Something has hit my computer hard, and I'm not sure what it is. Two problems remain consistent: One, my computer now takes much longer to boot up, and no longer shows me my BIOS screen, instead going directly to the Windows login screen after an uncomfortably long period of monitor inactivity. Two, my framerate has been absolutely decimated in any type of video game, even comparatively light games like Bastion, none of which had run with the slightest hitch (I've been able to run Bioshock Infinite at max settings comfortably, now the main menu slows my computer to a crawl). I believe it's possible that my graphical performance has gotten slightly but noticeably worse in the last few weeks, but now it's just ridiculous. I'm desperately trying to pinpoint the problem.
The other noticeable problem seems to be dependent on whether I'm using a VGA or DVI connection.
While using a DVI connection, this is what my monitor looks like: a mess of green, pink, and yellow pixelated distortion that is almost impossible to discern anything from. At first I thought it was connected to heat, as the problem would flicker in and out at first, but now it's just constant, as long as a DVI connection is being used, thus forcing me to switch to VGA.
I've installed a Cooler Master cooler, replacing the stock Intel cooler that came with my i2500k. I've dusted the inside of my tower, and installed a powerful fan in my room as I suspect the recent and intense summer heat (as high as 90 degrees Fahrenheit some days) may have caused some or all of these problems. I've replaced my power strip as well. While my computer has cooled down exceptionally (my CPU was running at ~60 C with almost no programs running and is now running at ~35 C under the same conditions) none of the problems have been fixed. I can't recall any significant changes I've made prior to this problem, although I may be forgetting something.
In an attempt to fix this, I updated both my Intel and Nvidia drivers, and I ran a benchmark on Furmark without any artifacts appearing. This is the first time I've ever ran Furmark, so I'm not sure how bad this score is supposed to be, but my results are pictured below if that helps anyone.
My specs are as follows:
Intel Core i5 2500K @ 3.30GHz
8GB Dual-Channel DDR3
Gigabyte Z68MA-D2H-B3 motherboard
GTX 560 Ti
1 TB Seagate SATA HD
DELL U2312HM monitor (1920x1080@60Hz)
Microsoft Windows 7 Home Premium 64-bit SP1
Thank you very much for whatever help you can give, I greatly appreciate your time and input.
