Hi, I have a PC that I am using as my DVR hooked up to OTA and running Media Center Extender to it. I had two hard drives crash twice in the last six months. I also noticed that there was some electricity (could feel faint shocks) when i was touching the PC chassis itself, sometimes. I am thinking maybe it's because I have the PC hooked up to just a surge protector from APC like this. APC Performance SurgeArrest, 11 outlet, phone line (with splitter), coax & Ethernet protection So, I am thinking to upgrade to a UPS. Something like this: UPSforLESS Power Backup Experts | APC BR1300LCD 1300VA Tower UPS If you see the Energy Surge Rating on both, how come the surgearrest(non UPS and cheaper) one has such a high 2030 Joules vs it's 340 Joules. Higher Joules is 'better' I thought. Maybe not? Noob here, thank you.
