Graphics screen corruption - random noise, flickers,etc
Hi All
I have a problem with my year old desktop pc and random screen corruption when I startup the pc. Sometimes it does it once a month, but in the last week its happened it every day.
This is a video of what happens but its not always the same, but its always at startup. Usually anytime upto and including the windows login screen, but never before or during the bios screen. Once it corrupts I then need to hard reset, soft reset does nothing. Also, after a successful reboot windows complains of a previous bluescreen. All drivers are up to date.

I`ve tried replacing the graphics card and I still had problems and i`ve reinstalled windows 7. I`m thinking the next thing is to replace the psu? Whats strange is that it never goes wrong once windows is up and running, its only at startup. It also cause the external monitor (TV) to blank out and it freezes the pc ie caps lock,etc dont function. i`ve also tried it in someone else`s house with different monitor and the same occurred.
