    Thank you Th3_uN1Qu3. The video card was a ATI Radeon 128 MB AGP with heat sink and fan. I tested a subsititution with a a nVIDIA AGP video card and all was well. So removed the ATI drivers and installed a new nVIDIA e-GeForce 6200 256MB AGP and it appears to be working well. Its a 5 year old Dell that did not warrant a high cost solution. Thanks again!

The burning smell could be coming from the video card. Stripes on the screen indicate faulty video memory, shouldn't have anything to do with the power supply.

Have you checked in the rear of the system box to see if there is any perceptible air movement? The power supply is one of the junkiest parts of any system and the fan is the worst part of the power supply. If the fan blades are impeded by dust bunnies or the bearing has failed (very common), the power supply will fairly quickly overheat and will shut down.

I was burning a movie and my computer flash off than on than shut off.. it spelled like electrical wire burning. now it will not even turn on


Sounds like the power supply died. This is where your power cord plugs into the pc. It is a metal box inside the pc. Smell the back of the pc, at the fan opening closest to the power cord. If it smells burnt there, then you need a new power supply.

Hope this helps!

Burred smile coming inside the CPU

I believe you are asking about a burned smell coming from your PC case.
Firstly check your power supply as this is where the high voltage power is and therefor the most likely source of the burn smell.

You need a power supply! Go to Amazon and search for one that is the same specs as yours. Fairly easy to replace, don't use your old one anymore, it could be dangerous.

My Dell Inpiron 6400 has just died.

Most probably a power unit, mother board or a processor failure. Any of the three can happen. I recommend you to take it to a tech. If there is a Dell service station take it there. If it just shut down while you were working: Have you checked the battery. Have you tried it using the direct power? Any burning marks or smell? Have you checked the Adapter also? Check them. IF you use direct power were you using a surge protector? Have you dropped it? Does the start button work well? Any abnormal thing related to the button? Have you spilt water on the machine? If all are fine then you have to take it to a tech.

My Acer Laptop screen fades or goes out when moved

Try reseating the video cable/connector. Also connect an external monitor to the external video port, power up the monitor first then boot up the laptop. The video image should automatically divert to the monitor, if you see a normal video image then the video card is OK and the problem most likely the LCD screen.

Dell 2300 projects verticle stripes accross the projector screen.

this is due to improper power supply or a loose connection inside. the symptoms are of power supply unit inside projector. check out the current and amperes inside the projector on board. sometime the current stable but the ampears are down.also check the switching transistors & filters inside.......

Shuts down after power up

It is a power supply problem common with these machines. The only solution I have found that works is to replace the power supply.
