Generically, the absence of a POST screen pr beeps at boot up means that it's buggered. The CPU has to execute the ROM BIOS. If it can't, nothing can happen.

It can be anything on the...

What does "hang up" mean? We need some more precise information.

What happens if you just disconnect his ethernet cable with the PC still running?

If you get no boot data on the screen from the ROM BIOS and if you're sure there is no continued disk activity to indicate that it is booting through, then it seems to me that it can't execute the...

How's this one going, Danniboy?

If you set the DRAM frequency to a lower value, then faster capable RAM will behave itself. I was surprised to see your supplied 5-5-5 RAM operating at 400MHz DRAM frequency - but I confess not to...

There is none.

You could download and run CPU-Z from www.cpuid.com

Damn fine software. On the Memory tab, you will see the speed at which your RAM is actually running (DRAM Frequency). Below that number you...

Ah - I think I see what might be happening. The memory you've bought is 4-4-4 SPD timing and I believe your ASUS mobo needs 5-5-5 timing. I've not researched the effect differences (noting that it...

Is there possibly an ECC/Non-ECC RAM issue? i.e. the PC is non-ECC and the troublesome RAM is ECC?

Also did you try shorting the CMOS pins and let the configuration find its own POST state? ...

You're welcome. I'd go with 2 x 1GB because if one card goes down (shouldn't) you still have a respectable 1GB.

Please mark this thread as SOLVED.

As I say, I don't see how the wrong memory could fry anything in your motherboard. The CMOS idea is a reasonable long shot whic h will enable the boot process to rediscover your hardware.

The...

3 Beeps means a memory test has failed. You could go into BIOS setup (with the old memory properly installed) and see whether is an ECC memory option.

I don't see how the wrong sort of memory can...

That's fine.

On the architecture point - in my view, the architecture scope includes the software that can run. There's a good article here:
http://en.wikipedia.org/wiki/Intel_Core that...

You are very rude.

The difference in architecture is well described at Intel.com.

Obviously Core-2 Duo is the better architecture.

What do you want to use the PC for?

Also if you want to go 64 bit (all mobos these sdays are 64 bit - so I'll assume you want to use the 64 bit OS), you should consider 8GB to take advantage of 64...

The only important fact in obtaining memory is the PC2-4200 label. Go to the shop, buy the RAM with that type description and all should work OK. The rest is just confusing blurb that doesn't help...

yeah - I'd have advised you that 2nd Level cache of 6MB is about right for Vista x64.

I would always go for the Intel processor range. I trust it better since AMD is the catch-uop company that...

The reason I know it'll go as I say is that I have a DELL Latitude C640 which is a P3 Pentium with a PCMCIA slot and up to 512MB of RAM. It runs XP Pro and uses a Belkin wireless card for the...

By all means let the Windows update do the job. It'll take a long time and only if it doesn't work should you consider doing a fresh install.

For wireless, just go to a PC store and buy a Belkin...

Hi Jackie,

That's why it was on EBAY.

As to the rest of your questions, the processor is fixeed - can't change that. RAM - you should be able to put in upto 5112MB on that model.

Also try...

I hope someone will provide more detailed advice but I'll certainly help you think this through. You haven't said much about the type of encoding you do, the degree of compression you require,...

Is this related to your hotmail problem or did you solve this one and run into another?

As you know, laptops are the least fixable item, particularly when a number of factors are thrown into the...

I'd like to take up Salem's last item - virus/malware.

Before doing that, what happens if you get to hotmail via the Mail tab on MSN.com?

If you have a malware that hijacks requests to...

If your motherboard is gone there's little help we can give to get it working.

All the brainios here are advising that the mobo has gone. The key indicator is that the boot rom can't get anything...

So, what about the other stuff I've said?

On the very little you've told us, and assuming there is no POST screen display, I'd diagnose your PC as electronically dead or damaged.

You don't say very much. if your machine won't boot, how have you checked your VGA?

So, when you try and boot, what happens? Does your disk run for a minute or two? Do the keyboard lights flash...

You'd know if the machine had booted by reason of the HDD activity. It should show activity for a couple of minutes during boot and then die down.

My guess is that it isn't booting although I...

lochi,

You'll get absolutely jack sh*t nothing for your PC. i.e. £100 or less. You can get brand new stuff for £350 with a far better spec. Everybody wishes to get more than that and there's a...

So, by my reckoning:

1 Dishwasher 10 points
2 Clothes washer 5 points (jury's out on this one)
3 Oven Nul point.
4 Airing cupboard 10 points (for 12 hours)

It was dirty doh!

As long as ghe didn't put it in the damned oven .....

I suggest a common cause fault if two PCs have the same problem. Say the PCs are left on overnight - there is a power glitch and they get hosed. It might be they were in disk write mode or...

The answers to the second set of questions actually answers the first. 44C is a reasonable idling temperature for a modern CPU and 66C is a reasonable temperature for a hard working CPU that is...

I suspect that the PC was on its exit path before you bought it. A CPU can only reach 80C when not worked hard if it is not being cooled adequately (I hesitate to suggest an over-voltage but not...

No oprtions that I can see. You power up, fan comes on, blue screen with nothing more.

Take it for repair and stand there to make sure they put your data onto a USB memory stick. They would have...

loki_ is basically correct. But since your emachine is a desktop, presumably you don't have an additional external monitor to try.

You've also probably checked that the screen is properly plugged...

We need to have these in Celsius! No, just kidding. Most of the world has gone metric. Time your lot did the same.

Anyway, these temperatures are fine.

These temperatures are perfect.

... Then, just to be really sure, shove it in the oven taking extra care not to set the temperature higher than 200F (93C). If you don't have a fan oven, worry about which shelf you put it on. Not...

Blah Blah Blah. A memory stick 12 hours in the airing cupboard is fine for thoroughly drying it - a small form factor. Obviously.

"Thoroughly soaked"? 99% of the water had run off the moment...

I don't believe what I'm reading! From washing machine to oven!

Yes, dry the RAM thoroughly - an airing cupboard or near a house radiator. Say 12 hours.

Then whack it into your PC and see...
