[A2ZPearl]

hi to all

i got Dell inspiron 1525 2.1ghz, 1gb ram, laptop with vista home basic 2 weeks back. On the first day i got blue screen error of dumping physical memory when again i got it i noticed the error peauth.sys, bad_pool_caller etc etc. im frequently updated the widows but was not able to completely download SP1. After 1 week of 4 attempts i finally downloaded SP1 last night. still im getting Physical dumping memory and blue screen ..
i've run Memtest for 3-4 hours but no error was detected.

Please can anyone help me out where is the problem. and why i'm getting blue screen error, this is new laptop. I don't want to replace it if it not hardware problem. is there something serious?

im attaching zip file for minidump, i dont have bit idea of it. as i came to know that this might help in finding the problem.

peauth.sys: Protected Environment Authentication and Authorization Export Driver

mfehidk.sys: old driver of McAfee (resolved according to their support)
Or Daemon Tools

Daemon Tools <-- Please uninstall and test again
or
Uninstall McAfee, and re-install the latest version (or just get another AntiVirus software)

First of all thank you sir for replying.. much appreciate it..

what are Daemon tool? and they are use for what ? how to uninstall them?

 

[kimsland]

Check Add/Remove programs in your control panel

For Daemon tools or Alcohol (these programs are for creating virtual drives, which run from ram, ie memory!)

 

[A2ZPearl]

i checked in programs no Daemon Tools or Alcohol is there . So it could be MACFEE , what you suggest shall i uninstall it.?

 

[kimsland]

I would!

Although McAfee support stated their updated drivers do not have this fault anymore. But I'd still un-install and then test again
