Windows 7 64 bit Freezes and cannot boot new programs (DCOM?)

I did already run 8 passes on memtest

>> memtestx86 has run 8 passes with no issues.

Then again, this was whilst windows was running (I'm assuming 850% coverage from 4 seperate instances of the program whilst I was at work is equivalent to 8 passes. Or is that wrong?)

Also of note; the error occured last night; but if you shut down you can avoid it. Its just if you start to run a program.

I'll admit though; RAM was my first thought when it first hit me.

Anyway, ran Memtest again off my USB key overnight regardless; still no problems; did 9 passes. Also ran CHKDSK with the fix flag, no problems.

No DCOM 5 errors yesterday. I removed the 'device AMDA00 Interface' from the Device Manager; and there is now no User Mode Driver Crash when starting so startup is quicker. I also went to Online Armour and gave wmprvse full permissions just in the vague off-chance its something dumb like that (they were all question marks before though, no blocks, so I don't anticipate that to be a problem).

Google has been strangely slow a couple of times for some reason in the last few days. But no other websites have, so I'm thinking that's an isolated issue.

I'm starting to wonder if this is the culprit:
The driver \Driver\WUDFRd failed to load for the device ACPI\PNP0A0A\2&daba3ff&3.

Since it also shows up during boot basically every time. That said; I checked this thread: The driver \Driver\WUDFRd failed to load for the device... error and my Windows Driver Foundation already starts automatically; so I dunno. I noticed the ASUS website has some kind of ACPI driver (another article somewhere pointed it out, but for some reason I cannot download it (it just halts at 20% every time; very strange as all my other downloads are fine today).

Have the BSOD issues stopped?
If not the dump files are required.
As for the WUDFRd driver you should read this.

Event ID 219 is logged after you install Windows 7 or Windows Server 2008 R2

Well as noted before, there was never any BSOD, per se. It's an unrecoverable freeze so it doesn't generate a dump; I just have to reset it. And yes, it did occur a couple days ago. Not yesterday. I'll keep updating of course. If it seems its gone all stable on me I'll resolve the topic, don't worry; but at the moment I'm still not sure.

Well, it now just happened thrice in succession. It also seems that the above problem with the ASUS website is not isolated to just there. Now, any direct downloads above a certain size (about 2mb or so) just halt at X% and never go anywhere (sourceforge and fosshub also had similar occurances). Booting utorrent to try P2P downloads also seems to cause a freeze (fairly sure booting it in order to try a P2P driver download was what caused the second failure in the above). Google occasionally has moments of terrible slowness before responding.

There are no DCOM errors listed in Events anymore since the 1st May; so something I did must have stopped them; but apparently they were never at fault, but were a symptom given the fact it is still occurring?

Well in any case, my internet appears cocked. I can access webpages, and type right now, but things are definately not right. I used a Ethernet checking tool from Netgear and nothing showed up in that error wise.

Out of random interest; I also tried changing the IDE plug of the HDD to see if that was at fault, but have still gotten issues.

I also tried a Spybot scan on the off-chance its malware; but no results.

Enable Driver Verifier to monitor the drivers.
Driver Verifier -Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point Manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.

Driver Verifier has been running for some time as noted in the first post:

>> Have run DriverVerifier using this post Driver Verifier - Enable and Disable for some time with no problems or BSODs.

Actually, you just reminded me I should finally turn it off; no BSODs have been caused by it at any point, and it must have been running for a week now. All non-microsoft drivers were selected as per the posts instructions.

Honestly I have tried a huge amount of diagnosis and still feel rather stumped with advice from here and all over the web before I even tried this post. The only other vaguely threatening sounding events are:

"The driver detected a controller error on \Device\Harddisk1\DR1" happened before the last freeze, but only shows up occassionally. I believe this is my external 1TB drive. However, I tried using the computer with this drive detached for about a week (nothing essential is on it, its a store for photos and videos), and freezes still proceeded.

"Audit events have been dropped by the transport. 0" Tends to occur after a reset, but again only 1 in 3 times or so.

I'll generate a fresh DM Log dump and attach it again here when its done.

Ah yes, sorry about that I forgot you had Driver Verifier already running.
Yes disable it as it isn't necessary then.
