Computer freezes after login, even after clean install

[gibari]

Hello, my computer has been freezing for the past few days every time I try to login.

It will sometimes give me a pink screen, I got in once but the screen went black in a couple minutes.

I can login in safe mode fine and even normally if I do diagnostic mode from msconfig.

I tried repairing windows 7 startup, but it detected no errors. I tried a clean install but the problem stayed.

all help is appreciated

Sounds like a video card issue. What are your complete computer specs, and what kind of video are you running? On-board or separate video card?

Ok updated info
After login screen goes to black and white marks appear at the top and it loses connection to monitor sometimes but if I wait 5 min it logs me on normal and it appears to be running.

my GeForce GTX 570 is reading a 61 degrees Celsius in speccy

This may indicate a dying hard drive...

Any way to be sure? I managed to get my video card down to 33 degrees celcius after repositioning it and dusting and installing latest drivers

Those white dash(s) on a black screen means that the computer can't find the hard drive, so that's a clue. You can check the drive for errors by going to computer, right-click on the C drive, tools, and check for errors
