Re: red light and monitor will not start up
You need to shut down the computer and pull the power cord off powersupply then remove the wire harness that goes on to the mother board then press the and hold the computer on button for 3 seconds then plug in the the harness back on the mother board and and plug in all power cords then try to turn on the computer it should give u a beep or the monitor should go from orange to green good luck e-mail me if u want firstname.lastname@example.org

Processors do not have monitors. Or lights for that matter. What monitor do you have and is the button you hit on the monitor or your computer tower? Are the lights on the monitor or the tower?These are important questions, don't you think?
Remove any drives and then power on, if nothing displays, replug your memory card,processor and dedicated video card if there is any. Lastly reset your bios, just remove the button shape battery and then place it back.
you posted several problems and some are resulted in your trying to diagnose the problem. IF the monitor is black yet you can see the cpu lights meaning it is reading but does not power up all the hardware. In my years of experience in solving hundreds of computer. This is primarily cause by memory or video card. Just re-install or re-insert the memory or video card. This will likely solve the problem. IF just in case the problem still exist replace the memory (RAM) or the video card to check which of which has the defect. In regards to your computer performing disk scan, this is part of windows utility to fix the hard drive. This is usually cause by pressing the reset button. This appears because when your computer does not power up you reset it. This is normal and nothing to worry about. Have a nice day in cyberworld
try this ,unplug power cord turn off computer, (if you have switch) there should be no electricity. Remove little battery that you have on your board,wait for 10 sec. and pull it back in, that will restart cmos to default values.PLug power cord, turn on computer. Post me what happened.
Check if any of the pins of the Keyborad PS2 jack. Looks loke during cleaning a few vital parts may heve moved. Unseat the RAM sticks and after cleaning insert it firmly. Check all cable and wires for snug tight connections. You could try to clean ur power switch too bt aerasol spray, but the main is the keyboard. Recheck for bent pins and/or any stuck keys on the keyboard. If evrything is OK and the PC still behves the same, try replacing the power supply (SMPS) with a properly functional one & if it works, simply buy a new SMPS and install it....sodeep
if you have changed the monitor and the same no signal have you noticed a beep sound? or can you see the green and red light in front of cpu? if both of this doesn't light it's power supply and if there are led lights (green&red) lighting but there is a continous beep sound the problem is the on board video card. if a sound short beep, beep the problem is your memory card.
Before we begin we?ll need some more historical information:
-Was this a functional computer that just stopped working or is this something you?re building?
-If this was a working computer were any new programs, hardware, drivers or updates anything that changed recently?
-Have there been any recent error messages?
