Im using Intel DH55TC motherboard with Intel core i3 processor.I've purchased this computer 4 months ago.The problem is computer is running good for sometime but after sometime it is not running(motherboard led is glowing, processor fan is running for sometime then it also stops and then again it will run then stops.this is what continuing).Restart button doesnt worked.When i switch off the power button and then switch on, again the same problem(computer is running for sometime and then stops) continues.Please help me to resolve this problem.

Here is a site that has the suggested RAM for your motherboard. And includes the complete spec sheet.

Update your MOBOs BIOS. also check the connection points on the mobo to see the SATA connection is impeded or messed up in any way.

RAM wont help you as much a graphix card would in your situation. buy one from the top here: http://www.videocardbenchmark.net/high_end_gpus.html

Unfortunately, these are old processors and I don't see any available new. Newegg.com lists a couple available as refurbished. You may be better off getting a new computer with either a Intel I3 or current AMD processor.

I wish that I had better news for you.

(do not attempt to use a CPU that your motherboard doesn't support. It probably won't boot.)

I do not believe any of that, I think you;'ve been lied to.
LEARN TO USE CPU TEMPERATURE APP.
hwifno32.
or cpu_z
learn the CPU will slow then shut down at 90C
50C is better temp, mine here Im tying on gen6 is 34c.
add a case fan.
heatsinks kept lint free?
fans all work and lint free.

one way to wreck a mob is upgrade to 95+ watt CPU on a mobo that only allows 65watts max.
that will wreck the MOBO VRM chips, overheating them.
no CPU told no answers will ever come easy.
i3-530 is 73watts. your mobo even allows 95 watt I7
seen here clear as day
so your case fans are bad. solved

How many years do you own that desktop computer? You have a problem with your Ram: Transcend: 2GB 1333 Mhz

Ram is always responsible to boot and run all system required by your computer
A defect ram cannot boot or not properly run application e.g.
Power-On-Self-Test (start up of your computer)
Booting your Operating System
Running your Application like Microsoft office , Photoshop and so on

Replace your Ram

Hi.
Yes, you have an i3 processor, which allows for blazing fast gaming graphics with the graphics media accelerator.
It supports directx 11, and has pixel shader 3.0 support as well.
It allows the processor to offload the graphics signal to the graphics portion of the motherboard, allowing the processor to work way more efficiently
It has support for vertex shaders as well as the normal pixel shaders, so graphics come alive.

Just check which type of graphic chipset that you have, and download the latest drivers for it.
Some have intel chips, some have ati, and others have nvidia.

They all work equally well for the most part, for games it seems that the nvidia chips appear to work a little smoother than the ati, but the ati has it's pluses as well. The ati chips can run at a faster overall speed.
Make sure that you set the AGP aperture to the maximum amount available in your bios settings

Intel Desktop Board DH55TC support for up to 16 GB of system memory DDR3. In order to achieve better speed, it is recommended that you may consider increasing RAM or adding a graphics card which would definately result in better performance.

On the software side, please make sure that you Operating System is working fine and properly tuned-up. Deleting unnecessary software etc would be beneficial.

Let me know if any further clarification/ assistance is required.

Good Luck!
Appreciate generously, if the solution could have been of any help!

Why don't you try installing XP service pack 3?
It has all updated files of SP1 & SP2:

below is the link for SP3:
