Are the beeps coming from the motherboard or the video card?What power management mode setting do you use?If the cards are overclocked try running them at stock. If nothing else works do you have another pc to try the card in?

Not sure why it wouldn't do it at startup but continuous long beeps usually means the video card is not seated properly. I do know that EVGA had bios updates for certain 560's for low voltage causing high pitched squealing when under heavy load,not sure about MSI.

Is your MB bios up to date? If your plugged into a UPS, try direct to the wall plug. Are the beeps random or are they long and short?

You want to use the strongest form of encryption that all of your Wi-Fi devices support.For me that's WPA2.WEP encryption is easily broken.

To eliminate power as the issue, disable SLI in the Nvidia control panel and try the game and see if it crashes

Did you check the box on the bottom left that says "show more restore points"

Acronis does have a cloning feature,have used it and works well.The newer versions have full SSD support; kb.acronis.com/content/2699

You said earlier in your posts that your power supply was 750 watt.What brand is it?The gtx295 requires a minimum of 680 watts.The 750 watt might have been just enough when new but as it has aged it may no longer be supplying the card with enough power.If it's a no name brand I would suspect a power issue even more.This would also assume that you are having 2 separate issues between your desktop and your laptop.

55c & 37c are good temps,fingers crossed.

What is the video card temp when it crashes?

No need to get out of game to check temps.MSI afterburner has an on screen display server and will display fan speeds and card temperature on screen in the game

You can download the user manual for afterburner here: event.msi.com/vga/afterburner/download.htm More than likely it was opening to the system tray.Both precision and afterburner are written buy the same person,they are fairly easy to set up.Once set up it will control the fan automatically to your settings and display your temps on screen while in the game. If you don't have any program installed for graphics fan speed,I suspect your video card over your cpu as the problem.If you want to check it anyway post a pick of your cpu fan and we'll see if we can tell you how to take it off. If you want to see if the video card is the problem,you can download "Nvidia Inspector" which requires no installation,just run the program,take fan off of auto and turn up manually and try a game and see what happens; downloads.guru3d.com/NVIDIA-Inspector-1.94-download-2612.html

No pinching of prongs! Turn the black knobs on the heatsink in the direction of the arrow 90 degrees and pull up to release. More than likely your video card fan is running on auto from the cards bios,not good for a gtx295.Install EVGA precision or MSI afterberner and create a custom fan profile to ramp up the fan speed as the card heats up.

Make sure everything is still seated properly,power cables, video card, memory,etc. You can run this program and it will analyze the crash dump from the blue screen and show you what was involved in the crash; www.resplendence.com/whocrashed

Same for me,unplayable.
