How to repair a VMWare which corrupted my WinXP host filesystem

I have a VMWare Workstation 6.5 on WinXP host with Ubuntu guest. Sometimes the guest OS responds real slowly and at other times it works normally.

Recently in addition the C: drive on my host cannot be opened in the windows explorer anymore! It gives two simultaneous error messages: One from VMware (even if nothing related to VMware is running at all) and one from Explorer - I attach images of the error messages.

What can I do? By the way, chkdsk doesn't find errors on the C disk.

You might have some bad RAM in your machine.  Shut it down and try reseating it first before pulling a stick at a time to figure out if it's hardware.

I already thought about it, but a memory testing program said the RAM is OK.... Could the it still be a bad module?

I meant to assign 500 points to this question!

Do a reinstall/repair of Workstation to see if that helps.

Do you have the option to upgrade your Workstation to 7.1? You might want to just do that instead of repairing your older version.

Ok...I guess you'd have to pay for the upgrade I just found out:

Thanks for your interest!

I am currently trying something to see if can lead to the problem or even solve it.

On a separate disk (OK, it's slower) I am booting into another winXP which also has a VMware, in which I open the Ubuntu guest OS (the VM data is located on the first, questionalbe HD).

I also took out the RAM modules and put them back, just in case.

I will see how it works out and let you guys know...

I have found that my harddisk (which is an OCZ Vertex Solid State Drive) is malfunctioning. It will try to get a replacement/repair.
Cheers!

Update:
Indeed the OCZ SSD was faulty, but the machine was still slow after I replaced it. Two indepentendt problems, tricky.

It turns out that there was a problem with the BIOS of the Dell E6400 series; it throttled down (a lot) the CPU clock frequency even when the CPU/GPU isn't particularly hot. Difficult to discover unless you have a CPU-clock monitor. Apparently Dell was reluctant to admit the problem but in the mean time it's actually been fixed in new BIOS version. I updated to BIOS version A25 and the problem is gone.
