The SETI@home takes over and I can not access my computer. I have to disconnect the power and then restart. I want to uninstall it and reinstall but I am concerned that this may result in loss of data any help?

What is your configuration?
I have a similar issue with 3 x Asus Turbo 1080s and SLI.

cheers

Uninstalling BOINC & reinstalling it won't do anything else than remove the program from its directory and put it back.
Uninstalling BOINC does no damage to the data directory, everything in it will be kept in place.

As for your problem, tasks running on the CPU and GPU can add stress to the system, make everything slow. This can be alleviated by setting the preferences to only allow BOINC to run when the system is idle. This is the default setting for the GPU, but not for the CPU.
Also helpful could be to adjust how many CPU cores BOINC can use for calculations, when set to 50% on your system it will use 2 cores, leaving the other 2 free for everything else you do on your system.

If you still need any help on setting this up, let us know.

I see you are running at GT 710. In addition to having your gpu pause when you are active on your system I would like to suggest you use the Low end SOG parameters in your mb*sog.txt in your ProgramData/BOINC/projects/setiathome etc subdirectory. This is a hidden directory under windows so you will have to go into File Explorer and ask it to display hidden directory's.

From the documentation for stock Seti SOG for Nvadia cards it offers: " -sbs 128 -spike_fft_thresh 2048 -tune 1 2 1 16" w/o the quotes for entry level cards.

In terms of performance, my experience with a GT 710 under Stock Seti was something like 2 1/2 hours ~ task.

If you can locate a used Gtx 750Ti it will speed up the processing w/o impacting much of anything else. I usually got something like 15-18 minutes / task.

If you change cards I would look at the document text file to change your parameters.

You MIGHT benefit from an "app_config.xml" text file in your /seti program directory.

Its contents should probably look like this:

 <app_config>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
</app_config>


In general, to get "maximum" processing speed for the SOG application you need to devote a cpu core to it. If you want to increase the core but not dedicate a core I suggest:
<app_config>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>0.33</cpu_usage>
</gpu_versions>
</app>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>0.33</cpu_usage>
</gpu_versions>
</app>
</app_config>
