Hello all, first post here with something that has had me scratching my head for months. I have a home built computer running an MSI HD 7850 2GB video card hooked up to an old LG flatron W2243S VGA monitor with a little DVI converter which displays at 1920x1080, when i first put it together last Christmas i took it to my local computer shop to have windows 7 installed, got it back, no problems always loaded up at the correct resolution. Probably around 5 months ago now i had a problem with my computer where it would just blue screen randomly, took it to the guy who installed my windows 7, he fixed the problem and gave me the computer back. About a month later, i started my computer up and it started displaying at 1600x1200, there is no option to switch back to 1920x1080 in the display settings in control panel, so i have been forced to wait for the incredibly slow AMD Catalyst Control Suite to load up after start up, so i can untick the "Use Extended Display Identification Data or Driver Defaults", which then opens a drop down menu and i can select 1920x1080, hey presto its back to normal! However, every time i restart my computer it loses these settings and i have to do the whole process again which adds 10 minutes onto my startup time, I know the man who fixed the problem doesn't have a 1080p monitor and so maybe this is the problem, i can't take it back to him because he can't see a problem as obviously his monitor doesnt support 1920x1080, could the computer be confused and think that 1600x1200 is the native resolution? Also, sometimes when i try and play a video on youtube whilst doing something else, the screen will start flickering/go black and just display little random lines scattered about, i can still hear sound and the computer still functions but obviously i can barely see the display, this can sometimes be solved by using Ctrl + Alt + Delete to bring up the menu and then closing it again, or sometimes by just Alt F4'ing the youtube video, sometimes this does not work and forces me to restart my computer, extremely annoying when playing an online game. could this be due to an outdated monitor?
Many thanks in advance and apologies for the essay, but i've been putting this off for so long and i don't know where to turn if the man at the computer shop can't even help me! I am running windows 7 64 bit, AMD Black Edition 3.5GHZ 6 Core processor and the MSI HD 7850 2GB Graphics card.
