Extremely Slow data transfer rates

[Fireball]

Hey guys!

Quick question :

I recently Overclocked my PC (see my sig below)
The problem is, my transfer rates are becoming ludacrisly slow. Earlier today, I tried writing 3.5 GB to a DVD. Where it usually took about 15 min, it took over an hour!
That, and when I try copying data from one drive to another, or even just on the same drive, my PC slows down to the point of stalling. My mouse lags, my screen lags, hell, even my sound lags!

It was never this way, I don't understand what the problem could be. I haven't installed any new hardware, or software for that matter.
The funny thing is, I'm not struggling to play any of my usual games (like COD 5). They all perform at their usual FPS. It's only when I actually need to physically transfer data that my PC slows down like this. Oh, and my start-up is unusually slow, even after a full registry scan and disabling any unwanted start-up programs.

As usual, any help is greatly appreciated.
Thanks guys! Untill next time

Ok there might be a few things.

Your CPU might be overheating and this would throttle the system back,thus causing a slow down of the system.
Turn off throttle in the BIOS and C1Executive bit. there are one or two other things to turn off but I can't think of them and these are the main culprits.

Then we need to look at the card-try reduce the RAM timings of the card and see if that helps although I think the issue lies in the motherboard.

Run memtest and see if your RAM is 100s.

Yea dude somethings dodge there ? check as above please and also let us know what Antivirus , OS and burning software you are using.

Might be that your drive is giving problems . But check mem first. And make sure your Antivirus is not running a scan.

Hey Guys. After much research and painstakingly sifting through my PC settings, I found the source of my frustration. There was nothing wrong with the drive, it was (shockingly! ) thanks to Windows. Turns out if you get a few CRC error messages, it changes your DMA settings to the older PIO mode. All that was needed was to go to Device Manager --> IDE ATA/ATAPI controllers and uninstall all my channels. After a reboot, windows detected them again and changed my settings to UDMA 5. Now everything is sorted! I can listen to music while I burn discs, heck, I can play Crysis while doing it!

Joy!
