Virus or PC problem?


Sounds like a hardware problem. And since your computer is failing like that, my guess is it is the hard drive making that noise. You need to isolate the location of that noise. If it is coming from the hard drive I suggest you back up your data *immediately* using some kind of CDROM based disk imaging software where you can boot to the cd (so you use the hard drive as little as possible). One such program is Image For Linux (http://www.terabyteunlimited.com/image-for-linux.htm)

I have a Toshiba Portege M400. It runs ok if I leave it on a flat surface. However, if I try to move it the screen freezes up and the fan starts running very loudly. I am unable to do anything except cut power and start the computer up again. Recently I have also had problems getting it to start unless the screen is in a particular position.


Sounds like there might be dust inside of the laptop that is blocking one of the air vents. Plus the connectors to the screen may need to be reseated so that way the screen can be moved freely without it locking up on you and cutting off. You have two issues going on. Bring it to somebody so they can open it up and make sure the air vents are cleaned out. Also they need to make sure the CPU fan is running properly. Then with the screen the connectors need to be reseated. Its also quite possible the screen connector might need to be replaced. If the laptop is under warranty see if Toshiba will reapir it.

FixYa solutions for every thing Resent problems with my Gateway CX200X Tablet PC made me believe it was infected beyond a virus scan repair. It would NOT let me Virus scan, quick restore to a previous date, go to safe mode it would divert to set up screen and it would not read restore disc. I took out the internal battery and exterior battery over night and the next day quick restored to a month earlier then full scanned twice with Microsoft Essentials, cleaned the disc and defragged. It still would divert to setup screen instead of safe mode. MSN Messenger would repeatedly return to startup list after running msconfig, even though I removed it from the computer. The last straw was when after many adjustments to Power options, the screen would turn off not the hard drive or go into standby. Nor, would the screen come back on. I manually induced standby using the FN and F3 buttons. It worked, for about a half hour when the computer started on it's own. After saving what I needed off the hard drive to a Flash Stick, I full restored using the 2 discs except just before it was done (about 93%) it would turn off the laptop. Restart would show blue screen showing, NTLDR is missing. I removed the receiver for wireless mouse and... Restored again, and c000021a (fatal system error). Restored again, "windows could not start the following is missing or corrupt: windows root>\system32\ntsoskrnl.exe" Restored again, windows could not start the following is missing or corrupt: windows root>\system32\HAL,DLL. Restored again, windows could not start the following is missing or corrupt: windows root>\system32\RMCast.sys Is the corruption on the hard drive or in deeper? Would replacing the HDD be the cure?

It doesn´t start up. Maybe mother board problem...


Best bet may be to look for a second Laptop for spare parts use boteh to fix one and then sell the remaining spare parts. Or sell yours for spare parts and you buy a new one.

Blank Screen Aloha, I am having a problem with my Toshiba Satellite R-15. I was on it the other night when the screen went blank and it was was still running. I thought the battery or the connection was the problem,so I turned the power off and the laptop would boot up and still no monitor. I did turn the screen so it was on tablet mode,when this all happened and the screen was on for about a minute or so thats when it went blank(do not know if that makes a difference or not) Do you have any suggestions on what to do? I do not have a reference manual to help troubleshoot. Mahalos Willy J


The bad thing about this is that it could be a software related issue or a hardware issue. If you're willing, you can disassemble the unit and check for a damaged or loose connector to the monitor. If there doesn't appear to be any issues there it may well be that the screen has gone bad or there is something wrong with the driver/setting on the unit itself that is causing the screen to saty off. I'd move forward with the hardware issue first though.

Clock of the computer


This means that the cmos battery on the motherboard is flat and keeps losing time and date and probably the memory settings, this is only a small disc shaped watch type battery CR2032 and can be found on the motherboard, a pc repair shop would be able to do it for you for a small fee.
