All comments about giveio.sys:
you better delete this rob
It seems an Intel driver (I'm no expert) according to what I found on Google Gerrit Plasman
device driver for NT 4.0/2000/XP The giveIO tool enables low-level access to I/O ports for programs under Windows 2000 and XP. This is needed for some software that communicates through LPT ports. (Some people say that UserPort is better for Windows XP
Input/Output for gamepads  See also: Link Darek Ali
2000/xp dll to directly acces serial /lpt ports pete
No idea what it is, but it hangs the windows boot process, even in safe mode, and even after deleting it. So far the only solution is a reformat. Jonathan Wright
it is for running a system monitor program  See also: Link Krystal Rose
used for system monitors, like temperature probes for cpus fu3lman
Installed as part of SpeedFan Freeware (and probably other software)  See also: Link Seajay
This file is for allowing programs low-level access to parallel and serial ports. Andy
It is a widely-used driver to allow user-mode programs to access hardware registers and I/O ports, such as for controlling fan speed or monitoring temperatures. It is generally safe, although since it uses undocumented kernel calls it may cause instability on future versions of Windows. If that's the case, or you don't use any programs which need direct hardware access, you may freely remove this driver (from the Non-Plug-and-Play Devices branch of Device Manager--don't just delete the file). Otherwise it poses no threat.  See also: Link BST
It is a pesky rat installed by SpeedFan. Foolw the link to get rid of it ("disable") rather than "automatic"  See also: Link Stephen
used by temp control programs like speedfan and mbm5 mike
it makes paralle port accesable in windows jim the tech

Used by SpeedFan
On my computer it was installed by a freeware program called Speed Fan. Monitors Motherboard, Processor and Fans for voltages, temperatures and fanspeed  See also: Link Osscar Grouch
in my case most likely installed with application SensorsView beta 1.0, fan speed and temperature monitoring software; translate link with google, info under 1/26/06  See also: Link aaron
I'm sure its used by SpeedFan
Essential component of speedfan! DavidR
Used for direct access to the LPT Parallel Port for example for Holger's Parallel Port AVR Mega Prommer sylwek
windows XP and certain other OSs restrict access to the serial, parallel, and other ports. Many programs therefore have to use this sys file to access those ports, rather than having their own device drivers, with dlls, to access external hardware. Alex Wojtak
Allows access to Printer Port For comunication! Pudge
Installs with speedfan utility to monitor temperatures, adjust speed of conected fans, etc. zimbabwa
Installed by speedfan, used by other hardware monitoring programs Chris www.getcarspares.com
Harmless, NOT cause of any crashing or such - Used for reading temp-propes etc. (by SpeedFan among other such softwares)  See also: Link Anon
This is driver that gives access to low level registers. It could be used by any program. It's not provided by Windows
We use it at our radio station to start a logging program with a contact closure via the parallel port.  See also: Link Radio Connie
Speed Fan (V 4.32) seems to run pretty well without it; Windows XP doesn't like it, says it is "destructive" ;- Charles D. Bohne
I had the Speedfan problem too. It was working fine for months, until an automatic Windows XP update caused it to conflict. The solution was to uninstall Speedfan entirely, through Add/remove Programs. Rebooting afterwards worked fine. Chris P.
I had this problem, and after much looking around for answers, discovered XP desided it didn't like one of the USB devices I had hooked up. I ran into the problem after upgradeing Quicktime to the latest version. Richard Ballard
It is for direct access to paralell port.It is OK Alda
Mine was added by a Quicktime update and totaly crashed my system. Removal looks easy enough, but as the system locks even in safe mode, can be a real pain to correct sometimes. Richard Ballard
It is possibly correct that it is installed by SpeedFan. I installed this recently and noticed this today after my computer froze and then refused to boot, even in safe mode. I repeatedly saw that giveio.sys was the last driver attempting to load in safe mode before crashing. So I booted into Windows 98 (have both for emergencies) & renamed it and then was able to boot in safe mode and restore ( just to be safe ). But I have been using SpeedFan for a week now, dunno why it suddenly caused problems. The latest thing that I installed was FeedReader though how they're related I really can't see.  See also: Link nogoodatcoding
installed with speedfan, not used by any other program JohnS
Speedfan, PC hung even in safe mode.
In my XP SP2 before Speedfan I don't remember seeing such driver... now it's there. Gibe
Allows win98 style acess to LPT ports. Great if you want to use the LPT port as a GPIO device (inp and outp instructions). There is a small security risc but as long as you know what you are doing it no problem. Tom
this File is a firmware driver for for amv based hardware clcurry1
Causes my system to hang on boot and cycle boot infinitely; unhappy running with XP SP3 RC1 lenny
This is installed by speedfan and has crashed my pc, on reboot, can not get past givio.sys WARNING Pete
Allows direct port i/o on windows nt/xp/vista. Not dangerous by itself, poorly written programs that use direct i/o can cause system instability.  See also: Link happycamper
This file giveIO.sys is used and installed by Speedfan and other programs. It worked for me for a year, but eventually caused my system to hang on it, including save mode, last known good config etc. Even my Windows XP boot-CD hung and would not let me into the recovery console. This file seems to cause problems with certain Windows and iTunes updates as well as USB devices. I was able to recover by unplugging any and all USB devices (including internal), booting and uninstalling Speedfan. The file itself poses no security risk, but a severe incompatibility, that's why I rated it 5. JML
installs with Speedfan, no problems with other computers, notice on this new computer it prompts me that I am removing giveio.sys when I uninstall. syphonxtc
safe mode crashes when it reaches this file; I removed it an can start up Windows now Vincent
It allows some programs to access hardware directly in XP. Like embeded systems programers, or CPU temperature monitors.  See also: Link Shaunak
bluescreen your computer and make u not able to load the windows and its auto restart your comp Lim Ke Wei
my PC hangs in safemode after booting giveio.sys ( I just recently updated windwos which i think caused the problem) I wouldnt trust this file, get rid of it. Joe
installed by speed fan (though others may have the same name, the dangerous one is installed by speedfan) it actually doesnt cause any problems at all untill windows decides to update your pc.....creating conflicts and now cant boot eather in normal or safe mode. i have been using speedfan for more than a year, looks like it is time to say good by to it :P:P:P hewhoisnameless
My parents' computer keeps resetting during boot, even in safe mode. They definitely have speed fan installed.... I put it on for them months ago. Why it's acting up now is beyond me. Possibly a windows update. They are running XP SP2. John T
SpeedFan (nice sofware) need giveio.sys  See also: Link Pi
system hangs after giveio.sys. Even in safe mode. Windows XP 32bit SP3. ankorot

used by speedfan Michael K
This is a driver file installed by Speedfan. A program used to control the speed of fans on your computer to keep it cooler. Im sure this can be removed thru uninstalling speedfan, and appears to be no threat to a computer. Savonna
It IS part of the Speedfan installation. This file is NOT signed by Microsoft (use sigverif tool). If you're having problems it might be worth uninstalling the program. Rob (1st poster) is an ignorant fool. JR
hangs PC cant boot up. worked ok for 4 days. how to delete vjain1234 at yahoo dot com
giveio.sys appears to be related to the program speedfan. what you can do (only way its working for me thus far) is place HD in another pc as a slave drive then access the hard drive from your normal operating system and delete this file (it is not owned by microsoft as you can see if looking at other *.sys files) the location of this file will be under WINDOWS SYSTEM32 GIVEIO.SYS just delete the file. it seems to be that the file causes a conflict upon start up after a certain update from MS (yet to be determined). i have to put HD back in original pc and see if it works. will repost after..

Definitely part of SpeedFan distribution (pub by Almico) and installed in \System32 (5248 bytes dtd 04-03-96 12:33:26)  See also: Link Art K
I have been using speed fan for over a year and haven't had any problems with it until today. My computer would not load windows or safe mode. So I unplugged all USB devices and then was able to get into safe mode. I deleted giveio.sys and restarted without any problems and then uninstalled speed fan. But now none of my UBS devices are working. Jason
Installed with speed fan and other utilities of the like. Certain windows updates may/will cause your machine to hang after the update is installed. giveio.sys is harmelss itself. If you do install speedfan, make sure you have all your updates done first. NOD32 doesn't say it's a virus. A quick look at it with IDA doesn't raise any red-flags either. Jennifur Pawsom
It Hangs The System, Even AFTER Deletion Andey
C:\UBCD4Win\BartPE.iso\I386\SYSTEM32 It is either in C:\Windows\System 32 or C:\UBCD4Win\plugin\System-Info\Information\SpeedFan\files J Carlin
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. Teliger
The GiveIO tool enables the software direct access to the I/O ports.  See also: Link Pavel Rybka
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 Daniel
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. stylez
I have SpeedFan, and I scanned with TDSSkiller with all parameters, was suspicious and unsigned, but it's legit and part of Speedfan. TJ
Cause my Windows XP to bluescreen Justin
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.
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... Kaspar
caused my xp to hangs even on safe mode... delete, delete, delete!! Roey
i detected it with sigverif.exe win 7, when i uninstalled Speedfan it gave warning whether to keep it or not, after uninstall i ran sigverif again and it was gone, i decided its unsafe since lots of people reporting blue screens and hangs but it is part of speedfan erik
Was installed on Win7 machine by Speedfan program. Asked if I wanted to remove GIVEIO Servide during uninstall of Speedfan. Said yes. It's gone, and everything works fine now.
