I have run into a bit of a snag trying to revive my computer that keeps getting a BSOD ~20 seconds after windows startup.

I am running XP SP3

"STOP: 0X0000008E 0Xc0000005 0xA12AFB75 0x9F0F47E8 0x00000000"

Here is what happened:

I was browsing the internet lastnight when my start bar and start menu changed from XP default to the 'classic windows' style. I restarted my computer and a few seconds after windows put me at my desktop I got the BSOD as described above. I booted up in Safemode then I attempted to open "Malwarebytes' Anti-Malware" however it would not open. I then opened 'SUPERAntiSpyware' using its alternate start (normal start would not open either) and scanned my computer. It came up with:

(with 57 entrys for the rootkit)

I removed them all (+ some tracking cookies) and then restarted. booting back into safemode
and was then able to open Malwarebytes Anti-Malware which came up with the following:

1 infected registry key:

2 infected registry data items:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogo\userinit (Trojan.Agent) Data: C:\windows\system32\
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogo\userinit (Trojan.Agent) Data: system32\

1 infected file:
C:\windows\system32 (Trojan.Agent)

all of which were 'Quarantined and deleted successfully'

I then rebooted and ran windows and got the same BSOD.

after some reading online I was told to use the minidump feature of XP to find what was left (I was told most likely a rootkit that I can't find). I was however unable to open the .dmp files. I searched and found I had to download a viewer (Horrible idea Microsoft) which I am unable to do due to the computer BSODing when im not in safe mode.

I am not sure what to do from here, can anybody help?

I'm not sure but I think you can read the minidump files in safemode.
Maybe it's just me but I believe you infection and BSOD might just be coincidence. The error code is pretty generic and could mean a number of things. Most often it has to do with memory. Try re-seating the memory or try one stick at a time.
If you can access the dumpfile in safemode w/networking, post the log in the XP forum

The trouble with the minidump files is that I don't seem to have anything to open them with.
When I boot in XP with networking I can't access the internet.

I have not opened my computer up since I built it, however I had a memory issue when I built it with one stick arriving DOA. I have been using just one stick. I will try re-seating it when my Scan finishes and will post results here asap.

I re-seated my RAM a few times with no change. I am running memtest now.

Memtest ran without any errors.

I posted my minidump files in the XP forum here
