So I have been mining for a while but starting a week ago the screen started to randomly flash black for a seocnd or 2 then flash back to normal. Besides for that everything works fine. It doesnt break anything just is annoying. Does anyone know how to fix this?
PS: Stock everything and reachs a max of 77C with 77fan and 96-97 activity

It could be the monitor or the connection?

What's your reject rate?  It might show that there's a hardware problem (PSU or GPU probably).

100 rejects per 1000 accepted shares is a terrible ratio (10%). You're wasting time and electricity on those failed shares.
100 / 10 000 starts being reasonable. My miners are closer to 100 / 100 000.

Is that a Windows machine? Are any errors or crashes being logged in the Event Viewer?
What miner are you using?

I am usuing the GUI Miner on a windows machine, Also I recently Uninstalled catlyst 12.2 and installed and older version and it increased my speed and ratio. Now its down to about 50 per 1000.
Also How can I improve the Ratio?
What version are you usuing/what version seems todo the best
Is there a differnt Miner I could use

EDIT
Actully I might be wrong, In the miner right now I have 4238 shares but in parenthesis is says 198 but then it says Stale and that is 0. What does the 198 mean?

Q: What does it mean in the summary panel when the shares say something like 1000 (150) accepted?
A: That means 1000 shares total were accepted, including 150 in the last hour
Reading the FAQ doesn't hurt, really.
I take it you have familiarized yourself with the README, right?

GUI Miner is just a graphical interface. Which miner are you using? The actual miners that come with Kiv's Windows package include poclbm, phoenix and rpcminer.

Your stale rate depends on the pool server, your network connection to the server, and the miner configuration.
Pushing the Intensity (Aggression) too high for the card's hash rate will increase the stale rate.
