Blue screen for Christmas

Not sure if this is a software glitch, but I got a "blue screen" a few weeks ago, referencing additions to my computer, and the computer shut down due to a "serious error." It rebooted itself.
Only addition has been a printer, and that was added after problem came up.
Just now it did this again. I did manage to copy some of what message I saw.

"BCCode : 10000050 BCP1 : D8000020 BCP2 : 00000000 BCP3 : BF80A61B
BCP4 : 00000000 OSVer : 5_1_2600 SP : 3_0 Product : 256_"

Any idea as to what is going on? Computer having a nervous breakdown?
I've got enough problems with OEx and trying to save email when I transition to Win7 from XP
Sarge:cry

 

If what I found - after removing quote marks from error msg - holds, I have registry problems
Came across program that checks for those. It found 9 jillion (cubed) which of course they can fix for a fee.
Is this one of those online fixes for a fee, or take it to a tech fix, also for a fee?

 

Blue screen crashes can be investigated as they leave a file behind that, with some difficulty, can usually be used to help trace what caused it. Most frequently the cause is a driver got updated. But before we try that route, have you tried a system restore to the previous day?

 

Although I don't expect an answer Christmas eve, am posting this Christmas eve.
System went down again, few minutes ago.
In addition to info supplied in first part of this post, I was able to get the following also:

C:\DOCUME~1\ROSS\LOCALS~1\Temp\WER0b36.dir00\Mini122414-02.dmp
C:\DOCUME~1\ROSS\LOCALS~1\Temp\WER0b36.dir00\sysdata.xm

The info from the earlier event was:

"BCCode : 10000050 BCP1 : D8000020 BCP2 : 00000000 BCP3 : BF80A61B
BCP4 : 00000000 OSVer : 5_1_2600 SP : 3_0 Product : 256_"

 

Looks to be a process.
I'll need to set a little time aside to do that. Want to insure I don't muck it up half way through
Did some research on my own, after figuring out I had to remove the quote marks from the error listings to find articles.
That brought up a heat problem as a likely source of the problem(s), i.e. fan not working or not properly, a defective capacitor(?) or some such.
Posting stated HP, among some others, had a history of heat related failings.
I would bet the proverbial dollar to the donut hole mine will be the most expensive.
So, for now, back to the family holiday. Computer will just have to wait
Thanks for the expedited reply, was not expecting one for a bit.
And to all who hang out here, especially the MG's who have put up with my chronic problems and grumbling over the seeming eons, many thanks. Merry Christmas, or Happy Holidays, and a hope for a prosperous new year to you all.
