Losing control...

I few weeks ago I replaced my Greenie BX chip cooler with a giant Slot1 Celeron heatink + fan because of overclocking.
A few days passed and all was fine, but all of a sudden i started losing control of the PC. My USB keyboard + mouse weren't repsonding. So, i unplugged + plugged back in to my USB 2.0 PCI card. Worked for a few minutes but then died again!

After a rest and reboot everything was fine. I figure the chipset is still overheating and instead of crashing it just kills USB. Everything still works, my network, video and sound stays intact. It's not a power issue don't think, because i had dual PSU's ( 500 combined watts) for a while and it still happened.

I can work around this, I've got a spare PS/2 keyboard plugged in for safety. This issue seems to be completely random as it cuts out independantly of rescource use. I can be running games and it'll go or just browsing the internet. What's most irritating is that the whole problem goes away for days, only to happen again when i least expect it.

Does anyone have any better explanations or fixes?

Explaination...no.
But fix...yes.

Stick with the ps2 keyboard and mouse, and use the USB keyboard and mouse on a newer system.

Um, how exactly are you holding that giant Slot1 Celeron heatink + fan on the where a Greene came off?

well the USB for some unexplained reason is very likely to go off when overclocking...though i don't know why, 'cause you are on the 33MHz PCI! there might be a heat issue...

there is some fix in the BIOS for the PS/2 port...but i cannot find it right now...try to browse a little on the forum and it may come up...

and a nice thign you did...i also put the old big Pentium heatsink with Celeron cooler on it...it works great...no freezes anymore!

It took a whole lot of work a Dremel rotary tool. (i think i spelled it right.)
I had to cut, sand and bend into the sides of the heatsink to make room for the little plastic screw-clip things i saved from the greenie. So the whole thing is held on by those two plastic clips.

I shoud have taken pictures of the heatsink, it's a work of art. Maybe if i get bored I'll pull everything apart and get some pics.

HOORAY! i got the keyboard/mouse working on PS/2 rather than USB! (It came with an adapter)
I had troubles getting the mouse to work in windows on PS/2 the first time i installed it, but i think I had the mouse powered off

It's all good now! The mouse even seems to work better on PS/2; it responds faster. How odd....

Anyway thanks for the help. For some reason i never thought of just using PS/2.

two fixes:
1. might work for USB port, in BIOS go to CHIPSET FEATURES SETUP and ENABLE the PASSIVE RELEASE...that should fix some problems with the PCI cards going off...

2. for PS/2 stability go in BIOS to PNP/PCI CONFIGURATION set RESOURCES CONTROLLED BY on MANUAL and IRQ-12 set on LEGACY ISA!!! also ENABLE the ASSIGN IRQ FOR USB...

That's really interesting!
Currently my USB is not cutting out, but when it starts going off again I'll try it.

Thanks!
