I have dell gx270 tower pc with 2.6gh procesor(800mh).what higher processr of what specification can it support?

I did some research into your motherboard for that dell and found that it uses the Intel 865G motherboard. Which uses Intel Pentium IV Socket 478 proccessors.
Any Socket 478 Pentium IV processor will work in that board. the best processor I could find for that was the Pentium IV 3.4Ghz but it was $231..
However, I did find the Pentium IV 3.2Ghz for only $15.99. that seems to be the best deal to me. That would be a fair speed increase, an extra 0.6Ghz or 600Mhz.
Here is the link:

Also if you need to get a new heat sync you can search for "Pentium IV Heatsync" or "Socket 478 Heatsync" in google or a sight like

I have this old laptop and its called a compaq (presario 2500) well yesterday i brought the sims3 game for it because the laptop dosent have internet. When i installed the game it says windows xp has to...


Thanks for using fixya.

My name is Carlo.

Your computer might not pass the system requirements that's why it has an error. Or, you can try installing it one more time and check if it will work. Computers do mess up sometimes.

Here's the system requirement of SIMS 3:

Desktop PC (Windows XP + SP2):
CPU: 2ghz Pentium4 Processor or Amd Athlon 2000+ Processor
RAM: 1 GB of RAM
GPU: 128mb Video Card (GeForce FX 5900 or Radeon 9500)

Desktop PC (Windows Vista + SP1):
CPU: 2ghz Pentium4 Processor or Amd Athlon 2400+ Processor
RAM: 1.5 GB of RAM
GPU: 128mb Video Card (GeForce FX 5900 or Radeon 9500)

Laptop (Windows XP + SP2):
CPU: 2ghz Pentium4 Processor or Amd Athlon 2000+ Processor
RAM: 1.5 GB of RAM
GPU: 128mb Video Card (GeForce Go 6200 or Radeon 9600)

Laptop (Windows Vista + SP1):
CPU: 2ghz Pentium4 Processor or Amd Athlon 2400+ Processor
RAM: 2 GB of RAM
GPU: 128mb Video Card (GeForce Go 6200 or Radeon 9600)

IF your computer does not pass the system requirement, then you cannot play sims3 in your computer.

I hope this helps. Thank you for using fixya

Just brought new memory for my acer aspire sa90 desktop,now my computer doesn't seem to turn on

i assume computer was starting correctly before? this is older computer and it is using sdram memory, locket on them sometime do not clip in correctly.

1. switch off computer
2. remove power cord
3. remove side wall
4. remove sdram
5. check sdram orientation and type, if they correctly align with registering notches
6. release lockets to max, (outward from slot)
7. re-insert correctly oriented sdram till lockets close into sdram stick (you may give them bit "help" to close in position)
8. re-connect power
9. start computer

if copmuter start normally, that meant tha tyou fixed the problem, if not, switch computer off and remove power cable, check motherboard power cable insertion, and repower again.

if computer start, lose cable was the problem.

if computer still do not start, remove new memory and re-nstall old one, if computer start, new memory will be a culprit.

if computer no fan "jig" and no light blink, remove all power supply cables from motherboard and connect in it's place new power supply, to exclude power supply problem.

if computer start with new power supply, old power supply will be the problem,

if computer do not start, and no joy with checking, but fan is running, including on the processor, this will indicate either, motherboard or processor died... if that is the case further testing will be required to determine which is exact cause. as in home situation there are usually no motherboard testing equipment, you need to go to more difficult path of changing the processor, checking video and haveing second computer on which you can test all of that...

replacement board for that processor on ebay cost from about $0.99 plus postage. if you need any further advice, please re-post adn if i am on line today, i will provide you with further procedure how to test your video, motherboard and processor.

if you find my advice useful, please do not hesitate to leave your comment and vote 4 for me, thanx!

The pc is switching on and then off after 5 minutes

There are several factors that could cause the above problem in your diagnoses.

A) Processor Fan is not operating, or not spinning at the set speed desired. (RPM. Revolutions Per Minute) Fan bearings are bad.
Replace processor fan.

Computer case open, observe the Processor fan as soon as you start the computer.
If the fan is not spinning, shut the computer down.
(Hold the Power On button in for a count of 10 seconds)

Observe if the fan spins slowly, or spins for a while, stops, then spins again.

B) Failing Electrolytic Capacitors on the motherboard.
C) Power Supply has a weak voltage power rail.

Failing Capacitors on the Motherboard.
Electrolytic Capacitors.
Specifically the one's used in the motherboard Voltage Regulator Circuit.

A Processor must have a Steady, Clean, supply of voltage.
The tolerance range is Very small.
Too little, or too much voltage, the Processor turns off.
[BIOS turns it off]

Part of what the motherboard voltage regulator circuit does, is to regulate voltage for the Processor.

This link gives information about what Electrolytic Capacitors look like installed on a motherboard, and photos plus info, about the visual signs of Electrolytic Capacitor failure,

(Computer unplugged from power. Observe Anti-Static Guidelines. Need more info about the last sentence, please post in a Comment)

Requires either replacing the failing capacitors, or replace the motherboard if bad capacitors are found.

If upon a close scrutiny with a flashlight, and magnifying glass, does not reveal visual signs of capacitor failure, then the next hardware component to check is the Power Supply.

3) Power Supply's have Electrolytic Capacitors also.
A computer power supply changes AC (Alternating Current) electricity from a household, or business, into DC electricity.
(Direct Current. A flashlight battery is an example of stored DC electricity)

Electrolytic Capacitors are used as Filters in a computer power supply.
They filter the incoming AC (Input Stage), and the outgoing DC (Output Stage)

Generally I have found that these are the weakest link, and are the first hardware component to fail in a PSU. (Power Supply Unit)

There is a way to test the Power Supply.
Requires either a multimeter, or a Power Supply Tester, or using a KNOWN to be good, compatible power supply to substitute, and use as a test unit.

An economical multimeter can be purchased for around $10 to $15 at many stores. An auto parts store usually carries them.
An economical power supply tester can be purchased for around $20.

This is an example of a power supply tester,

Computer dirty inside, as well as the inside of the Power Supply, will cause detrimental factors to the computer.

1) Dust is a Static magnet. Dust can create pathways for static electricity to follow, and the DC electricity used for a computer.
This can cause hardware components inside the computer to Short Circuit. (Fry out)

2) Dust, dirt, hair, etc, can clog the cooling components of the computer.
The computer case fan/s, the Processor fan, and Heatsink, and the Power Supply fan, and Heatsink/s located inside the Power Supply.

Air is drawn in through the front of a computer, (Or on some custom PC's through the side), and flows over the hardware components inside the computer, helping to cool them.

If a layer of dust, dirt, hair, and so on, has coated these hardware components, the heat will be trapped, and the air flow will not be able to carry the heat away.

If the computer case fan's are coated, their cooling capacity drops tremendously also. The fan, or fans, will not be able to provide the air flow needed.

If the Processor fan, and Heatsink are coated, the cooling capacity of these two components drops tremendously.
A Processor has a thermal temperature it can operate in, and will turn off if the temperature is exceeded.

It's a Fail Safe feature that is built-in, to keep the Processor from burning up.

[A Heatsink is essentially a plate of metal that has tall, thin fins protruding from it. Heat is absorbed into the plate, whereby it is then absorbed by the tall, thin fins.
Air flows in-between the fins, and helps carry the heat away.

This is an example of an average Fan/Heatsink combo,

The Heatsink is the aluminum finned part sitting under the fan.

Using a can of compressed air for computers, on a regular basis as needed, can help prevent many computer failures.

To summarize:

1) Check the Processor fan. If the computer is dirty inside, there is the obvious factor for it's failing.
2) Check the capacitors on the motherboard visually.
3) Test the power supply, or substitute it with a Known to be good, compatible unit for a test.

Must have at least the same amount of Wattage, or more.
Must have all the correct power cables needed.
Must have enough of the correct cables]

What diameter is the processor fan?

its not a standard diameter for a pentium4, ime not sure of the diameter as dell does not list it and the actual fan is on the case , ported to the pentium4 cpu covered with a heat sinc. Your best bet is to physically measure it or take it with you when you buy a new fan. If you have the outside dimentions ,the correct screw hole pattern and it fits under the plastic shroud, you have the correct fan..

I need a bigger cpu

The largest pentium 4 processor on the market is the 3.4 ghz pentium 4 processor it comes in extreme edition but thats rather pricey. Your motherboard should be able to support it. Your computer will probably support up to 4 gigs of ram.

Cpu upgrade dell dimension 5100

Hi, according to the Dell website you have a LGA775 socket on your motherboard. Therefore, you can only buy processors that fit into this socket. Here is a list of some offered by Intel that will work: Celeron D 325 2.53 GHz Celeron D 330 2.66 GHz Celeron D 335 2.8 GHz Celeron D 340 2.93 GHz Pentium4 520 2.8 GHz Pentium4 530 3.0 GHz Pentium4 540 3.2GHz Pentium4 550 3.4 GHz Pentium4 560 3.6 GHz Pentium4 570 3.8 GHz The processors that won't work are the ones that are not compatible with this socket. Everytime you look up a cpu it will tell you which socket it is designed for. To buy a cpu you will need to decide: The brand you want. The speed of the cpu that you want. Extras i.e. Hyperthreading, etc. How much you are willing to pay for it. Then you can narrow your search as you stick within your limits. Let me know if you have more questions. Good Luck
