Games Crashing

[Ra^Groz]

So for the longest time hl2.exe would stop working. Then I switched from Vista 32bit to Windows7 64bit. Still continued to crash. Did a memtest, my RAM is good. My L4D2.exe was crashing as well when I played and had the video settings anywhere above the lowest. I just got a new video card. An ATI 5770. I had an Nvidia 7950gt. I haven't got an Hl2.exe error yet and I have been playing with basically full video settings. However I am still getting L4D2.exe error when my settings are at recommended(medium-high). Anyone else getting this error with L4D2 and same or congruent video card?

My Computer:
Cooler Master Mid-Tower Case
AMD Athlon 64 X2 Dual Core Processor 6000+ 3.01 Ghz
G.Skill 2GB 240-pin DDR2 SDRAM DDR2 800 (PC2 6400)
Samsung 500GB 7200 RPM SATA 3.0Gb/s HDD
Rosewill Stallion Series RD400-2-SB 400W ATX V2.2 Power Supply
GIGABYTE Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported
Acer 23" 16:9 aspect ratio and 1920 x 1080 resolution 40000:1 contrast ratio.
Windows 7 64-bit Professional

Can I get some opinions on what it might be? Only thing I am thinking of it could be is I need more RAM which I plan on doing as a Christmas gift to myself which is why I got 64 bit Windows7. Anyone else think that would solve it? How much are you all running RAM wise?

EDIT: The error just says. "L4D2.exe(or HL2.exe) has stopped working." My computer used to go blue screen then restart sometimes but after I upgraded to windows7 it hasn't don't that. Only quits me out of the game and shows the error.

Try upgrading your PSU, id say your +12 rails on your current PSU dont have enough juice

Taken from ATI's website:
-450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

A bad or not powerful enough PSU can make your system do strange things

And regardless, yes get at least 4gb Ram.. so cheap

is just the game crashing, or is your whole system locking up?

I'm going to blame the Rosewill 400W PSU.

ddr2 prices have shot up recently, because of a "shortage."

Game just shuts off. It goes to desktop and a L4D2.exe or HL2.exe came up and said that .exe has stopped working. With vista it was restarting my computer. So far with windows7 it hasn't restarted yet. Just get the error.

Yeah I noticed that, it went down to about $20 now up to about $50 for the same one I have in my system when I went to buy it. So I am going to wait and see if the price drops back down.

Hmm. Guess it is worth a try haha. Any recommendations on a pretty good power supply that isn't expensive?

Maybe one of these, though I'm not particularly well versed on power supplies. Also, how much you're willing to spend would be good to know.

Remember that the PSU is the heart and soul of your computer, giving all your high end components their juice. If you have a bad PSU or one from a cheap company, that "advertises" a certain wattage usually they dont do what they say. Can't hold a load, or the voltages are too low.

You should always have more than enough than not enough

This one is a steal. OCZ makes great products:

i'd definately get one if i needed it

Good point. I might run dual cards come christmas. Might get my girlfriend to buy me another for the heck of it haha.

Just got my 700W power supply in the mail. Put it in my computer. Tried to play Left 4 Dead 2. And it keeps freezing and crashing. Uninstalled and reinstalled it also.

Edit: Also got Crysis since it was 50% off. I tried to play it the other day on single player. Game also froze and crashed. (this was before new power supply)

Try using your old GPU and see if it still crashes.

[Ra^Groz]

Still crashes.
