  Computer shuts down, PSU at fault? 
 Date Written

Hi guys.

I recently purchased a rig from Dell, and I did that planning to insert my old GPU into it and save some bucks. This has and is working pretty well atm, although I had to also put my old PSU into it cus the one I got with the computer lacked the 6pin GPU-powerslot.

Anyway, most of the time the rig is working perfectly fine. But at about 3 occassions there's been the annoying event that my computer just shuts down. No kind of bluescreen or error msgs, it just dies. Every time has been during a point when I was playing a game. Starting it up works perfectly again afterwards (thank god).

I have 2 things I personally am suspecting could be the problem.

1: My PSU is at ocassions incapable of supplying enough power, most likely due to my GPU which is an ATI Radeon HD 4850 and a powerhungry beast and its cooling fan spins up like nuts when I play a game.

2: The rig gets too hot, like I said I have the ATI Radeon HD4850 and it's currently using the stock cooling, which is poor indeed and it does indeed run pretty hot when gaming.

So basically I was wondering about your opinions, does either of these 2 suggestions sound like they could be the cause of the computer just dying all of a sudden? Which of these 2 would most likely be the reason for my problems? I'm leaning towards number 1, but don't want to buy a new PSU if the one I have might be quite sufficient.

Read the PSU requirements for that video card or GPU, and your other Hardware such as the CPU. The graphics card usually states certain Amps and Watts.

Computer's usually shutdown due to overheating of the processor or some other component. But, I have seen this happen with a faulty motherboard which has a blown capacitor on it.

As Joshua said, check the requirements, but... When you post a comment such as this, also post what psu you have and how many watts etc.

We need to know what cpu you have as the newer ones take more power.

Two things to try.
1. take the side off of your pc case and have a fan blowing on your card. Often if a card is over heating, you will see artifacting on your monitor or your pc may even freeze/lock up.

2.Get a 6 pin connector and try your Dell psu. (newegg link)
