Now i put it together installed windows and the whole nine. But for some unknown reason the computer randomly shuts down. Now the case monitor says the temperature inside the case never goes over 28c in bios cpu is 47c board 38c and mcp is 57c after a random shut down and i restart it. Everything inside the case is cool to the touch except for the north bridge which is slightly warm. The shut downs are random to the sometimes happen while it is booting up, while staying idle etc... The longest it has lasted is about 8 hours but typically shuts down between 30 mins and 2 hrs. Also it is a instant shut down like someone is just pulling the plug on it. All connections inside the case and outside have been triple checked. Could anyone offer any ideas or advice with what may be wrong with it.

I can only think of 2 things that can cause this... since it's an instant shut down... power supply, or motherboard short to the case. Have you tried pulling the motherboard out of the case, connecting everything up, and powering up that way?

If it was a powersupply issue, it just wouldn't turn on. The motherboard is a possibility. Memory is also a possibility. What version of windows are you using?

This isn't true. Many a power supply will turn on and run for hours even if they're bad, then all of a sudden, shut down totally. Poor voltage regulators, transistors, caps, can cause all kinds of problems. I've seen it many times! I doubt memory will cause the instant power loss the OP is describing.

As for the psu, never seen that happen, but that doesn't rule it out.

If you work on a enough Dells or HPs, you'll see it. These guys use PSUs with just enough power (barely squeaking by, really) to run the machine. Real pity.

Actually, after thinking about it, it could be almost anything. The CPU could be overheating, the ram could be shorting and causing a shutdown. I guess you really can't discount anything nowadays.

[MasterGara]

well i was leaning more towards the psu myself as being faulty. like i said it is not a heating issue and if it was most the time it gives you that message" shutting down due to heat" its normally not instant. and everything inside the case is cool to the touch. and the grounding issue i dont think it would run as well as it does with a grounding issue. i am running vista x 64. for the most part i thought that a 950 would be fine for a psu but i guess i got a faulty one and i didn't want to shell out the money for a new one. i all so just wanted confirmation that the psu was most likely the cause. What would be a good one to replace it with . i was looking at the corsair 1000.

[wannabe1]

Corsair power supplies are always a good bet. They're cool, quiet. powerful, and very stable. I use them almost exclusively in my builds.

Another good investment for any enthusiast is a power supply tester. They are inexpensive ($15 to $20) and allow you to check the psu without removal.

[makai]

Well, it looks like you thought it through quite thoroughly. I would still pull the motherboard and run it out of the case... just to verify... more work, I know! I agree with wannabe1, Corsairs are excellent and is what I'm running in all my machines... and they are super quiet!

Your Vid card recommends 36 amps and your PSU is rated (combined 12v w/4 rails) at 67.5 amps. With all things considered, your PSU should have enough power. Perhaps you just got a dud. The PSU carries a "Standard Return Policy" so if it hasn't been 30 days yet, I would RMA to Newegg for a refund and then buy whatever brand you want. If it's over 30 days, you'll have to stick with the Rosewill as Newegg is pretty strict about that.

I will agree with the both of the previous idea's. I bought a new case that comes with a PSU, and it came with one rail dead. It would power up ,but it would have killed other things had I not invested in a PSU tester. Yes this is a very real probability .. As for the mother board shorting .. YUP YUP YUP , another very good probability since it is running and then shuts down randomly, sounds like a short, and it could very well be the PSU's internals doing it. They are new ,but, even the new ones come either DOA , or ,, like in my case , a dead rail . They are what they are , electronics.. Not to say it's a bad product ,but just one got past QC is all ..

[makai]

Yup, that's how it goes. I just built 3 computers recently, including the on in my sig. All components came from Newegg. I was lucky that the only thing DOA was a 600Gb WD drive. I RMA'd for refund and bought a Seagate instead. I always buy Seagates, but wanted to try WD again in one of the desktops, but it was a no-go. Such is the way it is!
