One of Trouble Fixers reader, Pritam, reported a problem saying “After installing RAM display comes but OS did not load. and system restarts automatically“.

Strange co-incidence is that today only I bought some new RAM for one of my friends computer and I too faced such issue. I tried installing it on my computer and my computer also did not boot with new RAM. It was restarting again and again and again, not loading windows.

One thing I realized on comparing the RAM module which I am using and the new one is the number of Memory Chips on memory module.

Let us see in details.

Fix:

On observing closely,I found that there are 8 Memory chips on the new module on front side and no chip on the rear side as you can see in the above picture .

The module which I am using is having 8 chips on front and 8 at the back.

This simply means that each chip on new RAM is high density chip and contains twice the memory as compared to the old module. Due to this high density memory, my old motherboard is not able to read it properly and thus is not booting normally.

So next time you want to upgrade ram, be sure that the one you are buying is compatible with the old computer that you have. See this post for some more precautions before buying a RAM.

I didn’t have such good luck. Now I will find some of my friend whose computer can handle it, or I will get back to the vendor and ask him for a replacement with a compatible version.

After installing new RAM display comes but Windows does not load is a post from TroubleFixers - All about fixing computer troubles

Some times we turn on the computer and it does not turn on. There is no beep (sometimes many beeps in a pattern), or any kind of display and the computer does not boot. This happens when POST (power on self test) for the computer fails. Lets see why this happens and what to do in such cases.

Fix:

POST(power on self test) is a test which is done by the computer every time it is powered on. This test, all the physical hardware components of the computer are detected and tested for proper working. If any of the critical computer component is faulty or not detected, the POST fails. After this test fails, the computer does not go further and does not boot. There can be several reasons for failure of POST.

One of the most common reason is faulty or loose RAM module. So next time your computer does not give a beep at start-up and does not boot, perform the following checks.

• Check that the RAM module is properly inserted in the RAM slot. If not, correct it.
• If there is lots of dust around it, clean it with a DRY cloth gently. If needed, remove the RAM module from the RAM slot carefully and clean the contacts with DRY cloth and insert it back carefully.

The above two checks will Fix the trouble in most of the cases.

NOTE: If there are more than one beeps in some pattern and the computer is not starting, refer to the beep code corresponding to your BIOS to know the reason for failure see this link.

No beep at start-up. Computer does not boot. is a post from TroubleFixers - All about fixing computer troubles

Are facing troubles in running latest application software or games that demand a lot of RAM?

You may be feeling the need to upgrade your RAM?

But If you are going to add another RAM module to increase the RAM size without removing the old module, it may cause more troubles than good. Let us see the troubles that you may face:

• Poor performance even after increasing the RAM.
• System becomes unstable and restarts abruptly.
• Only one of the two RAM modules is detected.
• New RAM module is not detected.

Now lets us have a look at the precautions that you should take to avoid the above mentioned problems.

Fix:

• If your computer motherboard has dual channel memory support ( see the motherboard’s user manual), then you must install two identical RAM modules for best performance. For best performance, put the two modules in two different memory channels (see motherboard manual for correct way of installation). So you can buy an identical RAM module as your existing module, or better approach would be to sell off the existing one and buy two new of same type, brand, capacity and frequency.
• If your computer’s motherboard does not support dual channel memory support, then it is recommended that you replace your old RAM module with a new module of higher capacity. But before you buy a new RAM module, check your motherboard’s manual for maximum RAM frequency it supports, buy the new module of the maximum supported frequency for good performance.
• If you want to add a new RAM module without removing the old one(not recommended), it is highly recommended that the two modules (old and new one) must be of same memory frequency. If the frequency is not same, system becomes unstable and restarts abruptly, which can be fatal for your computer.
• In case the two RAM modules are based on different chipset technology (which changes the memory density, i.e the memory contained on each chip on the module), it may happen that only one one of the two is detected.
• If the memory density of the new RAM module is not supported by your motherboard, it may happen that the new RAM module is not detected at all. So be very careful before buying a new memory module. Buy only after checking the supported memory types from motherboard’s manual.

So, The thumb-rule is – Always look carefully into the motherboard’s user manual before any kind of RAM upgrades.
