hi there, to start of: I'm puzzled, confused. you name it. that's what I am in the moment. until last week my computer was working absolutely fine. then, one day, I went afk for a bit. when I came back, my monitor had switched into power safe-mode. I moved the mouse - nothing happened. I hit the space bar - nothing happened. pressed on/off-button to restart computer. and that's the beginning of my nightmare.... computer started up... but instead of the normal long beep there was a long beep followed by three short beeps. and the monitor just stayed black (in standby mode). I searched (with my other PC) on the internet for the beep codes (not even quite sure, what bios I had) and worked out there must be a problem with my video card. so far so good. went and got a new video card, installed it. pressed on/off-button --> long beep, three short beeps. monitor black, standby mode. searching for other, else reasons i found out it could have to do with the pci controller. so I went out again and got a new mainboard. installed that last night. turned computer on --> one long beep, 8 short beeps, pause, 1 short beep (assuming it's AMI bios now). according to the internet this again indicates a problem with the video card. my last guess was that there could be a problem with the psu. so I went and got that today - to no avail. turn computer on --> one long beep, 8 short beeps, pause, 1 short beep. monitor black as nearly usual by now. now... I unplugged every single thing I could think of, tried to start the damned thing "standalone". all I get - whatever i do, is the succession of 1 long beep, 8 short beeps, a little pause and another short beep. (only when I took out my RAM there was a different sound going on and on...) in short: new mainboard, new video card, new PSU ... but the problem stays the same! what the heck is wrong? any ideas? answers, opinions, assumptions... anyyyything is highly appreciated thanks in advance!
