Hi, all. First post here.

I have an IBM Aptiva 2140 with a Pentium MMX 266mhz and 384MB of ram. The motherboard has PCI and ISA slots, but no AGP slots. The only card in the system when I got it was an ISA ethernet card. I purchased a PCI PNY GeForce FX 5200 256MB from ebay. I do get video output, but only the BIOS screen, then followed by a fast flashing white cursor and black background. I cannot seem to actuallyt enter the BIOS either when the card is installed, only see the spash screen. I've tried a different power supply and it made no difference. I also tried using a different PCI slot, which also made no difference. I've also tried both VGA ports, again with no difference. If I touch the heatsink on the GPU after powering the system off, it is warm so it seems the card itself is getting power. The CMOS battery was just replaced a week ago as I'm getting this system up and running after having been mostly just stored since 2015. The only other things connected are an IDE CD-ROM drive, floppy drive, and IDE hard drive. I am simply wondering if this card is "too new" for this old system. I also did update the BIOS prior to installing the card.

I chose this card becasue it was affodable and I figured "a bit overkill but nice" for Windows 95. I also intended to tinker with Windows 98/ME/2000 and possibly even XP (and maybe even linux) on a separate drive and wanted plenty of GPU headroom at a decent price. I also saw ahead of time there are drivers available for Win9x (inclucding 95) for the FX5200. Also notworhty is the hard drive still has its factory installation of Windows 95 from 1997 and feels like a piece of history at this point, hence why I'll never reformat it.

If anyone has any other suggestions to attempt to get this card to work or for other PCI cards I may be able to purchase, please let me know.

Thanks!
