Led pwr+hd isn on, cpu fan is runing, but no

there a cmos battery in there the size of a nickle

Check the NUM LOCK led status when power on the computer if it is on and off when you press num lock key that means your cpu is working fine only issue with screen resolution for that when you power up th computer press F8 key 5 to 6 times then you can see safe mode and other menu.Enter in "enable vga mode " then go to display settings change scree resolution to 1024*768 then check. but if num lock led stay constant then open cpu cabinet cover reconnect RAM memory.Pull cmos cell from motherboard for 10 minutes then put it back. Reconnect pci or vga card if any. Reconnect processor and it's fan. Make sure motherboard is not ground with cabinet.Also make sure harddrive is recognized in bios if you are able to see bios. For that when you power up the computer press F1 or F2 or del or ALT+F2 key to enter in bios then check. Let me know if you need further assistance. Thanks for using Fixya.

have a problem with v1.5 a6566ims always ask if in start setting bios date month and year, and the second when the computer restarted there was no display on the monitor even though I have changed battere, VGA or memory, whether the BIOS has been damaged? what should i do please help. thanks

When you power up then after 12 seconds check the num lock led status on key board press num lock key then if num lock led is on and off then your cpu is working fine.
For that make sure vga adapter from monitor is connecxted to cpu is properly.Then when you power up the computer press F8 key then you can see some menu enter in "Enable vga mode " then go to display property and change screen resolution to 1024*768 then apply and check.
But if num lock led is constant then then you need to open cpu cabinet cover.
Then reconnect ram memory .Try it in different ram slot.Make sure motherboard is not ground with cabinet.REmove pci or other card if any.
Then check.
Pull cmos cell from motherboard for 10 minutes then connect again.
Also reconnect processor and it's fan then check.
Let me know if you need further assistance.

First check num lock led status on key board when you power up the computer if it is on and off when you press num lock key then your cpu working fine but if it is constant then you need to open cpu cabient reattch the RAM memory pull cmos cell from motherboard for 10 minutes.Reattch the processor and its fan.
make sure motherboard is not gorund with cabinet.If you have vga card then reattach into its slot.
But if num lock led is on and off then when you power up the computer press F8 key then enter in enable vga mode then go to control panel->display property ->settings then change screen resolution to 1024*768 then apply and ok.
Let me know if you need further assistance.

Press num lock key of key board if num lock led is on/off then your cpu gives display to monitor Then make sure monitor cable is connected properly to cpu vga port.
When you power up the cpu press F8 key then enter in "enable vga mode" Then go to start->control panel->display->settings.
Change screen resolution to 1024*768 then apply and ok.
Then check.
But if num lock led is not on/off and left constant then you need to open cpu cabinet.
Refix RAM memory.Pull cmos cell from motherboard for 10 minutes.
Clean dust from all parts.
Reattach processor and it's fan.
Make sure motherboard is not ground with cabinet.
Open motherboard from cabinet and try outside of cabinet.
Let me know if you need further assistance.

Hear some any beeps to your motherboard. If your hear this beeps then motherboard will identify what is the loss connection of trouble of your MOBO.
If you don't then have to remove tor clear the CMOS by removing the Lithium Battery in it.
Good luck!

First check your num lock key led if it on and off when you press num lock then your cpu gives diaply to monitor perfact.
Then check your display connection from monitor to cpu.
When you power up the computer pressF8 ket then enter in enable vga mode.Then go to control panel -> display->property ->settings.
Then change screen resolution to 1024*768 then apply and ok .
But if you still not get dispaly then

-> Open cpu cabinet.
-> Refix RAM meory clean all dust from motherbord chip set .
-> pull cmos cell for 15 minutes.
-> Reattch ATX power supply to motherbord.
-> Refix processor it is bottom of processor fan.

Please rate my solution if it help you .

Im gonna take it that "yup i'm hear the any beep" means you do hear a beep.

So first If it has an onboard vga card. remove the second vga and hook the monitor up to the onboard and try to boot.

Second try the Power Supply, make sure whatever power supply you use has enough to handle all the equipment in the unit.

If those two don't solve the problem, then you have a bad motherboard.

Fix your ram after cleaN IT AND ITS SLOT ALSO CHANGE RAM .PUT YOUR CMOS CELL FOR 15 SECONDS SO YOUR CMOS SETTIGNS ARE RESET.
