Fragging after heatsink replacment.

Hi Everyone.after a long time of being away from the Original xbox I decided to buy one and get back into it for some of the games I have. I got a v1.0 and instantly removed the Clock Cap. I then softmodded it and tsop flashed successfully the latest cerbios v2.02 UDMA5 version (I also replaced the iIDE cable at the same time. everything was fine apart from the loud whine coming from the GPU fan so I bought the v1.2+ heatsink and went and replaced it in the Xbox today. After putting it all back together it turned on and booted into the dash fine (XBMC4Gamers) but after a minute of sitting there it glitched out and it restarted 3 times before doing the red/green flashing light.

I think I may have used bad thermal paste that may have been out of date.

I reused the metal clamp on the gpu.

I also repasted the CPU at the same time but when I went to reattach the clamp it didn't seem to clamp down fully on the CPU either.

could the BIOS get damaged while the Xbox is running causing it to now frag?

does anyone have any advice on this?

i had this problem before and it was because i got some of the solvent under the gpu. drove me crazy for weeks trying to figure it out because the xbox has sentimental value to me. take the mobo out of the case, hold it vertical over the sink, and squirt rubbing alcohol all over above that chip. do that a pretty good bit. then take a hair dryer and keep heating it up to dry the alcohol. get it just hot enough so the u can't hold your hand on it for extended time comfortably. let it cool off and then do it again. do that about 3 times and then reassemble to see if the problem is still there.

Thanks I'll give this a try.

best thing to do is not try to remove the heatsink in the 1st place. that old thermal glue still works surprisingly well. if u have to replace a 1.0 heatsink with a newer model then u don't really have a choice though.

I finally got the new Thermal paste last night and done this today. plugged in the machine and it's all back up and running. once again thank you bulkchart32 for that advice.

you're very welcome gary. glad i could help! the game saves on my og xbox and the dates on them remind me of a different time in my life. so it was really important to me to get that xbox working again even though i had others. took me weeks to figure it out and, i honestly don't remember how i figured it out(i think it was from staring at the board multiple times) but, i just remember i did and it worked, thank heavens!

Seems odd to not change out thermal paste or glue after this long. I am starting research what all i want to do to mod my machine and i know typically when working with old electronics generally you change that out. I havent removed the cooler yet but now i will probably leave it alone

I agree that is seems odd but it still works surprisingly well and can cause problems if u try to redo it.

I have seen plenty of people twist and pull that heatsink off. Also more than a few that pry it off with a screwdriver…….. Amimals

This will incite the same issues that plague the 360, any of the solder points that were lightly iffy will be stressed and could break.

The only sensible way is to heat it with a heat gun from a rework station and it comes off easily once things get warm.
