Blue screen (overheating GPU I believe) need help with upgrades

[xcrafter2]

Motherboard : MSI 7379
RAM : 3gb corsair
gpu: nvidia geforce 210
cpu: intel core duo E8400 3ghz
psu: apevia atx-cw420w

Problem: blue screens randomly (usually over 50c gpu temp) I keep a fan on it and it keep it under 50 most of the time, but now it's randomly doing it even in the 40s C range.
The error is 'uncorrectable hardware error'.

Anyway I was looking to upgrade and having been doing some browsing, my budget is 150 absolutely no higher, and I'm looking to replace my GPU with that. everything should be fine but I'm here to get some suggestions.
I'm running Diablo 3 and would like to be able to run it at max setttings, or near max. Any suggestions on brand or model card?

are you using windows 7 or vista? if so make sure hpet is enabled and matches your o.s bitrate... ie set it to 64 if you have 64bit o.s.
you will find it in bios under hpet or high precision event timer.
often this is the cause of random bsods and will have nothing to do with system temps... btw the 210 will do 100'c+ b4 it throttles so 50 is well withing spec and should not be causing the shutdowns...

also next time you boot press f8 to get the boot menu yo open ( the 1 that gives you safe mode) you should see an option to turn off auto restart on error. this will allow you to see the error number and text which can point you in the direction of a fix... or you can get blue screen viewer this will let you read the bsod logs in windows.

also that powersupply is a fire hazard. get it out of your system as soon as you can...
newegg stopped selling it a week after they started and have not stocked it since...
almost all have been returned blown... as there actually little more than 200w psu's and have been known to spontaneously catch fire. so if hpet isnt the problem then its likely the psu...
replace it with a decent 450w-550w unit which will cost between 50 and 70 bux.

which o.s you using as i get different results for xp and win 7 also is it 32 or 64 bit. and what service pack.
as windows has had some updates that deal specifically with 0x8e kernal mode exemptions on win 7

win 7 ult 32 bit is what I use.
also
0x00000124, 0x00000000, 0x8694F024, 0xB2000040, 0x00000800
