New 6600GT, System shuts off !Updated! Help Plz

[hallycat]

Installed the Leadtek 6600 GT today and was playing HL2 ( no CD ) for awhile off and on. I decided to see how Halo looked and I played for a bit and the system shut itself off. I had split the power supply cable with the DVD drive and thought maybe that was the problem with the drive in use so I switched it to the second hard drive which is pretty much just storage. It happened again. I then tried HL2 again with no CD in the drive and it still shut off. Temps on the new card were great, system was getting hot but I used the ghetto cooler method ( side of case off, floor fan on which is no unusual when playing)

Power Supply is 350 Watts. P4 2 GIG on and Intel D850EMV2 with 768 MB's PC800 RAMBUS, SB Live Platinum, DVD Drive, DVD RW Drive Two IDE HD's and a floppy. I will put the old Geforce 4 MX440 back in tomorrow to verify ( I need to get dinner and a life ) but I am thinking I need a bigger PSU, especially with every cable in use and one split.
Opinions?

I have a Leadtek 6600GT and if I could find my manual I could tell you for certain, but I am 90% sure it highly recommends a dedicated power cable for just the vid card. I really have no clue if thats your problem or not. Maybe I read what you wrote wrong, but it sounds like youre still splitting the power between vid card and something whether it be DVD drive or HDD. Otherwise, maybe you are on the right track with a totally new PSU.

I did say I was AFK but dinner is a cooking
You read right, it's on the splitter with the secondary HDD.
I happen to have the manual handy as the box is laying on the floor where I left it but of course I didn't read it yet. It says use the supplied splitter or if there is an unused cable to use that. Nothing unused. I think there's just too much going on and have seen others saying you need more power for the powered cards.

yes im pretty sure that u require a bigger PSU....400W would be required since u have quite alot of peripherals

Ok, this morning system shut off while I was just reading web pages so I put the old card back in. It shut off again while playing Halo. I think the 3year old PSU was on it's way out and the new card just hastened it along. It must have a shutdown on overload feature. I'll either take a ride to Microcenter or Compusa over the next two days or order one from Newegg and just stay on the lappy till it comes. Would love to test to be sure that it is PSU but nothing around here to throw in. Any thoughts?

if u have another machine u can test the 6600GT there...if it still gives problems there it could be the GPU thats giving problems but its highly unlikely...shutting off suddenly is generally due to a small PSU.

It's not the Video, I put the old GF4 MX440 back in and it did it again.

Get this from CompUSA

And this is how you do it: Go to the business/corporate desk & setup an account with one of those salespeople. Tell them you need an online account to access the business website so you can order parts for your computers. Then you can just call your salesperson whenever you need something, & they can order it for you, & have it delivered to your house or the store for you to pick it up. You could order for yourself when you have the account setup but it is to your advantage to call your salesperson first.
