It dont cause problems for most cases, but sometimes it just begin to crash your pc even in safe mode. I used ubuntu liveCD to rename the giveio.sys and then, it crashed booting to safe mode at file Mup.sys...
is a speedfan file. speedfan use it to calculate the rotation speed of the fans and the temperature of the chips and without it, speedfan can't have access to the componets of the computer. Keep in mind this file can give access to virus pass the antivirus check and windows security. better to keep it out.
Cause my Windows XP to bluescreen
I have SpeedFan, and I scanned with TDSSkiller with all parameters, was suspicious and unsigned, but it's legit and part of Speedfan.
As others have stated, giveio.sys is part of SpeedFan or other similar Hardware Monitoring programs. For some peculiar reason, this file caused WinXP boot problems after cloning from a faulty SSD disk to a WD VelociRaptor; booting from the SSD had been fine all along, but now booting from the Raptor was broken. Removing the file allowed Windows to boot without incident.
Just open a command prompt and type net stop giveio followed by return, this will stop the driver and you can delete it from \windows\system32\drivers folder
The GiveIO tool enables the software direct access to the I/O ports.

Part of Speedfan. With new windows updates, hangs up the computer at boot. Need to start in safe mode and uninstall speedfan entirely and reboot.

Best practices for resolving giveio issues

A clean and tidy computer is the key requirement for avoiding problems with giveio. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the giveio.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
