My monitor would take a long time to come out of sleep mode and after trying to update drivers trying to fix it I regrettably reinstalled Vista Home Premium from discs on my Dell Inspiron 531 Amd Athlon 64x2 dual core 4400 2gb ram with ATI Radeon hd3450. Turns out it was a faulty monitor. Now most of the updates will give error code 80073712. I read about the system file check tool but cannot access it as Im stuck with outdated Internet Explorer 7 that will go to the websites buth the say it cannot open them and Im unable to update it. Any ideas to fix this? I know its an old computer but just for everyday internet it was fine.
