Vista - Really bad problems with graphics card and ram!?

Thanks i have sent it back i did underclock it! but oviously it fried my card a little bit. When u say you had to underclocked the ramm to stop is artifacting, Do u mean the ram on the graphics card or the physical ram sticks u insert! Please answer here
BSODS! Help

no mate im referring only to your GPU memory , your physical ram wont be causing that issue

Attached is an anaylsis made by debbuging tools of the dump I had (i say had cos i dont have it anymore, ccleaner must of got rid of it) ah well this should be okay!

Kk cheers now above is an attached copy of the anyalsis of the dump!

Edit: I also have lots of problems with right clicking as alot of the time it says windows explorer has stopped working. then it restarts explorer.exe and the taskbar comes back etc. but then its just a loop if i right click soon after!

I have lots of errors in memtest86+ on test 5, 6 and 8

5= 380 errors

6= 37

8=217

any overclocking of the ram? how many sticks of ram and what make/manufacturer/type and how many sticks do you have to make up the 4gb (eg 2x 2gb 4 x 1gb)
and is that the offline (bootable) version of memtest?

I got 2x2gb of ocz ram. ddr2-800

i need to know the exact type of ram mate/model number for example mine is OCZ PC2 8500C5.....there is a reason for this , some high end ram runs at 2.1 to 2.3 Volts especially the OCZ stuff now your motherboard bios by default will be sending out 1.8 Volts the the ram , it may be a simple isuue of upping the voltage to your DDR to solve the problem , if you can tell me exactly what ram you have i can see what voltage it runs at

This is my ram

OCZ OCZ28002G 2GB DIMM DDR2 PC2-6400U DDR2-800 (5-6-6-18 3-24-6-3)

Thats applies to both sticks!
Thanks
