Absolutely Stumped Win7 Boot Crash On Logo Startup

Hey guys n girls, I've got a few problems with my PC I've tried to explain the most recent activity that I've down before my problems,

I've built my own rig for about 10months now no problems until now. (see specs below), I installed a driver genius the other day and it said my usb drivers where "prehistoric" so I took their advice and updated it all. my two main usb3 ports stopped working, I uninstalled the driver genius & re installed the correct drivers and still same problem. After fluffing around I re-installed Win7 clean and went to the ASUS website downloaded the correct drives proceeded with installing them all. Some forums said to update my bios for usb3 trouble i did so and updated to latest. System didnt want to reboot. So again reinstalled win7 and now I was running fine..still usb 3 trouble. (only on the 2 usb3 ports above my ps2 ports) Anyway, my system now has a mind of its own when I boot it up it will either boot without trouble and run perfectly. But as soon as I shut it down and go to reboot it will ask me to repair or startup normally and when i select either one of them the logo screen will try and come up and immediately crash and reboot. Unless I take the power plug out or bios battery and reboot this way my PC will not turn on.
I've run memtest86 with 100% passes and Im stumped. I have a feeling its my bios. *also i did a clean install today and all my usb devices work and I noticed they are working before I install my drivers from ASUS website. In device manager I right click on USB Root Hub >advance they are set to HIGH not super.* Im afraid to install the intel/asmedia usb3 drivers.

Another side note, when I try to install ASUS Mobo drivers some of the exe's tell me my system isn't compatible with what Im trying to install yet I'm downloading the latest drivers under my mobo model number.
Bottom line I want my PC to boot 100% of the time all the time as I use my PC for work. Im up to try ANYTHING.

Thanks to all that will help,
SPECS;
Windows 7 Ultimate (x64) Service Pack 1 (build 7601)

I can attach a full detailed report on what my PC has in it and running if need be.

 

Hi and welcome to Computer Help Forums.
My guess is some software you have installed is causing the problem.
Why, because you have to set the Bios back to default every time before it will boot.
Try booting in Safe Mode, what happens?

 

I think you're correct. Because thinking back the only time it crashed was after I was installing drivers. How would I narrow this down to the driver I installed? Even in safe mode.

Thank you

 

In Safe Mode only essentials load.
Please see what happens when booting in Safe mode.
We ask you to do this for a reason.
Thanks.

 

Safe mode is also doing the same thing, I notice sometimes my computer doesn't even go past post screen. When this happens my boot led on my motherboard stays on.

 

Hi, because you have changed just about everything, including the BIOS, it is now getting confusing, you just may have installed the wrong BIOS update for your particular model being the first place to look.

I think perhaps now the best thing is to find the original motherboard model and even serial number and then E mail the makers asking for the correct BIOS update for that board.
If we can be sure that is correct, then things can move on in a logical way rather than trying this, and then that which just confuses the issue even further.

Hi Nev,
The BIOS I have installed is from Asus under the correct model and make on their website I assure you that. But I will do this according to your instructions for I'm desperate.

Thank you

 

Further to Nev's good advice I would definately run a CHKDSK repair to eliminate that possibility.
Could possibly be that Windows is trying to read a bad segment on the Hard Drive on boot.
The post screen is when Windows is looking for the Hard Drive.

Note. If this OS is on a SSD, I personally have had 3 SSD's fail while still under warranty.

 

Just to back up DSTM's excellent idea, I would recommend you do that CHKDSK first before anything else, if not sure how, please ask.
