Hi, from your description it appears your power supply is ok.

Remove your RAM chips, clean everything with a soft brush or a can of compressede air [from computer store] Reinstall the RAM making sure it is seated firmly.

If this does not solve the problem, Are you using 1 or 2 RAM sticks? if 2 then remove them again and swap them around.

stick one in dimm2 and stick 2 in dimm 1.

If you only have one stick then beg or borrow another stick and try it. If all fails you may have developed a mobo problem.

My cpu fan spins very fast than normal and makes a lot of noise. I use hp d530 cmt- 3.06GHz


Most fans are "temperature-sensitive" -- if it is sensed that your computer is close to over-heating, the fan will run at full speed, very noisily, to try to cool it.

So, shut it down, and disconnect the AC power.
Remove the side-panel.
Purchase a can of compressed-air.
Give the computer a "blow-job", to remove excess dust,
since the layer of dust is acting like a blanket,
keeping heat inside your computer.

Emachines w3507 power


detarch all accessories or hardware connected to the system , then bring out the power pack itself out completely look for a soldering led to test the functionality of the power pack itself if it rotates the fan of its pack by looping the first hole to the third hole cable in the power pack connector that will head into the motherboard. therefore, check the mother board if there is any damage on it like some component if all this is false . then plug the power pack to the outlet and fix the connector of the power pack to the motherboard after detaching both cd drive , floopy disk drive leaving the hard disk and the memory . then change the memory card and press on the system there should be a solution from all this . the problem should be from the Memory not to be able to start up the system but go through those process i have given you before concluding it was the memory ok....


kindly rate this solution......

Motherboard won't boot: no noise, no nothing...


Shorting the two leads will work but don't keep the two wires together. They are not ment to stay connected. Consider replacing your cases ATX power switch. Take a look at the link provided for a new switch;
http://www.cables4computer.com/Cases_and_Enclosures/Mid-Tower_PC-Cases_ATX_Push_Button_Power_Switch.html

The green LED on the motherboard means the board is in "Stand by mode". This green LED uses 5V DC to light the LED. After replacing your PS back into your system it may function just fine.

Good luck.

Hp530 Ultra Slim starts and stop after 3-20sec


I have had this once before, and then it was one of the hard disk cables which was interfering with the fans inside the case. In my PC it was the PSU fan which was being halted. Try moving the cables around inside the case and ensure none of the corners where they are folded are protruding into any of the fans.

How to hook up the front panel switch for a Quicksilver2-cmt motherboard

locate these and let me know what make and model and i can do my best to provide you with the manual.

Thanks,

HP D530 Will not start:


It can't be the RAM, it would be beeping if the RAM was not installed properly. If it was and they were bad, it would fail in Windows.

We've had numerous similar problems to yours with our D530's. Check the motherboard to see if any of the capacitors (round barrel shaped components) are swollen (round on top) or leaking. It is a known manufacturers defect and they were replacing those motherboards for free, unfortunately that program just ended.

If the capacitors are all flat on top, its probably the power supply. We've had four go bad in the past month. They sometimes smell like something is burning before they go bad. The D-530 model is unfortunately our most unreliable model ever, they are junk. Good luck.
