Computer Freezes/Screen slightly dithers

October 4, 2012 at 16:22:06
Specs: Windows 7 Untimate, 2GB
EMachine T3120

Within secs-mins the computer freezes and is unresponsive but does not crash (also happens in safe mode). The screen seems to dither and sometimes there is tiny color specs. Rebooting the computer will boot back up no problem and seem absolutely fine till you try to do something then within secs to mins it freezes. Memtest says the memory is fine, Hitachi fitness test says HD is fine, the Bios reports the PSU voltage is fine, Speedfan reports the temperatures are staying cool, there are no add in cards, no conflicts in device manager, nothing in the event viewer, all drivers/system is up to date, monitor tested on another computer and works perfectly.

Let me know if I missed something and thank you for the help.

Malware can cause these types of problems among others...start with a quick scan using Malwarebytes and fix all it finds:
Also, try unchecking everything in startup using msconfig except for microsoft services and your AV

Sounds like video driver problem. Try to reinstall it.

It is still possible that you have a driver problem or wrong driver. Try downloading the latest drivers from the mfg's site and installing again.

It could be that your power supply has enough to maintain the correct voltage while in the BIOS set up, but does not have enough available current to power everything under loads that do not appear when in BIOS set up. Post ALL hardware specs including makes and models, especially on your power supply, include also the Wattage and Amperage on all of the individual rails (3.3V. 5V, 12V(list each if more than one), etc.).

You have to be a little bit crazy to keep you from going insane.

When I said it was a fresh install that was applied to the malware not the drivers. I will get the exact hardware specs of everything soon I was just plugging for ideas with what I had so far because I had to unhook the computer and hook up a working one for my daughter to use. Thank you.

ARGH!! This system says 2GB RAM Max. I installed 2GB RAM. I took out one of the sticks and so far it has not frozen. I swapped them out and still the same. The system so far does not freeze with just one of either of the sticks installed.

How does that make any sense?? Help Please!

How are u placing ur sticks of ram exactly ? are they 2 x 1GB sticks ? are they the same speed ? ur board has only 2 DIMMS in which u can install ur ram in so that will be a problem it would be better if u get a 2GB stick pc3200
DDR400 and install it without having 2 x 1GB sticks.

computers are a second home

I am using a 2GB (1GB x2) Kit. They are the same company and the same exact sticks as they came in the same kit.

With the both installed Memtest reports after 10 passes, zero errors.

The strange thing is, if I remove one of the sticks and put in one of my 512MB sticks the computer runs normal. I have switched out the 1GB sticks in this situation to and it still runs normal. It is almost as if the whole problem is when it reaches 2GB of RAM.

I have looked all over everywhere for a BIOS update thinking there may have been an issue but I cant find one anywhere. I dont know what to do anymore but use 1.5GB of ram with one of the higher quality 1GB sticks and one of the 512MB value RAMS. This is very frustrating and confusing.

Side note: Both the Bios and Windows recognize that there is 2GB of RAM installed.

I can even run WoW be it 10fps with only 1.5GB of RAM installed without any freezing or crashing...

I guess it will be chalked up as another of my unsolved mysteries.
