2gb Corsair DDR2 RAM

Win XP SP3
Now understandably the 2nd computer is rather bleep, but it wasn't this bad on Monday. It's absolutely shocking now, it's like it's buffering/lagging for a minute or so, then runs normal, then lags again. I've tried everything on your list, I've replaced the thermal paste, cleaned out the dust, crapcleaner, atf cleaner, updated all my drivers, windows, even disabled ctfmon. But it's still the same. The 1st computer isn't nearly as bad, but it did ask me to revalidate windows on the first boot.
Things I've noticed common to both computers
- On restart, it says my active desktop is disabled. I've got rainmeter running on both.
- A program called sysdiag64.exe was running on both, it created a registry key with the value MSN in the startup folder
- Both have had BSOD errors
I booted in safemode, ran eset scan on comp 2 and avg on comp 1, removed the bad registry key on both and sysdiag64.exe hasn't shown again. HJT logs on both show nothing unusual, virus scans now come empty. Performance on comp1 is better.
Anyway, I'm positive it's something nasty. Any help would be appreciated.
