HP Desktop power up problem

\015 My HP Desktop (Pavillion) won't power up. It got to the point where it would power up for a second or two. The blue light around the switch would show and then shut down. A few days prior it had started making loud noises. I replaced the hard drive but it does the same thing. I noticed a small fan just below the power supply seems to operate the same way. If I reset power (following the new poweer supply instructions), the fan will poweer up for a second or two, I see the blue light for a second or two and then it shuts down. Per the instructions if I turn the power supply switch off (the new power supply has a on/off switch) and disconnect then reconnect the connector to the mother board, then turn the power supply switch on it runs for a second or two. Any ideas?\015

Answers :

Bad ram probably, units do that all the time at my job. Most of the time, it is the power supply that does not have enough power to invest into all hardware that makes your pc. even if you had a 400watts power supply, the next time you are buying a power supply you should do some kind of upgrade. 600 watts or more. If you have a high end graphics card then you are indeed in need of a new power supply. also check your cpu, its fan, check if it still seated properly, if there still paste on top of it to hel cooling it down, and protect it from statics. if you added new hardware, remove them and keep checking if it is working. To do manual diags, you need to take the unit apart. I would start by removing rams first, and check ram one by one, then hdd, then disconnect other components until i find the actual part. I am sure it is your powersupply, worst case scenario is you mobo is gone.(but it powers up and shutdown after all so let us hope you don't have a dead motherboard." and remove the dust please, dusty units do not run properly.
