Thanks for the info. However it would've helped if you'd answered some of the last questions also. LW should not cause your comp to restart. I hope you've checked your computer over with reliable antivirus, anti spy& adware utilities.

If you have changed your graphic card settings, try setting them back to default to see if it helps.

Other than that, Tip: Purge the Downloads Queue! (click on link) & if you have large shares of files, reduce them a little.

* After opening LW wait 10 to 20 mins before using. Let it settle down 1st.

* Go to LW's prefs>Speed & tick disable Ultrapeer Cap. & press apply button.

* Set both uplds & downlds to autoclear.

* Reduce uplds to about 70-80% or more.

* Don't use the Resume button on all incomplete files. This can have side-fx such as affect LW's connection quality. May queue your files for much much longer. This will also stress LW & your comp. If you use Resume/Find sources then just apply it to a couple or so at one time.
