Could be a number of reasons.
On an older machine it could be a failing power supply or perhaps capacitor overheats on the motherboard.
For the PSU - download and run everest from majorgeeks.com and look at the voltages - if they are more than a few percent adrift it is time to replace it.
For the caps - a visual inspection of the board will show any that have bulged at the top and are perhaps discoloured, especially those near the CPU.
