Red dots on the screen can be a couple different issues; burnt out pixels, failing GPU (in this case the i7-3770k), bad motherboard, etc.
Can you provide me a copy of your dxdiag for review? (Start -> Run -> dxdiag -> Save All information).
Now My screens doesn not show almost at all ( 2-3 secs / minute ) , can I give to you the file in safe mode ?
and thanks in advance !
Just copy and paste the text here!
I will say though, if this issue is getting progressively worse, it definitely sounds like a bad hardware problem. If you can, try using a different cable and see if that fixes anything.
OK let me clear some points :
Built the PC less than 2 moths ago , bought also new cable and new 27" screen . when I installed OS I used that screen , used it another day , then replaced it with another one , the MOBO has only HDMI output , the first screen had HMDI input , the 2nd had DVI so connected with HDMI TO DVI cable for about 5 weeks or so ,,,
dont know what happened ( drivers updated or HW issue ) but I start getting red dots on the screen and mere flicker , thought it was the screen cuz the PC was too new ... so I sent the screen to the lab to fix it ( seems it was good screen ! ) and connected the 1st same screen I installed the OS with with HDMI CABLE ...
and I started to get more flickering and blinking and the same red dots ...
changed cable , didnt help , connected the screen to another PCs works fine on the ( with the same cable ) ...
in safe mode I can log in without much flickering ... so uninstalled the graphics driver ... the problem was still there ,,, installed many different versions of the graphics drivers and when I boot into normal mode I get almsot no screen now ...
so I am having trouble posting the thing you asked in normal mode :s
Dont ask me How I managed to get the file out of the blank screen ... but here it is :
here is another log when I deleted the graphic driver driver
it detects a VGA graphics somehow ...
waiting for your reply !
Thanks for the information. It looks like you're using an out-of-date and/or default driver. Go ahead and install this one; http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22083&lang=eng&OSVersion=Windows%207%20(64-bit)*&DownloadType=Drivers
Let me know if there is any improvement. Though it still sounds a lot like a failing hardware issue; do you have another processor and/or motherboard you could swap out and see if you still get the red dots?
The driver didnt do any better ..
The annoying thing is that the PC is less than 2 months old ...
I bought it from intel USA , and I live in Israel ... so now I will have so many troubles to replace parts if you are saying it is hardware issue .. :s
