Question about Acer Aspire T690 (AST690UP820A) PC Desktop
Can get the power light, hard drive working light to come on, but continuous high pitch audio sound from the tower....no monitor picture....will not start nor acknowledge recovery dvd in drive. Have to shut down by holding down power button. Will not respond to Ctrl/Alt/Delete
While computer operating fine, young son hit Ctrl and Esc I believe simultaneously and went into the described mode.
Not sure if this is the final problem, but I removed one of the stick of RAM and tried powering up and it started! After waiting forever for my system to boot up, I shut down and re-installed the memory and it's running fine. If it does it again, I may just replace the RAM altogether.
