You might try a UPS to help condition the power a little bit. Or perhaps a surge protection device (UPS might be favorable)
they have a UPS, one of these cheap APC 1000 VA jobs, not a true UPS. After a week of turning of and sometimes coming back on, the Monitor is dead. The funny thing is, they work fine for a month or so before they go bad. A 17 inch CRT worked fine for a year.
