BC Code 1a,50 BSOD

[taarno]

Hi guys

First of all this is my first post so hello to everyone.
I am hoping someone can help me out here. I have read many of the posts with great interest, regarding BSOD and crash dump files. I am also having a problem with this. I have read a lot are having problems with Nvidia cards, I also am using the 8800 GT although a lot point out they have problems when gaming I am not a gamer. The only game I play is solitaire and interestingly I often get a crash during this hardly heavy gaming.

I had a crash this morning and I was only downloading and browsing the internet at the same time.
I seem to get different BC Codes examples 1a, 50 ,3b
I have posted the dump files hoping someone could help me out.

Blue Screen of Death (BSOD) Posting Instructions

Probable reason

I obtain the same Blue screen and I am sure, that the reason is insufficient power source. I have connected 20 ATX pin into 24-pin motherboard connector (plus 4 pin additional CPU connector). I am not gamer, but I use system power most-consuming application.
I haven't idea, what other reason this specific cause induce.
