You mention an eMachines monitor, is the main computer bit an eMachines as well? Because unfortunately eMachines systems tend to only have a life span of somewhere between 18 and 36 months before the power supply malfunctions and cooks the board. So you usually end up replacing the board and the PSU together and repairing (or in extreme cases wiping) the Windows on it.

If its in warranty then send it for repair.

A typical solution to the common eMachines problem is to buy a new motherboard for your processor and also a new power supply. Normally the processor survives but the motherboard is well and truly toasted.

Even the dirt cheap budget PSUs and motherboards are way better than the eMachines hardware you have now. so even the cheapest options will make for a far better system performance wise. Not that I recommend you skimp on the PSU seeing as its an important part of the computer. What you replace the toasted bits with depends on what you do with the computer.

The scary thing about eMachines is that they're owned by Gateway who is itself owned by Acer, both reputable companies that sell decent machines under their own names yet continue to actively push eMachines branded systems out with power supplies that'll kill the machine in less than three years time.

A lot of the eMachines I've seen tend to use processors with the slowest FSB going at the lower end of the scale. It usually means you can drop it into any board going and it'll recognise it straight off. Realistically all you need is a board with the same socket type and you may be able to reuse the heatsink and fan.

As to the PSU - most of the times I've seen eMachines stick 250w in them. 250w is literally borderline for what eMachines put in the machines as standard. Add anything else and it'll put more strain on the PSU only causing it to fail a lot sooner. Look for at least 400w and it'll give you peace of mind you can actually add something without running the risk of overloading the power supply.

awesome lol so a fairly cheap fix. I went home last night after a 15 hour day at work and decided to fiddle with my computer a little praying that i could get it to work some how. i went back through switching out each stick of ram between each slot with no luck. For whatever reason I decided what the heck ill try and pull the cmos battery and move the jumper over. Well the battery removal didnt do anything, but when I moved the jumper over and powered on suprisingly the fans kicked on and the back off and no beeps. Computer went straight into the bios where i immediatly changed everything back to default. I have started and restarted the computer 7 or 8 times since then with no problems thankfully. its even running better with the new ram. I may go ahead and change the psu and the mobo just for the heck of it so i can get more ram and i dont have to worry about the psu goin out in the near future. any suggestions on what to get tho?

Hi there,

If the system is running fine, then there's no point changing the motherboard just yet... But as Neil has mentioned, I would definitely change that PSU!

With a high-quality PSU providing clean, stable power to the system, it might last a good while longer than you think.

This Antec Earthwatts unit is a nice, efficient unit for the price. If you are able to make use of the rebates, you'll get it very cheap! I have an Antec PSU myself, they are a good choice, and definitely would be a worthy upgrade in your situation.

Cheers

Troy
