Windows stuck on classpnp.sys after RAM upgrade

[marksy1988]

Hello all, I am new to this forum.

I have bought two new sticks of Crucial 4GB DDR3 1600 UDIMM for my Gigabyte GA-H55M-D2H motherboard. After the switch the windows gets stuck on window loading screen (before the logo even starts to assemble) and when booting in safe mode it gets stuck on classpnp.sys.

I have tried using the sticks in another rig and they work fine, I have also tried different sticks (kingston hyperx) in the rig and the pc had the same windows loading problem.

The bios version of the motherboard is F3. And the sticks should be supported. I was searching for XMP search in mobo but didn't find it. The RAM sticks are 1600 but mobo recognizes them as 1333 mhz.

I can't even load windows setup from a DVD using these sticks.

The rig works fine with the old 2gb 1333 stick.

Any suggestions? I am a bit frustrated, been trying to solve this for about 6 hours now.

Go into BIOS and load the defaults. Make sure RAM settings are auto for now. Try and report back please. XMP may be in the same setting where you select Auto.

Hi, thanks for your help.

Defaults loaded, RAM settings on AUTO, same issue. Memory frequency still recognized as 1333 mhz.

Tried 1 stick at a time? Only 2 slots on that motherboard, right?

 

[marksy1988]

Yes I tried all the possible configurations. Both sticks as single on different slots, I tried 2gb (the working one) + each of the new sticks, all ended in the same result. Yes only 2 slots are on the Mobo.

Hm, I just made ntbtlog.

loaded driver \SystemRoot\System32\Drivers\CLASSPNP.SYS
DId not load driver @nettun.info, %isatap.displayname&Microsoft ISATAP adapter

So it seems the problem isn't CLASSPNP.SYS but the driver after that?

 

[GokAy]

isatap is network related, is that while loading normal or Safe Mode?

 

[marksy1988]

Normal loading: stuck on starting windows
Safe mode: stuck on CLASSPNP.SYS
Enble boot looging:

loaded driver \SystemRoot\System32\Drivers\CLASSPNP.SYS
DId not load driver @nettun.info, %isatap.displayname&Microsoft ISATAP adapter

I check the event viewer and got

Have you tried booting to the Advanced Boot Options menu (where you can choose Safe Mode) and choosing Last know configuration that worked?

 

[marksy1988]

Yes, to no success unfortunately.

Any other ideas?
