Is my Processor dead?

Hi! I've decided that after seeing all the neat games coming out to build a working gaming PC. My only issue here is that it's not working.

When I first built it I had done everything correctly and placed it in the case, (Keep in mind I never did a pre-test boot to see if it worked.)

The computer would start up, run for at least 5~10 seconds and then shut down automatically, only to repeat the process again until the power was turned off. I've been troubleshooting all the issues and finally decided it was the motherboard. Packed it up and sent it back.

Today my replaced MoBo arrived and I found out how to do a pre-test before putting everything in my case. With confidence I thought it would work this time.

Oh sadly how wrong I was.... the computer is doing the same issue. Restarting on and off, nothing else plugged in, just the core components.

The Motherboard was just replaced and I have a hard time believing I was sent two dead ones.

Please help, what's wrong with my computer and why isn't it maintaining a stable start up?

  2. The only time I experienced anything like this was because my processor heatsink and fan weren't securely fastened down. Though my gut says over heating.

    I'm taking that since you've replaced your motherboard you've cleaned the cpu and heatsink and then re-applied thermal paste ? Cos otherwise that would be a HUGE 'do that', because that would totally cause over heating and make the computer shut itself down to protect the components and would explain the fact that you can wait and then boot up again.

    So step 1... just for the heck of it clean the cpu and the heatsink (acetone (sp?) works well for me if you can't get a specialist cleaner), then apply a small amount of thermal paste (there's tons of videos on YouTube for this that explain the amount visually waaaaay better than I could with words), and reseat the heatsink/fan combo. Make sure that when you do this that all the pins lock down into the motherboard properly. I've had tons of issues with intel HSF pins getting slightly bent after first use and then not going through the motherboard holes properly. Once it's on just check that it's secure it shouldn't move at all (or rather there shouldn't be a very noticeable 'wiggle').

    step 2....boot up

    Still doesn't work ?

    Try running with just one DIMM in place, try this with both DIMMs

    I also recommend reseating your graphics card (just ticking all the check boxes), and maybe checking all cable connections SATA and otherwise.

    Hope this helps a bit.
  3. So I did as you said clean the heat sink and processor of the thermal paste that was on before.

    In all honesty I believe it is my Heat Sink fan not being installed properly or some type of over heating going on.

    I'll try re-cleaning and re-applying this time to see what happens. Thanks for the suggestion.
  4. A dead CPU is HIGHLY unlikely. Did you go through this checklist? I highly recommend you to do so.

    http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems
  5. So I went through the checklist and everything is checked off.

    I still don't know why it's endlessly rebooting.

    I believe my fan is installed properly and I still don't know why it's over heating.
  6. Also regarding your first post, what do you mean by "Only the core components" ? It may be your motherboard rebooting due to the lack of an OS.

    Also, just to be sure, how much thermal compound did you apply?

    http://www.tomshardware.com/forum/338655-28-intel-stock-cooler-installation-guide

    This is also a very good guide I recommend you take a look at. Even if you think you have the cooler installed correctly, due to the nature of Intel's stock heatsink, it may still be loose.
  7. If you have one try another power supply. I built a system a couple of months ago where the power supply failed and went through exactly what you're describing.

    Plus, an i3 on a Z77 board? I would have saved a few pennies and went for an H77 board. You can't overclock an i3 (not as far as I know anyway).
  8. ^ +1 for PSU

    Though unlikely, it is more common to get a dead PSU rather than a dead CPU.

    However, I feel he may have done the right thing getting a Z77 board, it gives him the option to get whatever 1155 CPU his heart desires in the future :lol: However, you're right about H77. It is still the best price/performance chipset at the moment IMO.
  9. Hahaha, I'm so stupid. My RAM wasn't installed correctly. Anyways thanks for all the suggestions and help. My computer should be up and running very very soon.

    And @Pauls this is my first computer, cut me some slack :P I was on a budget first and foremost and don't plan on OCing anything, not until I'm at least a little more knowledgeable in that area.

    :lol: Glad to know you got the problem figured out! Good luck and have fun! :)

    Also on a side note, if this is your first rig, you did a GREAT job!
  11. Thanks for the compliment, but as always there's still one more issue I'm having. No POST or BIOS screen is appearing. Arg....
  12. Do the fans spin up? Which port did you connect your display cable to?
  13. All the fans spin up yes. Everything runs to what seems to me as fine.

    My HDMI Cable port is that's what you're talking about.

    Sorry for any misunderstandings I may have brought up, I meant which port did you connect to (motherboard or GPU)?
  15. Oh, my motherboard.
  16. urbanemp said:
    Oh, my motherboard.

    Hook it to your GPU and see if you see anything on your screen :)
  17. Am I missing something? I don't see where on Earth I'd put an HDMI cable on my GPU.

    This is a picture of your GPU's I/O from newegg.


    If your GPU doesn't have an HDMI port for some reason, try connecting it via DVI :)
  19. urbanemp said:
    Ah... crap I don't know what cable I'm suppose to put there.

    Haha, guess I'm not as good at computers as I thought. D:


    Nothing to worry about, these connectors can get the best of us :lol:

    Did your card come with a DVI->VGA adapter? If you have an old monitor laying around, you could use that.
  20. urbanemp said:

    It has a mini HDMI port, but it looks like that particular card didn't come with an adapter to covert it to full size HDMI (bad on EVGA's part. My Asus 560 came with one...).

    Now that explains OP's troubles :lol:
  23. So let me get this straight. The HDMI plugged into my MoBo is suppose to go into my GPU with the use of a converter or in other words a DVI->VGA adapter?

    Because I do not have an adapter on hand.

    Yes, if I'm understanding you correctly (the HDMI cable that is currently plugged into the motherboard should be plugged into the the GPU with the mini HDMI to HDMI adapter).
  25. The HDMI ports, or any display port on your Mobo will go straight to your IGPU on your CPU.

    I was recommending the DVI->VGA adapter in case you didn't have a DVI cable or DVI monitor :)

    Rather, what I'm trying to say is, do you have any monitors laying around that don't need HDMI? If you do, use the DVI connectors on your GPU.
  26. Your CPU has a graphics core on it, and if you use any connectors that output video on your motherboard, they won't output any video from your GPU.

    ^ This

    I can't speak/type tonight, long day, pardon me :lol:
  28. urbanemp said:
    Well, in other words can you show me what I need to buy from like Best Buy? I have no DVI monitors on hand.


    Something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16812270287
  29. I'm really sorry, you lost me at "Display port on your mobo will go straight to your IGPU"

    My bad for not understand this very well, haha.

    So my HDMI Cable, I leave that in?

    Well, in other words can you show me what I need to buy from like Best Buy? I have no DVI monitors on hand.

    So it's just more plugging in to plugging in essentially? There aren't going to be two cords coming from my Monitor into my Computer, correct?

    Correct.
  32. http://www.newegg.com/Product/Product.aspx?Item=N82E16812270287
    :) Don't buy from Best Buy unless you can get a reasonable price...they tend to overprice the **** out of things from personal experience.

  35. First off, thank you guys. You've been the best of help and excuse my ignorance on the computer subject. Wish you guys were here with me right now to help me out Haha.

    Being 15 years old, computers are pretty hard to me. Love the fact I've made so much progress though.


    I hate to say this but I haven't been using an HDMI cable this whole time. I don't know what cable it is, to be honest.

    When I looked at the back of the converter I realized that I'm on a totally different cable.

    My best description of it is that it's blue and has two screws bolted onto the sides of it.

    Most likely VGA from the looks of it :)

    On a side note, did your video card come with anything that looks like this? http://www.newegg.com/Product/Product.aspx?Item=N82E16814999201
  37. Yeah, it's probably VGA and in that case, the card did come with a DVI to VGA adapter (it's in the pics on Newegg, anyway).

    Edit: Connect the adapter to the bottom most DVI connector (at least that's how it would be on my card, and I would think that it would be the same for most cards).
  38. I'm honestly going to have to relook through the packaging. I do not remember getting any thing that was a DVI To VGA adapter.

    Anyways, it looks like I'm going to have to buy the picture you posted above Molook, unless I'm mistaken?
  39. Hopefully that's the case so OP can get his PC up and running (finally).
  40. I bet you do :lol: the thought of me not being able to use any new components will just kill me.

    Anyway, look through your boxes and if you can't find a DVI to VGA adapter, I recommend you purchase the one I linked above.
  41. Haha, believe me I want to be done with this computer so I can finally play Guild Wars 2 and Planetside 2.

    If you can't find the adapter and you're talking about this http://www.newegg.com/Product/Product.aspx?Item=N82E16814999201 then yes.
  43. Time to search for the adapter and hope I find it.

    Anyways thanks again guys, you've been such great help.
    You'll either get a thank you message from me if my computer works or you'll be (Hopefully not) seeing another thread from me.

    Let's hope for a message shall we? Haha.
