So i checked if any capacitors were leaking but i see nothing leaking , i checked the cpu if it had a burned part around were the paste is but nothing , the only thing i saw was when i took the cpu out one of the pins was a little bent so i fixed it it and now the pin is ok so i tried booting everything up again and still have the same problem i only see a blank screen i took the ram out and try booting up without any ram but nothing used a diffrent scrren but nothing can the graphic card be bad or what? and is it possible that the bent pin could of done something?
Well your trouble shooting is fine, but you have to do it step by step to determine the actual problem. Now you can do it again the process. 1. I assume you have your mobo out of casing. Remove your RAM. Plug in your power cable and turn on the mobo. At this point you should hear beep sound. If the sound is heard then your mobo detecting that the RAM isn't exist, which show a good sign that the mobo is still functioning. 2. Now place back your RAM but taking out your graphic card. Turn on your mobo, this time you should hear a long beep sound. Again if there is beep sound then your mobo is still functioning. Now if you can not hear any beep sound on either steps above probably your CPU or mobo is defected. If you can hear the beep sound then you could try many more steps. You can put back the graphic card and plug your monitor to it. Do not connect to hard disk yet because it could damage it during the test. You could start by clearing your CMOS, then replacing the RAM and the graphic card. Well you try first and give us your feedback. Good Luck.

So there is not so much as a BIOS message on screen? Any beeps? If there is no life at all, you have a CPU/motherboard failure. This may be direct or indirect (e.g. no power to MoBo). Check your connections. Otherwise, your boot device may not be operating. This is usually a dead or disconnected HDD. Check that it is plugged in. Does it get warm? Can you feel any vibrations from it? It should spin even if your cpu is dead but MoBo is alive.
Remove the battery and open the case. Look inside the computer with a flashlight to see if any of the capacitors are busted or leaking from corrosion. The capacitors look like little battery towers, but they are not as tall as the AA or AAA batteries.
If the capacitors are bad, your computer goes bunkers.
This laptop is fairly easy to check for overheating causes. Remove the large cover from the back of the laptop to reveal the CPU and heatsink fan. Clean the area around the fan and heatsink. Power the laptop on and see if the fan moves ( also see that the 3 pin connector that connects the fan to the motherboard is plugged in).
Check for blown capacitors, burning around the components and signs of overheating on the board area that you can see. You could try replacing the CPU chip in case it has burned out, however, I rather suspect that the overheating has damaged another component on the motherboard and a replacement motherboard is required
Sounds like a capacitor has blown on the motherboard, but before condemning it, check the following: 1.) Does the CPU fan turn and does the heatsink get warm after a few minutes? (This indicates that power is at least getting to the CPU 2.) Check connections of ALL the main power connectors (ie: the 20/24 pin plug to the mainboard and the smaller 4 pin plug to the mainboard. (If not firmly inserted will stop the board from firing up) 3.) Check the graphics card is firmly seated and test with anew graphics card to eliminate the issue being with the graphics card / check tightness of the VGA cable to monitor and card 4.) Remove all but the main power and 4 pin power plugs and try rebooting to eliminate hard drive or DVD drive failure 5.) Remove and replace each ram module in turn try booting in between 6.) If you have a spare PSU, replace the existing one and test the board using that, sometimes the PSU appears to work, but lacks power to fire up the board.
After all that, you are down to the mobo or CPU, you can try a new CPU, but I feel that the issue is with a blown capacitor or a burned circuit trace, only close inspection of the mobo will reveal bulging, leaking or blown capacitiors (small cylinder like things on the motherboard)
Hi A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed. This will cure the problem as they overheat being sat next to a heatsink that gets very hot! Try and change them for the same 3300uf but a higher voltage. Hope this helps
I assume you have had the side panel off to watch the cpu fan spin up? if it does spin up and you get no bios beeps, then the fault is with the motherboard or CPU, most probably the motherboard. Problem sounds like capacitors blown or leaking ( have a look at the board and see if any are bulging or leaking). I've had similar issues with the motherboards that HP use, in all cases it was the motherboard at fault
try to remove the motherboard from the casing and see it if the have
some capacitors or any circuit distroy. use other mother board for
testing chek your hardware one by one maybe some of your hardware
Hi this is
the way how to examine what's wrong with your LCD monitors. Power on both CPU
and monitor. After it went blank, you have to check that you can see the
image on the screen by shining a flashlight into the screen, not directly but
find the best angle to the screen and take a look very closely. If you can see
the icons or any image, there will be a minor problem. Like mine, I can see
window image using flashlight and check lamps inside. Some of them were broken
and it is very easy to replace. If you cannot see anything on the screen, there'll
be some problems with inverter board. If you have soldering tool and want to
fix it by yourself, check the caps first. It may cause this problem. Some caps
might show leaking or burn spot on the board because of too high temp. If you
don't have soldering tool, you better go get a technician to do so. Thank you, Tan
1.low supply of voltage try checking your Power Supply Unit(PSU). try to swap with a different good PSU.
2.Defective/burned Motherboard, check for any bloated Capacitors or burned chips...
