I took my daughter’s hp s5713w to the shop for repair, as it will not display anything on the monitor. They thought it had a virus, stated I could pay them $170 to save her data and reinstall windows 7. I chose to reinstall windows myself, but could not get her pc to display anything to be able to access dvd. I used another pc for imaging (Dell Inspiron running vista home premium). Afterwards, HD seemed to be working fine on the imaging pc. Her pc still does not have a display after reinstalling hd, pc used for imaging has developd similar issues- interested speckles of color blink on monitor, problems follows both pcs if connecting to another working monitor. ARGH! Help! Can’t afford to have a “professional” repair these pcs, still have 9 kids at home. 😉
