FIXED: New PC build won't stay on longer than 5 seconds!!!!!

[Video Head]

I have seen British AC Ace's with Ford 260's, 289's, 427's and 429's in them. One might have even been a side-oiler.

Well the main thing to see if your CPU is bad is what gets displayed on the screen ?? If its active for five seconds(?) you should be seeing something about post and ram testing etc etc. If nothing gets displayed on the screen then perhaps it is the CPU. 5 secs sounds like enough time to warm up to critical temp and then shut down. This may or may not be erroneous. If the CPu is truly FUBAR then the PC will shut down instantly/fail to power on.
I would check CPU heatsink, Fan and Fan connectors to MB.. whether 3 or 4 pin or RPM controlled.??

I had a friend way way back in highschool that had a VW bug with a Porsche engine in it. I've seen Beetles, Karmann Ghias and Corvairs with small block chevy engines.

If memory serves...

Those Porsche-engined VWs were "polizei" versions in Germany, and it was awhile before it became general knowledge they had them. Imagine the surprise of motorists seeing one of those on the Autobahn at full speed. :P

All CPU manufacturers have down-binned individual processors since day one. That's how they maximize yield (and profits) from each wafer.

Exactly, which is why it makes sense to buy a base speed cpu from a manufacturers premier line early in production before the build up a stock of low yield wafers (that is if you are into over clocking)

Yep!!

Bad CPU!!!

I received the replacement earlier this afternoon, fired right up, installed XP Pro x64 & all is good.

Just my luck i would get the 1 in a million new bad CPU

By the time i posted i was already to the point of assuming it was probably the CPU but figured i may as well try because ya never know.

And i did get some other good ideas of what it could be that never occurred to me.

Thanks everyone for all the brainstorming & help.

After 10 years, the law of averages caught up to you.

Glad you got it fixed.

[Noahtuck]

Thanks!

Yep... hopefully it will be another 10+ years

What a PITA

Good to hear you got a replacement cpu and all is good!

[greymalkin]

this is good to hear..I have a desktop that is behaving the same way..one of the clips broke off on the heatsink so I used a plastic zip tie to hold the spring arm down, but apparently it isn't doing the job right b/c it's powering down randomly after a few seconds of use . The heatsink mount is part of the motherboard though so It looks like I'm stuck! oh well it was an old desktop anyways...

Buy an aftermarket heatsink and fan that screws to an adapter on the back of the motherboard. Hopefully you haven't fried anything already.

Gotta replace the bracket with a gigbyte one cause a lot of them are custom built for the mb,if the heatsink was good enough then you dont have to replace that if it didnt get broken.
