Please help, computer not booting after....

Uh oh.....

How long was the computer off before you cleaned it?
What kind of towel???? (I've never heard of using a towel to clean a computer)
Did you use a compressed air can too?

As for the towel, I personally wouldn't use anything to clean a computer that actually touches the components because they could introduce static electricity. I suggest a compressed air can. However, I have a friend who once cleaned his computer with an air can and it fried his motherboard. Why you ask? Air cans put out some pretty cold air. The temperature difference of his still hot computer and the cold air broke something. This could be the scenario. (I hope not)

You could also have a problem with your power supply or a ram stick. Try booting the computer with only one ram stick, and see if this helps. If so, the other ram stick is bad. I would also suggest trying another power supply if this is possible.

Before you do any of this, try to reseat the ATX connector. Also make sure the 12v power 4 pin connector is connected, along with the power connector to the video card. (Does a 5200 need one???)

Best of Luck

Thanks for your reply. The computer was off all night, and I use the towel to clean the outside of the case and the case fan only, I didn't use a compress air can, I just blew it with my mouth, also I forgot to mention that I changed my old dvd-rw drive for another one. I already try to boot it with one stick of ram but no luck, will reset the atx connector and see what happens.
Thanks.

Try re-seating the RAM. Take the sticks completely out, and then put them back in.

Any luck?

If not I would try the CMOS reset jumper. This should be on the motherboard somewhere near the BIOS chip. (Usually the lower right of an ATX motherboard) Turn off the computer, then switch the position to the opposite position. Count to five then put the jumper back in the original position. Power on the computer. Does it POST?

If it didn't, I would try disconnecting EVERYTHING but your graphics card (and monitor), processor, and one stick of ram. Disconnect all of the drives and all cards. If this will POST, then you can start putting things back in, one at a time.

If this doesn't work, you have a major problem and some piece of hardware has fried...

Best of Luck

run a humdifer so u do not get static

buy a can of air and use a vacuum to clean it - first vacuum the loose stuff then blow out the heat sinks and little areas then vacuum again.

since u disconcected the drive look for drive in the bios,


------------------------
your problems is left something unplugged it sounds like - power to video card maybe. or something is stuck

did u reverse a cable or psu connector?

try resetting video card and ram stick(s)

Thanks guys for your help. I solved the problem   , unplugged everything and plug it back on, and it worked. Thanks.

Good to hear. Probably dislodged a little particle that was causing a minor short.
