Radeon 4650HD AGP XP crashes when gaming

October 16, 2010 at 11:27:11
Specs: Windows XP Pro 32bit, P4 3.0 ghz, 1GB
Hi all,

I just bought a brand new Sapphire 4650HD AGP 8X video card for my old P4 system.
My motherboard is an Abit IS7-E
3.0ghz P4
420W Power Supply
Updated Intel Chipset drivers

Reformatted from Windows 7 back to XP PRO SP3 - 32bit. Went fine.
Downloaded the new (official) driver's from the ATI site for XP 32bit - 10.9 Catalyst drivers.
All worked fine. Installed Steam, games ran BUTTER smooth.

But when I play games (like Counter Strike Source) or even mess around with Steam Settings, about 20 minutes in, it completely crashes, shuts off and restarts the computer! I'm assuming this comes from the video card alone. Does anyone know what is going on? I've been searching for answers for hours on end now. Help?

EDIT:::: Computer Crashes when surfing the internet after 30 mins! Whats going on?!

Temp readings:
TMPINI1 - 24 C
TMPINI2 - 44 C
TMPINI3 - 37 C

The temperatures are more than fine, they're all running very cool in fact, mainly because I just replaced the case fans with brand new ones, and the north bridge fan. And I cleaned out the whole tower.

As for other games, I don't play other games other than CS:S on Steam. Runs its perfectly besides the fact that my computer restarts after a while. It just seems like it may be the drivers that aren't compatible. Sometimes (not often as the gaming issue) my computer even restarts when watching videos on Youtube or just general browsing. But how is this possible when the drivers came from ATI's site? Any more suggestions??? Help!

Just a shot in the dark, but you say you have a 420 watt psu. It is possible that the psu is getting overheated. Even though it's 420 watts doesn't mean very much. It depends on how the 12 volt rails are configured. These days a single 12 volt rail is the preferred setup. You added a card that draws additional power. Power failure is the leading cause of computer problems. You might want to try a newer psu. just my 2 cents.

hd 4650 agp use less than 45w (30w), even a cheapo psu can run it (420w +12v@10A). If it is a driver issue try to un-install ATi driver and let the system run for 1hour without ATi driver and see what happens.

Thanks for the insight guys.

I just put in an extra 2GB of ram and now the crash doesn't happen as often anymore, but it still DOES happen, only this time during Gaming and messing with Steam settings only. Grasshopper's theory MAY be correct, but then again on the side of the VC box it says "400W or greater" power supply, and I have 420W....

One thing I did notice was the 6 pin connector on the VC itself. My power supply does not have a 6 pin connector (could be a reason?), but luckily Sapphire threw in a 6-pin-to-molex connector cable for old PSUs like mine. On the end of that VC cable though, inside the molex it only had 3 metal pins, inside a 4 pin body. The 4th pin hole has nothing there, its empty...strange. I'm wondering if that has to do something with it or nothing at all.

kuwese, I'm gonna try that right now and I will post up results.

In the meantime, I got "Windows recovered from a serious error" issue after it restarted and this was the code:
BCCode : 10000050 BCP1 : AC0060A8 BCP2 : 00000000 BCP3 : AC04578B
BCP4 : 00000000 OSVer : 5_1_2600 SP : 3_0 Product : 256_1

Ok I just uninstalled the ATI drivers and ran the regular XP VGA drivers for about an hour. It crashed about 30 mins in just browsing the internet. So I'm guessing the 420W power supply isn't enough....will a 500W do?

Look for a new psu that has only 1 12 volt rail. Corsair makes a great power supply.


Check these out.

Thanks. But that link redirects me right back to this thread....(?)

What about this one?

Wow I wish I could've checked more thoroughly. The whole reason why it crashed wasnt because of the VC or power supply, it was the RAM. Never mix ram! I mixed different brand RAM and got crashes (single channel with dual channel) and finally figured it out.

So if anyone is still reading this and wants to buy a Radeon 4650 HD for an AGP equipped computer, dont hesitate. It performs beautifully on an old P4 system and runs fine even on a 420W PSU. Definitely one of the best AGP cards out there.
