I own an e-Machine T6532. My CPU is running when i boot it up but themonitor always display "No Signal Detected". Sometimes when i get luckyI got it to work, but the graphic sucks. And when I'm really lucky, Igot it to work perfectly like when i just purchased it. I think thatit's my in board Graphic card since i do not own an external graphiccard. What should I do? Do you think it would fix it if i buy a newexternal graphic card and install it?

Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU. It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.
you should not leave PC on for more than a couple days.
It may have gone into Hibernate and if there is a bad sector, (i.e. read errors,) when that is loaded into RAM, then that can cause many symptoms. Try to boot into Safe Mode, then if that works, Restart and use Normal mode.
it is your graphic card is detected? check at device manager. Try update through internet. If not working , restart and click F2/DEL, something that will enter you to cpu setup. find your display. change using of graphic card using (default internal memory-if grphc crd is nt detected).
sometimes the fault is not always from the graphic card ... it could come from the processor or the memory .... please check them too and also check the signal cable especially the pins on the signal plug
Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.
Perhaps these simple trouble shooting procedures will get the job done.
1. use the DVI to VGA adaptor that came with your card
Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary
2. plug in the your LCD monitor on Secondary Display port using your DVI cable
At this point you should be able to see your desktop on the Primary CRT Display
3. Go to the display properties and use the Nvidia Dual Display Setup Wizard
set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel
If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )
At this stage both displays should be showing a Windows Desktop
If you now see your desktop on both displays , you can now put the LCD on the Primary Port
No Signal Detected ( this means the display device is not receiving a signal )
If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.
If you are certan you have done everything correctly but still see only "No Signal Detected"
Bad capacitor(s) on the motherboard can cause this problem, corrupted BIOS maybe... try flashing BIOS.
Probably the CPU if your not getting any error code beeps on startup.. NO Processor for the BIOS instructions thus no Beeps !
This would usually indicate that there is a problem that is causing your computer to not boot correctly all of the time. What you have described could be many different problems and without more information I cannot say which one it is.
1. Hard drive. I have ran into Hard Drives that for some reason do not start up correctly right away when you put power to them. This can cause the initial startup to hang possibly indefinitely. 2. Video Card. Something probably firmware is causing your video card to not start up properly when power is first applied. 3. PSU. The power supply could cause similar problems if it cannot supply enough power because the highest power draw is when you first turn on the computer. When you push the reset button the power is already being supplied to most of the components and the ones that did not have enough power to start properly before can do so now. 4. CPU. If the CPU has some minor problems it can cause similar problems. In any case to fix it you can try clocking down the CPU but you are better off replacing it. 5. RAM. I have had similar problems with RAM. Clocking down the RAM fixed the issue. 6. Settings in BIOS. I would check to make sure the setting for init display on boot is set for PCI-e.
