Overclock resulted in computer running very slowly

post #1 of 13
Thread Starter 
I noticed that when i loaded Orthos fully CPU-Z showed my VCore dropping from 1.49(ish) to about 1.42, my VCore in bios was set to 1.5. I decided that i could get away with increasing my VCore to 1.51, and managed to get my E6600 up to 3.5Ghz as a result.

It was running stable under orthos after a 2 hours (it used to crash within minutes at 3.5Ghz before i upped my vcore), and CPU -Z wasshowing my vcore dropping from just over 1.5v to just under it under load.

The problems arose when i noticed that my PCI-E Express wireless ethernet card wsa no longer showing up, and i brought my computer back down to 2.4Ghz, and decreased my vcore back to where it had been before. still no wireless internet.

I switched the card to my 2nd PCI-E Express slot and i managed to get internet, however my computer was running very slowly, unable to open 2 folders, and every click taking about 15 seconds to register. i restarted my computer and managed to start it in safe mode, everything seems ok, however when i got it to start normally it said that windows was missing some configuration files and i need to repair windows. i cleared my CMOS, and managed to get windows tp boot, however it is still running really slowly, much more slowly than my 9 year old laptop (on which i am writing this).

It takes about 5 minutes to open internet explorer, and about 10 mintues to close it.

have i fried my motherboard and/or CPU? or is this something that i can fix? It runs at a fairly normal speed in safe mode, why cant i make it run fast normally?

(I should point out i'm using XP Pro 32 bit with SP3.)

Very strange indeed, you say you lost your internet connection on your card which was connected to a pci-express slot. Did you have your pci-express bus set to 100 or auto? 1.5v is max for c2d on the 65nm process so you should be fine there, I didnt see you post any temps though, what was your idle temp and your load temp before and during running orthos? Run the checkdisk in a command prompt and see if that finds any errors, also see how fragmented your HD is although I dont see how that would be effected. It is likely that your motherboard may have been damaged but we should definately rule out everything else first.

my idle temps were about 40c, my load was 59c, so i should be fine there. the strange thing is that now i have it completely reset to all stock settings, and while it takes a long time to open up programs, it is able to do 1M on Super Pi in around 21 secs, and seems to be able to run on Orthos just fine.

My HDD's are ok frag wise, i check that every few weeks.

This is really starting to frustrate me now, i cant see why it wouldnt want to work

was your ram unstable at anypoint, did you overclock your ram at all and what are your ram timings?

my ram seems to be fine, its times were 5-5-5-15. its only running at about 34mhz above what its rated to do.

my PCI Express freq is set to 100 in bios

i ran checkdisk on my 3 hard drives and that showed nothing to be wring.

The strange thing that i've noticed is that my computer doesnt sound like its ever getting above idle. even if i turn the fan on my tuniq up full it doesnt actually spin any faster.

this is leading me to believe that i have a motherboard problem, although i'm not basing this on any experiences, just a hunch. I'm guessing that even if i had a CPU problem my fan would stil spin up when i increase the load (my fan is plugged into my motherboard)

thats a good question, was was about to ask if that could be a problem. its only 450W, could i have burnt it out or something? it was only a marginal increase in power that i asked for but it could haev been the killer difference.

I'm not running a powerful videocard but i do have quite a few cards in my PCI slots (TV card, X-Fi, Wireless LAN card, USB 2 card), as well as 3 hard drives, 2 DVD drives and a floppy drive, aloing with quite a few fans and some lights.

450w should be able to handle that... of course that depends on the efficiency...

i personally don't like under-consistant brands like tagan and hyundai for example. the voltage may be the same but you may want to test all the lines for the amps with a multimeter. just a hunch

edit: if you check my system \\/ , i have gone a little overboard on the power, but better safe than sorry has saved my countless times before.
