Blank Screen

Clarifications

you may be able to search and find an error code...but, it sounds as though the
video has gone bad. If this is "on-board" video, you can maybe install a seperate
video card, then in BIOS setup disable the onboard video.

From memory - this indicates a video card failure. Here are all the beep codes from PC Hell

Have a look

Hi There are 2 1gig Memory sticks, They were fitted brand new less than 18 months ago, I started with the memory as i removed all hard ware, one stick at a time, then restart the computer and the same long beep, then the other stick was removed, same thing happened, then the video card was removed same thing a long beep about 5 seconds then a 5 sec silence then a 5 sec beep continuance, i removed every thing of the board 1 at a time untill i had a bare board with the same beep, Thanks Jamind

This all depends on the GPU, is it onboard the MOBO or a plugin?? A memory fault will give the continuous beep when the first bank or in the Flash memory fails. No display would indicate the video BIOS on a plugin card failed. Onboard is more complicated but easily disabled to install a plugin to bypass the fault or for diagnostics.

see if you knocked the cpu fan loose or off center or unplugged it. It sounds like cpu overheat warning. Even if it does not look askew I would reseat cpu fan, memory (watch out for fan power lead) and external video card in that order. One other thing to try is unplug keyboard or mouse if above does not change anything. Also chang jumper to clear cmos and leave it without any power plugged in for 24 hours. Sometimes bios just locks up when memory is not seated correctly. If none works then time to upgrade as mb likely shorted.

Hi Guys, Im so Sorry for not replying sooner, I found the Problem with Compaq Presario S1050AN Desktop Computer, It was 1 of the 1gb Memory Sticks that had stuffed out, Also i think i know how i missed it when i was hunting the problem, When i started looking for the blank screen problem i pulled out 1 sticks of Ram at a time & carried on pulling every thing of the board 1 at a time still getting the same long on of beep. I left it stripped for a week, It just came to me after reading all the info you guys had sent me again, i reassemble the desktop & wipe the memory teeth to take the build up of them fired it up getting the same beep, I pulled out just the Num1 stick of memory fired it up & there was a screen, well i could of kicked my ass if i could, as that was my mis tack, Both Memory sticks should have been wipe down first time they were pulled out, the problem presented itself after this was done, Thanking you all for your input in helping me relies the stuff up i made, Soch a small Problem was doing my head in Ha Ha, Thankyou Jamind
