It happens because the power supply is overheats and computer goes to standby. The power supply is 160w or lower. Specially it will happen if you put more devices in such as video card or sound card. So the only solution you have is to place a small 1or2 fans toward the power supply to make it cooler. And 1 more thing the power for the fans should come from other sources.

Check if the capasitors on the motherboard are "swollen" which would mean the motheroard is KAPUT. Check if there is a modem in the PCI slots which often shorts the motherboard (when it has become faulty) ... remove the modem. Try booting again. If not succesfull make sure the POWER SUPPLY workls correctly by replacing it with another working one..... If no joy... there are still one or two other options. Let me know If you still have a problem and I will give you more options to check on
