I'm desperate - System Interrupts (Windows 7)

[SE_Saga]

Thanks ua549 and MrDigital.

As I hinted at the end of my last post, I'm leaning towards a hardware issue as well.

I'll try the "turn everything off and see if it persists" option.

My mother won't have any music for a few days, but she can't really hear too much music right now since the Media Player starts to stutter halfway through the songs, so she'd rather wait and see if this gets fixed, I'm sure.

I'll report in a few days... thanks again.

UPDATE: As promised, here I am to report on my findings.

I went into the BIOS and turned off everything I could think of. I then tried the computer out for 48h and the problem disappeared.

I then turned on the on-board audio, and waited another 48h. Flawless.

Finally, I turned on the USB Controller option and, again, no sign of any problems for the next 48h.

Today, I turned on the "USB 2.0 Support" option... and about 2 to 3 hours after, the CPU jumped to 100% and System Interrupts is the culprit, as expected.

I still haven't turned everything on (like "USB Legacy Support" for instance) but it seems I've found the problem... my question now is, how do I fix it?

Well, turning it off works, of course, but how can I have 2.0 USB support without going into the BIOS? Is there a way to fix this other than to buy a new mobo? And while I'm at it, what could have caused this?

If she has a free PCI slot available, buy a usb card and use it: http://www.newegg.com/Product/Produc...-010-_-Product cheapie, but worth a try. There are better available @ newegg.

The mobo has:

- 1 x PCI Express x16 slot
- 1 x PCI Express x1 slot
- 2 x PCI slots

All of them are empty, so shouldn't be a problem.

She has an external hard drive and wireless internet, so those are the only USB devices that would get affected. I don't think the internet will be any slower because of this (at least, I didn't notice any difference), but the transfers between the internal and external hard drives may suffer a bit... but probably nothing she'll notice too much.

Well, that's a wrap then.

I'd like to thank everyone for your patience, and suggestions.

I see now that this should probably be in Technical Support, not the OS forum, but at first I really thought it was Windows Vista and 7 who were acting up.

I'll look for a PCI USB device but, until then, she'll live with USB 1.0
