The Full Tests take less than 5 minutes for most machines.
Once you have your Results, please post the
TechExpress Link back here into this thread for review.
Here's where you will see the URL address to post as a link to your Results:
Post the entire URL link information back here into this Forum thread.
Note: Vista users, please close your instance of IE "Running as Administrator" after you are finished reviewing your Results.
Caution: During the testing of Video Adapter, a variety of patterns, shapes, colors and text are “flashed” onto the users monitor screen. In the many thousands of daily uses of the PCPitstop Full Tests over several years, two individuals who suffer epilepsy experienced discomfort and temporary dizziness when viewing the flashing patterns.
If you know that you are susceptible to photo driven seizure, please look away from your screen during the Video Adapter testing sequence.
Note: The PCPitstop Full Tests Results is a free service, but is supported by various paid product advertisements for utilities that "could" remedy the OP's problem.
Since WTT is a "free-help" forum, we do not recommend or endorse purchase of automated utilities, and will assist you in manually correcting any problems and settings necessary to optimize your machine's performance. Ask your questions here. We'll help you walk through any necessary steps.
