Slow PC - Why?

I have a desktop that is as slow as 'ell. I have got rid of old, unwanted progs, cleaned the registry, disk cleaned, defraged and doubled the RAM to 1gb. It is an AMD Athlon XP2800 running XP.
I ran Malewarebytes and it took two and threequarter hours to check the disk. I am currently ronning Microsoft Security Essentials and that has been going for an hour and a half and still isn't finished. It has an 80gb HDisk with 60gb of free space so there isn't much on it. Apart from a total reformat, is there anything else I can do?

Just wondered if you removed your previous Anti-Virus program using the proper removal tool.
What anti-virus were you using.
Maybe update your drivers.
Driver Max free is fairly good but will only update 2 drivers a day so it might take a few days.

Check that all of the fans are clean and the airflow is ok. Other than that it may be best to bite the bullet and do a re-install of Windows.

Was running AVG but removed through Add/Remove and can see no traces there. Will give drivermax a whirl. Thanks

Thanks Woolwell. Hae checked CPU temp and it is showing as 55c which seems very cool although I have the side off the PC at the moment. Think as you say I'll bite the bullet and reformat but having done everything I just wished I knew why it is going so ruddy slow.

Noticed that you used Add/remove Programmes to remove AVG. I have had problems with my sons laptop running AVG 9 and when googling found that there were problems experienced using Add/Remove Programmes and the advice appeared to be to download AVG uninstaller to remove all AVG components. This worked for me and there were just one or two folders to deleted manually see here click here.

Also check task manager to see what's using the CPU most.

Well it's back to the dear old reformat/reinstall. A pain in the rear job but sometimes it seems to be the only answer!!

Nothing showing in task manager?

might be worth checking your security for restricted sites...
Tools, internet options, security, restricted sites, sites.
Some cleaning tools like spybot can put hundreds of sites in this area to stop malicious sites getting at your PC..however I've found that they can seriously slow down your machine. There is a small program called deldomains
click here which clears these entires out.

Worth a shot before formatting.
