I've tried everything I can think of to keep four SETI v7 GPU tasks from crashing my video driver (short of spending actual money). I've installed the latest driver (inferior to the older one, it seems), tweaked all my overclocking and BOINC settings and given these tasks exclusive use of this machine. But the driver invariably pukes after a few seconds and task progress stops after it reloads itself.

It's an older AMD 5400 card in an i7-2600K machine running Win7. Can anyone come up with more things I should try before I give up and abort these four tasks?

As a start, I would remove any over clocking and only run 1 task.

If that works, move up from there.

Well, the 5400 is about the weakest ATI5 card there is. The weak ATI/AMD cards have problems running MBv7 and will probably not be much faster than your CPU even when working at it's best. Anytime you start replacing drivers, especially when going backwards, there are steps you should follow. Most of them are in this thread, http://setiathome.berkeley.edu/forum_thread.php?id=76891. My suggestion would be to delete the binaries as in this post, http://setiathome.berkeley.edu/forum_thread.php?id=76891&postid=1653221#1653221, then Run the Driver Uninstaller in this post, http://setiathome.berkeley.edu/forum_thread.php?id=76891&postid=1654109#1654109, and then install Catalyst 14.12. 14.12 seems to work well on my machines. It's up to you if you want to use the newer ATI MBv7 App mentioned in that thread, but the newer App is Much better than the r1831 you're using now.

Good Luck.

Adding to what TBar mentioned about making sure you get all bit of the old driver out before installing a new one.
BOINC is reporting your GPU as "AMD ATI Radeon HD 5400 series (Cedar) (1024MB) driver: 1.4.1741". Which indicates drivers 12.6 to 13.4. Cat 13.1 is known to have an OpenCL bug & is defiantly a no go for SETI@home. MY HD5750 is running fine with Cat 14.9, but that version has an issue where the Control Center can crash sometimes. So I use Cat 14.4 on two of my other system.
