Your computers motherboard is limited to 128 sticks being the largest size it can recognize. You could have it work with 4 128 sticks to get 512, but a 256 stick will not work.

Did you build your computer yourself or was it a store bought branded computer?

This maybe caused by many things.

If you had a ram problem run a program called memtest86. Located here: http://www.memtest86.com/memtest86-3.2.iso.zip

However, i do not think this is why your...

Was this in a brand computer such as hp, dell, etc...or was it a build you or someone else did.

Nope that sounds perfect. You really cant get faster than that. Just make sure you use dual channel memory and you should be set :)

DDR2 Ram isnt that much faster, if any at all. It may appear so because they have "faster clock rates", but the fact that most DDR2 ram has such high latencies, they about equal out with DDR ram with...

Ok...that was with one piece of software. How about several different programs now for a more accurate comparison?

yes, my dell is fn f2. Also, check and make sure wireless in enabled in your bios. Check along the sides of the case for a switch though also, some have the switch too.

Do you know the model of your computer?

i would never change this if i were you. Something goes wrong and you need a new motherboard. Even a bad windows boot screen can cause your computer not to boot...

Many laptops do not support programs such as motherboard monitor to measure the temperatures of its components. However, if you can feel that it is too hot to the touch, you could invest in something...

Just because your computer is using 60% of its memory doesnt mean its going to die. It just means your computer could use some more memory. You could try upgrading to 1 gb (2-512mb sticks), and you...

I just thought i would throw in my 2 cents as usual... A great program that tells you information about your computer is called cpuz. You can download it (free) from here...

Are you sure your laptop supports upto 256 mb ram? something tells me 64 at most, but possibly 128... Did you read that online somewhere?

server boards are really picky about ram. it is best to keep all the same brand and size chips with in the board. i would never mix and match brands in there either.

Scrap that processor, get the single core 3.0 ghz lga 775 processor (about $180) and get a minimum of 1 gig ram. I promise you that you will have a faster machine for most uses if you have 1 gb ram...

That sounds much more acceptable. I have the 3.2 ghz version and it runs around the same temps at idle. (46-52*C).

Remember that with thermal paste, just a paper thin layer is required, any more...

woa! if that is true stop using it immediatly! the thermal threshold of that processor is 69*. Are you sure that is celcius it is reading in? If it is, make sure your fan is spinning up to speed and...

If you want to be 100% sure, download CPUZ from the attachment i put below, and in there it will tell you what kind of memory you have currently. Report back as to what it says, and I will let you...

You are talking a difference between SDRAM and DDRRAM. All SDRAM is single channel, but some DDRRAM is single channel, while other is dual channel. If he has single channel DDRRAM, it will work in a...

If you have single channel memory right now, and you get a duel channel board, your new board will recognize your configuration automatically and put your rig to single channel memory.

However, i...

Maybe they werent properly installed.

Some motherboards will not support that processor. I have the same chip and ran into the same problem even though my motherboard specifically said it would support it. I solved my problem by getting...

You can't just "add" a video card slot. They come built onto your motherboard. What you will have to do, is buy a new motherboard, and likely a new computer case, and you will need to reinstall your...

so i am guessing you didnt install a graphics card, you are just using the integrated graphics. did you try and insert a graphics card to see if you could get it to post video?

Also, did you try a...

did you install a graphics card? if so, is the monitor plugged into the graphics card or the integrated graphics of the motherboard?

Ok, 3.0 -> 2.5 will give you about 1-5% max difference, but you will sacrifice possible system instability which in my opinion is not good. Yes, you can overclock on air, but you will need better ram...

I use motherboard monitor also. It is pretty good. you can download it free here: http://www.softpedia.com/get/System/System-Info/Motherboard-Monitor.shtml

some motherboards are picky, but this is rare. typically it really wont matter what brand like goldeagle said. However, i would remove the origional stick and put the new one in the old sticks slot,...

I had an asus board that origionally had a northwood processor in it, but the board specifically stated on the web that it would support a prescot upto 3.4 ghz...i bout a 3.2 pressie and it wouldnt...

Well, i think 2 gbs is the max one would want to go. I recently upgraded mine from one gig to 2 gig and the performance is no different under normal usage, but i do notice that under multiple huge...

Pull out all un necessary components that are not required for the computer to turn on (ie pci cards, floppy disks, hard drive, rom drives, etc). Then Pull off the processor heatsink, and take off...

Ram is a physical stick that contains memory modules on the circuit board. You just push it in an empty slot when the comptuter is turned off. But there are different kinds of ram. Please tell us the...

Well, you cant just change the slot. I believe you would need a new motherboard. I love dell, but they charge way too much for replacement parts. If after cleaning the slot with some pressurized air...

I think you can upgrade to around 850-900 mhz amd athalon with that board (dont quote me on that because i havent found any crediable site that directly states this), but i think you will have a hard...

your motherboard determins what processors your computer can handle. Photoshop is a pretty demanding piece of software requiring lots of ram and a fast processor to do anything efficently. It may be...

Which cables did you plug in already? does your computer have usb ports on the front, and audio too?

WHat it sounds like though is the two power ones should be pluged into the power part of the...

What case did you buy?

As every motherboard is seamingly different in this regard, consult your motherboard's manual. Theyalmost always will give you this information.

And for the other part of your request to reset the bios back to factory state, upon boot, hit f2 or del a few times before the windows logon screen and there will be an option to reset back to...
