Having an issue with my mums 6 month old system. Seems to randomly lock up or just the screen will turn black and then it'll reboot itself. Checking the event view its showing bunch of event id 18 and 20 errors.

Have looked on BlueScreenView and its showing ntoskrnl.exe issues on all of the dumps.

I've tried running prime and memtest but it just sits there happily processing away with no errors

CHKDSK /f comes back clear

Anyone got any ideas??

Motherboard: Gigabyte F2A88X-D3H
CPU: AMD A6-6400K
everything is running at stock
 
just crashed again... have checked WhoCrashed and its showing the following

This was probably caused by the following module: ntoskrnl.exe (nt+0x4AF18C)

Have checked HW Monitor to see what the temps are showing as... seems to be sitting around 45C (the max is showing as 75C)

When it crashed it was at 68C... too hot???

She was playing some online flash games at the time... surely that can't put that much load on can it??

Is it just getting too hot and then rebooting itself? (sometimes it just locks up and doesnt reboot itself). Its just the stock cooler that came with the cpu

Strange thing is tho I've run a Prime95 test for several hours, but it just doesnt crash... the temp gets up to 80C but it doesnt crash out at all??

just rebooted as I was posting this... temp was current at 47C that time

for the A6-6400K its says max temp is 70C... but I've had it up to 80C with prime95 and it was totally stable
 
I ran SFC/ SCANNOW the other day... but dont understand/know where to look at what its telling me

OS is windows 7
 
yeap have checked aml and virus all clear

will give drive booster a go and make sure everything is all up to date
 
updated the drivers... just some audio and usbs ones that were old.

am using kaspersky and malwarebytes anti-malware

See if that has fixed it? or are you still getting the problems?

something else must have updated as well as now when running prime95 100% CPU and 95% Ram usage is only generating 50C rather than 80C :D

too early to tell if this has fixed the reboot issue tho, that would happen too randomly to be able to reproduce it. I'll give the system a good work over for the next couple of days and see how it goes. I'll try a start up repair if/when I get a crash again.

thanks for your help
 
nope, still having issue... system just froze :(

whats weird is prior to it freezing I had just moved some desktop icons around. 5 minutes later it froze. I rebooted and the icons where all back where they orignally were???

going to try a startup repair next I think
 
have tried doing a startup repair, but still having the same issues

is it worth trying a fresh install?? or is this issue hardware??

WhoCrashed makes it look like its a hardware thing

but I have no idea??
 
yes it just started out of the blue, nothing had been changed at all as my mum just uses it as an internet machine and to download photos from her camera... hardly intensive stuff

I've flashed the bios to the latest version and I've swapped the ram from one of my system and it seems to be stable at the minute (but because of the random nature of the restarts I cant be 100% sure its sorted)

will try swapping the ram back to see if that has any effect, also going to get a new cooler rather then the stock one to see if I can get the temps down as they still seem way too high
