Hi, i'm the cousin of GIBSON (sorry for my english if i mistake :d i'm only 15)
well, now i have problems again, after i boot my pc he does just fine untill everything is loaded and i'm on my desktop then after a minute he reboots en NO SIGNAL on screen , my mouse an keyboard are out 2, but now i booted and directley launched a game i could play for a 15 min. then the same problem i don't know wot it is but want to see it go away:D what could be the problem??
tnx iiNferNo
Welcome to Bjorn3D's forum!
The problems you describe could indicate a loaded PSU.
What is your system spec? (include your PSU).
It also could be connected to overheated CPU, check the temps of your CPU on startup.
Good luck, keep us posted.

Can't be the TEMP. its cooled enough and stays in the low 30's
geforce 7900 GT , core 2 dual 1.86, 2gig Kingston, hdd sata II 320GB, Asus P5B deluxe and psu SEA01 Seasonic M12–600 Modular Power – 600 Watt

My cousin made a little mistake, it's a Seasonic 600 watt S12. ;)
Personally I've been thinking about the psu being faulty as well. But then again, it's not really when it's being stressed or anything. It just hangs during boot. Made a few changes a week ago and it has been going alright uptil now. Now it's having the same issues again.
On a sidenote: Last weeked I stressed the machine with S&M stress test. It seemed to be holding on just right so we left it alone for a while. When we came back S&M had stopped and had popped up a message saying the 12V rail had reached 14.95V which seems pretty much impossible to me (I can't imagine it still working if it would have been put under that kind of voltage).
One more thing, the psu fan is having pretty low rpm's (around 750 rpm). Duno if it's supposed to run at that speed or not...

Can i help the problem with the PSU or do i need to send it back for a new one??

Sounds like PSU to me.
Maybe you can come up with another PSU to replace yours and test the system...

That's the problem, it's not like we own a hardware shop like a few of the members here :lol: So we can't just take something and plug it in. We need to be sure about things before going out and replacing or RMA'ing stuff...
That's the point, you can't be sure unless you have another PSU to strike out the option.
Otherwise, you can't be sure of anything...

well, i have my old pc's PSU left but don't know if it would be wisely to be used it on my NEW pc!!

Did your cousin try your PSU to see if anything changes?; after all you are family ;)
If trying another PSU doesn't help try running either memtest86+ (http://www.memtest.org) or memtest86 (http://www.memtest86.com) as it could be faulty memory.
Memtest86+ download: http://www.memtest.org/#downiso
Memtest86 download: http://www.memtest86.com/#download0
Memtest86 Installation Instructions: http://www.memtest86.com/#install
If you are running dual channel memory make sure to only test one memory stick at a time.

Try another power supply and if it still does the same thing run memtest86 or memtest86x as it could be fault memory.
Memtest86x download: http://www.memtest.org/#downiso
Memtest86 download: http://www.memtest86.com/#download0

It's a half-hour drive, and to be honest I don't feel like disassembling my main system. I can't have a lot of down-time as the internet is routed through my comp to my mothers comp and she needs it for business...
You just made me think about something. Maybe we should try to run it with only one stick in. I thought about that last week, but i first switched the sticks to the adherent slots and that did the trick at the time. So I didn't try only one at that moment.

Yea would think so 2 , but don't know wot psu to use but.. the one from my sis' pc u know GIBSON :p she has a new one (new ... a few months she's been usin' it maybe that would work) or not a good ID??

You would have to know it's wattage and it needs enough juice on the 12V rail for your gfxcard, unless you were to put hers in as well...

You should be using a router or at least a hub so your mom's computer doesn't need to depend on your computer for an internet connection ;)
A 30min drive is nothing,.... common now ;)

Your memory or memory slot caused a short. One of the symptoms is as below...
"There're signs of power-supplies being overloaded for one reason or another. One of the most common signs for marginal/in-sufficient 3.3V + 5V combined power is the inverse level up shifting of 12V instead of dropping.
When 3.3V and 5V get loaded down and dropping downward, 12V level will shift upward (-5V and -12V will be more negative!!!)."

First off, thanks for helping out nam-ng, I appreciate it!
The information you bring into play does seem very interesting. I do have a few questions though. How come the problem only shows after a few minutes (i'd personally expect a short to give problems from the moment there starts power flowing). And a second thought, what could be shorting it? I of course can't check at the moment, but I can't believe there's something in the slots. Or do you mean it being shorted on the backside of the motherboard? Or could a bad ram stick be causing shorts?

It could be that one stick is not seated right but I am not sure. Any that case reseat both ram sticks.

I would check the memory first, just use 1 stick and try it. Than take that stick out and try the other. If it got better the first time when you moved the memory than mabye your mobo has a problem with that memory.
But after listening to so many people talking about memory problems with DDR2 and Intel I think there is a better chance of memory probs.
Its not impossible that the PS is bad but I bet its a mobo/memory prob.

First off let me warn you - Stop testing and doing things you don't have sufficient comprehension of.
Defective components causing "marginal/in-sufficient" power can kill the mobo, the CPU, or anything... The simplest explanation found on the net for that is HERE (http://bjorn3d.com/forum/showthread.php?&t=9921).
Bring the memory into a shop with memory testers, memory testers can't be damage by defective memory. They are normally made to check for functional and catastrophic failures.
Check the memory slot for bent contact fingers, they don't have to be power pins to cause major problems.
Memory are made with billions of transistors, less than 1% are active at anytime in use and draw little power. The bent contact fingers can make tons of them to be active all at once when addressed and cause temporary power surges or peusdo-shorts.

Ok, tnx all but it seems its ok for now i've started my pc in safe mode let the anti virus run & now it works just fine. maybe it was a virus? but anywayz tnx and if something would run wrong again I can count on your help :p :paw:

That's great, but I suggest you check and verify the 14.95V reported for accuracy.
No virus can alter voltage regulation no matter how l337 the virus writer was, because voltage regulation is external, hardwired, and not programmable...

I really doubt the system being OK again. There really is something wrong about it, viruses have nothing to do with this whatso-ever.
I don't think the ram is having compatibility problems with the board as Asus claims that the board is specificaly designed to work with Corsair's Hyper-X line. There might be a bad stick in there though, My cousin said he tried to boot it with one stick and it wouldn't even start. So that does sound quite likely, I can't confirm that everything was right though as I wasn't there when he tried it with one stick...

Now he starts up just fine and no problems but if something would happen how can i verify that Vcore problem?? (not a computergenius :p):lol:

There's nothing wrong with the vcore. Problem might be one of your ram sticks causing a short or the motherboard having a bent pin in one of the memory slots...

Hi well now my pc doesn't block when i start up but sometimes after i'm like gaming for half an hour or when i change games it blocks in the new game. example, i play css for a lil' hour and then i change to AOE III and hop it blocks in aoe after 5 minutes but it nevers blocks when it starts up.
what could it be

I am quite curious about this though, if there would have been a 14.95V spike in the system, would it still be running? Wouldn't most of the components be damaged?

Usually it would but not for long.
Wouldn't most of the components be damaged?
Usually not, most properly designed systems would not be damaged. Practically all of them can survive 25% change in voltage level for brief periods but it's not a guaranty that they would.
Exceptions made for the above in systems modified by experts. For example - Some experts had learned from other experts to use cooling fans by bridging 5V to 12V for differential 7V cooling fan power.
In those type of expert modified systems they almost always died instantly and usually in spectacular manner.
