So the first problem I got is the one posted in the subject. My computer doesn't respond if I let it go to sleep, I have to take out it's source of electricity, wait for a small green LIGHT in the computer to go out and restart it after (when I do so tough it does actually reload what I had open when the computer went to sleep). It doesn't respond using my mice, keybord nor hitting the start button.

Then I have two problems that I think are related to my graphic card. The first one being my screen SHOWING small lines of light and dark when I play computer games (Starcraft2 and WoW and some other games I've sen it on), which should be something to do with the refresh rate of the screen. Indeed how visible the lines are and how the lines act (they move up or down or stay put in the middle of the screen)  changes if I put on or off vertical sync in the game. It also changes if I play full screen or windowed, but the lines are still there.

The other related issue is my cursor graphics is bugging out at times, basically it'll be loads of lines instead of the white pointer/arrow thing it normally is.

The graphic card I use is Sapphire Radeon HD 5870 1GB GDDR5.

Oh by the way I use windows 7. For some reason it says unknown.

Any help would be lovely <3

Sincerely,
Theovide.I made this in kind of an hurry and now realise it might have been put in the wrong part of the forum. Though as it's SEVERAL problems I'm not sure where to put it otherwise, but if any moderator or such knows a good place for this I wouldn't mind having it moved .

I also realised I didn't post what screen I'm using, which is a Benq G2420HD. Though according to a guy having the same problem as me, also with sapphire radeon card (not exactly the same one though) and a Benq screen, chaning screen to another one didn't solve his problem. Then again he might've been so unlucky that he got another unworking screen.

Anyway thanks for taking the time reading, if you did.

This is the receipt or likewise from when I bought the stuff, hope it's enough .

Also, I've managed to reduce the flicker related problem slightly by updating some drivers aswell as putting the screen into it's own electrical output (and not into one who shares one electrical output into many). So it's not as much as a problem anymore, but if you know any sollutions that would still be great of course (right now I can't play in windowed [fullscreen] mode on my games because that increases the flicker somehow).

Cheers for any help

Where do you live? Is your area 50 Hz power?

Is your area 50 Hz power?

What difference does that make? 50 or 60 Hz, it gets turned into DC by the power supply.

It matters. The power supply has ripple. A better power supply might help.PSU ripple is more annoying when using a 50 mains and refresh rate of 60.

Theovide: have you tried reinstalling the Sapphire driver?

This.  Make sure you're running the latest driver, which is 11.4 hotfix.

As for the sleep issue, do you know what BIOS version your motherboard is on?  If it's not the latest, update the BIOS first, but make sure you do it through the Asus EZ-Flash in the BIOS, not through Windows.
