The first thing to try is clearing the CMOS memory, either by means of a jumper located on the motherboard, or by removing the CMOS backup battery for a while. Post back if you need more information on the procedure.

What motherboard or system (if Dell, Gateway, etc.)?

Why did you do BIOS update? Did you follow all instructions for updating BIOS?

Most, but not all, boards have a facility to clear the CMOS memory. Usually it's a set of 3 pins with a jumper, it may be labelled something like CMOS_CLR, and with the power to the system off, the jumper is moved from its current position to the adjacent pair of pins for 5 seconds or so, then returned to the original position. (ie, if normal position is across pins 1 & 2, the clear setting is across pins 2 & 3). Some more recent boards have a small pushbutton mounted near the battery. But for a few boards the only way is to remove the battery for a period, occasionally this needs to be up to a period of hours.

The purpose for clearing the CMOS memory is in case either the memory contents has become corrupted during the flash process, or changed features of the updated BIOS requires more or different data and the old CMOS data is no longer correct.

If you respond to hamluis' request for system or motherboard model information, we can be more specific. Also, if clearing the CMOS has no effect, it will also help to know things like the exact flashing procedure you followed, the source and filename of the BIOS update if you updated manually so we can be sure if the correct update was used.

Also, when you say you hear the computer running, do you just hear fan and drive running noise, or do you hear a startup beep, see drive access light flashing, hear Windows startup sound? These will indicate different fault conditions, for example, if you hear the BIOS beep but get no display, maybe onboard video has become enabled and is clashing with a video card, it may be necessary to remove the video card, boot up using the onboard video, turn it off again in the BIOS setup, then shut down and refit the video card.

Did you remove the power cable when you removed the little round battery? (and if it's a laptop, you'll have to remove the big laptop battery also)
Then leave it for about 30 minutes - that'll clear the BIOS out.

Hello Platypus and usasma Yes I did remove the battery for 2 hours with it unpluged and i think I found that jumped and I did whiched it around for about 5 sec. I guess this is a old computer? It says on the front vpr Matrix motherboard says ( Intel Desktop Board D845BG ) and it does not have no on board video. I did put another video card in it that i know that works and still nothing. When I plug in the tower it starts up by it self and yes the CD drives light up and the hard drive is running also. The monitor looks like it is going to come on then it goes to sleep when I turn off monitor and turn back on it does the same thing goes to sleep ?

Which VPR Matrix model do you have? How did you source the BIOS update, from Intel? Was it the one here:

http://downloadcenter.intel.com/filter_res...mp;submit=Go%21

If so this may be the correct update, but often manufacturers like VPR use a custom BIOS version to match their own customization of a board. Then using a standard BIOS update from the board manufacturer can cause failure to boot. So we still need to know more information about just what you did. Do you hear the single BIOS beep, Windows startup sound?

If the BIOS flash went bad, clearing the CMOS is not going to help
