Is this a PSU issue?

[mattlef]

Alright, to sum this up I'm having issues with a hard crash, where the entire computer literally turns off. doesn't bsod or anything, and happens in 2D as well as 3D.

Hardware:

CPU: 955BE
Mobo: MSI NF980-G65
Ram: Dominator 1600 DDR3
GPU: 2x 460 768mb
Cooling: h50
HDD: WD 320GB Blue
Optical: Samsung Sata DVDRW

PSU: XFX 650w XXX

I was playing some SP BC2 and it just shut down, restarted, checked gpu fan temps and speeds, adjusted the fan speed and crashed again. This did not happen when I had my Enermax 620w psu attached.... at all, ever.
I think maybe the PSU is faulty or has a short somewhere?

-Edit-
just put the two 460's at slock clocks, ran furmark, same thing.
I think the PSU is defective.... unless any of you can think of any ideas...

-edit2-

Just crashed again on 2d.... not good.

any chance you could swap yer enermax back in?

2d/3d crashes..hmm...how is the ram passing memtest, you say temps are fine, how about mobo temps?

interesting choice of board, as well.

Damn, Temp2 in speedfan, which i beleive is the the nb, is 93c..... really hot.... Vregs are hot to the touch as well....

Easy to test. Get occt and run for an hour. 10 mins in it will shut down.

1. Check mobo (voltage levels) 12@12, 5@5 and etc.
2. Could be psu.

checked around, looks like my NB is overheating, MCP chip right now is sitting in everest at 115c and in speedfan at 95c

[Soultribunal]

Get an Antec Spot cool on it.
That is one hell of a hot Temp for a NB

Called MSI, they say its normal, especially when you're running in sli.
updated the bios, hopefully that'll help with stability issues...

nonono....115 celsius for nb is not supposed to be normal for frog's sake lol!


you need better cooling there, brother. asap. directing airflow at it might not be the best long term solution...lets take a look at your board...hmm...

oooooooooooook


that looks like a fine cooling solution. if it gets that hot, not good. can you redo the thermal paste, well,crap thats underneath? hell maybe they havent peeled off the sticker thingies!


either or, unacceptable.

[mattlef]

Gonna take'r apart tonight. change out the thermal paste and see whats what.

I didn't have much choice in the board, was in a bit of a bind with the EVGA going out on me.... gonna contact EVGA about an RMA on it asap, maybe get intel back.
which seems like a shame really, considering I have a 1055t heading my way.... might look into a crossfire board and see if there are any decent bios sli hacks ;)

i hear the new beta is much easier to use. stil lwiating on a non native sli board to test it(properly) meself.

i say pick up a cheap dual pci-e amd board, 785/790 because of price.
