I'm putting together a SFF used computer for a friend, and I managed to get a used GTX 745 for a pretty cheap price.
The computer I'm putting it in had a GT 210 with which it works perfectly, but is insufficient for her needs. (The comp is a Lenovo m90 with a i3-540). The GTX 745 I got works perfectly well when I put it in my computer, with it running benchmarks as I expected without any crashing or freezes.
The lenovo in question also works perfectly when I put the GT 210 in it (Win 10 installed).

But when I put the GTX 745 in, all that happens is the motherboard beeping 5 times, which, according to lenovo's troubleshooting page, means that something is wrong with the display.
(I followed everything they recommended on the troubleshooting page, to no avail)

Anyone have any ideas?
 
Solution


In that case it's a motherboard incompatibility or power supply issue, neither of which can be solved without spending more than the computer is worth

I tried it, it didn't solve the problem, though now atleast the Bios is at the latest version.
