|A couple months ago I started having intermittent power issues (computer would be asleep and when I came back into the room it would be off, etc) until eventually all I could get was a light flicker on the case and the cpu fan spin for 1-2 seconds before power off. Also, I could only get this effect if I turned the PSU off then on again (I could not do it 2 times in a row with the PSU set to on). I figured my old 430W PSU had died after its good 3-4 years of service and bought a Corsair 600W PSU. That one had the same problem, only much faster--I think it only lasted 1 month. |
I can't seem to pin down what the problem is so I bought a new motherboard:
GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard
And a new CPU (not overclocked):
AMD FX 4100 4-Core Processor, 3.6GHz Socket AM3+ FD4100WMGUSBX
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9B
and for good measure, a new case and a new DVD drive (Sony DVD-RW, not sure of exact specs but I can get them if it would help)
The only original items left are the graphics card and the HDD.
HIS H467QS1GH Radeon HD 4670 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card
(I can get HDD specs if needed)
I took all of the components to a shop to have them installed since having so much trouble made me worried that I was doing something wrong. My guy tells me the PSU is bad, that the voltage is fine but it is giving a PG number that was so high his meter wouldn't register it.
The guy installs everything with yet another new PSU:
Cooler Master Extreme Power Plus 700W RS-700-PCAA-E3
Everything powers up fine, I take it home. The computer has turned itself off twice since then so I get a new surge protector and plug it into a different outlet. Last night it turned itself off in the middle of a program and won't turn back on. No lights or anything, flicked the switch on the back does nothing.
If it is the PSU, I'll be on my 4th in 6 months so I would love some help trying to figure out what is going on.
If you need specifications, I am more than happy to provide them but a little guidance as to which ones would be really helpful.
Also, I've built all of my machines (but would still consider myself to be an amateur) and I have never had a problem like this. No one seems to know what is going on--both on the internet and in person at shops.
