Hi!
I have a problem with my HP a6230 computer (Windows Vista Home Edition SP 1).
I was installing updates a few days ago, and accidentally turned the PC off during the installation process.
Now it is really slow, I have to wait a couple of minutes just for icons to appear, the computer crashes whenever I try to open any program.
I cannot do anything. It works fine in Safe Mode, though.
Hard drive makes strange, repetitive noises.
I've scanned the PC - no malware was found.
I think my hard disk USES PIO mode, is there a way to change it to DMA? I can't do it in Safe Mode.

Thanks in advance,
ByteYou can try to do a 'SYSTEM restore'. That will revert back to the way the computer was before you started the UPDATE. Every time Vista starts an update it sets a restore point.

Type in 'System restore' in the search box and you should SEE it there. If in case no restore point or was turned off, try this http://www.vistax64.com/tutorials/88009-advanced-boot-options.html
and choose Last known good configuration.Thanks for your replies, but neither System Restore nor last known good configuration solved my problem.
Any more ideas?The reason the PC is slow is directly related to PIO mode...
If Windows detects 4 or 5 (cant remember which ) read/write errors it drops the HDD down to PIO mode.
I would DLoad the Free diagnostics from the HDD manuf. site ASAP and run it to check the health of the drive...
