Power Supply I just purchased a compaq presario 6000 desktop on ebay and i think something must have been dislodged during shipping because when i try to turn it on, it comes on very briefly but then goes back off and a red LED light in front begins to blink. Ive opened it up but i dont know what to look for. Any ideas?

This problem occured for me. The Presario 6000's Power Supply has a small two prong power connector that hooks to the motherboard. Without this plugged up I found that the CPU fan wouldn't work and the CPU overheated causing the PC to cut off. So if this is of any help, look to see if there is a two prong power connector on your power supply and if so, plug it into the two prong connection slot and see if this helps your problem.

Good Luck! Jeremy

We had the same problem with our Presario 6000 when it was fresh from the box - within the first week. After haggling with Compaq they exchanged for a new one, but soon after replacement we had the problem arise again intermittently. We tried troubleshooting it for several years to no avail.
Eventually we broke down and took it to our very trusted tech repair man said that the power supply was a POS and replaced it with another -completely autonomous - power supply and it has been fine since. Good luck!

If the processor is installed. It sounds like the CPU is overheating. Remove the heatsink and put new thermal compound on and reinstall Processor

I have the same problem. I even opened the power supply where I think the problem may be. Before I start to measure electronic components I will try to vacuum clean it all: sockets, components with care. In my case the computer was working and suddently it shut-down with no warning or error messages. Simply went off. If you have news about this log here. Today I will try to make it work. You spoke about a shipment: that gives me one idea: it may be broken solding points. With an hot solding iron try to rectify (with care and after all capacitors in the power supply are discharged to avoid electric shock) those soldures. Best regards, Daniel.

I would to make sure all the power plugs on the inside of your computer are snuggly secured. Also check to make sure the RAM sticks are plugged in correctly and that the processor is present and in place.

Presario won't power up

If you see no lights, hear no fans running, no disk drives running then the problem is probably a bad power supply or motherboard. Get a quote from your local computer shop then try the guys at:

They will fix it and ship it back by Fedex or UPS. They are very economical and good.

If it is the fan in the power supply, replace the power supply.
The case fan is easily replaced. Measure it (in mm) and purchase a new one. The standard fan is usually 40 mm, I think.

I think it was hit by a surge during a thunderstorm.

In that case, I would suspect that the power supply has failed. Do you know if the computer was on during the surge? If not, then probably only the power supply is bad. If the system was on, then ..... could be damage to other parts.

Power supply is easy to replace. In most cases you only have to remove 4 screws from the back of the computer. Then of course there are anywhere from a few to many connectors from the power supply to the components in the computer. Each connector is unique so.... you will not be able to plug the wrong connectors together.

You can also buy a small power supply tester if you want. It will allow you to run a rudimentary test of the power supply checking all the voltages for the motherboard, drives, etc. Here is an example,
$12 dollars including shipping. You may be able to find a better price and brand, do you own checking before you buy.

Tower compaq presario 6000 will not power up

after reading your query i can understand that there may be no issue with the power supply,
can u hear any kind of long beep? if yes try cleaning the ram, if this also doesnt help then try changing the ram.
if this is not helpful please check the cmos battery,
if battery is ok, then there may be a problem with your motherboard of Processor.

No Power!!

Double check the switch in the back of the pc on the power supply. If their is a switch, you can try it in both positions. It is possible their is no switch, older compaq's are iffy. The switch will be black. Also check the 110/230 switch. I don't know what country you live in, however you may need to make sure that switch is in the appropriate spot. 110 for USA and 220/230 for UK

Also, try unplugging your pc. Let it set for about 1 minute. Plug it back in and try again.
