geek sqouad told me that it might be a power light
Power "
light" or power "
supply"?
(if you are comfortable about opening up your PC)
I gotta speak up here - If anyone is
uncomfortable about opening up their PCs, to be blunt, get over it! Or find someone who is not because it is a user/owner responsibility to periodically inspect, and
thoroughly clean, when necessary, the interior of the computer case! No ifs, ands, or buts! Unless you are using alternative cooling (and you would know that if you did), your computer mostly likely has at least one case fan and the PSU fan drawing cool air into the case - and unless you work in a genuine "
clean room", they are also drawing in dirt, hair, dander, tiny critters that eat dander and all the "stuff" those critters leave behind too!
Computers located on or near the floor, in high traffic areas, and/or in the same environment with pets have it worst. Look at your desk - that is dust that just
fell there - now imagine months of that being sucked inside your computer.
Heat is the bane of all electronics. This dust, if left unchecked,
will create a heat trapping blanket - everywhere. If it has been more than a couple months since you have opened up your computers, then I recommend you shutdown Windows, power off your computers,
UNPLUG your computers from the wall, then remove the side panel and take a look. Touch bare metal before reaching inside, and frequently thereafter to discharge any "
difference in potential" between you and the case from static electricity in your body - the ESD precautions as seen in the link John post. Inspect the CPU fan, heatsinks, case fans, chipset fan (if present) and video card fan (if present). Give them a flick and make sure they spin freely. If the case, or any of the heatsinks, boards/cards, fans, or vents are full of dust, they need to be cleaned. I recommend compressed air. Just take it outside first - it's counterproductive to blast it back into the room only to be sucked back inside the case again. Before closing up, touch bare metal, then press on every power and data cable connection to ensure they are secure. Route cables as much as possible to ensure the best front to back air flow.
It really is not hard. The hardest part is computers can get heavy. Some new cases come with washable filters. My wife's Antec Sonata has a filter, my older Antec tower does not - same room and I have to clean my interior 3 - 4 times more often. I will never buy a case without a filter again.
You can buy cans of compressed air at your local Walmart, Radio Shack, or home improvement store. Using a vacuum is generally not recommended. However, it can be done safely if specific precautions are followed. I have a canned text that includes a safe method for vacuuming. If anyone would like to see it, I can post it.
Laptops need cleaning too, and the user can do some limited cleaning by removing all plug-ins and opening all access covers, and blast with canned air.
And finally, not to drag this thread too far off track, but here's why I recommend all computers be on an UPS. Depending on your power needs, you can generally get a very nice uninterruptible power supply, with AVR (automatic voltage regulation), big enough to protect your PC, all your network/Internet hardware, and one or two LCD Monitors for under $130US. Note that battery backup is only the icing on the cake with an UPS with AVR, but it would have come in handy this time.
Do you have a current backup?
thanks for the help it help me solve the problem i went to the hp site and tryed all the steps accapt taking the case off etc so when that didn't work me and my mom called few tech places in our local area found a good one they said to take the power block off and take it to them they would test it for free and let me know if its missed up well it was so we talk to another dude about it we buy the part needed get home install it and got it to work its running smooth thanks for helping glad i didnt pay the 50 bucks couse the part was 31 bucks and if they gave me some of the hp steps that was on the link john hook linked me to then that would have been a waste of money when i could got that info for free and had money for my part
