Wierd blue screens and black screen (NOT BSOD)

Hello there,

Few days ago while I was fighting the final boss in ME1, the screen turned to lines of blue, sound frozen and nothing was responding. The red light was off.

Restarted, entered the windows, after few loadings the screen went black and nothing was responding as well.

Restarted again and got the same thing.

Closed the pc for few minutes and powered it on again and it worked fine for a day.

I always leave the computer on while I'm sleeping to download stuff, yesterday I wake up and I found yet another black screen, nothing was responding, restarted and found that all my downloads stopped completely few minutes after I went to sleep, so the black screen appeared just after I left the pc.

few minutes ago I was playing ME2, then all of the sudden the game crashed and got the sending error message, reran the game again and right after loading the save, it crashed again. Then I ran Fifa 2010 and during the 1st match the screen went blue.

Turned off the pc, and here I'm.

I would like to know what the hell is going on and what's wrong with my computer!! Is it the rams? the CPU? what is it!!

You can check your memory in W7 by typing memory diagnostics in search or go to control panel - administrative tools - windows memory diagnostics. Try updating your video drivers - 10.1 catalyst drivers are available now -
Graphics Drivers & Software

I already have that driver, will run the memory diagnostic and see what happens.

Okay, I just ran the test, during the 2nd test it said that there is a problem, but gave me no details whatsoever!! what's next? How to identify which chip has the problem? Do I really have to remove 1, test the other and vice versa or is there an easier way?

I think you might be able to download a utility that will identify the problem, but manually removing them and testing them one at a time might be the go, as you have to check they are seated properly in any case - here is a link -
