If the machine is open use the following standard:  \n\n1). Always check connections first (remove and reinsert) - keyb, mouse, usb, video cable (all outside).  CPU chip, memory chip, video card (and others if present), power to motherboard, fans, reset or power button stuck, data and power cables to devices.  \n\n2).Follow (within limits) process of elimination:  If success add next most basic thing and continue until failure.  Move cards and memory to different slots as a quick test.  Remove everything but CPU chip and power to M/B.  Beep test - power up and listen for series of beeps;  no beep=check CPU, M/B or existence of  beeper/speaker.   Add memory, beep test.  Add video, look for output.  \n\nAt this point, test the hard disk LAST so it wont boot windows or be hammered for every test.\n\nAdd a power cable to floppy and test.  Add a data cable to same device and test, then try to boot a floppy.  Add power to next device, test, then add data to the device and test - etc.  Then add each card until failure.  Any failed item should be thoroughly checked out unless you're rich and will replace it then and there.  Sometimes certain M/B will not power up or boot without CPU and memory chip combo.  Some are intelligent enough to allow only CPU.  \n\nIf you are uncomfortable with any of this, take your box to a PC guru friend or a service and have them do a flavor of the above.  Don't let them tell you the thing is hosed - make 'em show you something from the above or similar tests.

Trying to solve a mystery? Wondering what others in the household may have been up to on the computer?\nThere are programs that track what people are looking at on their computers and you can see what others in the family have been doing on the computer.\nGo to www.cnet.com and look at downloads. There may be one there. Used very commonly in companies where employees work on computers, to see if they are goofing off.

Sounds like you want to do a little private eye work... hmm... try a keystroke logging program.  Some of the better ones even take screen shots that you can review later.  These programs are designed to work in the background where no one (except you) know they are tracking all activity on the computer.
