Aspire 5755G blue screen on start up

I have managed to reinstall windows from the Acer recovery disc, but the blue screens continue - and not just at startup anymore but during operation of the pc.  Actually, the situation is much worse than it was before.  Sometimes when I try to boot up the computer it says there is no bootable drive installed.  I had to change the boot order in Settings (F2) in order for the machine to read the cd to boot up using windows repair disc or acer recovery disc.  I tried many times to reinstall windows to factory default but all the options were "greyed out" and not available.  Then once the option was clickable and the operation seemed to be successful, but not for long.

In all I have reinstalled windows back to factory default 3 times.  The first and second time the installation looked the same, the 2nd time it was completely different, it seemed to be a more basic install with fewer drivers (ie no wireless connections).  During install 2 I tried to bring back my backed up data with the Acer Backup Manager (stored on an external hard drive - to answer your question, yes I have a backup) but it stalled for 4 hours at 8% complete and I aborted it.  I have a recovery disc created when I used the Acer Backup Manager - here are several options listed but they either say they cannot run or do not run successfully and I should contact my administrator or the manufacturer.

Is there a way to freeze the blue screen when it occurs so I have a chance at copying down the info? They pass by so quickly, gone in a second or two, that I barely have time to register that it has occurred, let alone have time to read it and copy any relevant info. I could live with having to reboot several times before the computer starts but having it randomly tell me there is no bootable disc and then sometimes actually booting is frustrating.  I never know if I'm actually going to get the computer started or not. Once started it runs quite well for long periods of time.

Or maybe the info is stored somewhere on the pc so I can look up what errors it has encountered? I would like to try to solve this myself as I have no idea how much sending it back to Acer will cost.  But suppose if it is a hardware problem (hard drive failure?) then I'll have to send it back.

Thanks for your help!

I was running chkdsk one more time when the computer quit for good - won't even turn on now.

I contacted Acer from the web site, 2 days later I received an email telling me to phone Texas to find out how to send the computer in for repair.  Cost of phone call, shipping to texas ($80) and repair quote from email ($249) is almost half the cost of the computer.

I could just take it to a small repair shop in my home town because I haven't been able to find any links to local Acer service centers in Canada.  Or I could just buy a new computer.

Yes I specified I was in Canada - they had my entire address.

I couldn't find any info in the "repair my acer" section of the web site, and any searches I did of the community and the knowledge database brought up nothing.  So i went to the telephone and directory assistance.  Low and behold, the number they gave me was a repair line in Mississauga and now my laptop is expected in for repair.  I'm just deciding if I'm going to drive it there myself or send it by courier - depends on the weather.

I am kind of impressed with the flat fee repair structure, although part of me still doesn't believe it will work out that way.  Apparently the fee is $249 (plus tax) no matter what they have to do to it.  I asked the fellow on the phone how much more it would be if they have to replace the hard drive (which I think is now dead) and he said the $249 would cover it.  We'll see.
