Problems with new graphics card/modem

  Leejg 17:16 23 Feb 2003

I've just replaced my Graphics card and modem (Inno Tornado gf 4 mx440). Since then the pc freezes regulary requiring a reset. It happens mostly when I try to connect to the internet but not always. The modem was installed first for a week and there didn't seem to be a problem.
Any ideas

Come on folks there must be someone with some advice.

Don't know if this will help but worth trying, I had a similar problem with my nephews PC though it related to graphics and sound cards.

Go do device manager select the devices and make sure IRQ sharing is enabled, reboot and see if it solves the problem.

Failing that, remove both cards, re-install the graphics card first, shut down and reboot, and then re-install the modem, this should allow the modem to select a different IRQ AND hopefully cure the problem.

As I say might be totally unrelated, but worth trying failing anyone coming up with a better solution

Where would I find IRQ sharing I've just been on device manager and cannot see it.
Ps I'm running win Me

I've just re-installed both the graphics card and modem but still same problem, any more ideas?
Could it be a problem with extra power consumption, I replaced a TNT2 Riva card.

remove the old drivers before upgrading the video card? When you reboot with the new card point ME in the direction of the latest driver you downloaded and, all should be ok. Modems can be tempremental, install the latest driver before you phisically install the modem.

Does any body know what power a general Pc will take using a gf4. My psu is rated at 135w. is this too low and could it be the cause of the computer freezing up. Sometimes the monitor switches it self into standby.

135 sounds low to me.

I'd suggest a minimum of 250, preferably 300+

my self think it is the psu, for a geforce 4 you
do need some where near 300 watts for the power supply .I have a ati radeon 9500 and it has to be powered from the poer supply seperately.
So ask in apc shop but 135 watts is too low.

Thanks everyone with a quick calculation from MartinT's reply I'm looking at about 300w. Does any think that fitting a new psu will solve my problem.
