No one here is obliged to help you and using 'text speak' and acronyms such as 'ffs' are reason enough for me to delete this thread, so roll your neck in and exercise some patience.

Just exactly that, no one who use this forum is paid to do so thus there is no obligation to post anything at all.

oooooo ok i under stand but please help me if u can

I would suggest that your problems may be driver related but making such suggestions always seems to get the ATi fans worked up into a bit of a frenzy.

no no im cool but what drivers because i have latest drivers for everything

Try the older drivers and see if one them makes the problem go away.

If you want to find out if the card is throttling, download MSI Afterburner or GPU-Z and monitor the clock speeds while you attempt to play. See if the core clock is dropping or not.

no monkey have had the old drivers installed aswell also happened and would my card throttle because of psu

Weak PSU's tend to cause BSOD's, lock up's and/or error boxes popping up, throttling back when it shouldn't is a driver or BIOS (on the device) issue.

A darn decent PSU can never be a bad investment IMHO.

Corsair is a reputable brand, and 600W is a good size for today's single GPU systems. It should give you some room to protect yourself and overclock should you choose.

I believe mm was saying that he also likes Corsair, as he's had great success with them.
