Windows 7: 4 crashes

I have attached the DMP files for 4 separate crashes. This is from an HP Mini 311. I don't use it much, but almost every time I do I get a BSOD. I try to restart in normal mode, Windows is unable to restart, so I have to restore.

Two of the times I crashed I was trying to install an update to Java (the Java task bar icon popped up to tell me an update was available. During the update I got the first two BSOD's in this zip.

The 3rd time I was using a web application at work that uses Java. A warning popped up asking me if I wanted to allow Java to be used, I clicked yes, within 2-3 seconds I got a the 3rd BSOD.

For the 4th one, I was looking at some of the features in the Desktop Gadget Gallery.

I believe all 4 BSOD were the IRQL_NOT_LESS_OR_EQUAL error.

All of these crashes were caused by your i8042prt.sys.

i8042prt.sys is a driver for the ps/2 ports commonly found on pc's.
The ps/2 ports are controlled by a chip that was made by Intel, the Intel 8042. It is some kind of a bus, that uses one port to talk to the controller and another one to talk to the devices. The devices have separate interrupts so they can notify the system when they have something to say. When that interrupt is received though, communication happens through the same port for both devices.
This means that there has to be a driver that coordinates access to these devices, or there will be problems when for example you move your mouse while you press a key that turns on one of the keyboard leds.
The Windows i8042prt driver is pretty much documented on MSDN. Most of the documented stuff should work in the ReactOS driver too, so hopefully third-party drivers, like for touchpads and other weird mice, can be made to work.

I would either update the driver or try to find alternative by third parties
