Hi
I'm not very knowledgeable about computers. Mine has been crashing and been much unusable lately, and I really need help.

I have:
core 2 dual 6600 @ 2.4ghz
2 nvidia 7900 gs cards
2gb ddr2 RAM

It was running well and the crashing started suddenly. I don't remember having installed any new drivers/apps or changed any major components. Hardware wise, everything was the same. It seems to be a combination of errors and crashing, and I seem to get a couple scenarios (I don't know what causes which to happen):

1-the screen freezes and the computer locks up, audio loops itself like a broken record
2-applications freeze (toolbars, windows, everything except my mouse which eventually freezes too), audio cuts off, and further action eventually causes EVERYthing to lockup and the computer lets out 1 continuous beep (goes on forever)
3-out of nowhere (usually after 5 minutes of bootup/logon without me running any additional apps) screen dies, blue screen of death with "IQRL not less or equal"
all three require me to hit the power button. I can't even use the computer anymore.

I swapped out ram with new sticks that I know work and tried different arrangements. I updated to latest nvidia drivers; I also uninstalled the old ones and reinstalled the new drivers (was i supposed to?). Coretemp is telling me my temperatures are 27C and 27C, and all my fans are spinning properly.
I don't know if this helps, but PF Usage in task manager is 200-250mb most of the time, and cpu and rest seems normal. I left my computer running idle all last night with no problems, but when I ran firefox and a game this morning it crashed again. It seems most unstable when I USE the computer
I also ran AVG2008, adaware, spybot, and a couple other but found no virus/malware other than cookies.
Computer runs fine in safe mode (doing this in safe mode right now) and (usually fine) in normal idle conditions. It feels like it's overloading with menial tasks when I run in normal mode.

What seems to be the problem (how can I check/does this seem to be hardware)?
What does the long continuous beep mean?
How can I find what's broken?

Please help! Thank you!

Is the long continuous beep on start up? There is usually short beeps to go with it and could be a video card. You have two video cards. Have you tried with just one? Safe mode only loads basic necessary drivers. Sounds like a hardware issure. You should try only one stick of ram and one video card and go from there.

I had what sounds like the same problem with my old tower and it turned out to be my CPU had burnt up!

Are you sure that your motherboard supports that amount or RAM?

And as mel8again said, if it is running fine in Safe Mode, then it is defiantly hardware related. I would also make sure that all of your drivers are fully updated to the most stable release.

Have you run Checkdisk (scandisk)????? Sounds like a bad hard drive in the page file area. it happens a lot.

do you get any errors from the bluescreen (i.e. 0cx0000004f) that can help a lot.
Do those errors change?
