Arbitrary Lines in Autocad

[1drafter]

I'm a Autocad drafter. I run both Autocad R14 and R2000. At present I am forced to run Windows 95 because anything higher than Win95m, I get handle error exceptions and when I begin to draw there are arbitrary lines all over the screen from the mouse without entering anything in the command line. This is in both versions of AutoCad. I am also getting a runtime error. With Win 95 becoming extinct and un-supported I would love to be able to run higher Windows software ... but find these errors occur both in Win 98 SE (full version) and Windows ME (add on). I also moonlight as Web/Graphics Designer and find all kinds of pixel distortion occurs in my graphics. I have a 1.1 gig AMD Duron processor and on-board graphics & sound. But this also occurred when I had a graphics card under my old system (486 processor) .. and I tried to load Win 98. So I don't think it's a necessity to buy a graphics card. I've formatted and re-installed Win98 SE and tried Autocad without my graphics software among other things but still no resolve but to remain with Win95. If anyone else has had this problem, can you please help me in resolving this pre-historic - trapped in time dilema. Thanks for your help ... ahead of time!

Whenever you get the arbitrary lines, such as the lines of your crosshairs being left all over your screen, many times it has to do with not having enough physical and virtual memory. Win98se is better than 95, but not as stable as WinXP. Add as much memory as your motherboard will allow, and clean up your temporary files. With 95 and 98, Norton SystemWorks helped keep my computer running smoother. In Win95 and 98, I doubled the megs of the physical ram and this is the setting to set the virtual memory (256megs of physical ram = 512megs of virtual ram). Also in Win95 and 98, you don't want to leave it running for several days in a row, you need to reboot it every couple of days.

Until I upgraded my hard drive to 30 gig the problem was still occuring with 8 gig hard-drive and 256k ram. Wouldn't that be enough ram on the 8 gig? I now have 30 gig hard-drive and the 256 ram but the problem is resolved once I stay with Win95. Thanks so much for your previous reply.

Contact your tech support quickly before tech support for Autocad 2000 terminates (early January 2004) When I first bought ACAD 2000 I was told by my local tech support people not to run Autocad with any CPU other than an Intel Pentium. I don't know if this is still true or not (AMD could have made updates since then).

Just for background, I had a similar plotting problem years ago (lots of random lines) and it turned out to be a parallel port card that was incompatible with the plotter. You may have a similar problem with your CPU.
