Sony vaio pcv-rs510 fails to fully boot. Goes past initial windows screen then blanks out.... safe mode fails to boot as well... command lines just pile the screen.. need help plzz

Have you done any Hardware/Software Updates/Upgrades? Have you tried a System Restore/Recovery? Reseat the Memory mods, Graphic Card, etc. Try to boot to safe mode, Open msconfig, select Normal Startup, reboot. Let us know what the results are.

If you have an install disc boot to it, restart your PC hold down F12 and select the CD/DVD Drive. If it boots to disc, go to the command prompt then run SFC /scannow. This will run the system file checker and repair your files as well.

have you tried booting in safe mode?

as the system is booting repeatedly press F8 until a menu appears where you use the aarow keys to select safe mode by pressing enter.

Hello my friend this is looks like your graphic card is dying or your power supply.You should change your graphic card but if you hear any noise let me know

Just copy and paste. Right now you can get this unit for $399.00, new it ran around $899.00. But like anything else in the computer world one year you need to upgrade, two years you need upgrade, Three years you need to upgrade, forth year you need to buy a more up to date computer. I replace mine and use my others for back ups or sell them. If your selling yours and it is in good shape you could get up to $399.00 for it. Hope this helps.

I would recommend you try to do a installation repair. Do so by booting from the Windows install CD and choosing the repair option.

UBCD did not let me get info off of hard drive. Re-installed windows xp, problem ceased.

one of the files in the system32 directory in the windows folder is corrupt, the files in the system32 folder contains vital files for the boot procedure, try to start the machine in "safe mode" by pressing F8 after the sony boot screen, if it allows you into the operating system you will need to choose "system Restore" take the time back to at least a week before your problems started DO NOT CREATE A RESTORE POINT
