Just replaced a 9800GTX+ with 660TI and Windows 7 won't show up after drivers in
Last response: in Graphics & Displays
A couple of weeks ago my 9800GTX+ died (first there were some artifacts in windows, soon after artifacts in BIOS, then the computer stopped POSTing (with beeps leading to bad graphics card))
I decided to go for a gradual upgrade since I don't want to spend a ton of money right now. I read that even though my MB has PCI 1.0 there shouldn't be problems accommodating a newer gen graphics card so I went out and bought an ASUS GTX 660TI (DC2-2GD5)
As I installed the new gfx in the machine Windows 7 Pro recognized the new device, installed the drivers and asked for a reboot. But after the reboot Windows stopped loading. The computer POSTs fine and I can go into Safe Mode.
I have no fear of hardware, I work as an IT guy, but I cannot find the problem in this case. Could it be that the MB/whole PC is too old for this kind of gfx? Maybe the PCIe on the MB is dead or maybe it's the PSU, but the power leds on the 660TI are both green.
Between the 9800GTX+ and the new card I have used a small Nvidia PCIe 300 series replacement without any problem.
Here's my current setup:
PSU: ASUS 500W
MB: P5K Premium
CPU: Q6600 @ 3.2GHz (but also tried booting without OC -- same results)
RAM: 4GB
OS: Win 7 Professional (64 bit)
I was planning on upgrading the whole setup, but I hoped I could do it one step at a time so any help on getting the current config running properly would be appreciated.
Thank you

Found the problem: my PSU had one cord with two PCIe power adapters which was enough for my old 9800GTX+, but apparently not so for the new 660TI. Was inspired to use the 2 x MOLEX to one 6-pin PCIe power cable adapter provided with the 660TI to add another source of power for the second connector on the card. That solved my problem ![:)]( ":)")
Now I have to find money to mitigate the P5K+Q6600 bottleneck, which is quite substantial from what I can see. Nevertheless the graphics performance is much improved over the old card, at least benchmark wise.

I have a 219 watt GTX 570 that works fine with a dual connector cable ( Antec NeoEco520 powered it for testing ), and a 182 watt GTX 260 that does, and a 150 watt 660Ti
Currently powering the 660Ti with an Antec TP550 using the native pcie cable and a splitter
