CPU Upgrade, but computer won't work anymore!

Adrianjc7 · Jan 5, 2014

Hey guys, I have a quick question that hopefully you guys can answer soon, as I'd love to upgrade my CPU.

Here are my specs:
I recently upgraded from:
i5-2500k
TO
i7-3770k
(Link - http://www.amazon.com/gp/product/B007SZ0EOW/ref=oh_details_o01_s01_i01?ie=UTF8&psc=1)

Motherboard: GIGABYTE GA-Z68XP-UD3P LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
(Link - http://www.newegg.com/Product/Product.aspx?Item=N82E16813128506)

When I tried installing the new CPU (i7-3770k) it seemed as if it would start just fine. The cpu fan would turn on, but the screen would stay black and after about 8-10 seconds the computer would turn off. This would continue over and over unless I unplugged the power.

Any help would be appreciated, thanks in advance!

What psu do you have?

k1114 · Jan 5, 2014

Try to reset cmos. Did you update the bios?

Adrian Ocampo · Jan 5, 2014

Check if the current version of your bios supports the 3770k. There are some updates that would be needed if it werent supported.

Turtvaiz :

How exactly can I see the without opening the case. Is there somewhere in the device manager I can see maybe?

Also, I'm pretty nub at computers for the most part.. where exactly would I update the BIOS?

k1114 · Jan 5, 2014

Since you didn't update the bios, it's safe to assume that's the issue since the older version won't be compatible. You can download the bios from the gigabyte website, get version f7, but you will need to install the i5 so you can turn on the pc. http://www.gigabyte.com/products/product-page.aspx?pid=3912#bios

Thanks for providing the links.

I will get to this and try it tomorrow after work and let you know if it worked.

Turtvaiz · Jan 6, 2014

Adrianjc7 :

You need to open the case to see that >.> I guess you bought a OEM "Gaming" PC

Adrianjc7 · Jan 6, 2014

I built it, but I have completely forgot what I've used, lol.

I'll be updating the BIOS in just a little bit, so I'll let you guys know if it worked.

Adrianjc7 · Jan 6, 2014

So before I do this, let me get this straight. Download the F7 while I have my i5 connected? Then after that is done, replace the i5 with my i7 and it should work fine?

jock1092 · Jan 6, 2014

First off sorry if this may sound bad but check that no thermal paste has touched the bottom of the cpu or the socket. A friend called me to check they're pc after upgrading there i3 for an i5 with the same problem your describing and that was the cause, all we did was clean it with some isopropal alcohol and let it dry and it saved a big headache.

k1114 · Jan 6, 2014

You don't just simply download it, you need to update the bios. If you have @bios installed then you can update it in windows, otherwise you can use qflash. http://www.gigabyte.com/webpage/20/HowToReflashBIOS.html Once the bios is updated, then you replace the cpu.

Adrianjc7 · Jan 9, 2014

Tried doing what you said with @bios. Downloaded the f7, plugged it into @bios to update. Them after it installs, tells me to restart the computer so I do. Now when I restart it goes to loading operator system "BOOTMGR is missing, ctrl alt delete to restart"

Now my computer is completely out of use.

Adrianjc7 · Jan 9, 2014

Ok don't know how I fixed it but I managed to get back on my computer. I changed the boot sequence in BIOS and chose a harddrive. Now I am scared to touch anything, how exactly can I update my BIOS to F7 without it doing this again to my computer?

Or do I actually have F7 on one of my harddrives and now if I replace my i5 to the i7 will it work?

I'm so confused.

Adrianjc7 · Jan 9, 2014

Actually, just looked to see what version of BIOS I have and I found this.

chrisso · Jan 9, 2014

When you installed the new bios, you lost your old boot sequence settings. Nothing to panic about.

Adrianjc7 · Jan 9, 2014

Scared the shit out of me.. lol PHEW

Ok, so now would I be able to swap my i5 with my i7 and it should work?

k1114 · Jan 9, 2014

When you updated the bios, it's default settings which defaults to checking ports sequentially so your boot drive isn't in the first port. It's not an issue as long as you just change the boot sequence.

Now that it's updated you should be able to change the cpu and it'll work.

Adrianjc7 · Jan 9, 2014

Thanks, I'll give it a try in just a minute and let you guys know.

One question that might be off topic, but how much thermal paste should you put on the CPU when you install it?

Adrianjc7 · Jan 9, 2014

I have a new problem... I think. I have turned off my computer, unplugged everything, out in the new i7 CPU and turned on the PC. Now I have a problem of my monitors are black? The computer is on, runs fine, fans are on, but my screens are black.

Any ideas?

Adrianjc7 · Jan 9, 2014

Nothing seems to work at all. No mouse, keyboard or anything..

Adrianjc7 · Jan 9, 2014

I hear the beeps as the computer starts as well..

The PCU I am using is a corsair hx750

Adrianjc7 · Jan 10, 2014

Anyone? Would LOVE an answer, this is so frustrating..

Just put back in the i5 and the computer works fine. What is going wrong, someone please advise.

k1114 · Jan 10, 2014

It's probably just not auto detecting the cpu change. Reset cmos. What beeps is it making?

Adrianjc7 · Jan 10, 2014

The default beeps, I'm not sure. Do I count the beeps?

I tried resetting the CMOS (Taking out the battery, waiting 3 minutes.. putting it back in).

I'm doubting it is the PSU.. the computer fans and everything seems to work fine internally. The things that are not working are the monitors, keyboard, mouse, etc.

I mean, I DO have the I7 BIOS installed right?
