If you have a voltmeter, stick its probes into an outlet set on something like 200 volts, (and AC volts, may look like tilde).
Most equipment will run down to 100V with occasional problems, some require at least 115 volts.
You may have gotten power spikes if other places are having problems also. This can do nasty things including corrupting printer drivers and making computer related equipment into doorstops.
Try turning off everything else possible including air conditioning and read the voltage. If it goes up to at least 110 volts, test the machine again on a clean boot of everything. If it works you know what the problem is. Then for gosh sakes turn on the air conditioner and the lights immediately.
There are power line conditioners, really resonant transformers that will give you 120 volts out with an input of anything from 90-130 in. A 1000 watt unit will run about $1,000. Careful of your fingers, they run very hot. The less load the hotter, counter intuitive. I have two somewhere, they are also very heavy.
