Since I got WinXP Pro about 4 years ago I have never had a BSOD.
I used to get them every once in awhile with Win98SE and I found out that they were mostly caused by certain hardware configurations on older PC's.
The worst OS's I have had problems with were Win95 and WinME, BSOD all the time.

Hi, cholla, just been through this sh*t , you are going to   at this , it started about about a month back , never had one b4, it hinted at a ram problem, so I went through all the procedures, reseated the memory, no change, so I did all the mem. tests , no fault,
looked at temperatures , all within limits, tried a automatic restore point , 3 month's back , lost a lot of info. in the process  , no change, posted on testmy.net, this again pointed to memory problems , nah, did not believe that ( 1 GB of Crucial finest ) did a clean install , and within 5 Min's. BSOD, :angnry5:opened the  box , checked all connections, reseated the CPU , after running around finding some heatsink  paste,
no change   , I was stumped , swapped the memory , no change ,
played with page file size , on 2nd H/D, then got error Page file ,
My page file is on my 2nd hard drive, which is mounted in a caddy, the slide lock was in the mid position , moved it to lock , problem gone 
P.S. the G/F. had given the puter a polish , the ex G/F maybe 

I'm still going to reply to Mastertech in the topic I moved.I did some of the tests & my computer did good.Still I haven't got as much as I want to done.
Roco ;I get a problem simular to yours sometimes.I get a your case has been tampered with warning from the IBM Bios before Windows opens .When I know it hasn't .So it's a lock problem of some kind I think.

If you do get a BSOD, just write down the file that caused it, and Google it + BSOD and you should find someone who had the same problem.  Generally it's a driver issue, and if not, the most likely hardware is RAM.

I am running windows xp pro with sp2 some software is now requiring it..   But anyways.. the only blue screen is one on shutdown only when I forget to terminate my vpn.. It fails the wifi card and it blue screens.. I dont know why.. but it just does.. I guess it is one of those extra features included in windows XP

Never fools, Linux runs 100% (as does MAC OS X).

But those damn WIN2K workstations at work....you're guaranteed to see a BSOD about once every month or two on your machine.  I loathe Winblows.  Right now, i've only got XP installed for a very few apps (mostly games).  I spend most of my time booted into Linux.
