BSOD shutdown becoming more frequent error ntoskrnl.exe+7fd00

[blueboy]

Hi guys i really hope someone can help me with this i have been pulling my hair out for a while now and going in circles

this all started back in august ( yes way back ) i was getting the odd crash blue screen i thought it may have been a virus causing it so did all the usual scans but the crashes were still happening one every week or two then lately they started getting more frequent I searched around for a solution and reading on differant forums I thought i found the answer although it ment drastic action i backed up what files i needed to keep and did a factory restore on my laptop to factory settings thinking this would solve it ( wrong ) im not very techy still learning a bit at a time ....now i have managed to get into the dump files and its saying the cause of the crashes was ntoskrnl.exe +7fd00 but reading a little on the forum this may not be the cause i have uploaded the logs if someone could have a look for me and perhaps help in any way to solve this problem be very grateful .

my device is acer aspire 5749 notebook
windows 7 home premium 64 bit SP1
intel core i3-2330m
intel graphics 3000
6gb ddr3 memory
750gb HDD

While i was running the log collecter i had a few more blue screen crashes so im not sure if all the logs completed so i have 2 zip files i will upload both thanks in advance guys

Run MemTest86+ for 8 passes, It must be MemTest86+. http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

Thanks Laith for your quick response and for your help really appreciate it mate i will run the MemTest86+in the morning and get the results back to you tomorrow i have never opened a laptop to see the inside as i am a complete newbie to all this is there a tutorial to removing and replacing the Ram stick and where to find them in my laptop would i need any special tools for this besides a screwdriver lol thanks again for your help.

 

[Laith]

This will work on any laptop.

 

[blueboy]

That was quick cheers bud i will have a good look at it before i start thanks

hi guys im having problems running MemTest86+ I have put it on a 16gb Kingston usb but it will not boot I then tried with a cd disk and burnt the iso version on but this does not boot either am I doing something wrong or missing something I followed the instructions with the ram test ...also had a few more blue screen crashes on reboot .Microsoft updates installed 142 updates this morning that's why its took so long getting back to you sorry

Hi blueboy,

If you have secure boot enabled in the BIOS, please disable it.

 

[blueboy]

Hi axe thanks for replying how do I do this

 

[axe0]

Before Windows loads you can press 2 keys.

• 1 gives the boot options,
• 1 gives access to the BIOS,

The one that gives access to the BIOS is the one you need to press, I believe it is F2 for Acer laptops.

 

[blueboy]

thanks for your help bud ill try now

 

[blueboy]

Hi it's been running for 20 min on 54% of first pass and showing lots of red addresses on the bottom should I just leave it to continue thanks

 

[Laith]

Yeah, that means one of the sticks are failing, replace the RAM immediately, but if you can run with one stick then run with one stick. Also yes stop the test, the RAM is failing.

 

[blueboy]

Thanks guys for your help would you advise that I increase the ram apparently I have the option to increase it to 8gb or would I be best to just replace what I take out would there be less issues if I increase it or would this cause more problems ....really appreciate all your help guys

 

[Laith]

Well, one of the RAM sticks are failing, you can't go with that option, it won't help.

 

[blueboy]

Sorry to be a pain so if I replace the two or whatever is there that should solve the problem then

 

[Laith]

Yeah.

 

[axe0]

I would keep testing until you know for sure if it is a stick or slot, so test each stick in each slot separated from the others.

 

[Laith]

Well yeah, that's true.

Hi guys sorry only just saw your post axe0 I removed the cover from my laptop I take it I should remove one of the memory cards from its slot and rescan the mem again .....but which card should I remove there are two slots with two cards the top one has a 2gb card in it and the one under it has a 4gb card ( is this correct as I thought they had to be equal as in 2 x 1gb or 2 x 2gb ) as far as I know iv had the laptop from new it's never been opened or repaired by any one also the 2 cards are different makes the 4gb is Kingston and the 2gb is a hynix make is this right I wii put a picture of them if you guys could advise me on what I need to do now ....do I carry on scanning with 1 or both ...and do I have it in the top or bottom slot ....or should i just replace the two cards with new ones but what size each one i think the maximum upgrade is 8gb for the acer aspire 5749 .....I really am at a loss here thanks for your help guys .

I tried to upload the pictures of the memory cards but was getting server error I will try in the morning
