Windows 7: BSOD - AMD V120 to AMD N660

BSOD - AMD V120 to AMD N660

Attachment 185080

Thanks for this forum and especially thanks for the hoped support!

I upgraded the processor from AMD V120 to AMD N660. Using a backup I made minutes before the upgrade I restored it using Todo Backup with it's Restore to Dissimilar Hardware feature. All came up good and I saw Windows download drivers for both new processors only. I rebooted and after just maybe 3 minutes of idling from seeing the desktop I got the bsod.

I had more from trying to fix all this but that was the most recent bsod, I hope the dump file is included in the attached.

Remove comodo internet security.

Remove kaspersky a.v.

For system security download,install,use Microsoft Security Essentials with windows firewall.

Run SFC /SCANNOW Command - System File Checker You may need to run it 2-3 times to "fix" everything.

and post back.

Thanks so much for the help!

I uninstalled KAV and Comodo and installed the MSE Package with firewall.

Acer did not provide any disc with this laptop when purchased new so I created a Repair disc, a Rescue disc, and Recovery disc's immediately after realizing so.

I booted with the Repair disc and ran sfc /scannow 10 times in DOS and see 6 components that couldn't be repaired, please see attached. In looking at replacing them manually from my discs, I see I can only find E:\sources\boot.wim\Windows\System32\wbem\mofd.dll and it's version 1.13.

I only have boot.wim in my discs (no install.wim). Palm.browser must be my PDA software which I could uninstall if I need to.

Thanks again for the support.

If sfc cannot "fix" the system.

Then you may need to run Repair Install

Or in your case "Repair disc, a Rescue disc, and Recovery disc's"

I did run sfc using the Rescue disc as well, and still had those same 6 un-repaired.

In reading the warning on the repair-install page, it appears I'm SOL without this installation disc, shy of a format/reinstall.

I knew this lack of a retail OEM Windows 7 installation disc was going to bite me some day. Acer should have provided one!

Would it be possible to run sfc using a borrowed retail OEM Windows 7 installation disc?

Yes, in fact with the System file corruption likely caused by Commode-O your best bet is to start fresh with a perfect reinstall of factory OEM, following the steps here which were assembled based on helping thousands of reinstalls here: Reinstalling Windows 7

Note that you can unlock all versions to reinstall yours using any retail installer's extracted ISO.

Well, I'm thinking perhaps I have an incompatible or faulty processor. Even after deleting the drives and trying to install windows for the first time it crashed. I put my old processor in and all is great again... what a mess!

Could someone perhaps confirm compatibility for me?
Maybe with free access to Acer Support, I can't get them to give me a yeah or nah.

I've an Acer Aspire 5251-1513 with the below motherboard and I'm trying an AMD N660:

Manufacturer Acer
Model JE50_DN (Socket S1G4)
Version V2.14
Chipset Vendor AMD
Chipset Model 785GX
Chipset Revision 00
Southbridge Vendor AMD
Southbridge Model SB850
Southbridge Revision 40
System Temperature 52 C
Brand Acer
Version V2.14

I di find a list of supported CPUs. Unfortunately mine's not listed but maybe it's because it hasn't been tested yet.

I see in there that, like the N660, the supported x920 also supports DDR3-1333 as the fastest memory. Per Acer, I can only use DDR3-1066, which is what I have 8GB of, perhaps that's an issue. I do see list DDR3-1333 as an upgrade for my beast so maybe I could use it if I need to.

Thanks for all the support, it's all good now!

The only thing different is the processor, the one I had initially must have been faulty.

No more BSODs or App crashes and, not relating to the processor, I'm finally getting clean SFC runs after again re-installing Windows.

How to best monitor an AMD N660?
What would say is the better tool to use? I've been using Core Temp 1.0 but it doesn't display the second core in it's GUI or in the logs. Aspire 5251 Windows 7 Home Premium 64 Bit SP1
