Power problems with Dell Dimension 4600

My computer is not starting up at all. After some online research I discovered this model has had problems with faulty power supplies. So I replaced the 250 W with a 450 W. Still the same response, nothing except the flea power light on the mother board. Not even the fan on the new power supply is running nor the CPU fan. Different configurations of wiring from the power supply have all yielded the same results. The capacitors all look fine, no leaks or bulges. One thing though is that the paste/glue holding down the heat sink has deteriorated so that the heat sink is no longer seated and comes off. Would this affect start up power? Would replacing the paste make a difference? Do I have a bad CPU or motherboard?

The power supply was bad... Put a new one in and it started fine. I tested all connections first.

I may have a soulution for your problem I have seen this happen before, If you have an external video card Unplug it from the mother board and try to reboot system ,should reboot fine, unless you are have some other problems and don't have an external video card but I have seen this before. You said that the mother board light is on and green My opinion is that it may be the problem if you don't have and external video card let me know I can get you a new mother board for that computer.. Thanks Hope that gets you going . If its the mother board. I sure hopes its not but it can be fixed alot cheaper than a new computer

Hello !!!

Normally Dimension 4600 models can be resolved just by doing the power drain. All you need to do is unplug all the cables behind the tower. Press & hold the power button for 1 minute. Now turn on the PC, it will work. If still the same kindly check the back LED's and let me know the status.

The two biggest culprits would be:

the power supply and the motherboard.

I'd start with the power supply since it's cheap and easy to install.

Find a local computer shop that sells 'em.

Make sure they've got a 100% return policy.

Swap 'em, if it works problem solved.

If not it's probably the motherboard. You could always have a local tech check it out.

Make sure they provide FREE diagnostics. It shouldn't cost you anything to have ti looked at.
