Over the last year or so I have been getting the following message every now and again on my pc

"The NVIDIA System Sentinel is reporting that the NVIDIA powered graphics card is not receiving sufficient power.

To protect your hardware from potential damage or causing a potential system lockup, the graphics processor has lowered its performance to a level that allows continued safe operations"

I click on OK and can then carry on as usual until it pops up again.

Over the last few weeks the message is popping up more and more frequently. Today my daugher tried to play on The Sims2 but couldn't as every few seconds the screen was minimising and this message was being displayed. She has previously played this game for hours without any problems.

My PC is about 6 years old, was bought from Mesh Computers

AMD Athlon 64 Processor
3000+
2.00 GHz 1.00 GB RAM
NVIDIA GeForce FX5900XT

I have had problems several times with the power supply fan (a Mesh engineer came out to replace it when it was about 2 years old).

A couple of times over the last month I have also had an error message about the CPU overheating.

I do not really have any knowledge about the "insides" of my pc and I have no instruction manual for the graphics card to help me.

Help :thumbsup:

It sounds like your powersupply may be deteriorating and needs to be replaced.

Odds are that your system can use a regular ATX powersupply.

If your system is out of warranty, I'd suggest something from 400 to 500W as that should be more than enough for that videocard. One thing about powersupplies is that you get what you pay for. I'd suggest looking at something from Enermax, Antec, Cooler Master, Corsair, PC Power & Cooling, Silverstone, Thermaltake or Zalman. There are other good brands, but picking one of these should get you a good quality powersupply.

The CPU overheating could be due to the failing powersupply not moving enough warm air out of the case anymore, but it could also be that the fan on your processor's heatsink is starting to fail. This could be due to dust and could then be fixed with some compressed air and blowing out the case. If you've kept your computer case pretty clean it could also mean the fan on the heatsink is starting to slow down and may need replacing. Some of these fans are rather unique and you may need to replace the whole heatsink/fan combination.

6 years old, I'd say it's time for a good cleaning of the interior
We have a tutorial that is easy to follow:

As far as the power supply itself goes, I'm sure the tech put in an off-the-shelf, generic replacement w/minimum wattage
An upgrade to a more powerful one would probably be benificial
