a noise may accure in power supply due to a short circuit or fan does not run properly. if you smell like burnt then you should remove the power supply from pc and open it. then check the capaciter and other element and if you find any broken capaciter then change it with it original value.

What graphics card is compatable for hp d530

I'm not going to go through a list for you, but I can tell that you don't have many options. The HP Compaq Business Desktop D530 uses a small form factor which means you don't have the same space as normal desktop users inside of your machine for the vast majority of display adapters. You would need at least a medium form factor for that.
The other problem is that your power supply is only 185W and can't supply the the amount of power needed for most desktop class display adapters.
The machine you are using wasn't designed to ever be used for gaming, and it shows. You would need to get a bigger computer case and higher watt (around 400 to 600 watt) power supply to support most desktop display adapters.

Will not power on

First, the simplest item is to make sure it is plugged in. (this includes making sure if you have it plugged into a power strip, that the power strip is powered on)
Second, some power supplies can actually have an On/Off switch in the back. If your PC has one of these, make sure it was not accidentally bumped off.
In very rare cases you could have an excess of dust in the fan and the power supply (you can try compressed air into the back vent to blow out dust in the power supply)
Once you verify those, another thing you can try, is to remove the front face plate (if there is one on the model you have) and try pressing the small button that is directly behind the power button.
The power button on the faceplate is typically just a piece of plastic that extends back and presses this button behind it. It makes it look pretty.
Beyond that, further troubleshooting requires opening the case to your computer. Typically, the power button has small wires that connect back to the motherboard or power supply, which could be re-seated (unplugging and re-attaching the cable on either end, to verify that it's connected properly) Also, the power supply has a connector that plugs into the motherboard, verify that this is connected properly and reseat it.
If all that fails, it is very likely you have a bad power supply. If the machine is under warranty, contact the manufacturer, and they may replace it for free. Otherwise you may need to order a new power supply from them (I believe Compaq uses proprietary power supplies and therefore you would most likely not be able to buy one from a retailer and replace)
If you are uncomfortable cracking the case on your computer, you may want to find a local techie to assist you.

The tower has a self contained power supply module that is the problem, it must be replaced for a new one, you need to bring the tower to a computer repair store for service, because they have to install the correct power supply for your model.

Does the above have a fuse inside the case / AC power supply? PC has suddenly developed a start up problem - power on light flashes once for a split second then power (appears to) cut off. Any idea(s) as...

yes you will find 2 or 3 fuses inside the power supply, see and smell for some burnt parts, like trancistors it will be 3 or 5 legged device with a metal back.
if some thing is burnt do not replace fuse the power supply needs to replaced.
beware replace fuse only if no parts are burnt, do not test in open state to avoid electrical shock.

Burnt Power Supply

You can try replacing the fuse in the power supply if it has one. Most have a permanent circuit breaker that once tripped, the power supply is no more. If you can change the fuse, there's a 90% chance it still won't work since there was a burnt oder, which indicates the fuse didn't blow fast enough to prevent more damage, like the motherboard.

I would like to upgrade my motherborad and i dont know witch one to buy


You may have issues with upgrading the motherboard on a Small Form Factor (SFF) desktop computer. The issue is not the space for the motherboard - it is with the proprietary power supply that HP/Compaq use with these small desktop computers.

You will be forced to use the existing power supply which may not work (i.e. have the correct power connectors) for the new motherboard.

Let us know what your goals are for the motherboard upgrade (have more RAM installed, add a SLI video card, faster processor, etc) and we can assist with what is and is not possible.

Pc sht down stating thermal error. suppose processr fan not working. can this be the cause of the eror?

Most of the time you'll never hear the CPU fan. If you don't hear the normal fan sounds coming from your computer, it is most likely the power supply cooling fan. Hold you hand at the back of the computer where the power chord plugs in, while the computer is running, and test if you feel air blowing on your hand. If you don't, then replace your power supply. Make sure, when checking for a new PS that you get the correct pin count. Best to order from Dell since proprietary systems usually use proprietary parts and a generic PS won't fit in the opening at the back of the computer (alignment of the plug and the fan with the opening, etc.)

Unplug it from power.Pull the side cover to check for burnt smell or burnt spots on your board modem or power supply. Unplug the power suppy from the board, unplug the hard drive . Then plug it all up again , put the cover back on it .Plug power cords back up and try it again.If you get no where after this the surge knocked out your power supply or hard drive or board. Always use a good surge protector on all computers and printer and copiers.
