Just want to share a fix that worked for once: I run an i7-950/EVGA X58 Mobo with Win7 64 Ultimate. Been cruising fine for over a year, then one day the BSOD syndrome started after logging in. Boot-up and login was fine, then the Desktop would settle and then within 60 seconds, WHAMMO, BSOD for a BAD_POOL_HEADER. Google searches kept pointing to registry cleaners, and since I have Uniblue's RegistryBooster, I gave it a whirl (hadn't run it in a while). Sure enough, problem fixed, and that was over three months ago. So, worth trying if you get that error.
BTW, search for discount codes, you should be able to get this utility for $19.95. No, I don't work for them, just want to share something that WORKED with y'all.
