Hi, I've been running on my recently upgraded system for about a week without any problems but today, nothing came on the screen when the computer was turned on.
All the fans are working and parts aren't loose or anything but there is one beep followed by a long pause then 3 fast beeps during the booting process. I didn't find any problem with the memory so I took out the graphic card and plugged the monitor into onboard graphic card which is hd4200 or something. The beeps are still present but it boots up normally.
Does this mean that my new graphic card is defective?
Do you have AMI BIOS on your motherboard ? Acc. to AMI BIOS doc., 1 long & 3 short beeps means conventional and/or extended memory failure. This, I believe, is the area below 1 MB of memory section. Therefore, your gfx card should be O.K.
