I saw a similar topic while searching the forums that i assumed was completed.


I was running Firefox and Don't Starve (Steam) when I got a popup saying my Java version was insecure. I then got another popup from Windows saying something to the effect of it had detected a security problem, at which point it quickly shut all programs and then itself down. After a pause, it restarted itself and brought up a blank screen with a flashing underscore in the upper left hand side. Thinking this was a command prompt, I tried typing, but typing does nothing. In fact, the caps lock and num lock on my keyboard don't even work. Pressing the power button in this state immediately turns off the computer.


In the similar topic (the guy was also running Linux but only having this problem with Windows 7), the solution was to find your hard drive in the boot options of your BIOS and boot from that. I tried booting from every boot option in my BIOS and they all give the exact same result. I have no idea what this is. Any help?

A popup? saying that Java is insecure?

That sounds pretty darn sketchy to me... So by "cannot boot into any mode from the BIOS", do you mean you can't even boot into safe mode?

Also, did this sporadically occur or was it after you randomly clicked on/installed something?

Hi R-C,


What the advice was in a recent couple of posts was to tap the F8 key a couple of times while the BIOS screen was showing. This will either bring up the start-up options screen where you will see things like 'Run Windows in Safe Mode'  and 'Start Windows normally' OR it will bring up a screen called something like 'Boot options'. In the case of the computer I was working on, it was this screen that held the solution to the blinking cursor and nothing happening problem.


The computer I was working on was fitted with two DVD drives and one active hard drive. This screen gave me the options 'DVD 1', 'HDD 1' or 'DVD 2'. Selecting - eventually - the hard drive solved my problem and I was able to do a normal install of Win 7. If however, you get the start-up options screen, try starting in 'Safe Mode with networking' and see what happens.


Try the above and post back, but it may be that you have acquired a malware problem which will need to be resolved.
