blue screen error (im a noob)

It sounds like your browser may be being hijacked by something, I had another look through your program files, PLease uninstall Browse2save then follow this tutorial and run a virus scan with WDO:

Windows Defender Offline

To Scan a Computer with the Bootable CD/DVD or USB Flash Drive

1. Insert or connect the same 32-bit or 64-bit Windows Defender Offline bootable CD/DVD or USB flash drive to the same type of 32-bit or 64-bit Windows computer that you want to scan at boot.
NOTE: For example, you can only use a created 32-bit USB on a 32-bit computer at boot, and you can only use a created 64-bit USB on a 64-bit computer at boot.

2. In the BIOS or Boot Menu of the computer that you want to scan, be sure that you have it set to boot from the CD/DVD or USB flash drive created in the STEP ONE section above, and boot from it.
NOTE: Please consult your computer's or motherboard's manual for exact details on how to do this.

3. This is what you will see while it's booting from the CD/DVD or USB flash drive.

4. When Windows Defender Offline has booted, you will be able to update the definitions and select what type of scan you would like to run on the computer. A Full Scan is recommended, and could take several hours to complete.
NOTE: You will only be able to update the definitions at boot if you are using a bootable USB flash drive with a internet connection, and not with a bootable CD/DVD.

5. When finished, close Windows Defender Offline to restart the computer back into Windows.

That's it,

Terribly sorry that it has come to that

Well I do hope that if Dell cant sort it out they will at least replace it, as far as im conscerned if a PC is still under warranty then its on the manufacturer's head to fix its problems not yours.
