My aunts laptop had all the symtoms of a infection windows were opening and closing by themselves the keyboard was typing out incorrect letters when pressed and the trackpad was making sounds as if it has been pressed when it had not but the laptop wuold always boot without fail.
So as there was no way to download cleaning software to clean the infection due to the keyboard issue I decided to plug the hard drive into a dock connected to my Mac and get her data off and wipe it clean which I did.
After re installing the hard drive into the laptop I inserted my aunts windows vista home premium disc and started up the laptop went into bios and changed the boot order so the DVD drive would boot first and when the computer booted passed the dell logo there was a flashing - in the top left of the screen and then the computer started beeping I tried a few more times but the same thing happened even switching back to the default boot order and using f12 to enter the boot menu to choose DVD drive but just the flashing - and the beeping (which keeps changing pattern) even trying to boot from a external optical drive was unsuccessful so I ran the diagnostics and it said "could not identify diagnostic partition" or something so I downloaded the diagnostic utility and burned it to a dvd but again it would not boot into the DVD.
So I am at a loss as to what is going on as the hard drive is the same one and the optical drive has not been touched.
Any help would be greatly appreciated.
Also the Num lock light is on during boot process and the top light on the right hand side of the laptop turns on and the second light flickers briefly but then goes off again.
Welcome to the Community,
I suggest you can try reseating the HDD and also try to remove the RAM and reseat it one at a time.First try removing and reseating the DIMM B (as it is easier to access) as shown in the link below,if that does not help than try DIMM A.
Use the link below for help to remove and reseat Memory Module:
The light on the Right hand top is the power light and the one below it ideally turns on when the computer reads or writes data.
Let me know if reseating RAM helps,

I first reseated the hard drive (which I forgot to mention was showing up in the bios before the reseating so it appears it was being detected) tried rebooting and got long sequence of beeps in quick succession which totaled more than 4 next removed and reseated RAM module B and restarted and still no boot but this time silence so moved on to RAM module A and reseted it and tried to reboot once again and still unable to boot and once again no beeps and on all occasions the Num Lock and power were on during boot.
So it could be an issue with one of the RAM module or the socket (DIMM A or DIMM B).So can you try booting system with one memory module at a time.Remove both memory module and try using both memory module,one at a time on DIMM B.Check if the system boots within any one of the memory module connected to DIMM B.
If the system does not boot,try DIMM A with one module at a time.This will help to isolate if its the memory module or the memory socket which is gone bad.
I finally got the windows DVD to boot without having to remove the ram a second time but now it appears that the symtoms have not cleared up the computer still thinks keys are being pressed when they are not for example when it came to typing in the product key the computer started typing random stuff in the product key box before I could do anything.
I have checked all the keys and none are stuck so something weird seems to be happening with the keyboard and the trackpad as the computer also thinks it is being pressed to select something when it is not.
So now not really sure what could be causing this as the hard drive is completely blank.
Try to release flea power and see if that helps.Disconnect the charger,remove battery, press and hold down the power button for 30 seconds.Reconnect the battery and plug in the charger and than try booting from Windows DVD.
As you are conforming there is no stuck key,try blowing some compressed air on the keyboard to make sure nothing is stuck between the keys.
I did as you suggested and initially I thought it had worked but about halfway through installing windows the laptop started doing things at random again and another problem I have now is seeing as I uninstalled windows that means all the drivers have had to be re downloaded I know how to find the drivers for the laptop but am not sure which of the downloads are the ones I need to get the laptop to connect to the internet as some of the downloads I recognise as being bloatware programs and no essential to reinstall so I don't want to install anything that is not essential as the laptop has very limited space..
Once you're on www.support.dell.com,Click Drivers and Downloads,Enter system Service tag number,Select your Operating System.To be able to connect to the Internet,go to Network in that list of drivers,download and install the Dell wireless or Intel wireless card driver depending on which card your system came with.Than also install the Broadcom-Driver for LAN (Local area network).
If you've reinstalled the Windows you need to reinstall the drivers in the correct order as given in the link below:
finally got the drivers installed but had to fight the laptop throughout as it was opening and closing windows at random and when I try to type something in the address bar in IE it is the wrong characters as it was before so disconnecting the power and battery for 30 seconds and blowing compressed air over the keyboard seems to have had no effect.
Connect a external keyboard (USB) to the system.Check if it lets you type normally with the external keyboard.If the external keyboard works fine, than it could be an hardware issue with the system keyboard, as you've already reinstalled the Windows.
I assume you've done a clean reinstall of windows i.e you have formatted and deleted the old partitions.
I just plugged in a external keyboard and it worked fine and yes I erased the original 2 partitions and created 1 partition on the internal hard drive and reinstalled windows to the single partition.
So if the external keyboard works fine,its an issue with system keyboard.If it was due to software issue, Windows reinstall should have fixed the problem.So after all the trouble shooting it looks like you need to replace the system keyboard.You can Call 1-877-717-3355 (US customers) to order replacement keyboard.
I am in the UK so What would the UK Number be for that?
Disconnect the keyboard from the motherboard and use an External USB keyboard.
If it still does this then liquid may have been spilled inside.
