I just got a new Sparkle 9800GT with heatpipe cooling. and havnt been able to get it to work.
It displays on the monitor alright but then scrolling down web pages or moving anything is really jumpy and makes the cpu spike. ive tried downloading new drivers, deleting drivers, booting in safe mode and installiing, using driver cleaner etc. and nothing has made any difference, i just occasionally get a BSOD with either "PFN list corrupt" or more often "Memory_Management" on it. (the BSOD is usually just after an attempted driver update, on the reboot)

all the connections inside the pc are correct, ive taken it out and put it back in at least 3 times and it has the power cable connected to the back.

right now iv switched back to a borrowed 7400 and after a delete and reinstall of driver, its working fine.


Any ideas what could be wrong?


useful info:

intel e8500 3.16ghz
ASUS P5Q-E Mobo
3 seagate SATA hdd
650w Antec earthwatts PSU (so i dont think thats the problem)

Thanks in advance
