PC takes forever to start up after upgrading to I7 4790K

Beartai · Mar 12, 2015

I upgraded my CPU and mobo recently from an AMD 6300 and an Asus board (cant remember what board specifically) to and I7 4790K and MSI Z87 Gaming mobo and my PC takes over 2 minutes to get into windows, sometimes it loads slightly faster, but the desktop will be black for about a minute before I can start any programs or do anything. Any ideas what could be causing this?

Also another thing, when I go to restart my PC it will power down, but not power up again, it sits in a kind of standby until it is switched off by holding in the power button.

Did you reinstall your windows after swapping your components?

Because you mentioned the second part and the trouble you're having starting the computer up. I'm going to say something is shorting your motherboard out.

Take your motherboard out of the case and make sure every screw is in place. Even one misplaced screw or standoff can cause the motherboard to short.

You can perform an out of case boot also to test this and see if you have the same problem starting the computer up.

First of all, I hope you did a new windows install after putting the I7 in. Second, I hope you updated the bios to a version that supports the I7. These two are the most obvious things that would come to my mind.

to be more straight:
A new installation of Windows is an essential need to do, when changing Mobo and CPU.

Because you´re using an older chipset, you need to have a closer look at your BIOS/UEFI, because the default manufacturers BIOS don´t know this new CPU (Haswell-Refresh).

With the exact model name of your motherboard (there is more than one Z87 gaming model on the market), I could find you the correct BIOS or you search it yourself on the MSI homepage.
Don´t flash in windows!
Download BIOS,
extract to USB thumb drive
directly update it in the BIOS itself, by entering BIOS and choosing M-flash, follow instructions

By the way, did you plug in the 8Pin ATX12V/EPS Power connector into the mother board and not just a 4Pin connector?

Sorry for taking so long to reply, been away from a computer for a week. Yes, I reinstalled windows after upgrading, and I'm pretty sure the bios is the correct version, the motherboard is a Z87-G43 Gaming. Planning on doing a clean install of Windows 7 and Steam OS soon.

BIOS Version is A.6?

did you install all drivers?
use intel update utility
realtek hd codec (audio driver)

in device manager, any question marks or exclamation marks?

do you boot from a SSD or HDD?
check SSD and HDD with manufacturers´ tool
eventually update firmware of the drives

use memtest86+ autoinstaller to install it on an empty USB thumb drive and boot fom it

what autostart apps are running?
run "msconfig" , look at tab startup

Not sure if you saw the post i posted above, so I'll repost it.
