Please help my computer won't stay on anymore! It loads til the desktop sometimes and then just dies. I don't understand, i've checked all cables and connections, pulled all out a replaced them all but still doesn't help.
Does anyone have any idea of what could be causing the problem?

Probably PSU as stated, easy repair to do yourself
If renewing a PSU check:
1. The physical size of your PSU, some are hard to replace due to being a non standard size. 2. The amount of power need from the PSU don't skimp. 3 The correct connections for your equipment
1. Physical Dimensions
Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:
# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws. # Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around. # MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX. # Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.
Use the data above to determine if a particular power supply would fit your case.
The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.
