I recently replaced a DC7100 CMT (running Windows XP) with a DC7900 CMT (running Windows 7 64). I had installed a Soundblaster Audio card and a Gigabyte 8600 GT (Silent Pipe) in the 7100, they worked fine. I installed the Soundblaster card in the 7900 no problems. However installing the 8600 card results in no boot/black screen and after around 15 seconds the fans kick in hard until it is switched off. ![]() Install and update all Hp Compaq® dc7900 Windows® drivers.

Have tried using both PCI slots, no difference. I have some basic knowlege but not much more. The card is fairly low wattage (around 40 watts) and worked fine with the lower wattage PSU in the 7100. Any ideas Thanks. Welcome to the forum. I have reviewed the specs of the workstation and the video card. The only possible discrepency that I can find is, the specs for the card state that the card was developed for Win XP and Vista. They don't mention Win 7. I have never seen this cause a problem in the past, but nothing else stands out as a problem. I suggest that you contact Gigabytes Tech Support to see if they can help you.

Desktop PCs are finding themselves usurped by laptops in more and more workplaces, but if power and value are more important to you than portability, a compact business desktop should still be at the top of your list. HP Compaq's dc-range of desktops are a familiar sight in PC Pro's labs, but now its small-form-factor model has received an internal makeover courtesy of Intel's latest Q45 Express chipset. Don't be misled by the SFF moniker however, the dc7900 isn't nearly as compact as the likes of HP's own dc Ultra-slim models, nor the likes of. Its 378 x 337mm footprint is hardly giant-sized, but if desk space is at a real premium, it's worth bearing in mind. However, if you can make the room, the dc7900 has plenty to recommend it. Where more compact models have to resort to cramming laptop components inside their more diminutive chassis, the dc7900 makes room for fully-fledged desktop parts, which makes both upgrading and replacing broken parts significantly cheaper and easier. And, although the core specification may not look like much, it punches far above its mid-range price. The Core 2 Duo E8500 processor is one of Intel's recent 45nm parts, and its efficiency helps keep cooling, noise and power consumption to an absolute minimum. The whole PC is amply cooled by a quiet 92mm fan which draws air in through the front vent, over the passive CPU heatsink and out the back of the case. At idle, the dc7900 consumes just 35W. Push the E8500 to its limits and its power consumption rises to 69W, but thanks to its two cores running at 3.16GHz the performance on offer is staggering. Our benchmarks returned a score of 1.94 - that's no doubt aided by the presence of XP Professional as the OS of choice, but it still amounts to by far the best benchmark result we've ever seen from a business PC. 3D performance isn't quite so remarkable, or necessary for that matter given the dc7900's target audience, but the Intel GMA 4500 graphics are more capable than the generations they replace. A result of 14fps in our least demanding Crysis benchmark is a reasonable showing for an integrated graphics chipset, but it's hardly what you'd call playable. Externally, that austere silver and black plastic fascia is the same as ever, with two front mounted USB ports sitting below two handy, front-facing audio minijacks. Move to the rear and you'll find another six USB ports, a serial port, a VGA socket and, more notably, DisplayPort makes its debut in HPs business range, too. Look closer, however, and there's more of evidence of keen and sensible attention to detail. Indeed, removing the top cover is as simple as depressing two buttons on each side of the chassis. Peer inside and although the innards look relatively cramped, HP has made it easy to get at everything. For example, the 250GB hard disk sits underneath the PSU, but press the green tab and the PSU neatly tilts back out of the way, allowing for easy access. The 2GB of DDR2 memory is comprised of two full-sized 1GB sticks in dual-channel operation, and two slots are left empty for future upgrades. There are two spare SATA ports, a PCI slot, two PCI-E 16x slots and one single PCI-E 1x slot too.
