Hello here is the home page:
I think you have some kind of a virus or malware on your system.
Install this program and make a full scan:
You maybe have to start the pc in failsafe mode by pressing F8 while you reboot.
Install also a better FREE antivirus program:
Please uninstall any other antivirus programs before you install microsoft security essentials. Run a full scan when installed and updated.It`not great to have more than one anti virus program installed. Most antivirus programs have a background scanner running to protect you from virus vhile you surf on the internet open a file etc.With more than one antivirus program the pc`s performance will be decreased.
There are a lot of things that can cause a computer to shut down.This could also be the power supply.Try also to renew the thermal grease between the cpu and the fan but BE CAREFULL not to damage the cpu.
If you are unsuccessfull at resolving the problem visit a computer repair shop.
When you talk about checking memory, it's the physical RAM stick inside the computer. RAM does not have sectors like a hard disk drive. If it does happen to be bad I'd replace it with at least 1GB to 2GB. 512MB is really low.

Sounds like a bad motherboard, I try resetting the bios , removing everything but the video , could be a bad power supply too (if you have one jump the wires in there as a test). you can buy those dell MBs cheap on fleabay.

Hi, Thanks for using fixya.
I have the same computer with the same problem. I changed the power supply that cured it for me, I hope it does the same for you.
