I need help with my custom built pc not turning on please.....

heyyy, another jimbo look at my last post.


Ugh, I googled my issue, and someone had a similar issue with the pc not booting with 8pin plugged in and it turned out his mobo was "burnt".. which I'm assuming dead. I'm hoping mine is not because it's just such a pain in the butt to replace a mobo. Just an FYI, every fan, light and HD runs with the 8pin plug UNPLUGGED but when it's plugged in, it will not turn on at all. I guess I can hope for the best and try reseating everything AGAIN ..."hey sweetheart, i know what i want for christmas now".. lol my wife will read this because i'm using her laptop atm

also, I don't hear any beeping but I don't remember ever hearing beeping but some website I was reading said you NEED a pc speaker because it could be causing your pc to not boot....???

Are you overclocking the CPU? Or anything other than the Video?

That board has Asus "Anti-Surge" protection circuitry. If you are overclocking, and if you are lucky, that may be all it is!

No, I never OC'd the CPU in this pc because I never really had to. It's the mvp-deluxe with the onboard wifi thing (which never properly worked).

The 8 pin connector powers the CPU. So if you plug it in and the board shuts down then we can assume the protection circuitry is working and there is problem with the power or the CPU or the MB.

Check and double check:

• The modular connection at the PS and the MB. (Do you have a multimeter to test for voltage at the modular output?)
• The CPU heatsink and fan (if you plug the CPU fan into a case header will it spin?)
• The CPU seat. Check carefully for bent pins.

You might also want to try a CLRTC as a last ditch effort. This resets the processor clock.

• Note all your current BIOS settings
• Shut down the computer > remove the power cord.
• Remove the 3v battery.
• Move the CLRTC jumper from pins 1-2 to 2-3.
• Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
• Put the CLRTC jumper back on 1-2.
• Replace the battery > replace the power cord > boot.
• Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.

Obviously the BIOS settings will not apply in your case as you can't boot. But if you do boot, then reset your settings before trying to start Windows.

Good Luck.

thx, i'll give that a shot when i get back home.

well, i tried what you said, and it's still not turning on when i plug the 12v/8pin cable in. i don't know what to do from here... i hate taking my pc to techs because they charge so much for the easiest things. should i buy a new cpu and test it, or a new mobo or both.. ugh, if any of u live in the tampa, FL area let me know lol if you all have any other ideas that might help, plz post. thx again for the help so far. for now, my baby is broke which forces me to watch TV.. booooo!

James,
I'm no computer tech but something in me is thinking mobo. But with a new mobo comes all sorts of questions, plus will it support your existing ram and the like. Did you un-seat the CPU and look closely at the pins, then re-seat and place new thermal compound? Did you blow out the ram connections and re-seat ram? How are you cooling your CPU, stock cooler and fan? Have you test the fan on the CPU?

Yes, I took the cpu out and looked at it, it looks fine however the thermal stuff is very thin and is not covering the entire core (amd phenom BE). I reseat it but i dont have any thermal stuff to add. I am using the stock heatsink/fan that came with it. I also did reseat the ram and blew out the connections with duster, but I have 2 empty ram slots that I didn't try yet... maybe I can put my two sticks in those two slots and give it a shot. One thing that works in this type of situation is you take a pencil eraser and rub the eraser on the gold ram connectors but I haven't tried that yet (that worked for me many times with NEW pc's that wouldn't boot up while I was working for the school board). All the fans in the case, cpu, and gpu's are working when I turn the pc on without the 12v/8pin cable plugged in but once I plug that in it doesn't turn on. Also, when it does turn on (with out 8pin cable) and then I turn it off.. the green light on the mobo blinks many times then stops. I don't really have the $ at all to replace much. This mobo was top of the line back when I built this pc and still sells on ebay USED for $120.00 which is only $20.00 short of the retail price when I bought it lol. This is such a huge bummer for me because that pc is my life, I know the HD's are fine but still. I have an older pc i built but it's much older with an AMD cpu but nothing in the old computer is compatible with the newer one. I'm stuck.

Man I feel your pain. Not sure I have a good next move, they all just seem like educated guesses and they all cost real monies. Is your gut pointing to the CPU? I see tiger has the the 3.4 Phenom for $169.00. Did you know that AMD will test your CPU for free? You should call them and ASUS as MSI was also willing to test my mobo for free. You of course pay the shipping to them and have some down time but that's better than going with costly guesses.

At this point in time, you could try another power supply, or call ASUS about the motherboard. I wouldn't just go dropping money hoping to find the issue.

I did find this statement curious.....

Did you try the 4-pin connector? I'm not familiar with AMD boards, but some motherboards only require the 4-pin connector instead of the 8-pin one. What does your board's manual say about it?

You DID check the manual right? - This would also include the power supply's manual as well.

Yea, I'm going to call ASUS and see what they have to say about this situation. I've googled it and saw that many people ran into the same problem but with no fix. They all ended up RMA mobo or just buying a new one. My gut tells me it's the mobo but I must be 110% sure before I go buy a new one.

I will try the 4-pin connector and go through both the mobo and psu manuals (which, yes, I've done prior to installation ).

If you want to see what I read about other peoples posts on this issue, google "computer wont turn on with 8 pin plugged in"

I'll post as soon as I'm done. Thx for the replies, I really really appreciate your help everyone. Be back later.


James

k, i tried switching the bios battery, i tried using the 4pin cable instead of 8pin and also tried the empty ram slots with both sticks and just 1 stick but with the same outcome. Will not boot at all while the 4pin or 8pin is plugged in, however it will turn on (the fans, lights etc...) when the 4pin/8pin is not plugged in. I'm going to call Asus and hope they have the fix for this. :\


James

WOW, I just called the Asus tech support and got some guy who I could barely understand and after I told him what my problem is, he gave me a 1800# to call Microsoft... ?!?!??!!? I'm like, why do I need to call Microsoft? "Tech: Because it is a software issue and that is the type of operating system you have." I didn't even MENTION a word of what type of OS I had, so I then said; what are you talking about? This is not a software issue it's a hardware issue, isn't this Asus tech support...? "Tech: Yes, but we do not support hardware issues." .... honestly...? So I told him to get a new job and hung up, I then googled "asus tech support sucks" and shockingly there were TONS of hits! lol! But after awhile I finally found a new 1888# which I called and got someone whom I could understand but after I told him what my issue was AND what I had done thus far to try and fix this problem, he goes "hrm.... welp, sounds like you already did all the troubleshooting, here's your case # we'll e-mail you instructions to RMA your MB." k thx goodbye "Tech: Likewise, buhbye."

I'm going insane, even my wife told me to take a nap lol. So, for now I'm going to take a nap then check back here to see if there are any new posts/opinions and then most-likely I'll do the RMA process. Sorry for all the blabbing, but I want to thank you all again so much for your tips and help. I will stick with this website as a regular member! Later

You got a case # and a RMA? Does that mean they are going to replace it at no charge? That would be a pretty sweet deal on a 4 year old MB.

I just read a post on another thread I'm on about a mystery issue that was diagnosed to death that finally ended up being the MB. That conclusion was reach weeks ago. But Gigabyte dicked him around. The first RMA they "checked the board and updated the BIOS", which of course did not solve anything. He just posted that he got them to replace the MB and now all is good.

So my advice is to be sure you get what you expect to be done down in writing in your case file before you send it in RMA.

Always a good practice to take notes oneself and get names and what was discussed and then ask for the case id number and will the notes of the discussion be added to case history. This allows the next rep. a chance to get up to speed and you won't have to do as much repeating. Another hot tip is kill them with kindness, these rep's get yelled at a significant part of their work day and if you keep clam and ask for consideration many times if they can they will. If you need to escalate a problem then ask for a supervisor.

You need to call Asus back and demand to talk to someone more knowledgable as you OBVIOUSLY got someone who either doesn't know what they're talking about, was too lazy to diagnose your issue, or just frankly didn't want to hear what you had to say.

Sorry but anyone with one with a quater of a brain and basic common sense computer knowledge knows that if the computer doesn't turn on, the operating systems doesn't load!!! So how in the hell can that be Microsoft's fault!!!

You accept what you get! Can them back and tell them what the first tech told you and that you want to speak to a supervisor.

And If that tech said that, that doesn't speak too highly of Asus's tech support

My two cents.

Doesn't mean they will fix it for free. You need an RMA# anytime you send something in to the manufacter, it's for tracking purposes at the receiving warehouse.

K good news and bad news and kinda good news,

first the good news; even though I got the board approx 3yrs ago (give or take a couple months) they WILL send me a new mobo once they recieve mine.

bad news; i'll miss my mobo so much because it's awesome, and it will take a couple weeks atleast, probably, to get my new mobo back.

kinda good news; my wife knew how upset i was and came with me to where i get my pc parts and bought me a cheap but a better than none mobo! it's an asus m2n68-am plus. it doesn't support more than 1 gpu (which is bad because I am use to using crossfire 2 gpu's) but it's okay because I won't notice THAT much difference and ALSOOOOO.... she bought me a new logitech mx518 gaming mouse because she felt bad for me. i love her so much hehe.

Above all that, I really want to thank you all again and again for taking the time to help troubleshoot my problem, and after this 4 page thread (sorry about that lol) i'm going to stick around and become a regular member. I'll also link this forum site on the gaming community i own (www.TRHservers.com my alias is vi0lent with a zero). I'm going to get ready to install the new mobo and I'll let you all know how it turns out. Thanks again!

PS - sorry, i know my typing grammar isn't the greatest, somedays it's perfect and somedays i'm too lazy

Sincerely,
James

James,
You've got a good woman there! We look forward to seeing you around the SF.

I know I've done this before but, I really need help with this small easy issue. If I'm correct, aren't I supposed to somehow remove the old thermal stuff from the cpu and add new thermal to it? Or can I just add some thermal to it along with whats still on the cpu? Thx
