Power Trouble starting desktop

[aruntisa]

System Info: MSI (Micro Star) 880GM-E41, Memory Type: 4

x 2GB DDR3 PC3-10600, DDR3 PC3-12800, DDR3 PC3-8500,

DDR3 (non-ECC), AMD Phenom(tm) II X4 965 Processor (be)

with the cooler on it, ATI Radeon HD 5700 Series with

fan and 900 watt power supply. My problems are this.

When i go to start my pc at times it won't start, the

fan on the graphic card will start to spin a little bit

but acts like it don't have enough power to turn over.

my pc doesnt start. I tried swapping the power and

reset buttons, tried unplugging the case fans the small

ones and the large one on the side, i have checked the

wires inside each time and have yet to find a loose one

or cut one, My comp does loose the dvd drive sometimes

almost like the SATA cable looses connection, the power

still works on it but it dont show up under my computer

as even being there. where C drive etc are located....

i will usually have to turn the main power button off

in back for about a minute and try and power on again,

sometimes takes 3 to 5 times before it will start up,

once running it runs great the heat stays down the

power levels look good i am at a total loss and could

use some outside views. thanks for any help....

Well, I don't know what your problem is, but with any luck this will help the people who do have the solution be able to know what's going on.

Sounds like a problem with the power supply unit to me. It might eventually start up but there is obviously something wrong there.

If you do not want to take it to a shop then this [http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm] might be a reasonable starting point. Mind you both of these tests need different tools and if you are not comfortable tooling around with your hardware then a shop is still the place to go.

If you know what you are doing then double check the PSU cables are securely plugged into the motherboard correctly. If you don't know, consult the MB manual or take it to a tech shop.

It does sound like a dodgy PSU however a loose connection can cause these problems.

Sounds to me like a motherboard crack. Causes a whole mess of issues that seem unrelated but aren't. You still have power so the power source isn't the problem. However what everything else runs through likely is the problem. You can crack motherboards pretty easily sometimes just by installing ram or the main power harness to the motherboard. They take a bit of force and if you haven't braced the board it'll crack under load. When it heats up the board can push the broken connection back together from expansion. Which will make it seem like an occasional problem.
