Minidump not working

Hello community,
I have the occasional BSOD. I have minidumps enabled in the system control panel, small dump, no auto restart etc. Thing is, when the 'puter BSODs, there's no log. I get 'BAD_POOL_HEADER" and a couple of others. Seems random, can go for days without any, then one day many. Any suggestions?

Thanks in advance

I apologize for my lack of knowledge. What is the page file called in Win7? As I recall, it used to be called pagefile.sys and was in the root of C:. I can't find anything that looks like it. The size setting is 8 gig in the system controls but I don't know how big it actually is.

I've run that a couple of times (last time was probably in late February) against my current hardware config, 7 passes each time, no problems detected. I could try again I suppose. I had 'turned off' dumps a while back, then turned it back on because of the random BSODs. I'll run Memtest overnight and see if anything shakes out.
Thanks for the suggestions pbcopter.

Memtest says all is well. I'm going to wipe my C: Drive and reinstall Win7. I had upgraded from Vista Ultimate and may have screwed myself during that process or when trying to find modern drivers for various things. I've had problems with some windows updates and SP1 (won't work no matter what). Clean slate time.

Thanks. I'll post an update one way or the other.

I did a clean reinstall of Win7 on a clean disc. No issues so far, when I did the upgrade last time I had tons of problems. All windows updates worked this time. I have high hopes. I will report back if any, or no problems.

So far, so good. The machine ran all day without a problem, and I installed Office and Steam and a couple of other things. Not so much as a hiccup and I think it boots faster. I should have done a clean install in the first place.
