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.

It Could be because your laptop is infected with Virus . Due to Virus your Explorer.exe File was corrupted. If now computer is all right after restoring then I'll suggest you to use Good Antivirus Program and regular update it and Scan your Window Regularly.
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.
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.
The second battery would replace the cd/dvd drive in that slot. Obviously you would lose the ability to play cds/dvds..The drive is easy to remove -just push on the button to the right and then pull out the drive. Hope this helps..Michael
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
If you bought it new then back up any files and take it back to the shop. If it's a second hand unit then you need to immediately back up to disc or pen anything you want to save. You are being warned that there is an issue with your hard drive. If this fails then you will lose all your information and computer won't fire up until you fit a new hard drive and install an operating system (if you actually have one). Once you have safeguarded your files it might be worth checking if your laptop is running too hot, which can damage a hard drive, is the fan switching on. There are programs free to download that can test the temperature.
Actually there are various types of customized firewire connections for your computer.
Here is a link to view some products that might work with your computer.
Also, there are different sizes of PCI cards available. You have to shop around to find an apropriate size.
