Hopefully some of you may have had this problem before and can share your experience with me. I have a Desktop Gateway computer which is about 7 1/2 years old. I have windows XP with SP3. At certain times, not very often, when I push in on the switch to start the computer it tries to come on as the red and green will come on and stay on. It sounds very loud as if every fan in the computer is staying on. It will continue doing this until I pull the power cord from the computer. I cannot shut it off by holding in the switch. When I try to hold the switch in, to turn it off, it will turn off momentarily and then the power kicks right back on. It will continue to do, turn on, turn off, as long as I hold the switch in. Even when I release the switch it will not shut off. When this happens my only recourse is to pull the power plug. Due to the age of this computer I am not going to buy anything very expensive, nor will I spend a lot of time to fix it. I am making this post in case it has happened to some one else in the past who can give me specific actions they have taken to fix the problem. I know some of you old timers on here may be able to give me some good advice on this. I do not have any special tools to check any of the equipment on the computer. Hopefully it will be something simple causing this. By the way, it is hard for me to explain the way the computer is acting. If I have confused anyone, please let me know and I will try again.

it's probably failing power supply

The simple way would be replace it the whole computer or Power supply However dust and dirt can make contact with the switch or the conductors on the motherboard not contact with one another.

I suggest to blow out your computer first with air compressor or can of air from your local hard ware store. If you use an air compressor (I do this all the time. I volunteer at a school) please take it outside and set it on something and open the case and blow it out.

If blowing out helps that great if not than it more liking your PSU is failing

coxchris, you may be right. This would be a good idea. It is hard to isolate something like this since it happens so infrequently. I will definately try blowing out the air before I buy a new psu. I have two laptop computers besides this desktop so it is not like I won't have a computer if something happens to this one. Thanks for your suggestions. I appreciate it.

Your Welcome its know to happen with Power supply that old and in there nature hard to troubleshoot because there no way to pinpoint without buying a PSU tester or a miltimeter. Over time A power supply losses it power or diminishing due to wear or natural causes.
