Stop error: 0x0000008E after opening program, Stop error occurs after I open particular program application Options

[BCEureka]

Hello and I hope someone can help.

I looked through quite a few posts but I could not find an exact fit with my problem but I have tried many of the suggestions mentioned in postings that were close to my problem. First of all I am on a Dell Inspiron 600m using MS Windows XP Home Edition 2002 Service Pack 3.
My problem occurs when I try opening up one particular program application (QSR NVivo). This is not a new software package and I never had a problem with it before. However the problem began right after I updated my Yahoo tool bar, ran its antispyware and removed what it found. I did check to see if any of what it found seemed related to any certain applications but nothing stood out as anything more than adware and one trojan. So after removing those issues I tried to open my NVivo software which resulted in the stop error: 0x0000008E (0x00000005, 0xF4c6c21D, 0xF17cc7Ec, 0x00000000). At the top of the screen but not in the area where it would identify any drivers it said "Try changing video adapters" (just thought that might be worth including) Anyways, this happens each time now. I did remove the yahoo updates in case that was an issue.

Solutions I tried:
- Tried the driver reset tool but it showed nothing wrong.
- Tried a system restore but for some reason there were no restore points available.
- Windows Memory Diagnostic. I downloaded the necessary files onto a bootable CD through my NERO software but the diagnostic never ran and only opened up a DOS prompt. After many tries I abandoned this.
- Ran Malwarebytes Anti-Malware. Found a trojan or two and some spyware. Still got stop error.
- Downloaded and ran Avast virus software and it found another Winsystem32 trojan-gen (something close to that)
I really went through everything that was suggested in posting http://www.bleepingcomputer.com/forums/topic133988.html

Over the past few weeks program such as MS explorer have had problems freezing up and now with this new problem which some suggested may be a RAM problem, I was thinking that may be the issue rather than a virus. But since the memory diagnostic not functioning properly I don't know if there are any failures.

I hope this helps and I have included enough information to illustrate the problem up until now.

Thanks in advance for your help.
