Graphics cards acting up

Hi new to the forum, I think this is the right place for this thread. I was wondering if anyone could offer any opinions. This is my system:

XPS 420
PSU: G7 Power Extreme 780W
CPU: Q6660 @ 3 GHz (BSEL Mod)
GPU: Asus Radeon HD 6770
RAM: 4GB DDR2
OS: 64 bit W7
HD1: 1 TB 7200 Rpm
HD2 500GB 5400 Rpm

I did have a stock PSU and 8600 GTS GPU. I kept getting errors when watching flash online where-by the flash screen would go green and a message would pop up saying the GPU recovered from an error of some kind. Then the other day my PC wouldn't power up, the fan over-ran and I got an error message 1-2-3 if i remember correctly (not sure). I looked it up and found that it was probably the GPU, sure enough when I removed it, it powered up. Went out and bought a HD 6770 and a bigger PSU because the stock dell one was 350W and the 6770 box said it needed more. New GPU and PSU installed, games play great but low and behold when playing flash online the entire screen goes either black, blue or stripy green lol. When this happens (on both monitors) the pc stays on but nothing functions (ctrl-alt-del etc, nothing). Ive tried switching the PSU's back and that does nothing. Soooo.....

Could it be... my mobo is wrecking graphics cards... :eek: both the PSU's ive used aren't up to scratch (the 780w one was only £40), the 6770 isn't working correctly (I dont know how often out of the box graphics cards fail) or a software issue. I'm 99% sure I have no virus's.

Sorry for the long winded post, just wanted to get some opinions :D

Thanks :good:
 
Yea got the latest flash, also tried with and without enabling hardware acceleration, I'd suggest it might not be flash but i can't get it to crash when gaming or watching video files.
 
How did you install the graphics card. You should have gone this route:

uninstall old gpu drivers and shut down.

Install new card

Go to ati.com and download latest driver and install

Restart
 
Didn't do it in that exact order, couldn't start it up with old GPU, so popped new one in, installed drivers and removed old ones. At the moment I've totally uninstalled flash and I'm gonna see if anything else causes the freeze, could just be coincidence i guess.
 
Ok I fixed this problem myself, got rid of flash for the day to make sure it was definitely the cause. Had no crashes, did some GPU stress tests etc, still none, put flash back on, 2 crashes in 10 minutes. Went hunting around on other forums and found this advice.

If you are having conflicts between flash and your GPU/GPU Drivers install flash version 10.0.x as it uses hardware very differently to the newer versions. (Also disable auto-updates).

This has fixed all my problems, thanks for your help though
