Windows 7 Screen Freeze

March 22, 2012 at 04:06:05
Specs: Windows 7 Untimate, 2GB
eMachine T3120
Fresh Clean Install Windows 7
Fairly New WD 250GB SATA
Nvidia Geforce 6100 on board/Nvidia Geforce 6500 Add in being used
No other add in cards
Brand New 2GB (1GB x2) DDR 800
Belkin N300 Wireless USB Adapter

Ok here is another headache I took on. Someone gave me this emachine and I was like, hey I will fix it up a bit for one of the kids, now I am loosing hair again.

So far I changed out the HD, RAM, added Belkin N300 Wireless USB Adapter and clean installed windows 7 nothing else. When I first got the PC it only had 512MB of RAM and the HD sounded like it was eating itself. The original HD was IDE but the board supports SATA so I threw in this drive I had laying around that hadnt seen much use. The RAM I picked up for a good price and it was much needed compared to 512MB. Based on the PC specs I figured that the PC would be up to windows 7 and so I did a clean install removing the previous OS Ubuntu. Here is where it gets strange.

The PC sat in my office for almost a week turned on and my daughter played on it off and on. She plays java/flash based educational games, watches shows on netflix and dvd movies via WMP. The PC ran crisp and great the whole entire time, even better then I thought it would. Then, I setup a desk in my daughter's room and move the PC in there. The first time I turn it on and open up IE the screen freezes, like a still frame. The PC makes no change in sound, just keeps running as normal but the screen, just frozen.

At first the issue only happened when launching IE. The PC ran awesome, I could run anything besides an internet browser. If I click IE the page would load fine but as soon as I would click anywhere or start to type the screen freezes. Now though, as long as I dont touch IE things are ok but out of no where at any random moment the screen freezes.

I have tryed disconnecting everything except what is needed to run the PC (defaulting to the on board GPU) and no change other then when the screen freezes there are a few vertical colored lines and the screen gets a little blurry. With the wireless adapter removed (no internet) the browser opens no problem but I still get the random freezes. I tryed a different monitor, the old memory, pulling the MoBo battery/resetting the bios, reinstalling windows 7, uninstalling and wiping adobe flash, tryed a clean boot. I cant find anywhere to get a bios update, all drivers are up to date and so is windows.

Booting in safe mode with networking nets me no freezes and full browser use.

Don't bother with a BIOS update, it is not worth the risk and there is no indication that it would fix anything here.
I suspect you may have needed to upgrade your power supply when you upgraded the graphics card.
Have you tried reseating all connectors to make sure one of them has not become loose when you moved the machine?
Have you downloaded the latest drivers from the video card mfg's website?
Have you tried a scan with Malwarebytes in Safe Mode?

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

It actually wasnt me that upgraded the gfx card it had the 6500 add in already in there. Yes I made sure everything was seated right. All drivers were brought up to date right after doing a clean install of windows and updating windows, including the gfx drivers. Malwarebytes comes back with nothing.

emachines typically come with inexpensive power supplies, even if it was enough previously, it may be going and now supplying enough power.
Boot into BIOS set up and read the voltages there, they need to be within 5% of the nominal values (the 12V +- 5%, the same for the 3.3V & 5V). If they are further out than that then it should be replaced. If you have a decent power supply around, you may want to try swapping them out to be sure anyway.

While you are in your BIOS check the temperatures, if they are high or rising, you probably have a lot of dust build up that needs to be cleaned out or a non-working fan. Clean out with a can of compressed air. You can also check your temps from within Windows with Speedfan or HWMonitor installed.

Have you tried different browsers (IE, Firefox, Chrome)?

When you did a 'Clean Install', did you delete the partition, create a new one and format it? If you did not delete the partition then some root infections could have survived the reinstall. Also if you suspect that type of issue, you could also select the 'Full Format' option rather than the 'Quick Format' option since the Full Format writes '0' in every location (though it can take a couple of hours to complete).

I will check all that out and try out this power supply that I know works. I did do a clean install and did delete and create a new partition. Yes different browsers same outcome. What intrigues me is that It can go for long periods even playing a DVD movie full screen before freezing yet, as soon as I open a browser and click it freezes every time.

Bios says cpu temp is riding at 30c +-5. Voltages are spot on or a tad higher. Cleaned out the little bit of dust. Still going to try the other PSU just to know I did.

Ok so I guess it ends on a wierd note also. I pulled one of the new memory sticks out to see if one of them fouled out. No freezing at all. I put the one I pulled out in and took the other one out to make sure and the PC still works no freezing. Really? So I put them both in and bam freezing. This MoBo said it takes 2GB of memory I dont understand.

So I put in the 512MB with one of the new 1GB sticks and no freezing. What sense does that make? Does it make sense?
