Computer screen totally white(white screen of death)

[zip316]

Hi to all, I restarted my computer last night and on restarting it came up with a totally white screen.The only thing I can do is the old ctrl alt delete and it only shows a black screen with lock,switch user,shut down, task manager and cancel. On my phone I asked Google and it said go into repair tool or safe mode but I cant do any of that. Anybody experience this ?

Not happened to me but try a restart into safe mode: if you can

Restart the computer.
At the sign-in screen, hold the Shift key down and then click Power > Restart.
After the computer restarts to the Choose an Option screen, select Troubleshoot > Advanced Options > Startup Settings > Restart.
After the computer restarts, a list of options should appear. Select 4 or F4 to start the computer in Safe Mode. If you must use the Internet, select 5 or F5 for Safe Mode with Networking.
