VERY WIERD: Mouse and Keyboard crapping out after 30 seconds of usage

Like the title suggests, this is a very wierd problem. Just bought a Maxtor to replace my dieing 75GXP. Formatted, partitioned, and installed WinXP Pro. Setup worked fine, installation went along, but when I boot into WinXP, log in, and start to work, the mouse and keyboard both stop functioning after 10-30 seconds. The first time, I thought that winXP just crapped out on me, but then i realized that the light underneath my Microsoft Optical Mouse just turned off. I plugged both my keyboard and mouse into another USB slot and low and behold, they work again - but only for 30 seconds before crapping out. I tried plugging both into their original USB slots (I only have 4 on my computer), but I can't revive em this time. I tried the same, using a USB to PS/2 adapter but that didn't help. I then thought that it was a bad installation of winXP, so I go and try to reinstall, but while working through the installation the keyboard and mouse crap out again....what's going on here?!?! I'm working on my roomie's comp, and tried my mouse and keyboard here.....both working fine, and longer than 30 seconds 😛 Possible power supply problem?

I've got a 300watt power supply pushing juice to:
1gig athie on abit ka7-100
sb live platinum
hercules gf2 32mb
3com nic
ati tv wonder ve
512mb ram
liteon 24x
pioneer 16x dvd
30gig ibm 75gxp (still alive...but not for long probably)
60gig maxtor
4 case fans (80mm)
2 cpu fans (40mm, i think)
1 hard drive fan (20mm, i think)
 
Yeah - that smells like a P/S problem. USB devices draw power from the mobo, etc. Why not store the USB ones and try a couple of PS/2 ones - - - keyboard and mobo. If you are going to use USB with a wiimpy P/S, you need a USB hub with its own power brick. That works better. But I like the keyboard and mouse in the PS/2 ports because that IRQ (12) is normally not used by anything else - thos devices also always work in DOS w/o having to load special config files and drivers.
 
Really? Wimpy power supply? I thought 300watts would be sufficient....guess not. Why would changing the two to PS/2 make a difference though???
 
I think corky is suggesting that if you use a PS/2 mouse...it would be used on its own IRQ address (suggesting that your mouse/keyboard problem might be caused by an IRQ conflict). Plus, PS/2 uses less power than USB.

As for the PS problem...a 300W doesn't necessarily mean its good. Wattage means nothing if the 3.3V and 5V rails are low.
