However the computer power supply remained on etc, but there was no display to the monitor and no evidence that start up had occurred. As normal I switched it on with the external button and like yesterday the chime failed to sound and the computer failed to start up. Today I adopted a different start up procedure. It then continued to run without a problem.
Eventually the chime was heard and I was able to start the computer successfully. Several attempts to start the computer failed for the same reason. Yesterday when I switched on the computer the start up chime failed to sound. I would like to update you about this matter. And when the computer is on it works a treat.ĭoes this sound like the PSU is dying/dead? I thought this could be an easy software fix, but am now chasing the hardware train.Īny help would be greatly appreciated and thanks in advance! I have no red leds on the logic board lighting up, so no obvious failures. The only main components left really are the power supply and the logic board. Tested all the ram (6gb), moved them around etc, no red dimm lights on either board.

I managed to install snow leopard from a DVD onto it before a crash and the computer worked for maybe 20-25 mins then it blacked out again. I tested the computer with a 128gb SSD which i know worked.
The computer has a WD velociraptor 128gb 10k rpm HDD installed. I also tested the gfx card in both available pcie slots aswell as cleaning out excess dust from the gfx card using compressed air. But my macbook pro hits 75 C on the CPU when using intensive software (logic pro etc). Infact on monitoring all the temperatures when the computer was on i noticed no abnormality with any temps apart from maybe the north bridge which was max 62 C when idling. I tested the temps on the gfx card and they were not abnormally high at all. Originally i thought it might of been the graphics card (Nvidia 8800 GT) which upon researching had found out there have been issues with this graphics card for other people in the past, however they speak of glitchy graphics, over-heating and 'baking' the card. This shut down can only be stopped by hard resetting the unit.

Sometimes it would happen more often when say I watched a youtube clip on full size in 720/1080p.
This could happen before the computer boots, or could happen 15 minutes later. On turning on the computer myself I soon saw what he meant, all of a sudden, quite randomly the screen would drop out entirely and about 8 seconds later the fans go on full whack. I bought it cheaply as the original owner claimed it had a problem where it would randomly sleep, and a hard reset was neccesary in order to restart the computer. I have a Mac Pro 3.1, 2008 dual 2.8ghz computer.
