I think i kill my son system

[Gamemaster]

Ok working on my son dell 8300 get a motherboard for the system he told me it was bad ok putting it in was ok the CPU was ok now i put to much Silver Thermal compound on the CPU ok now starting the system was ok only thing it was not working telling me to restart the system did this 10 times and was thinking it was not the motherboard it was the CPU so i took it off and had one that i know was working ok here the part i mess up i got Silver Thermal compound on the CPU thing that hold it to the motherboard and now it will not boot up at all this mean i have to get a new motherboard and CPU now any help thanks ken:cheers:

- Apply thermal compound on the CPU as per the instructions here (http://www.arcticsilver.com/arctic_silver_instructions.htm). (Assume you're using Arctic Silver 5)

- Mount the heat sink and fan then connect the fan to the fan power header on the mobo.

- Do not connect the PSU to the wall outlet. Do a Clear CMOS by placing the CMOS jumper on the Clear CMOS position for about 10 secs.

- Put the CMOS jumper back on the Normal position then connect the PSU to the wall outlet.

- Power up the PC. Go to the BIOS to reset the settings.

Do a Clear CMOS by placing the CMOS jumper on the Clear CMOS position for about 10 secs.--ok how do you do this i am not a pc guy ): thanks ken

Next to the battery socket you'll see a 3-pin jumper block. The CMOS jumper should be on the Normal position now (pins 1 and 2). Please remove the jumper then place it on pins 2 and 3 for ~ 10secs to clear the CMOS. After that, put the jumper back on pins 1 and 2.

This page (http://support.gateway.com/s/Servers/COMPO/MOTHERBD/m00404/m0040414.shtml) has a good example.

If you got silver compound on the motherboard, you most likely fried it.

ok did not work when you start it up the hard drive make some sound now i did put the old motherboard back in too same thing you think the ram got fried. i have 3 video cards too not one of them would show me the screen so it only start up no video :(

someone send me this
Because thermal grease's thermal conductivity is poorer than the metals they couple, it is important to use no more than is necessary to exclude air gaps. Excess grease separating the metal surfaces further will only degrade conductivity, increasing the chances of overheating. It should also be noted that silver-based thermal grease can also be slightly electrically conductive. If excess were to flow onto the circuits, it could cause a short circuit.

The preferred way to remove typical silicone oil-based thermal grease from a component or heat sink is by using Isopropyl alcohol, or pure acetone is also a valid method of removal.

Did you Clear CMOS? When you install the mobo to the case, make sure the bottom of the mobo does not touch anything but the stand-off's for the screws. Recheck the 20 or 24pin ATX power connector and make sure it's firmly connected to the socket. If your mobo has a 4pin or 8pin ATX 12V header, make sure you connect the 4/8 pin power connector from the PSU to it or the system can't boot.

No not on motherboard i got it were the CPU go on the holes and it still and some is still in the holes i hard to clean it off i just order a new CPU off e-bay going to get a new motherboard it start up before i took the cpu out and put a other cpu in it must be silver compound still on the holes if the motherboard is bad the system will not start and the jumper i did the pass word one not the CMOS one did not know there were 2 of them on the motherboard just look on dell going to see if it will do anything now i mess this one up real good :(

[Van Nugent]

I didn't expect you had put the paste on the socket. You might not have damaged the mobo but some of the pin holes might get insulated real good due to the paste getting into the holes. The CMOS jumper is next to the battery socket. It might not do any good, though.

[Van Nugent]

If you're not sure about the jumper, removing the CMOS battery while disconnecting the PSU from AC will also clear the CMOS. When you put the battery back into the socket, pay attention to the polarity and make sure it's correct (+ and -).

Edit: Isopropyl Alcohol (90%) is very effective for removing the thermal paste. Disconnect the AC before attempting to clean the socket with IPA.

Ok the dell 8300 motherboard is not work 2 cpu are not working now i put in the dell 4400 motherboard back in and the same thing on this motherboard and it was working 1005 before i put the dell 8300 motherboard in the 2 case were the same and the 4400 case look new. you think paste got in this socket too the cpu ahd some on the pins

I didn't expect you had put the paste on the socket---only i can do this :(

now looking on e-bay for a motherboard and cpu i did put 2 power uint to see if that was and no so i kill 2 motherboard the 4400 motherboard look great paste must of get in there too i thank you Van Nugent for all your help next time i will post before i do anything on a pc looking at the 2 cpu there was not paste on them just a pink paper thing that the cpu was on wish i seen that in the stores again thanks Van Nugent for your help let you know how the new motherboard and cpu do and i had 3 video cards too so i know thay work

[Van Nugent]

I'll be glad to work with you on your new system. Please check the Arctic Silver link in my post #2 for the instructions to apply the paste correctly.

ok up-date the new CPU came in system is working 100% now so it was the CPU not the motherboard so happy on that i did get a new system set-up will post on this one thanks again :cheers:
