2 hour restart and NTVDM.exe

I have a windows vista ultimate edition toshiba laptop, and i have two problems i need help fixing. the first one just started like yesterday when i was getting help from chaslang to solve some malware problems, the second is the problem i posted about in the first place that was not resolved by removing the malware.

1. Whenever i right click on a file torrent and click "open containing folder" i get a command prompt that pops up for a few seconds and then a window that pops up and says "NTVDM.exe has stopped working" and this is what it says for more info

2. my computer restarts every 2 hours give or take a few seconds, without fail. it has been doing this for almost 2 months, and i just now have time to try and solve it, however i cant seam to figure anything out, so i am here asking for someone to help me figure out what the problem is. I looked into the event viewer and the only thing i see from the times it restarts is this log:

Event 6008: The previous system shutdown at 12:30:27 AM on 8/5/2008 was unexpected.

ill do whatever it takes to stop these problems, but im really hoping it doesnt turn to reformatting.

 

It's ok, now that I got rid of all the malware on here, instead of continueing with problems, I did a Vista repair/upgrade install so that i have no problems and pretty much a new copy of windows without the reformat. Thanks for the help though.
