Blue screen all time

Hello. I got the following problem.

I have an Acer Aspire 4738 with Core i3 M380 with 2.53Ghz. When i buy it i increase the memory to 8Gb. I had windows 7 and one day it starts to give me errors, blue screen errors. I got blue screen lot of times and it seems that it happened when i was in explorer or chrome. I though that it was a problem with windows so i instaled windows 8, but the problem persists. Last night i remove one of the memory cards and let it only with 4Gb because i thought that maybe it was a problem with the supported memory, but the problem continues. I get blue screen even if i turn it on and not using the laptop, it happens like 4 or 5 times a day.

Can you help me please? how can i send you the files that contains the crash info?

Thank you very much.

Can you post a report from windows event viewer?
