I have an older Dell Studio laptop with Vista Home Premium 64 bit (yuk!) and it now boots to a WHITE screen after briefly displaying the windows desktop (about 3 seconds). I cannot enter Task Manager, Command Prompt or safe mode. The only other account is a Guest account and it has no admin rights. Finally, the only OS CD I have is for Vista HP 32 bit and it will not run repair install. The CD drive is very slow and I don't believe it's working properly.
HOW can I fix the white bootup issue or remove the malware with these limitations? I can remove the HDD and run a manual scan with another system if necessary.
