Ok this might sound funny but could it possibly be the reason?
I've been experiencing major problems with my psu, well atleast to my understanding so far, right now i'm running my running my 3.4 @ 4.01ghz its stable with basic windows user use.. but in prime.. the funny thing is.. today in the morning I primed for like 4 hours and it was rock stable until my roommate came in and turned on tv and then, prime crashed and system rebooted.. in previous tests.. prime won't be stable for more than an hour "while tv is actually on".. today we went out and I said lets take this chance while the TV is off and I ran Prime and it was stable for 6 hours but then gave me a rounding error (so it stopped while the tv was actually off)
the power outlet I'm using for the psu is currently on a splitter and is holding other 7 devices consuming power.. since the outlet has 2x heads.. i figured I'd put the splitter on one and have the psu on the other one.. so i'm assuming it wont be under the effect of the splitter and sharing the outlet (thats what some1 with no background in electricity would think )

so in a nutshell, do you think that it is not the problem of the psu. rather, it is the electricity outlet or somethin like that that is causing this weirdness..

PS. dont tell me to test the psu using a multimeter.. because i've ordered one already and its already on its way

my specs:
CPU: P4 3.4ghz LGA775 (Prescott) @4ghz
Mobo: Gigabyte Ga-8I915P Duo-A
GPU: MSI Nvidia G4 Ti 4600 128mb
Memory: (512x2)mb Corsair DDRII PC5400
HDD: 1x SATA Maxtor 200gb / 1xIDE ATA133 Maxtor 80gb
Cooling: Air (XP-120 with panaflo 85cfm fan)
PSU: Fortron BlueStorm 500w
Monitor: Samsung SyncMaster 710T
Case: X-Blade (Black)
OS: Windows XP Pro SP2
Mouse: Logitech MX 700

I sat the vcore to 1.4875v but it reads 1.408v in cpu-z
isnt that enuf to run 3.4 -> 4ghz ?

wow...that's really odd! i don't know...really the only thing that i can think of is that the tv might be causing some type of interference when the processor is at 4ghz or whatever you were clocked at. if 4ghz is your max...then there is really no for sure way of testing it. mainly because if you back it down to get out of the 'tv' range, then it could also be just instability from the overclock in general.

also....is the tv on the same outlet/fuse as the computer? the tv could be takin some power away from the computer.

no its not.. ;s
its on the living room while my pc in my room.. but I've always been suspicious of the electricity wirings in this building.. as whenever I run the ceiling fan i get a little beep in my surround system.. the same thing happens when turning them off.. isnt that weird?

what I am assuming is not a frequency interference.. rather, a power consumption incapability or something.. I can go higher than 4ghz.. I can go 4.3ghz but wont be stable.. you see I wanna be stable at 4 at first in order to move on to the next step :s

maybe you should invest in a good UPS. prolly be easier than trying to find whatever is causing your electrical problems. unless your just drawing to much from that circuit. my aunt had that problem. her computer would never work at her house but worked fine everywhere else. my uncle was in the process of working on the house and a few months later upgraded their service to 200 amps and installed all new gfi outlets and new grounds.

Have you ever noticed when you turn on a TV the power in other devices(lamps etc) go down for a fraction of a second, well that's because a TV pulls a tremendous amount of electricity at startup, then stabilizes.
So if your PC is plugged on the same circuit, it might have problems sucking enough juice to stay on while the TV is being powered.
Then when you reboots the pc it goes, cause the TV has stabilized.

But i might be wrong

maybe you need to turn on "spread spectrum" or vice versa lol.

I would go with what seth said...I got one and never get any kind of interference...I used to get a little bit when the boiler turned on in the winter and would trow a little static onto my speakers but i got a ups and havent had that problem since...You can get them prettty cheap now...all u really need is one of the personal ones...I got soo much stuff on mine...minifridge, computer, screen, router, 24 port HUB, dsl modem, speakers, and my laptop power thingy...lol...And in the same room i gots a 32inch tv, dvd player, stereo w/ 100W speakers. PS2...and all these things are allways on...I also normally have a server on my ups...and soon I will be adding a 120W bass amp to the collection of appliances in my room...lol....but it sounds like ur PC is loosing power it wants.

Jea, it sounds like power interference. UPS is the way to go, as the others said.


COOKIE!

Things to do, in order:

1. Check the outlet for an Open Ground condition.

2. UNPLUG everything from the wall jack--those seven items are indeed stealing power from the PC!!

3. Install a non-switching UPS so you run solely from the battery.

4. Try a stronger PSU, if all else fails.

GL!

yeah power quality is a biggie, a ups or moving some stuff to a different circuit might help.

Thanks guys..
I will try right now to remove all the stuff first or might as well just get a UPS.. but,
after moving those 7 devices.. should I notice a change in the rails voltage? as the 12v is reading 11.78v now.. should it be more like above 12v .. I mean since its a bluestorm 500w fortron it should be better..
my main concern now is did I just throw 90$ for this psu for nothing? the old generic psu i had gave me quite much the same readings..
