Make sure the video card is good and also that it is seated in the slot properly. You may need to actually remove it from the slot and push it all the way back in to reseat the card to make sure it is in all the way.

I have a PI865D7 mercury motherboard when i start the pc, computer turn on fan is running all light on but no display in moniter i check the ram, it is ok so please could you help

you may re-seat your ram, video card and processor and pci cards. Turn it back on and see if that works. If you have to do that often then your motherboard has a bad connector or socket on it. If you just installed somthing on your pci slots take them out. If re-seating your ram video card processor and pci slots doesn't work, remove all pci cards and try, If that method works, install them 1 at a time and see when it stops working to isolate the problem.

Good luck hope your motherboard isn't shot,

In short, yes you can upgrade to a P4 cpu but from the compatibility chart at Intel support, it looks like the upper limit for this older board is the P4 2.6GHz.

Note: Even at that, running the P4 2.6 would require a BIOS upgrade to P12 or greater.

Luckily, the following link has the information you seek: (for BIOS info, click the "BIOS Version" link in the upper right corner of the compatibility table provided)

I hope this info is helpful!

Hello every 1 d845hv

If it is only since removing the ram and re-inserting it that there is no display, try removing the ram again and re-inserting them 1 at a time then switching on to see if there is any display. Make sure the ram is firmly in place in its socket before switching on. Also you do not mention if there are any beeps coming from the internal speaker when switching on. These beeps sound different for different problems and the way it beeps can tell you where the problem lies.

Problem Regarding Booting

due to the increase in temperature inside the cpu for the protection of the motherboard and components it might not be getting started ..

this happens if the processor fan is not running properly or if it stucked due to some dust or obstacles ...

try cleaning it after separating heat sink and processor ....

after refitting the processor trying booting it should work ....

if needed replace the processor fan ..

I really need help

There seems to be two issues here, the front switch on/off button, should turn off if you arent getting any video to the monitor, unlike when booted into windows when you have to press and hold the button in. there could be a number of reasons for the monitor not coming on, but if you cannot get into the bios (f2 or Del on boot up) the cmos chip is corrupt or faulty and require that you clear the cmos by the CLRCMOS, JBAT1 terminal, refer to your manual for the exact terminals and try re booting the pc. if you can get into the bios, go to advanced cmos settings and ensure that agp is set as primary graphics adapter if you have a graphics card, or pci, if not vga should be set as the primary controller. Also check that the motherboard is not touching/shorting on the pc casing, and that the memory that you are using is compatable with the motherboard normally signaled by one beep, proceeded by another for the graphics.
