It is most likely the processor fan which is getting busted or dirty.
Open the machine after having it unplugged and blow it all dut in machine and from both fans. Clean the fans with a soft brush and see if that works. Otherwise you will have to replace it. But normally it is just dirt

SOURCE: HP Desktop power up problem

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.

I had a similar problem. Moved a 4-year-old desktop. Got the flashing light and no start. Quick fix is to unplug unit, open up case and unplug the large power connector on the motherboard. (On mine this is marked P1 and has a lock tab on one side that must be held in while unplugging.) Plug the 110-volt power and THEN plug the connector back into the motherboard. Button the case back up and all will be well until the next time you shut the power off to the computer.

The cause of this problem is likely that the battery on the motherboard is nearly dead. The flashing light is a warning to replace the battery. (It would have been nice if they would have put this into the user manual.) When you disconnect the power as described above, you interrupt the low-battery circuit. Replace the battery and all should be well.

Hi there,

You have mentioned that your computer works in safemode. This means that there are programs that starts up with windows that is causing this problem. In safemode, click start then run. In the run box type msconfig then click ok. At the startup tab you will see the programs that starts up with xp. Try disabling some or all of them (trial and error) to check which software gives you this problem.

My pc is locked in hibernation mode, I think. Powers up, but mouse and keyboard won't respond. What should I be doind? Frustrated.

The best solution I have found for this problem is to remove the hard drive and attach it as either an external drive or internal secondary drive on another PC.
Once your PC has booted up click on the drive in my computer, making sure that it is the secondary drive and not the primary which is usually called drive C.
Make sure your files and folders setting is unchecked in the area called hide extensions for known file types, and hide protected operating system files. This is found by clicking the tools tab on my computer, then folders, then view.
Now find the file called hiberfil.sys in the root directory of the hard drive from your malfunctioning computer and delete it. Turn off the PC, remove the drive and reinstall it in the original PC. You should now be able to start windows properly.
If this method is too difficult or impossible for you to do you can also obtain a copy of Ubuntu and run your PC from the Live CD version. Then you can simply find the drive in the drives directory on Ubuntu and remove hiberfil.sys that way. Restart the PC, after removing the CD and all should be fine.
