Power Issues with current build - no post

[efficacyman]

I'm living in an older place with sketchier electrical service to our circuits (circa 1970). My current system is down for the count and I've had one of my three NEC 20GMX2 die on me (looks to be PCB issue) and also a SS4200 (low power intel NAS box) with motherboard issues. I'm looking to see if a double conversion sinewave ups or line conditioner would save me from massive headaches in the future.

I had the current system crash out on me about a month ago - just died, wouldn't post. Tried another formerly known good PSU (corsair 550 watt) with no luck. Traced it down to a short on the front panel usb. Removing and replacing components then allowed it to post and run for a couple days. Yesterday rebooted after streaming media from PC for about 8 hours. Then after reboot, PC worked for about 4 hours and now no POST/anything. I'm thinking its a deeper power issue with the circuit I'm on.


My current system:
2500k - no OC
Thermalright Venomous X cooler
Gigabyte-UD3-P (crap board got nearly free from microcenter)
Seasonic X-750 gold
Sapphire 6850 Toxic Edition
2x Harddrives, 1x optical drive
4x 2gb 1333 mhz DDR3 Patriot Memory
HAF 932


Currently have a laser printer (Samsung 620nd), 2x NEC 20gmx2, system above, label printer, and 2x 13w CFLs plugged into the same circuit.

This IMO sounds like you're trying to duct tape something that needs to be welded. I'd get an electrician out personally. Could be something relatively inexpensive.

I agree that its a larger problem - I actually didn't put 2 & 2 together until I was component shopping for a new motherboard today and got to thinking about everything which has failed on that particular circuit recently.

Any suggestions on what to tell the electrician? I'm not an Electrical Engineer by any stretch of the imagination. I'm renting from the local university - I'd need to have more than suspicions to get them to come out and even then its unlikely I'd get someone very competent.
