Hey guys,

I don't know what really happened. I've been having a lot of issues with my PC since I built it a month ago.

Abit IP-35E
Q6600@2.4GHz w/ Stock
MCI GeForce8800GT OC
Rosewell 750W PSU
OCZ Vista Upgrade PC6400 5-6-6-18 DDR2 2x2GB
WD 160GB 7200 RPM SATA

After I put my PC together, I installed Windows XP, had issues with a black screen appearing during games. My problem seemed to go away (after days of troubleshooting with other techforums help) after I uninstalled .NET Framework 2.0 and 3.0. After this issue was almost a dead topic, I for some reason got an awesome brainstorm idea, "Hey let's see how Vista Ultimate 64-bit Edition ran on my PC" since I do a lot of photo editing and whatnot. Well, I went ahead and did that, I dual-booted. After the dual-boot, I set up Vista, everything runs smooth, got a 5.9 on Windows Experience, and then I wanted to use some other programs and play some games that I didn't have installed on the 64-bit, and Windows froze at splash screen. After reboot, it just kind of 'lagged' through the Splash screen with low framerate, and I was able to get into XPx86, and everything seems to be going okay... and then during a game I was playing, I get a purple screen. (This was in XP, not Vista). This purple screen had no writing, no menus, just a solid lavender screen. In the background I could still hear my menu and games going on, and it seemed like the opacity of the purple screen was 98%, for once in a while a glitch or something will shine through.

I updated the drivers to the newest form, and then tried again, and it all seemed fine for a few days, then when I was playing another game I got the screen again. Then I restarted, and was in the process of unloading the drivers, and I purple screened on Device Manager.

After reading a few forums, some said the dual-boot caused it, so I tried to follow some steps to uninstall Vista, but the shell line can't be run from a non-64-bit platform.

I think my question is, does anyone know what is causing this purple screen issue? I haven't had this occur yet while using Vista, but then again, I don't have any real games or programs installed on it.

And another question would be: is there a way to remove Vista 64-bit edition, or am I stuck with no choice but format both partitions?

Thanks for any help.

You can format the vista partition easy. And I think your PSU is the culprit. Rosewill is junk.

Formatting the Vista partition wouldn't solve my problem, because it links itself to my previous XP boot. And other ppl talk about Rosewill being junk, but it's still $150 PSU and unless there's proof, you can't just point fingers based on name.

Well formatting probably wont help but you can do it without messing things up.

I dont care if you paid $15000 for a PSU, if it is of junk quality it wont hang with todays game.


Your problem sounds like a classic underpowered system.

Sorry I cant wave some magical answer at you. You wanted help and I offered it.

Test the memory with memtest86+.

For laughs, change that lavender to another color:

^ Agreed. The PSU is cr@p. Get a good top tire PSU listed here:

I recomend PP&C 610 or Corsair 520HX/550VX/450VX

I don't understand how you can immediately jump on the power supply as the culprit when it worked fine before the Vista install and the problem only occurs in XP. I'm not necessarily disputing your assertion, just asking for quantitative justification. I find it hard to believe that troubleshooting power supplies is a matter of parts replacement versus component testing to determine whatis actually wrong.

Epicus, check your voltages in bios and speedfan. Then use speedfan to graph voltages under load. At the very least, you get an indication if voltages are in spec and thus if the power supply is holding up under load - at least under the limitations of the software and monitors.

Probably because he is only playing games and such "stressing" in XP. He said he dont have any real games or apps on Vista. If he did when they stress it would cause problems. Pretty much when you have a crappy brand PSU and you have trouble in games, its a no brainer what the problem is. You would know that if you had very much experience.

Well I just had the problem occur under Vista. Although instead of lavender BSOD, my screen just went black, and I was hardly stressing the PC. I was idling with a game menu screen open. With Speedfan and BIOS, my PSU never drops between the recommended voltages by my mobo company.

CPU Core: 1.18V
DDR2 Voltage: 1.97V
CPU VTT Voltage: 1.18V
MCH 1.25V Voltage: 1.32V
ATX 12+V: 12.21V
ATX +3.3V: 3.33V

What I don't understand is if this company can't even supply a PSU that works on a computer, as everyone is so stating, why are they still in business? Because they scam people into buying their PSU?

And replying to the BSOD color changer... I don't think it's even a genuine BSOD, like I said, it has no text. It's just a solid lavender screen, othertimes just solid black.

Rosewill works great for your basic internet machine. I have seen 100s of posts about problems with rosewill in gaming machines.

Its not software since you tried XP and Vista. So it is hardware. Either your card is chit "unlikely" or your PSU isnt up to the task. You can get a good namebrand PSU in the $60 range. Or you can Rma your card and pay shipping both ways and still have the same problem.

Ya tipical underpower GPU results. Change that PSU before you go crazy. Sell that Rosewill on Ebay.

Agreed can the PSU, get atleast a tier 3 or better.

I am considering this one, although the price is kind of steep, I do not want to go through something like this again, if this is indeed the problem...

Hey I have something for you to try. Install all the updates to vista, including sp1 and directx 9 (yes 9). Then just search for your game and program executables and run them (you may want to move your saved game data from the windows xp user folder to the windows vista user folder). This should allow you to play all your games and run all your programs. This is what I do, and I don't have a problem.

Here's a cheaper corsair to check out: http://www.newegg.com/Product/Prod [...] 6817139004

If modular cables are of the utmost importance, the HX-520 is the PSU for you. Otherwise the VX-550 (which is not modular) is somewhat better for high power-drawing systems. Your system is not really "high power-drawing" so either PSU is good enough. I can speak from personal experience that the HX-520 is very quiet, and very stable. The VX-550 should be similar.
