aspire 6920 problems fixed??

i have had a lot of problems with bsod,freeze ups, random shutdown and startups, finally wont boot up, just the the hd light flickers a couple of times and the bluetooth light comes on and just a blank screen.

I took the back cover off, reseated the memory and hard drive then powered up...it booted into windows. I then put the cover back on, tried rebooting...no boot up. Took cover off again, powered on, it booted up

Left cover off shut down and rebooted several times....it worked

Maybe it has something to do with the way the screws are tightened down...i dont know, but my laptop is now booting up into windows...

Now, i guess i will re install windows becuase i have some corrupted programs from the shutdowns and freeze ups...hope this helps anyone with their problems, if so, let me know...

Right now, i havent had any problems and if this helps others with same problem, then i am almost certain this is the cause and i can be sure i found the cause of my problems

 

So, your laptop is now naked?
OMG!
That might look awful.
I prefer a better looking laptop.
Just now, I tried to clean the bottom of my laptop.
Mistakenly, I dug a hole on the anti-dust layer. T.T
But the laptop still can boot-up(LOL of course it can).
