Windows 7 freezes when playing video in fullscreen mode

I checked the RAM voltages in he BIOS and it is set to 1.5v, the amount that the RAM specs say

Thanks for your reply!

...because I think I may have to get new RAM (everytime I start up it gives me the three beeps, then I get it up and running, turn it on...same thing)

I was wondering though if there was a way to confirm that the RAM itself was bad....

Just incompatible. I've lost count of the times people "test" the ram in another machine. What did that prove? (yes I'm asking you.)

The test is to try another stick but from the motherboard's supported ram listings. Then if that fails we do the usuals of resetting the CMOS (people can and have mis-set that!) and then we swap out the motherboard.

but I will try again

I checked the listings for my motherboard (http://www.intel.com/support/motherboards/desktop/dp45sg/sb/CS-029151.htm) and it seems like there is not many 2gb sticks. Is it guaranteed to work even if it is not the exact same model but from the same company?

Thanks

In case you missed it, my answer is NO. It MIGHT WORK, it might not. The motherboard maker publishes a list of parts they tested. When you're off the list they may or may not swap the board under warranty.

Remember you asked me if it was guaranteed to work.

that is 100% guarnteed to work. It solved the beeping issue (yay!) but alas, the video problem still persists.

I managed to get a streaming DivX file loaded and playing in fullscreen mode just fine

Since we are dealing with an unreleased OS, drivers no one will stand behind plus a home built machine, it's almost amazing that this is the only issue.

What other released OS can you use?

So I tried a streaming the same DivX file in fullscreen mode in Win 7 and it worked! Then I tried a flash video and it froze. I will try to reinstall flash and see what happens

We may be onto something here. The flash 64 bit player has a bit of history. If this is the issue, time to read posts about that and start waiting for "them" to fix that.

Thanks for your help! I will look around the Adobe forums and see what I can find. I am relieved that it is not a hardware issue as I already had to deal with some RAM issues early on.

Thanks again

I tried watching some videos in VLC (not even fullscrenn mode)encoded in h.264 as well as an AVI and it crashed my machine both times

and have come to the conclusion that it is a hardware problem.

I ran the sample file that comes with Windows Media Player in fullscreen mode, and sure enough, it locked up compleltly. Same with Oblivion, I ran it at Medium settings in Windowed Mode and it locked up as well.

Any ideas?

Tell me EXACTLY in painful detail about the CPU, the heatsink compound and the heatsink, fan installation. Typical findings are (a) no compound, (b) 3 out of 4 retainers are in place (what? All of them are needed?) (c) "I unplugged the noisy fans."

The CPU is an Intel Core 2 Quad Q9550 @ 2.83GHz. The heat sink and fan are installed properly (all 4 retainers are firmly in place) All the fans are running well and there is compound on the CPU

Just one stick of RAM for a test run. This forces most machines to take a breather (run slower) and can reveal the hardware issue.

If that works you call the suppliers and ask what they want to swap out.

I booted with I RAM stick in (2gb) and the video still froze

I did the 1 stick RAM test rebooted, didn't work, inserted the RAM back in, booted up and now I can play avi, divx and whatever format the Mailbag HD podcast comes in...all in Windows Media Player. Still no flash though...

I tried skipping through an avi file...froze!

Could this be a faulty graphics card, I cant think of anything else!

..turns out that everything works splendid in Ubuntu 32bit without a hitch.

I will install either Uubntu 64 or Vista 64 and hopefully the problem should go away (hopefully its not a 64bit issue)

I just tried the Ubuntu 32 live cd and everything, and I mean everything, worked well. Streaming DivX and Flash fullscreen (same vids as tested on other OSes) Even my avi from my external hardrive was streaming fine in fullscreen mode.

So, what does this mean? Do I have to remove 4gb of RAM or can I make this work?

Thanks for all your help so far!

I installed Ubuntu 64bit and now it is running fine. I don't know what the issue was, but I installed some drivers and some plugins and now it works flawlessly.

Thanks for all your help!

Shortly after I installed Ubuntu 64, it started happening again, turns out the video card was dead (even though it was new) I got an nVidia card and it runs fine under Win 7 64bit...
