Re: Pc start-up failure
It could be overheating. Make sure all the components and fans inside the tower a clean of dust. Get a can of compressed air and blow all the dust out. You could also try removing and re-seating all your pc cards, memory sticks and cables.

Switch ON the PC, boot the PC in 'Safe Mode' by continuously tapping F8 button after you switch On.
Let windows boot in Safe Mode and log in to windows.
Go to 'Start'--->Programs--->Accessories--->System Tools--->System Restore
Here you will have to check "Restore computer to an earlier time' and click Next Now you will find one Month Calendar window with Dates below, go to the previous month by clicking the '<' sign in the upper left hand corner of the Month Calendar and select any date that you see in Bold.
The detail of that particular date should show "System Checkpoint" and time on the right hand side box. Select that date.
Try turning on the monitor before the Compaq system box, if Win is doing what it should, it will 'find' a 'new device' and reinstall the drivers for it.
It may not look right but you can change the resolution after it boots up.
Sorry it IS the monitor this is a common problem, unfortunately, this is evidenced by the fact it still didn't work when connected to another machine,regardless of lack or message. Do a warranty claim.
vswright is right, you have to make a restore disk when you are happy that that system is running properly (this called system back up and restore) go to the HP support website (HP now own Compaq) and enter the make and model of the pc and download the device drivers you need, if you experience any problems, get back to us
