Hi Again(!) I'm having problems with a Globalwin CAK4-88T. Before changing the clock speed to 133 from 100 the whole system worked fine. But after changing the fan takes ages to come upto speed which in turn freezes the PC. It does boot into Windows (XP Home) and is OK after doing a restart from there! Any ideas? Gaz

Why not change the bus speed back if was running fine?

You can't change the clock speed to a faster setting with the assumption that everything will be fine. Anytime that you deviate from the settings that you're supposed to have, you can only *HOPE* that everything will continue to run normal, or better yet, even better. What you did, may have been too radical of a change for the computer mobo or the chip. Of course you neglected to provide us with more details such as CPU type and speed, or any other problems that may have started since making the changes. When you swap out a fan/heatsink combo for a better one, you also have to apply new thermal grease for that to work properly. But again, moving up to a better fan/heatsink combo, does not mean that your chip or mobo will *ACCEPT* any changes that you want to make to them. If you can visually attest to the fact that the computer develops a "quirk" due to a slow moving fan, then you're probably about to burn something out since a fan should never start or run slow - thus causing immediate and potentially detrimental heat increases on the chip. I agree, go back to your old setup if that worked without any problems at all. A potentially UNSTABLE PC is the next thing that you'd have to deal with. Hey Intel, AMD rulez!

PC Setup: ACorp 7KT333 MOBO XP 2000 CPU 2 x 256MB PC2100 DDR 40GB Maxtor HDD 300W Switching PSU What I forgot to mention was that I simply changed the CPU Clock Frequency setting to match that of the CPU (133), so no major change was actually made. So switching back to the original set-up of 100MHz (CPU) will simply decrease the CPU performance. No other problems have been noticed. Once in Windows everything is OK.

"Ummm, simply changed the CPU Clock Frequency setting" ??? Did you build this computer? According to the AMD specs for an XP2000 processor, it's supposed to be running at a FSB of 133/266 anyway. You just changed the setting to that which it is supposed to have already. You do need good cooling with AMD chips though, since they run pretty hot to begin with. Also, the 300 Watt power supply is a little mediocre. Even AMD recommends a minimum of 350 Watt - another reason that makes me think you built the machine yourself. As long as you don't put a bunch of stuff in that box, you may not have a problem, but if you decide to run a CDRW and DVD drive as well as additional add-on cards, all of which require more juice while generating more heat, then you might definitely want to switch to a 350 watt or even a 400 watt power supply. Better safe than sorry ... Hey Intel, AMD rulez!

Hi again, i've now replaced the PSU with an Enermax 350 and also replaced the fan as the old one was still running way to slow (2800RPM). The new fan is now running happily at 4000RPM! Problem solved you may think! I'm still ecountering lock-ups when getting booting the PC. It will detect the drives and then go no further. It does still however let you into the BIOS. It also rebooted itself after entering Windows. I'm beginning to think there is an issue between: a) Memory or b) the troublesome graphics card Any thoughts?
