OK. All of a sudden, overnight our PC is running SLOWWW!
We've tried everything of which Im about to list. Sometimes, it will pick up, but it doesnt last long. Right now Im on my laptop, hubby has left me to go to a Man U match and Im trying to resolve the issue as I need this PC!!
Checked RAM and processor, all ok. We have quite a new PC top spec.
NAV running  - nothing picked up. Ive run HiJack this but the results dont mean much. Can post results if u wish, but is it any good running HiJAck this in safe mode?
We've reloaded windows, still very very slow. (Vista Home Prem)
I'm running nice and fast in safe mode.

Sounds like a corrupt system files, windows repair reinstalltion should do the trick. Use your Vista disk to boot from and select repair when asked.

Do you have automatic updates active? Your pc may have installed something during last shutdown

Strecher:
We re-installed windows over the top last night. Hasnt worked.

ai ja nai:
We deleted the last windows update as we suspected that and also took off the two pieces of software he had iinstalled, which was PSP 9 video convertor and a video convertor for the ipod, both made by the same guy.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Maybe corrupt hard drive as well. Try downloading and using HDD Regenerator or HDAT2 to clean up bad sectors on your hard drive, saved me couple of times.

Yep Norton still scanning HKEY_USERS\S-1-5-21-2279102648-2189364479-2094666144-1002\Software\Microsoft\Windows\CurrentVersion\Run
Seems to be stuck.
Could this be because Im running it in safe mode with networking?

Strecher, would a corrupt hard drive cause all of these problems? And then running in safe mode appear ok.
Thanks

You can get to Run registry keys by typing msconfig in Run tool in windows start menu or by pressing Win+r.

Corrupt hard drive might take a long time to boot into windows, even 1 or 2 bad sectors would cause corruption. Scan usually taked few hours depending on size of your hard drive. You only need to scan hdd that has system files on such as C:. No harm done by scanning it though.

No, it will scan before booting to Windows altogether.

You might need to change boot sequence settings in BIOS to boot from floppy or CD.

Its not making any sense for them to have to go through all these steps as they stated they reloaded windows and it was still a problem.  You say it was over night do you have any USB devices that you installed recently?  Any thumbdrives or anything that you are leaving plugged in?  Try unplugging all your usb devices and see what happens to the system after you boot it up.  I dont see a pagefile being full or a program surviving a format and reinstall of course i did watch the sasser worm reinstall after complete format and install on a system till it was killed so it is possible but unlikely.

Hello donnaaa5dcp

No problem on unchecking the startup items, its just a temporary test of slowing of speed, you can check any important checkable items if the problem is solve step by step.

About the pagefile, is a temporary memory storage if windows system.
you can access it by right clicking my computer properties, then find advance tabmenu, then soon you will find the pagefile allocation, put 0.

apply,ok.

3.Restart.
4.when system is back, Delete the windows\Prefetch folder.
5.Set again your pagefile to default or Let System Manage the Size.
6.Restart.
7.when system is back, Go back to msconfig, startup, then select the possible startup item option to check.
8.Restart


Done.

If it doesn't work, repeat it with safe-mode, by pressing f8 after power on.


Great is our GOD.
