Before install the new ram, it is recommended that you wipe off the gold contacts of the new ram with some alcohol. You can also use pencil eraser to wipe off the contact. Did the new modules fit and lock down?
Link below to Dell - then download Service Manual. There, you'll find the procedure for removing and installing new memory module.

You can remove or change the Window's User or administrator's password. You need access to a computer with Internet access to download the Hiren's Boot CD and burn it onto a CD. Then insert this CD into the laptop/computer and boot up the laptop/computer with the Hiren's CD and follow the instructions. There are very useful utilities CD and it a Linux boot CD which contains quite a lot of Utility programs including a password removal program.

This is an error message your operating system boot manager file is corrupted or missing. A clean re-install may solve the issue. Sometimes you need to format the entire HDD to install the OS. Remove the HDD from the drive bay and connect it to another pc using an external 2.5" case via usb cable and select that HDD from computer and rightclick then format. Select ntfs if needed. Untick the quick format and click OK. it takes a while to finish. After format complete remove the HDD and refit it in your laptop and re-install OS as usual. Hope this helps.

Are you able to get to the desktop in safe mode?
Repeatedly press F8 on startup and choose to boot to safe mode in the options window.

If you have a Windows 7 disk, then you can boot from that and do a "startup repair". It is able to repair a lot of issues with no trouble.

Upgrading your laptop OS from Vista to Win 7, you have to reinstall your Bluetooth drivers for Win 7 OS(ie x86bit or x64bit) for the Bluetooth to function properly.

Dell Inspiron 1545 download @ http://support.dell.com/support/downloads/driverslist.aspx?c=us&l=en&s=gen&ServiceTag=&SystemID=INSPIRON1545&os=WLH&osl=en&catid=&impid=

Under "Network" -> Select your correct Bluetooth drivers versions for your OS Win 7 (i.e. x86bit or x64bit) to install.

Hope it helps.

yes is a problem with your SO.
the simplest solution is to reinstall OS

Reboot and enter your bios (instructions are on the boot screen), reset your bios to defaults. If you're using a synaptics touchpad, they're a bit finicky and you need to remove your existing software in the control panel and install a fresh copy of it.

Sir,
it is no driver problem but of your Windows ... sometime while updating Windows it get shutdown improperly or say for any reason its update installation stop and therefore this problem occurs so you can reinstall your windows and it would be fine.

Did you do an upgrade or new install? Did you check the system requirements first to see if you could upgrade to Vista? This could all play a part in why it does not boot up. I suggest you reinstall windows XP again.
