Hello! I am trying to solve my pc problems right now. I currently have a mpga478b motherboard. There is no display on the monitor. The hard drive is also not functioning because it doesn't have a red light on. The processor's fan is working. I have tried everything like cleaning the memory, video card, processor, heat sink, checked the monitor cables and IDE cables but same result. I hope you can help me. Thanks! Kris

try connecting it to aexernal monitor and see if anything is displayed, also check that your ram is properley seated and is functioning

please fix the processor fan properly.

this may not allow the processor to start

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive
Test the leads that attach to your ((hard drive from the motherboard)) or replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your ((motherboard to hard drive))
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections needs its connections continue its cycle and to have an end so any faulty leads will end up with a computer error
hope this helps

Will your system come up in safe mode? Try a shutdown and unplug the tower. Plug the tower back in and see if it will come up in safe mode. If it does, go to "control panel", find "device manager" and right click on it. Find "display adaptors" and click on box at right(has a little + inside), it should drop down your device. right click o it and you sjhould see 'enable" or "disable". If it says enable click on that ad you should be good to go. Make sure your connections between tower and monitor are good.

Hello,
If you unplug the signal cable from the mainboard, does the monitor display the message "no signal" or any similar? If yes, then try to unplug connected components to the mainboard (hard drive, optical unit) and see if pc starts. If no change, unplug power cord and remove the CMOS battery for about 20 seconds then try again.

in that case start system in safe mode after start safe mode please delet vga drive and then reinstalled it then after its worked.

if you have a video card in it try connecting it to the motherboards vga/dvi and see if you get any video. if not it could be ram/cpu or mobo if its not beeping my bet is on the mobo

This is the problem with the display capacitor on your motherboard. Try replacing the display capacitor by good technician. If it doesnt solve your problem you need to change the motherboard. But mostly this will solve your problem.

you have to put the proper secreen resolution. you do these
1. you checked it with another pc when it shows the screen then change the display properties screen resolution as minimum lke 600X800.
2. you also change the screen refresh rate to 60 Hz to solve this problem.
ok
thanks
