Bug check title is MEMORY_MANAGEMENT  Code is 0x0000001A which I recall is memory

So as others have said, Memory is the likely cause.

a stop 0x1a is MEMORY_MANAGEMENT
has anything changed on your system such as adding new hardware (especially memory or video card)?

can you post that minidump file?
Pradeep DubeyConnect With a Mentor ConsultantCommented:
I'm thinking of a RAM issue here.
please test your RAM once and upload minidump file here for detail analysis.
Minidump location is already given in the event zip it and upload here.

You should post the dump file here to see if some one can decipher a problem from that.

1. Did your system recover and it is running?  Or does it remain non-starting?

2. If running, can you restore to a prior point?  Action Center, Recovery, Open System Restore. You may have a driver that needs updating.

3. Have you / can you go to the manufacturer's support site and update all drivers? Pay attention to BIOS, Chipset and Video first, then network drivers. Manufacturers are releasing driver updates for Windows 7 and Windows 8.

4. Have you done all Windows 7 optional updates?  Some .NET Framework updates are hiding here.

going back to my original question...has anything changed on the system - especially memory or video card?

i noticed intel drivers in the dump; are you using integrated video with the latest available chipset drivers?

run a memory check
nobusConnect With a Mentor Commented:
you can :
remove and reseat the Ram sticks, after a proper inspection of the connectors and slots
check with each stick separately - to see which one is bad

you can use the ram diagnostic from the UBCD :
Hardware diagnostic CD    UBCD
 i suggest the UBCD  to run some diags first - to be sure about the basics
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)                        ultimate boot cd             download page

could you please specify what the root cause was and what you did to resolve it?
questions were asked that weren't answered and you marked all comments as a solution

was it memory?  was it another piece of hardware?
jegajothyretiredAuthor Commented:
In response to seth2740, I think it was a combination of a virus and memory.  I had the pc first cleaned up by McAfee and then ran my Lenovo utilities, and since then my pc has been behaving good. thank u.
