crc errors?!?!?

every time i download files, and i try to run/uncompress them after the download is complete, it always says that the file is corrupted or has CRC errors. whyyyyy??!! it seems to happen mostly on larger files (ie. Deus Ex patch, 36MB; Mechwarrior 4 Demo 68MB)...

Here's my system specs:
PIII 800EB
Intel D815EEA Motherboard
256MB PC-133 SDRAM
Maxtor 30.7GB ATA-100 7200rpm
Maxtor 8.4GB ATA-66 5400rpm
Sony 32X CD-ROM
Plextor 12/10/32A CDRW
3D Prophet II MX
Intel Pro 10/100 NIC (integrated on motherboard)
Sound Blaster Live
Windows ME

I'm on a LAN... there is one computer connected directly to cable modem, and my system is connected to that computer via cross-wire RJ45 cables... and we share the internet connection... is that where my problem is?? the thing is, everything was ok before... i could download no problem... the problem just started today... so i reformatted and i still get the same problem... can anyone tell me what's causing the crc errors and offer any advice?

thanks.
 
CRC is Cyclical Reundancy Check. It provides error correction and verification info to make sure that the data frame is received correctly. So the data packeting is being sent with an error. or without the CRC at the end of each packet... now, to fix this problem... Im not really sure. it could have to do with your little network setup.
 
Are you using a download manager, or any kind of downloader?

Download managers that do segementing might corrupt files sometimes. For big downloads, I tend to just seralize the download to avoid the problem.

Other than that, since any accepted TCP packet should in theory already passed CRC before it gets appended to your file, something on the network may be screwing up your incoming data. This can include some virus scanners or whatever software/hardware that will filter/examine the data.
 
actually, the problem was just that i had a bad stick of ram...
i went and exchanged it for a new one and now everything works just fine.

thanks for everyone's help though. 🙂
