In need of a little help

I'm currently trying to access my RCT 2 on my computer at home. When I try to load it I get a message saying unaccesible or lost file. The worst thing is when ever I try to unintall it.... it goes threw all its steps but then tells me maintenence on Roller coaster tycoon was succesful... The other computer I have blue screened the last time I was playing RCT 3 on it. I have some saying Harddrive or Virtual Memory problems. I just know I havent touched it since. Any ideas.....I could use the help.

Hard Drive or Virtual Memory problems are big problems. Hard drive errors could mean you need a new hard drive soon!!! You may want to crack open your computer (if out of warranty) and blow out any dust inside it. Virtual memory you will need to increase the size of your paging file. Click start -> Control Panel -> double click System -> on tabs at top click on Advanced -> On next window pop up click on Advanced tab again -> go to Virtual Memory section and click on change -> in there increase the number of the virtual memory. You also may want to scan for viruses, trojans, worms, and spyware. For more help I suggest going to tech websites for troubleshooting tips. I dont believe your issue is with RCT2 or RCT3 at this time.
