One day i left the computer plugged for the whole day. when i came back i plugged it out. then i tried to turn on again the pc but it freeze when the windows xp logo came out. then i restart it then freeze when it's doing the memory scanning. after that whenever i turn it on only the YELLOW light in front of the casing only lights up and nothing else happens no boot sound whatsoever.
by the way the ram and harddrive were ok. and i have a new power supply unit. the video card was not ok. the processor and motherboard i was unable to check. i unplugged every connection inside, i even unseat the motherboard from the casing, and tried to put back things in except for the video card since there is an onboard vidcard.
this time it's the RED light turns on and still nothing happens. my motherboard is ASUS P4VP-MX and my processor is a 2.4ghz p4. hope you guys can answer my problem. thanks!

If you are having just a blingking cursor on boot up you must check if there is a disc inside the disc tray, or kindly check as well if there is a USB flash drive plug in on your computer and if there is any please remove them while your computer boots up as your computer might boot from it and it may cause just blingking cursor.
If there is no disc or USB flash drive installed, what you can try is to boot your computer in safemode and perform a system restore. Atleast restore back your computer 2 to 3 days back before this problem happen.
To perform safemode:
- turn off computer
- press the power the botton and after 2 sec tap F8 repeteadly until you see all the safemode options
- select safemode with networking/safemode use the arrow keys to highlight it then press enter
- computer will automatically boot into safemode desktop.
To perform system restore:
- click start > all programs > accessories > system tools > system restore
- click next then select desired date then follow the on screen instructions
- once system restore is done it will automatically restart and boot your computer in normal mode.
check your power cord to insure that you are getting power. make sure power cord is plug in the back.
look in back of computer. you will see a little orange switch. it says 115/220 click to 220. boot computer.
if computer boots up turn off and click back over to 115.
if it does not boot your power supply in your computer needs replacement.
The Power Buttons
electrical circle sometimes just braked it by one of sensors and the
result is the 2 beeps and Power Supply is in protected mode error.
whole computer is turn off but the power button is turn on and this is
the nub of the matter. Because if you want turn on the computer you
can't because already turn on but just the Power button and you can't
The solution: You need just change the Power
Supply and don't do anything just the power cable put into the Power
Supply after turn off computer. Finaly change back the Power Supply.
if the monitor works fine on your laptop, the problem definitely is at the computer, possibly with the video card (if it is using one). it could have loose connection, or parts might have damages. it seems the problem is intermittent so electronic component of the video card could have parts partially damages or leaky components. if your still using the motherboards built in video out put, try installing a new video card.
First remove the battery from the PC! Leave it off for a short period of time! about 2min. This allows the computer to erase anything in temporary memory. Place the battery back onto th PC and try to boot it up. The other thing you can do is boot the pc up with just the power cord in place. See if it boots just from the power cord. Sometime the batteries from dell causes the whole entire PC to become unresponsive.
