I have desktop computer with celeron processor CPU 240 GHz and 512 MB ram with 40 GB HArd disk.. I see my hard disk encountered some problem and planning to by new hard disk ..which is best for me and the...

Hi ,
I assume you are under Windows XP but this will also work under Windows 7 32 bit .
You can insert a 100GB HDD without any problem . A higher capacity is risky with your type of machine and could lead to a fatal read error , meaning you couldn't boot your unit anymore .
Under a 32 bit XP system , 2GB ram is the max.
I don't recommend changing the processor with the motherboard , you could encounter conflictual issues with the rest of the unit .
Buy yourself a new pc equiped with a I5 or better with a I7 processor running under W 7 64-bit is the solution but they still are expensive .
Best regards .

Cannot delete or save any file in 512MB pqi ? How can I solve it? what are the procedure ?

Does the device have a physical switch (or slider) to block all "write" attempts (to add a file, or to update the table-of-contents to indicate that a file has been deleted) ?

If not, then copy all the files onto your 'C:' disk-drive, and burn them to one CD-writable disk.

Then, take a hammer to crush the flash-drive, to prevent anybody else from pulling any files off it.

Then, spend $10 to buy a new 2048MB (2GB) flash-drive, i.e., 4 times as much capacity.

Dimension 8200 PC Desktop: my computer is slow and it says the virtual memory...

There are many reasons why a computer may lag in performance. You may not have enough computing resources to handle your current computing tasks. Each year, software vendors add new enhancements and security updates to their software packages. The more robust a software package becomes, the more resources (i.e., RAM, and hard drive space) it consumes. So, even with a perfectly healthy computer over time the performance may lag due to increasing computing workloads with no change in key hardware components.

My company builds custom computing systems. I tell all of my customers that the single most computing resource, in my opinion, is RAM. I always encourage them to buy at least 2GB of RAM.

Hard drive space is also very important. As you begin to fill your hard drive up with files and applications, performance may also drop due to a phenomenon called virtual memory.

So, here are my recommendations:

1. Add more RAM to your system. If you're running 512MB or 1GB of RAM, upgrade to at least 2GB. If your motherboard will accomodate 4GB, you should upgrade to 4GB. RAM is very inexpensive these days. Retails prices are roughly $50-$60 per gig. Maybe lower depening on where you source it.

2. If your hard drive is more than 85% of capacity, you should remove unused programs and files. If all these programs/files are critical, I suggest having a local IT provider install a second hard in your desktop chassis.

3. Windows hard drive properties - One of the easiest ways to boost performance of your PC is to use some of the included Windows utilities. If you right click on you "C" drive, you will see multiple tabs. on the "General" tab, you should do a "Disk Cleanup". The disk cleanup is an automated tool that shows you items on your computer that could safely be removed. After doing the "Disk Cleanup", go to the "Tools" tab. Run a "Defragment". After the defragment, you should check your hard drives for errors by clicking the "Check Now" button. The error checking will require you to immediately reboot your computer before the error checking will start. Once your computer comes back into error checking mode, it takes a long time. Roughly, it will take 45 minutes to an hour. When I have customers that have some program working improperly, this is the first thing I run and it has a pretty high success rate.

4. This last option should be done in lieu of number 3 if you have some time on your hands. Backup up all your data and reinstall everything on your hard drive. Most manufacturers have recovery tools built into your system. Or they supply you with recovery DVDs. Its a lot of work installing everything again, but your machine will run like new.

5. There are many 3rd party tools that claim to optimize your PC, but I don't have any first-hand experience to give a recommendation.

Adding RAM causes PXE-e61

Most likely you have a slow or dieing hard drive that is why when as you state you add correct ram upgrade the unit fails to boot.

skip the ram and replace your hard drive with a new ssd (solid state drive)

I want to upgrade my lenovo laptop ram memory from 1gb to 2gb by adding one more stick. i currently have ddr2 PC2-5300(333MHz) latency 5 5 5 15 2T RAM my friends advised me that BLUE SCREEN ERROR occurs...

The rule of thumb with RAM is to always buy matching pairs. So instead of buying one new stick of 1gb its a better idea to buy two of the same kind and replace the one that is currently in there.

Before you even think about doing this, head over to lenovo's website and make sure that the computer is compatible with 2gb(from the speed of the ram im assuming that it will, I don't know of many DDR2 computers that cant have 2gb.) you may also be able to get ram that is faster if it is compatible, The website will have all this info.

My second not show in my computer

It is a desktop unit I supposed? Hello, first of all do you change your motherboard with the same type? If not, and you used the same hard drive with the software installed intact. There will be software configuration conflict, since it is a different mobo, different chipset and different driver to run it. Including the video card. My suggestion will be a fresh installation of the software. It lessen software-driver conflict and is direct configuration to your new set up. This can also a hardware ID conflict.

I want to upgrade my hard drive.

If you have 50% or more disk space free then you may not need a larger hard disk at this time. If you have 512Mb of RAM, you can get better performance with 1Gb or better still 2Gb of RAM if your Acer can support more than 1Gb of RAM.

Slow computer


YOu computer meet the average power requirement nowadays. HOwever if you want to make more faster performance. U only need to add more memory. 1Gb is faster than my computer which is 512Mb.

Ok adding more memory make the computer faster from 1 Gb to 2GB this is much faster.

hard drive is nothing to do with the performance of the system. its only a storage of all files.

but besure to know the model of the memory before you buy. it should be identical to your current memory.
