    Do you see any diagnostic lights on your motherboard after plugging in the power supply?

    If so are they green?

Sound like 'classic' failing capacitor symptoms to me... RMA the power supply if you're able to, start scraping together some cash for either a rebuild (replace capacitors) if you can't OR purchase a NEW PSU

Once you get the system running... I would recommend you leave it turned on 24/7 as this will keep the failing capacitors at a static temperature (instead of the heating/cooling cycle) thus milking the last bit off life out of it while you secure a replacement unit.

Where can I find power supply for HP model ATX300-12ZBD

There are lots of ATX power supplies on the market. You do not need to use a HP 300 watt power supply. Just purchase one that suit your requirements - 300 watt or more. These power supplies have standard mounting holes.

Why did my coolermaster 550w stop working?

Because last tuesday was after the 25th day in the month meaning all electrical items fail intermittantly, and so the 4th 50A capacitor blew (to the left of the inverted power coil)

All joking aside, it could be any number of reasons why it stopped working, but the definitive test is to use a power supply tester (available cheaply on ebay or for £9.99 in Maplins)

What power supply is the best

OCZ, Corsair, Thermaltake, CoolerMaster, Antec (voted 'most reliable power supply' by pcworld france), Enermax, Zalman. Any of these brands should do fine.

Don't buy a cheap one. Expect top ay between $60 and $150 in the US for a power supply)

Also, buy one that has a bit more power than the one you're replacing

How to check if my power supply is already not ''at the limit''?

1 or 2 extra hdds and ram does not require much extra power and your coolmaster should do the job. But if you intend to use a newer graphic card you should check the requirenments for wattage at your new card manufacturer product specification webpage. I am pretty sure that almost all newer graphic cards require at least 500 watt to run without problem. My advise is to buy at least a 550 watt psu although i don't know what is your hardware. Try to post your hardware specs and calculate for each component (cpu wattage+graphics wattage +etc) your power supply need to be over 50 wattage. Hope that helped!

Cooler makes noise,when it rotates.please help.

Stop beating up the tower before you damage the harddisk! If the case/PSU is out of warranty, take the PSU out and get the fan replaced. You can do it yourself, just observe the arrow direction on the fan (usually the round label should point out) and wire colors (the fan should blow out). Observe also all the precautions since the capacitors inside can hold a significant charge.

Power supply does not fit!

OK most PSU's are the same.. by that I mean as long as the output & connections match, then the size & shape don't really matter. On the PSU somewhere will be a "Wattage" rating say 250Watt... whatever.. simply obtain a standard (Usually 350Watt) PC Power Supply Unit (PSU)of the SAME or HIGHER Wattage rating & also ensuring the Mating Connector onto the MotherBoard is the same... ya be all good..
