BSOD Installing new BIOS update FFFFF880099005C4

Nitroglycerin · 24 Jul 2014

I just installed new bios drivers, everything is fine but when the computer restarts the only bootable device is my second hard drive that I use for storage only.

I choose this as my SSD (windows installed on) is not shown, I get this error when I start the computer, can't remember what it said exactly but it was some small text like "Can not find bootblabla"

I unplug my secondary hard drive from my motherboard and the computer starts fine from my SSD disk.

After being on the desktop for a few seconds I get this blue screen of death popup, I restart the computer again and plug in my secondary disc and now it runs fine pretty much.

Just want to check if it wasnt anything serious and would appreciate if someone could check the error for me.

here's what your dump file says

Code:

BugCheck 50, {fffff880099005c4, 0, fffff880095d7988, 2}
*** WARNING: Unable to verify timestamp for IOMap64.sys
*** ERROR: Module load completed but symbols could not be loaded for IOMap64.sys
Could not read faulting driver name
Probably caused by : IOMap64.sys ( IOMap64+1988 )

That is the Asus GPU Tweak and GPU Tweak Streaming. I recommend uninstalling it. Then check in C:\Windows\System32\drivers for IOMap64. If it isn't there check in C:\Program Files (x86)\ASUS\GPU Tweak. If you find it, delete it. then Open a elevated command prompt ( click start, type cmd in the search box, right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.
