[Resolved] Boot freezing at splash screen

sylar · June 27, 2014

Hi, a bit of background info:

Currently i had this problem where about 50% of the time when i turn my computer on, it would freeze at the windows splash screen (or bsod). Resetting my PC after the freeze will usually reboot fine without freezing a second time in a row.

Tests i've done:
memtest86+ - Passed 10 times with 0 errors
chkdsk - Tested hdd, no errors
Vivard - Tested ssd and hdd, no errors
Gpu stress test for a couple of hrs with no errors

Now after that i've also disconnected my optical harddrive and ran it for about a week. Computer was booting completely fine, no freezes.

Then i connected the power to the optical drive but not the sata connector for about another week - No freezes at all. (to eliminate possible PSU problem)

So now im wondering if it's my optical drive that's causing the issue or my motherboard. I remembered I took some photos of bsod message a while back (since it bsod before loading windows, dump could not be generated)

and these were the ones that showed up (either one or the other)

I noticed in my device manager, optical drive had "iaStorF.sys" and there was something listed as "iaStorA.sys" in under the chipset

I know the bsod error pictures won't be enough to give a full analysis but does it give some idea what the problem may be?

Specs:
4760K stock
GA Z87X UD4H
2x4gb G.Skill ripjaws DDR3 1600
550W Cooler master eXtreme power
M4 Crucial 60gb ssd
2TB WD hdd
Windows 7 x64 bit

(Windows is on SSD)

Thanks for reading!
