Since updating my desktop A4000 to a Power Tower
I have had to open the tower and reseat all
cards and connections every couple of months.
The first thing to work loose is usually my
graphics card. When I turn on the computer
it either boots to a blank screen or will not
boot at all. Once I remove and replace all the
cards and connectors everything is fine again.
I didn't need to open up my desktop A4000 for
years but my Power Tower requires regular
maintenance. Try reseating everything before
you run out and buy memory or anything.
