Answers :

Your computer has been damaged by lightning. The power supply passed some of the surge on to your other components and damaged them too. Without checking every component it is impossible to tell everything that was damaged, but most likely the motherboard since it is the next thing the power supply touches (along with your hard drive and optical drive.)

Take the computer apart and test every component (motherboard, memory, and drives) with known good components. Even if they test good, an electrical surge might damage them so they only work sometimes and it might be very hard to tell if performance will be satisfactory all the time.

Post back with your test results.
In addition to your power supply, your motherboard was also probably affected by the surge. Most surges do damage beyond the motherboard. The power supply is still supplying power to it, which is why the fan runs and power lights come on, but it probably isn't doing much more then that. You might want to start looking for a motherboard replacement. The best and most inexpensive place is www.tigerdirect.com.
