So, I have a couple of problems...

'afternoon, everyone.

I've had this T42 of mine for several years now, and I love it. She's solid, performs well despite her age, and is pretty slim/light despite the time period of manufacture. I do have a few things I would like to ask, though...

First off, my specs:

2378-FVU
Dothan @1.7ghz, not overclocked or undervolted (I did undervolt before, but got tired of NHC eating resources for minimal benefit, since the laptop cools fine)
2gigs of DDR400 RAM (not at full speed of course...)
160gb Hitachi HDD (biggest IDE drive from the only hard drive vendor I trust)
Radeon 9600 (overclocked while gaming), using Omega drivers
14" XGA panel
Intel 2200 BG wireless/Intel PRO/1000 wired

Second, current problems:

1: Whenever I try to put the machine into standby or hibernation, about half the time it'll go through most of the motions, then freeze without going completely in (both power lights still on). There's no choice at this point except to completely shut it off and restart it when I need it next.
There doesn't seem to be any rhyme nor reason to this. It happens regardless of how long the laptop has been booted up, whether I was just gaming or word processing or whatever, doesn't matter if wireless is on or off, etc. When it first started happening, I thought I had a bad driver or good old bitrot had set in (my Windows installation was a good year and a half old at that point), so I reinstalled. No effect. That was several months ago, I've just been putting up with it...the problem hasn't gotten better or worse.

2: Occasionally, usually while browsing Youtube videos, my screen will inexplicably go black, usually just at the moment a new video is opened. Trying to manually reset the display adapter (I have the function hotkeyed via Ati Tray Tools) does nothing; the laptop is completely unresponsive. This is on Firefox, with the newest Flash plugin.

I'd like to point out that I have no problems while picking up the laptop and moving it, so I don't think either of the problems have to do with a loose video chip. I do need to run a full sweep with memcheck, since one of my RAM modules is some crappy offbrand. The laptop seems to run fine other than the above problems, though, and I would think that bad memory would cause serious problems when I was doing something memory intensive, like gaming. Especially while playing Oblivion, it pushes everything on this machine pretty hard. As mentioned above, the laptop cools fine (Arctic Silver on the CPU and video, fan working perfectly), and neither of those happen during high-heat operation anyway...
Any ideas?

Thirdly...
I'm thinking very hard about doing a forced overclock with one of the methods in this thread. This of course won't do anything for video performance though; any way I can get this old 9600 to crank out more frames/second? I have it overclocked stably at 400/240 or so, which definitely makes a difference in its performance...anything else I can do? It's old hardware I know, just thought I'd ask :v

Thanks in advance for any assistance!
