Windows setup and proceed with the reinstallation.
One of these solutions must have helped you fix theOS_DATA_TAMPERINGblue screen. Before you leave, discover thecauses of BSoD, and take suitable measures to prevent them from reappearing!
