Keep restarting every 5-10mins. was inf motherboard bad


Restarting loop in your computer can be caused various reasons.

1. Overheating of the processor.
2. Problem with your operating system
3. Motherboard failures

While restarting your computer you should be seeing the Sony logo and then the windows logo, post which you will go to your desktop background. If your computer is restarting immediately after the windows logo before loading windows desktop, then the problem can also be with the windows operating system. For this situation while your computer is restarting keep tapping the F8 key as soon as you see the sony logo, then choose safe mode and hit enter, This should load safe mode, in safe mode wait for some time and see if your computer is restarting. if not then the issue is with some recently made change or recently installed software or hardware. If it restarts even from safe then the issue is with the hardware of your computer

When i turn my computer dell latitude d620 on it comes to the dell screen then the windows xp screen and then it goes black with nothing more than the mouse. what could be the problem?


This sounds like a video issue. Try starting the system into safe mode (after the dell screen, tap F8 to get the startup menu and then select safe mode) When in safe mode, go to the control panel and remove the display adapter driver from the device manager under System > hardware tab. Try booting into normal mode windows- you should be able to get into windows at that point. Download and reinstall the graphics driver from support.dell.com. If the issue reoccurs after you've reinstalled the graphics driver, it means that the video card on your system has gone out. At that point, contact Dell technical support if you are in warranty to get service- if not, try pricing the replacement video card from Ebay or Dell parts service.

Dell Inspiron 1525 Laptop..the screen goes almost black after 5 minutes.


The screen goes black while in normal mode right? So try to boot in safe mode (power on then keep tapping F8 then select safe mode). Check if still happens in safe mode.

If screen does not goes black in safe mode it means there might be a software or driver causes problem when running in normal mode. You can try the following (update your anti virus software then run a full system scan, uninstall the video driver then download and install the latest one, uninstall any previous windows update or you can system restore to the time when it was working fine).

If the screen goes black even in safe mode they try connecting the laptop to an external monitor if still goes black, if yes then absolutely no issues with the LCD panel. You can try (uninstall and reinstall the video driver if still persist then this might end up replacing video card or motherboard, but before doing that update the BIOS first).

If does not goes black in ext monitor then the LCD panel might causes the problem. Reseat the LCD cable or inverter if you can.

Computer randomly shuts down in Safe Mode only


I can't think of any reason why you would want to run in safe mode except if the computer crashes your system. If you have a heat problem in safe mode it is shutting down to protect you CPU and GPU which are two things you won't want to replace. If you are over clocking you CPU that could cause this problem as the power management system is not active in Windows when you run safe mode. If your system is under warranty and you are concerned about this problem ask them to do a warranty repair. If it's not under warranty you can take it to Best buy and explain the problem and ask for a PC health check. Last I heard they were still doing those for free. At this point though I would avoid running the PC in Safe Mode

Computer not booting -> Blue Screen


You can try running a repair on the operating system, but the hard drive could be damaged. If so, the repair will fail. Hopefully the hard drive is the only thing broken.
