Then give us a model number. 2007 HP PC doesn't help.
We need things like:
■CPU type and speed (Intel, AMD, Dual Core, Quad Core, X3, X4, etc)
■Video card - make and amount of memory
■Amount of system memory
■Sound card
Without that information, we cannot help you at all. It's not that we don't want to, we just can't without that information. If you can't get the info yourself, maybe someone you know can?
