PC Struggles to power up when cold - left off for a few hours

col_rox
Hi, please help. When pressing the on button on my pc first thing in the morning it ticks over rapidly, i can hear a fan turning, the green lights on the keyboard and front of the pc blink rapidly but the pc will fail to turn on. It will finally power up after holding the power button whilst flicking the power supply swich at the back - after several attempts. Once the pc has been on for a while it will switch off and on okay. This morning used a hair dryer to try and warm the pc up, and it started after afew attempts - this is not very practical though!

    I had the same problem a few years ago. What I did is to switch on the PC Go make coffee, drink it and then try it again. This problem only happens when it is cold and in africa we dont really get cold days so I ignored it until lightning fixed it for me.

    In your case i would try a different power supply and if that does not work a new mainboard.

    Hope it helps

    find out you need a new motherboard as well.

    I would suspect the power supply is failing. It could short out instead of ust failing. If that happens a new motherboard might not be the only new component you need.

    This is a very common problem with No Name Power Supplies they just fail to put out enough power and cause problems like this. Once you get them started properly they will run OK till next time.

    The problem here is that when they fail completely they are likely to do much more damage to the internals of the computer so I would suggest that you replace the PS now with a Name Brand Unit. A 250 W Antec will be as powerful as a no name 450 W PS and far more reliable so don't skimp on a PS buy a good one and you'll be forever grateful.

    I've seen one of the cheap no name ones allow mains power inside the case and then out across Network cables destroying everything connected to the Network at the time.
