Hate to tell you this but strikes nearby come up through your grounding system to take out a lot of electrically fragile stuff, especially CMOS (like the above).
Go with a quality whole house surge protector at the breaker box and also individual protector strips at point of use. Most small protectors use a solid state device similar to a zener diode that shunts excess voltages to ground (and vice versa).
Even better would be a UPS sized for your equipment. I use one UPS per computer (looks like you have more than one). Two brands I have used are APC and CyberPower. There are probably more brands out there. They are very cheap insurance. Find them at Office Depot, Circuit City etc.
Most of the UPS units now available on the consumer market are of the switching type that transfer the load to the battery powered inverter before the output of the computer's power supply can fall low enough to cause disk damage or data loss. That is no were near fast enough to effect most surges and spikes. In order for the UPS itself, rather than any built in filtering or Transient Voltage Surge Suppressor, to provide protection from transient power events it has to be of the continuous duty type were the battery is always in line and the supplied Ac power is used to recharge the battery. If the battery is always in line it is one massive sink for sudden voltage fluctuations. You can get the same TVSS benefits of a switching UPS by using a high quality TVSS protector.
