First of all, thanks for a great resource. I found this forum during a few Google searches, and decided to sign up because it would appear you actually get worthwhile assistance here (thumbs up). Especially koala seems to be very active! I digress...
Inspired by these threads:
Red/Blue dots and video turns off and on
Red dots appear on screen
(my problem appears to relate a lot to this)
I was watching a video clip, and all of a sudden both screens stood still and a red dots appeared. Both the mouse and keyboard became unresponsive. I shut down the PC manually and when it rebooted I could easily see dots in BIOS/POST. I proceeded to boot in safe mode, and while it did boot into Windows (Windows 7 Pro, 32 bit), the dots and lines were still there.
I let the computer cool off for half an hour and restartet it again. Now it seemed fine, but as you can see from the screenshots below, there definitely is something wrong. Also, check out the temperature the GPU is running.
Screenshot of the dots in BIOS:
So my computer is a couple of years old. I built it myself, and the specs are as follows:
ASUS P5B Deluxe AI Lifestyle Series
OCZ Enhanced Latency 2 x 1 GB
Core 2 Duo E6700 2.66 GHz
Sea Sonic S12-600 (600W) (PSU)
I use 2 dell LCD monitors, and the error (blue and red dots) appear on both screens, so I can rule out the monitors as having the issue.
In the before mentioned threads, the suggestion was to run the GPU-Z app, and so I did. Here are the results:
I realize the GPU temp. is extremely high. This test was done running absolute nothing (basically just looking at the desktop and running GPU-Z).
I figure this has either something to do with my graphics card or the PSU. I would like to get some input on what o try, as I don't want to switch the GFX card if it's the PSU that's the problem.
Thanks in advance, and let me know if you need additional information.
