Z77 Extreme4 Motherboard error 4F on startup. Only happens sometimes.

Hello,

I recently built a new rig which has been working fine for about a year until recently when I reset my computer only to find it would not boot up again.

I have a Z77 Extreme motherboard and the dr.debug says the boot process stops at 4F. I've read around and found similar issues that have been answered, but the weird thing with me is that with a few tries of resetting the computer eventually just gets past 4F and boots normally. So the error is happening most of the time, but not all of the time.

Edit: Also I should note that the computer does not power down after reaching the 4F error. The dr.debug numbers simply start over again from the begining and end at 4F, over and over again until I shut down by holding the power button down.

I've read that this error could be commonly caused by a bad CPU, Power Supply, RAM, or a corrupted BIOS. I'm sure it's not the RAM since I tested all RAM sticks, or the BIOS since it is now powered on, but I don't have a spare CPU or Power Supply to test. I have also tried clearing the CMOS

Does anyone have an ideas as to what could sometimes cause this error, and sometimes not? Here are my components.

SDD: Seagate 600 Series ST240HM000 2.5" 240GB SATA III MLC Internal Solid State Drive (SSD)

CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Desktop Processor Intel HD Graphics 4000 BX80637I53570K

Motherboard: ASRock Z77 Extreme4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

RAM: G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL10D-

GPU: SAPPHIRE 11196-19-CPO Radeon HD 7950 3GB 384-bit GDDR5 PCI Express 3.0 x16 CrossFireX Support Plug-in Card Video Card

Power: COOLER MASTER Real Power Pro RS-650-ACAA-A1 650W ATX Form Factor 12V V2.3 / SSI Standard EPS 12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply

UPDATE: After clearing out my storage HDD and running scans on my SSD with the OS I found no errors or any driver updates that happened recently, but the problem is still happening. I shut the computer down and now it's have the same problem of getting stuck at 4F on startup.

Thank you!

do you have only one ssd like a storage?
do you have enough space left on your ssd?
did you recently upgrade a hardware driver? gpu driver or other

I have a SSD that holds my OS (Windows 8) and a 500GB HDD that I use as storage. My SSD only has the OS and a few other programs installed. It's sitting with 122GB free of 223GB. My HDD on the other hand is nearly full sitting at only 2GB free. Do you think that could be the issue?

I don't believe I upgraded any drivers or anything. Everything's been working perfectly for a while now so I haven't needed to upgrade anything.

''My HDD on the other hand is nearly full sitting at only 2GB free. Do you think that could be the issue?''
yes i think

but just check in case if it have upgrade to do like the latest bios for your mobo and/or the gpu driver etc...
we never know , and sometime doing a good cleanup about driver can fix a lot of lags or errors.
its important to completely remove the driver i mean sweeping in deep , and install the new one after

Ok I'll clean out my HDD and check my drivers. I didn't update them myself but it is possible that something updated automatically.

Sadly this doesn't appear to have worked. I shut down today after running some scans and cleaning out my HDD as well as my SSD and got the same problem. The computer gets stuck starting up at 4F and repeats the process over and over until I forcibly shut down.
