Generally speaking you don't need to set jumpers on a SATA drive. On SATA hard drives, jumper settings enable or disable enterprise-level features.
SSC Mode (Default 1): spread spectrum clocking feature enabled
or disabled. Default 1 setting is disabled or jumper shunt placed
on pins 1–2. Removing the jumper enables the spread spectrum
clocking feature.
SSC Mode (Default 2): spread spectrum clocking feature enabled
or disabled. Default 2 setting is disabled or no jumper shunt
placed on pins 1–2. Adding the jumper to pins 1–2 enables the
spread spectrum clocking feature.
PM2 Enabled Mode: to enable power-up in standby (power
management 2 or PM2) mode, place a jumper on pins 3–4.
This mode enables controlled spinup by spinup command
in accordance with ATA standard and is mainly for
server/workstation environments operating in multiple-drive.
I am not sure how relevant this is to your problem?
It's pretty hard to troubleshoot an overclocked system when the overclock could be part of the equation. First rule - start with a stable system before you overclock!!! Go into BIOS. Press F5. Load Defaults and lets start again tomorrow.
Yep... I will do that at lunch time. But I can already guarantee you this issue was present at default mode a few days ago.
I hope you are right and I'm wrong and something wierd happened. I just find it wierd that if OC'ing was the issue, it would cause it "ONLY" on the bad account and not on a fresh one.
Isn't the problem that a New Account becomes a "bad" account after a short period of time? And this despite you having re-installed Vista and created new accounts?
And I am not saying that overclocking is the culprit. I don't think it is causing that particular problem ( I don't KNOW what is causing the problem), BUT, first things first. The benefits you get from overstressing your system do not include resolving this problem and it becomes one more factor to consider. The old KISS principal should apply (Keep It Simple S**) The less you have to worry about the more likely you are to resolve the issue.
Just a little explanation on PC Troubleshooting should help.
Step 1. Get rid of superfluous confusing stuff, such as "Is it the O/s" or "Is it Software" or Is it Hardware"
Some problems are obviously software or hardware. If they aren't so obvious
If you suspect Hardware - Cables, Disk Drives, RAM, Graphics cards, sound cards.
Look at installed Software, (Nero and Norton are often culprits) Codecs etc. If it is O/s and not obvious, do a fresh install.
Each step is a small one and can be frustrating. Try to be patient and logical. The process is one of elimination, like a detective. Try not to complicate the search by introducing new variables. Remove variables from the equation by swapping RAM, removing the Graphic Card and running on-board Graphics, same with the Audio card. Leave them out until the problemis resolved. It could be a combination, rather than a single factor.
