PC Restarting Randomly and Taking a long time to start up.
Computer information:
ASRock Mobo M3A785GMH/128
AMD Phenom II B50 or 550 Black Edition. OC'd to 3.4 MHz with all 4 Cores unlocked.
Nvidia 275 GTX
4GB of DDR3
So i Just got most of this stuff for christmas and i have built 3 computers so far but have never had this problem before.When i start up my computer it acts as if it is going to start up but then about every 5 seconds the fan on either the CPU or Graphics card is shot up to the max and then slow downs and then speeds up again.. It does the about 10 times before the computer finally turns on.
The other problem I have is when i am just surfing the web or playing a game, just about anything, my computer will just randomly restart itself. It doesn't prompt me or anything but it happens the first time i turn on my computer then restarts and it never happens again.
Hopefully someone can help =/
For some reason when i start up the computer

I had something exactly like that and it was a bad plug connection,so check those plastic plugs.
I am not sure why your fan wants to work at max,that would be a program doing that because i believe fan settings are defaulted,they are not variable ,example it would be working at 60% speed and never change unless you had a program that allows it to change.IDK maybe your system has a variable fan setting ,i have just never seen one.If it does have a variable setting,then it would only work at max if something is over heating.This could be caused by using bad voltage settings for example,as i am pretty sure you have not overclocked anything as that would have been your first clue to your problem.
Never forget 3 mile Island and never trust a government official or company spokesman.
That was happening to me as well... turns out it was my hard drive - something to do with the heads or the connectors, i forget which, but after a couple of weeks the HD died and I had to get a new one. The damage was caused by it overheating all the time.
Thanks guys im going to see if all of my cables are connected but i have done SOME overclocking but not much to the CPU but i do not have a fun controller installed only on the case ( Antec 900 2) I'm also going to see about getting a new hard drive aswell because that could also be my problem.
BTW im also running windows 7 32 bit
What PSU are you using? It sounds like either mobo or PSU to me. What can happen at bootup is the mobo has to wait for a clean power signal from the PSU. While it waits for the clean signal it is in a constant state of resetting, which can cause the fans to spin up to max then back down.
Normally a PSU gets the power good signal sent within 50ms but if either the mobo or PSU aren't working right it can take it a while to get started and then be unstable after that.
If the dodgy bootup happens every time, you can use a process of elimination, unplug the hard drive, dvd drive, use 1 stick of RAM, onboard video if you have it, then turn on the PC and see if it does that slow boot up. Also clock down and relock the cores just to be sure that's not causing the problem.
I agree, or possibly a heat issue, like the processor fan is not put on right so it overheats fast.
First check so that your PSU have enough power to run the computer at all. And check so that the processor heat-sink sits right. If it have enough power is my guess that your motherboard is broken.
I'm using a corsair 650 Watt PSU. I'm going to try what you guys said though. And it's definitely not a heat issue though at the highest performance the CPU is still sitting at 27 degrees celcius. Plus i have 5 120mm fans a one 220mm fan so im doubting that over heating could be the issue
I'd lay pretty heavy odds on it being the motherboard, sounds a lot like a similar problem i had on mine. only solution is probably a new motherboard.. at least thats what it took to sort mine out
So after doing everything said above and checking each piece i have found that it is either the graphics card or the PCI-E slot on the mobo. which im leading more to the slot because the graphics card worked great in my other mobo. Ill just have to call and get it replaced. Thanks for the help everyone!
Hmm, still could be the PSU too though, but between the two I'd lean toward mobo. Do you have an old PSU you can try?
Random reboots always makes me suspect the memory first. I have one system that all I did was swap the memory to different slots, and it never happened again. You could download a free memory test program and run it, or set your memory to a lower clock and up the voltage a tiny bit. Also, if you have a voltmeter check that your power supply voltages are within spec. I had a supply that was only putting out 2.7v on the 3.3v line which led to random crashes. If your BIOS has a "load failsafe default" give that a shot as well.
It shouldn't be the PSU i don't think just because i used the same one on an old build and it worked perfect and worked on this new build for about 3 days then this happened.
But i tried switching the memory slots but it is still doing it. I'm going to try what you recommended though and see if the memory is bad. If that is the case i would be much happier then buying a new mobo lol
So it finally stopped... but the thing is i don't know how. I went into the bios and reset them to default (which i had already done about 4 times) and then tried to overclock the cpu and my computer wouldn't start up so it went to the windows start up error solution center and tried to correct it but failed... So i clicked finish and now everything works perfect! No restarts, no long time to start up. I have no idea what happened but it works perfectly now.
