Sony VAIO PCV-RZ54G PC Desktop keyboard errors in event viewer


The I8042prt.sys is a system function driver found in Microsoft Windows 2000 and later versions for PS/2-style keyboard and mouse devices. If I8042PRT.sys is disabled or missing from the Registry this could be the cause. First check in Device Manager, a black exclamation point (!) on a yellow field appears next to these devices?

See if you can update the driver.

Lets check your registry. Here is the key: HKEY_Local_Machine\System\CurrentControlSet\Services\ i8042prt:Imagepath=System32\Drivers\i8042prt.sys
It should be there can you check to see if it's still there? Here's how:

Click Start > Run > Type: regedit

When Registry editor opens expand local machine> system >CurrentControlSet> Services> (Scroll down till you see i8042prt and click on it.

And tell me what the data entries for Start (should be 1)

Then expand the i8042prt key and select "Parameter" tell me in detail listed for the layer drivers; exactly what you see then select "Enum" Tell me if you see a file name "1" and data: ACPI\PNP0F13\4&1506bb2e&0

We might have to enable or add the port.

I'd suggest running a repair if you have your windows installation disk or do System Restore in Safe Mode, if unable to do it in Normal Mode.

Try tapping F8 at startup, and from the list of startup selections, select Safe Mode by using UP Arrow Key to go there > then hit Enter.

Try a System Restore once there, pick a Restore Point before your problem started (if there's a restore point that goes further back prior to your malware issue I'd suggest that restore point)

Here's how to access system restore:
Click Start > Programs > Accessories > System Tools > System Restore > pick a different time > Next > etc

If that doesn't fix it you might have some viruses and malware.

Start your PC and press F8 several times until the boot menu comes up. Then select "Safe Mode with Networking". Now get some or ALL of the FREE programs below.

Download, Install and Run Malwarebytes Anti-Malware:
http://majorgeeks.com/download.php?det=5756
When Installing choose the non-pro version.

Download, Unzip, Install and Run TDSSKiller:
http://majorgeeks.com/Kaspersky_TDSSKiller_d6895.html

Download, Install and Run Super Anti-Spyware:
http://majorgeeks.com/SUPERAntiSpyware_d5116.html

If you have an outdated Anti-virus program then Download, Install and Run Avira Anti-Virus:
http://majorgeeks.com/Avira_AntiVir_Personal_-_FREE_Antivirus_d955.html
Make sure to select ALL of the "threat categories" when you install or configure Avira...

If none of the above works you should seriously think about switching to a USB mouse and USB keyboard. The i8042prt.sys driver is ancient and it only controls PS/2 mice and keyboards (Doesn't affect anything else).

My USB Ports of Sony Vaio VGN FW235 stopped working


first remove all the USB Devices connected to the Computer, go to Device Manager, uninstall all the USB Drivers and restart the Computer. after the restart, the Operating System should reinstall the USB Drivers automatically as the USB Drivers are Operating System generic.
If this does not work, go to Device Manager, right click on the USB Device having Yellow Exclamatory mark and click on Update Device/Driver and select search for the best driver in these location and in the location type C:\Windows\inf and click next.
This should resolve the issue.
If this does not work, you can try performing the System restore where the USB ports are working normally.

My sony desktop will nolonger recognize my ipod or my camera when I plug them into the usb port. It will however recognize my blackberry and my Ipaq. Please help


I assume you are running windows operating system. You need to uninstall all your usb devices. Go to computer manager/device manager and select all USB devices and unistall them. Go to the start menu, click on run type compmgmt.msc. Find all your USB devices on the right side. Follow the instructions for each device to uninstall them by double clicking and then select uninstall. once you uninstall, click on the icon to scan for hardware changes located on the sub menu. Your operating system should recognize new hardware or reboot and the operating system should install them automatically ageain. Try this, I hope it helps.

Sony Vaio sound...


Adam,

The sony VAIO Pcv-j200 only runs with Windows 2000, windows Me and windows xp. The current operating system Vista on your computer right now will work but some of the features of it may not. The link below shows all the drivers for your unit for diffent operating systems (not vista). What you can try to do is to download the audio driver for windows xp
