For your information,
This evening, despite the fact that I did not believe that the PSU is causing my girlfriends problem, I replaced her PSU to a Xilence 800W.
For spec: http://www.levicom.de/xilence/en/xp800.(135)r.htm
The only things that was connected to the motherboard was AMD X2 4200+, 1GB DIMM (only one module), 80GB WD IDE harddrive, 1 DVD Optiarc AD-5170IDE and GeCube HD2600Pro. Noting else was applied to the system.
The system crached when trying to install the driver for the grafic board, HD2600Pro! Vista was started in Fail safe mode and splashed that it had recovered from a seriuos system fault.
I made a fresh, clean installation, formatting the hard drive first. Once again when the OS was installed it crashed as soon as the driver for the board should be installed.
It all works in fail safe mode. It also works if the XP driver is installed in Vista but then the Aero function of Vista does not work. The display resolution can be fixed at max level (1650 * 1200 and 32 bit). As soon as the Vista driver for HD2600Pro is installed the system craches! Only way to get the system to work is to remove the driver while in Fail Safe mode. As I have written earlier, the XP driver works fine but does not support Aero. With the XP driver for HD2600Pro installed in Vista the system is stable.
All this with Xilence 800W power supply! The PSU is normally used in a system that runs XFX GF8800GT 512MB, 2*1GB PC6400 DIMM, AMD X2 6000+ , WD 320GB 16MB SATA II, Optiarc AD-5170IDE and 2 fans, one in front and one in rear panel.
This just confirms the fact that the PSU has nothing to do with the problem, what so ever!
Yes, the onboard VGA works but does not support Aero. The HD2600Pro displays a better resolution, using the XP driver in Vista, than the on board VGA does.
Last year, in September, I built a system for a friend using MSI K9VGM motherboard. AMD X2 4200+ and 1GB PC4300 was all that was installed and I used a 300W PSU. The system had big problems booting! Note that only motherboard, CPU and one DIMM was in use. I posted my problem here and the standard reply was then as it is now, replace the PSU.
I ended up using a 550W Corsair PSU for the system, once again despite my believe in that the PSU was the root of the cause.
Did the Corsair 550W PSU solve the problem? Nope!
The problem was the motherboard! When replacing the motherboard the system booted every time, even with the 300W PSU. I got the motherboard replaced by warranty. I then completed building the PC and it still works fine today, using 300W PSU.
Now I have posted another question, a driver can not be installed running Vista. Your reply is the very same standard reply, blame the PSU.
Bas, you have something to learn about the relation between Volt and Amperé. Watts is for real and have a big importance in the relationship.
Yes Fredrik, one should have open mind! That is certanily something needed on this Forum. If you had an open mind, if you would like to try to help, (I am a member on another site and I am supporting others when they have problems. But I only respond on issues that I know about and they are a lot) when someone declaires a problem, do not throw your standard reply, Blame the PSU. Try to think a bit more, openminded, what can cause such a problem and not always blame the PSU.
I have been working a lot with solving problems with PCs and I have come across one PC with PSU problems only. I have had about 55 PCs with different problems and only one with PSU issue. The rest have had some kind of hardware or driver problem.
Yes! I have found the root that causes the problem with my girlfriend PC and her new HD2600Pro grafic board. I have spent 6 hours this evening, looking for the root to the cause.
As you already know it is NOT the PSU. Now her own PSU is back into the system and the GeCube HD2600Pro Vista driver is installed with a fully functional Aero.
She has the very same hardware (no hardware has been replaced and will not be replaced) as from the start and it is all working fine now. I even know how to recall the fault, whenever I want!
I do not expect that you are interested in the root of the cause to the problem is as you only want to blame the PSU. In this case it is NOT the PSU.
This is my last posting on this site. PSU is not the cause to all PC problems but it is the standard reply here, Blame the PSU.
Regards and goodbye.
