I searched a lot for this problem and found this forum via google.Lots of people are having same problem here also.I have detail explanation of my problem below,plz be atient.Hope you guys can help me
Now,here is my problem.It started about 2 weeks ago i think but not sure.When i was plating MAfia 2,screen went black and the monitor's power signal was going on/off.Nothing worked so i have to restart my computer with restart button.No bluescreen message nothing just black screen.Then it started happening in other game like PES 2010.But the black screen appears only when the 3d is rendered i think cause the game menus works fine.As soon as the game is started,the blackscreen appears randomly.sometime i can play for 1/2 hr,sometime immediately after starting the game.
So i reinstalled new driver(latest),used driver sweeper,cleaned my cpu case,blew some dusts,removed gpu card(msi 9800gt) and placed it again.
After doing all this it worked until 1 week i think.All was going well till 2 days ago it started happening again.This time all my games crashed immediately after starting them(no crash in menu screen).I checked GPU team in gpu-z and msi afterburner and they are fine.(idel 55 C, on load 78 C).so i again reinstalled nvidia driver,removed my cpu case and just unpulgged and re plugged my HDD cable,fans power cables and now the games working fine.
But i was curious what it causing the problem and googled a whole thing and found out about driver issue,MB issue,bios issue,driver issue,PSU etc in various forums.I also came to know about verifier.exe in Windows 7 last night and the dump files.i tried to check dump files but due to some problem it doesn't show correct data.On one file i found something like dxgkrnl.sys and nvlddmkm.sys.I then ran verifier.exe to check these two driver and it restarted nornmally without any bluescreen.However everytime i started verifier.exe to check all the driver it showed BSOD after windows started.
So please guys help me to find out what's causing the problem.Is it hardware issue or some driver?I have explained lots of things and attached the dump files.Hope this will help
