BSOD happened every 1 hour and Error "pfn_list_corrupt "

Hi all,
My laptop compaq suddenly got BSOD error yesterday and caused me a lot of headache. I googled and did all of solutions like : Safe mode, last good condition ,check disk,scan driver,...restore computer many time but BSOD still happens ...except openning my laptop to see RAM ...
using Win 7 64 bit with AMD chip ...I ran the SF Dianostic tool and a box poped up noticed about :" can not handle the file EventApp.txt ,if you click continue button SF will ignore this error and go on scanning" and I quickly click to continue the scanning .
The BSOD caution is " page fault in nonpage area "
below is my SF tool log zipped
thank you all for your reading and helping.

Hi Koolkat
thank you for your advices.
so far,I tried many solutions.I have not tested memtest yet.I disassembled my laptop part by part.I replaced my hard disk by a tested mobile hard disk(installed another win 7 Ultimated) and it was Ok.. no BSOD.I remove and re-installed 02 of RAM sticks and It was OK ..no BSOD .then I re-assembled everything now it so terrible .it got BSOD right after I logged in Windows.I started run verify drivers and It got BSOD so quickly that I could not read the notice which driver caused BSOD ,then It suggested me to repair error files.After restart, surprisedly ..It ran Ok and no BSOD.I have still run verify drivers and 3 hours later BSOD happened again. I repaired all files again and so far It was no BSOD (8 hours).but the latest crash event notice appeared still was Bc code 1e.Pls see my newest SF log zipped attached.
Thank you.BTW, I realize that my laptop compaq presario has not updated BIOS for 1 year.how can I update its BIOS now ?

Another BSOD happened today ... i put the laptop sleep and when i waked it up ..BSOD immediately and the error code now changed : bsod crash stack based buffer overflow and code f7

Pls see my latest log attached.thank you
