Title: nothing comes on monitor
Post by: x455 on July 21, 2008, 07:52:10 AM
I built this computer about a year ago.  I had it working for about 2 weeks before I decided to be real stupid and plug it into the wrong power voltage (i was in korea) and it made a pop sound and basically blew up.  I was hoping it was just the psu that had went out so I replaced that and when I powered it up, everything seemed to go fine except nothing was coming up on the monitor.  HDD is good because I gotta hold down the power button to turn it off like Windows was popping up or something.  So I figured it must be the graphics card, so I replaced that and still nothing on the monitor.  And then I decided to go big and replace the mobo, and guess what...still nothing.  I'm kinda getting real sick of basically buying a completely new computer so if anyone could help me out, that's be real cool.  Here are specs:

AMD Athlon 64 X2 4800+ AM2 Socket

Hello X455. I am thinking that the pop sound was made by your monitor and that is the only part that has blown up. Please try another monitor, if you can, and see if the problem is resolved or not. Let us know how it goes. Good Luck. :)

i'm pretty sure it wasn't the monitor that popped.  my face was right next to the psu (i was trying to figure out where the burning smell was coming from) when it popped...i thought i died...just sat there frozen for a good minute.

Whatever might be the case, we still need to confirm it is not the monitor. Do you have a spare  working monitor that you may connect to test with your computer?

yea...i guess i could still try that out.  the monitor has been through 2 gov't transports so that might be it.  when i turn the computer on, the monitor auto-detects between vga and dvi...and after going dvi (which is correct) it goes blank and then the little light in the on/off button starts flashing (power save...i don't know it's called when it does that...i think it's power save)

Hmmm... what you are making does make sense. Anyways, try replacing the monitor and see if the problem still persists or not. Good Luck. :)

i put another monitor, that i know works, on this system.  it's an older crt monitor, but it was working before and after i put it on my system.  still nothing...well actually this time it gave me the check cable message...but my other monitor (the one in question) will give me that message when it's disconnected as well, so i think i'm still at square 1.
