Okay hello I'm dan. new to these forums. anyways im a 'simple' computer tech, i can change memory replace hardware remove viruses etc. I'm having a problem I cannot fix. I get the blue screen BAD POOL CALLER, and it automatically restarts RANDOMLY. i jus recently learned that i can disable this autorestart to get a better grasp of exactly what code it displays before it quickly disappears.. Now.. internet points to a bad memory stick. Dell latitude d630. Now the laptop i happen to have has a normal so-dimm memory slot on the bottom, and a seperate one under the keyabord... I would like to avoid taking the whole keyboard apart to try to change the 1 memory stick. However- i ran memtestx86 through 1 full pass and it detected NO errors. Now, sometimes when I'm playing music or using resources it literally FREEZES.. like if my musics playing itll freeze on the exact note and go ~pshhhhhhhhhhhhhhhhhhh.~ until i shut it off manually.. this is a vista i recently upgraded to 7 ultimate, and i've never had this problem before. I located the .dmp (minidump?) file... its about 150 megs... im not sure how to view it... or if i should upload it or if you guys can help me out. ALSO, this may be unrelated, but my speakers sound a little crappy when i turn it up.. but im not too concerned about this. I upgraded all the drivers and it still happens. I try to do windows updates and it freezes on "net framework 4 security update" or something like that.. i had to manually install net framework (offline installation) and now i cannot update it. I've switched from xp to 7, done this a million times. I jus bought this laptop off of ebay and I would like to get it going.. 2 gig ram 2.0 ghz dual core duo I'm not sure how to handle it from here if someone can guide me please i would greatly appreciate it.... and btw.. doesn't it suck it has 2 seperate memory slots . I desperately do not want to remove the 1 under the keyboard.. So... when i get out of work ill disable that restart on crash setting and write down the exact error: "00000cx" etc . however... im not sure what to do with the .dmp file if that will even help. ALSO. sometimes I startup the computer and it acts funky- the start bar wont work or something n then i restart and it works fine... please someone help... oh btw... i LOADED up the memory opened 100 firefoxs and stuff and it was fine- then i opened another program and cant remeber what it was, and it froze... Damn. thanks a lot guys!
