The display freezes up, but not with remote connection

Overview

This problem concerns my very old, but still-peppy emachine.

The specs

Emachine T6540
Windows 7 Home Premium, 32 bit
AMD Athlon X2
NVIDIA onboard chip: GEFORCE 6150 LE
4 GB RAM
No graphics card

The problem

This emachine runs great, but a few times a day, freezes up so that the display has diagonal grayish dashed lines and nothing works. It recovers fine after a reboot. I tried a different display cable, a different display, and an update to the device driver, but still no joy.

I figure maybe there's a problem with the NVIDIA chip? I'm not a hardware gal, so please tell me what other information you need.

I did do an experiment which might jump out at someone here:

I tried using "logmein" to get a remote connection to the emachine from my laptop, and guess what? It doesn't crash.

What could this mean in terms of where the problem really lies? I'm thinking that even with a remote connection, I am still using the emachine's NVIDIA onboard chip, no?

Also, what could be a remedy? Thanks!

Linda :help:

When was the last time that the inside was cleaned out of heat trapping dust?

Download Speedfan and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

The +3.3V and the +12V readings of your PSU are showing as being very low, download and run HWMonitor and post a screenshot of the readings http://www.cpuid.com.../hwmonitor.html

To capture and post a screenshot;

Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload...
then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.

Ok HWMonitor also reports the same low readings so lets try and confirm them with Everest;

Download and install http://www.filehippo...d_everest_home/

Open it.
1: In left pane expand Computer folder.
2: Click once on Summary
3: In upper menu, go Report
4: And then to Quick Report-Summary
5: Save it in text file, and paste it in your next post.
Click the + by computer, click on Sensor. Get a screenshot and post it so your temps and voltages can be checked.


DO NOT INCLUDE ANYTHING UNDER THE LINE THAT SAYS "DEBUG- PCI"

Uninstall the previous programs I had you use when you are ready :thumbsup:

3 out of 3 test programs report that your PSU is bad, the two suggestions I can make are borrow a known good PSU for testing on your PC or remove and take your present PSU to a tech who has the specialist equipment and knowledge to test your PSU.

See the table below for what your PSU outputs should be;

I realized today that I have another emachine power supply lying around so I tried it.

I *think* it's a good power supply that I'm trying. Here's why I think that: I had bought a new power supply a few years ago for a different emachine that had a noisy power supply. Once I swapped the new one in, I noticed that the noise continued, but it has continued to work so I gave up. In other words, there was no change.

So the power supply I'm trying now is the one I took out of that other emachine a few years ago.

And the numbers you were concerned about are EXACTLY the same now. And the freeze-ups are still happening.

What do you think? If we could assume for a moment that this trial power supply is good, what else could be wrong?

Phillpower2 has been an enormous help, as I now know more than I've ever known before how little I know. I'm not a gamer, so I never concerned myself with PSU's. Thank you Phillpower2!

But now that the replacement PSU is showing the same low voltages as the one I swapped out, I decided to run speedfan on a different emachine--the one my son uses to run games and which has never had a problem. Lo and behold, his power supply shows the same two low voltages that mine does.

So now my question is, could there be something else causing the freeze-ups on my emachine? Granted, a better PSU is a good idea but it doesn't seem logically that the PSU alone is causing the freeze-ups. I'm not even running games on mine. I'm using it like a mere mortal.

What else can I try? Anybody?

Hello stayathomegee
Please re-read my post #7;

Sorry if I am misinterpreting what you are stating but my suggestions were clear!

3 out of 3 test programs report that your PSU is bad, the two suggestions I can make are borrow a known good PSU for testing on your PC or remove and take your present PSU to a tech who has the specialist equipment and knowledge to test your PSU.
See the table below for what your PSU outputs should be;


I at no time suggested that you purchase a replacement PSU without previous testing!

I didn't purchase a psu. I had an extra one. So I thought I was doing what you suggested. I put in another psu for testing, but it produced the same results.

I was wondering what to do next. Thanks for sticking with me on this. I'm determined to figure this out, and I'm learning some things along the way.

Phew and thank goodness, I was worried that you had gone out and purchased a new PSU :whistling:


Please provide a screenshot of your temp and voltage readings with the replacements PSU :thumbsup:

Thanks for the screenshot :thumbsup:

While it is not unheard of it is unlikely that both PSUs are bad in such a way as to put out the same low voltages, this may be a problem with the motherboards voltage regulator which if it needs replacing is not a task that the average user can or should undertake, some information @ http://www.hardwares...r-Circuit/616/1 I am only suggesting that you read the free information and in no way suggesting that you use any other product or service at the link.

I still suggest that you get one or both PSUs tested by a Tech so as to rule them out as the cause, one other thing that you can try which is a long shot - try restoring the motherboards default factory settings by removing the silver CR2032 battery (see .jpeg) for a few minutes and then replace it, upon first boot you will need to go into the BIOS - reset the time and date - save (F10) and then Y to accept the new changes.
