Windows 8 sleeping problems on vaio E series

[funnystone64]

Hey guys. Recently i have had some issues when i try to put my laptop to sleep. When i close the laptop lid my computer is supposed to sleep. But around 2 weeks ago when i would close the lid it would shut off the screen and not sleep. The fan and all the LED's were still on and i could not turn the screen back on. I have tried everything i could and researched a bit but i couldn't solve this problem. i also did a clean install of windows 8 which somewhat fixed the problem. By that i mean now it can sleep once but if i try to close the lid again in the same boot the problem happens again. I have no idea what im doing to prevent it from sleeping. it was working fine 2 weeks ago. I have a sony vaio running windows 8 64-bit with a intel core i5 2450m with 6 GB of Ram. If you have a solution try to be clear . thanks!

If you have an AMD radeon graphics card, then if I remember correctly, it is a driver issue. Try to either upgrade or downgrade your driver to check if it really is the issue.
