Blank screen on Qosmio f45 after power down when a program froze

I was updating McAffee virus online when the download quit responding. Task manager would not come up so I powered off then on. Starts to boot up then hit a blank flat line cursor screen. Can access BIOS but f5 anf f8 function keys will not let me access a restore partition or safe mode.

    Your problem sounds like mine. When I power it on I get a blank white bar, the Q logo, and the Phoenix BIOS logo. Then it goes to the white blinking cursor. Looks like the BIOS is bad. I called Toshiba looking for a way to reset it. He had me pull the battery and the power cord then press and hold the power button for 10 seconds to attempt a reset. You might try it, but it didn't work for me. I took the machine apart using the instructions athttp://www.irisvista.com/tech/laptops/To... to look for the BIOS reset button the CSR said was on the motherboard, but I can't find it. If you can, please let me know where to find it and what it looks like. Thanks, ahughes@san.rr.com

Try taking out the operating system then putting it back in and rebooting it.

I BELIEVE I AM MISSING A FILE CSINSTALL.INI FROM TOSHIBA SWUPDATE. IS THERE A FIX?


restore the machine to some date the machine was working before and then that restore was successful.
Proceed to install again the updates.
However you must RUN the antivirus and malware software for virus or malware.
Normally the HP has a software diagnostic and repair, use it and fix it.

God bless you

Blank screen


A white blank screen? That sounds like the virus changed your display settings. Click Ctrl+Alt+Del to get to the task manager. Press and hold the Ctrl key plus the Alt Key then hit the Del key. When the task manager opens up Click File at the upper left corner of the window then select New Task RUN. When the create New Task Window opens type: explorer.exe and hit OK. See if it starts populating your desktop icons and shows the start menu and task bar. If so, the virus changed your settings.

To change your display background click Start/Control Panel and look for Display or Appearance and Personalization. When it opens select the Desktop tab and change the desktop background. Hopefully the white will go away.

You may have to get into Safe Mode to do the above if the virus disabled the Task Manager.

Acer laptop curser froze and optical mouse does not work


There are many things that might cause your PC to run slowly or restart at time and then. It could be a fragmented disk; fragmented registry; a virus, Trojan, or spy ware; high CPU and/or utilization due to too many programs running; high disk I/O; or something else.

To check your CPU and memory utilization, run Task Manager. You can start Task Manager by pressing CTRL+ALT+DEL and then clicking on the Task Manager Button. In Task manager, click on the Performance tab and check CPU Usage and PF Usage. PF Usage is an indicator of memory usage. If one or both of these is high, click on the Processes tab, and sort the columns by CPU or Memory to see what processes are consuming the resource. If you are not sure what the process "Image name" is for, Google the name and you should find what the process is for.

If your CPU and memory usage are reasonable, then you may have a different issue. Even if you running anti-virus software, it may be beneficial to scan your PC with another scanner to check for viruses. No anti-virus software is 100% perfect at catching everything. Here are a few good free online virus scanners that you can run to check your PC:

An excellent free utility for overall system maintenance is Advanced System Care Free ( http://download.cnet.com/advanced-systemcare-free/3000-2086_4-10407614 .html ). I use this utility on a regular basis.

You should always run anti-virus software. There are several very good, free, anti-virus products available. One good source to read editor and user reviews, and safely download anti-virus software, is http://download.cnet.com -- search for free antivirus software. In addition to the reviews, you can see how many people are downloading the software, which is another good indicator of how popular it is.

I have used AVG Free ( http://download.cnet.com/avg-anti-virus-free/3000-2239_4-10320142.html ) , and Avast Free ( http://download.cnet.com/avast-free-antivirus/3000-2239_4-10019223.htm l ). Both are very good, and completely free. At present I am using Avast on all of my home computers.

I have heard good things about Avira AntiVir Free ( http://download.cnet.com/Avira-AntiVir-Personal-Free-Antivirus/3000-22 39_4-10322935.html ), and it has good ratings, but I have not personally tried it.

In addition to Avast or one of the other free anti-virus software packages, I also run Ad-Aware ( http://download.cnet.com/ad-aware-free-internet/3000-8022_4-10045910.h tml ). Ad-Aware is a free anti-malware, anti-spyware package.

Good luck!

My laptop Toshiba Qosmio F45- AV413 doesn't turn on. When I press the power button looks that will turn on, but shut down right after. All the lights looks fine, when I plug the power cable the light turn...


Take the battery out & see if it works then, perhaps the battery is so flat it is holding down the PC. It will should go on just the adapter. If this works, then you will have to plug battery back in, & adapter and leave alone for at least 8 hours. If it still won't work, you may need a new battery.

How do i fix the blue screen at boot with windows 7 on a qosmio f45


You most likely have a driver conflict if you get the "Blue Screen of Death". The screen has information on it to point to the problem area. If you are not a Tech you need someone to decipher the information and recommend a fix. Try booting into Safe-Mode by pressing the F5 key during the boot process. If Windows loads sucessfuly you can go to the Control Panel-System-Hardware-Device Manager and see what device or devices have an issue and load a new driver or updated driver from the device manufacturer. Good Luck! If all else fails and you just loaded Windows 7 you may need to format the drive and start over making certain you have all the latest drivers compatable with Windows 7 for your device's. It is best to go on the Web and collect the drivers in advance of loading 7.
