My problems first started on day when I was trying to install a new game that I had just gotten. It used installshield, and when I tried to install it, it gave me an error about not being able to create InstallDriver instance or something like that.
I consulted with google, and the Installshield Support page. It gave me a very detailed tutorial on how to fix this problem. So I followed it, and nothing would work. I spent a few hours and never got anything to work.
So right now I am installing programs and such on my brothers computer, then moving it over on to my omputer with my flash drive.
Ever since then I have had very serious problems with many things, such as I can't defragment, my computer will sometimes randomly shut down, and other very serious errors in games and programs and such.
The only antivirus program that I use is AVG by Grisoft, the anti spyware I use is SpyBot: Search & Destroy.
These are my computer specs:
Manufacturer: Compaq Desktop PC
Processor: AMD Athlon 64 Processor 3500+, MMX, 3DNow, ~2.2GHz
Memory: 446MB RAM
Hard Drive: 200gb
Video Card: NVIDIA GeForce 6150 LE
Sound Card: Realtek HD Audio rear output
Windows XP Professional (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_gdr.070227-2254)
Any kind of Help/Suggestions would be greatly appreciated. Thanks
